Background and Objectives: Low-pressure pneumoperitoneum (PP) during robot-assisted radical prostatectomy (RARP) has been shown to improve postoperative recovery in patients with non-obesity. However, its efficacy in individuals with obesity remains unclear. This study aimed to evaluate postoperative outcomes in patients with obesity undergoing RARP with low-pressure (7 mmHg) versus standard-pressure (12 mmHg) PP. Materials and Methods: In this retrospective cohort study, 130 patients with obesity (BMI > 30 kg/m²) undergoing RARP were divided into low-pressure (n = 60) and standard-pressure (n = 70) groups. Postoperative recovery was assessed using the Quality of Recovery-15 (QoR-15) questionnaire on postoperative days (POD) 1, 3, and 30. Secondary outcomes included surgical workspace (SWS) scores, operative time, blood loss, intraoperative and postoperative complications, hospital stay, and pathological results. ANCOVA and chi-square tests were used for analysis. Results: QoR-15 scores were significantly higher in the low-pressure group on POD1 (123.58 vs. 111.41), POD3 (128.37 vs. 116.41), and POD30 (132.88 vs. 125.61; p < 0.001). Operative time (98.5 vs. 71.57 min; p < 0.001) and blood loss (129 vs. 97.07 mL; p = 0.039) were higher in the low-pressure group. SWS scores were lower in the low-pressure group (p < 0.001). There were no significant differences between groups in complication rates, hospital stay, or positive surgical margins. Conclusions: In patients with obesity undergoing RARP, low-pressure PP improves postoperative recovery without increasing complications. Despite longer operative times and higher blood loss, this approach is a viable option to enhance recovery in this population. Full article

Background: Prostate-specific membrane antigen (PSMA)-PET imaging has significantly improved prostate cancer (PCa) staging, yet its interpretation remains challenging, even for experienced specialists. No prior study has assessed urologists’ ability to interpret PSMA-PET. Methods: We conducted a multicenter prospective study involving 63 urologists from eight Italian institutions. Participants evaluated 20 PSMA-PET scans of high-risk PCa cases, with no clinical information provided. Proficiency was defined as correctly identifying at least two of three staging components (T, N, M) in ≥75% of cases. Associations between performance and factors such as hierarchy (resident vs. consultant), institution type, surgical volume, and multidisciplinary team (MDT) presence were analyzed using univariable and multivariable logistic regression. Results: Only one participant achieved full staging proficiency, while 44% reached the ≥75% threshold for partial (almost correct) staging. Urologists from centers with ≥300 PCa diagnoses per year demonstrated better T and M stage identification. Institutions with ≥150 robot-assisted radical prostatectomies (RARPs) per year and those with MDTs showed higher accuracy in M staging. No significant predictors of proficiency emerged in the multivariable analysis, although hierarchy and surgical volume approached significance for nodal metastasis detection. Conclusion: PSMA-PET interpretation is complex for urologists, with particular challenges in T and M staging. High institutional case volumes and MDT involvement may enhance interpretation skills. Structured training programs and increased exposure to multidisciplinary imaging discussions are essential to optimize urologists’ diagnostic proficiency and ultimately improve patient care.

Background/Objectives: Prostate cancer is the second most common malignancy in men, and robot-assisted radical prostatectomy (RARP) has become a preferred treatment for localized disease. Postoperative urinary continence is a key determinant of quality of life. The aim of this study was to evaluate the preoperative patient characteristics and multiparametric magnetic resonance imaging (mpMRI) data that determine early postoperative continence in patients who underwent robotic radical prostatectomy at our clinic. Methods: In this study, patients who underwent robotic radical prostatectomy at our clinic between March 2020 and June 2022 were evaluated. The patients’ demographic data, preoperative PSA levels, digital rectal examination findings, preoperative lower urinary tract symptoms, sexual function, mpMRI findings, Briganti scores, surgical techniques used during the procedure and postoperative continence status were assessed. Results: A total of 111 patients were included in the study. The mean age of the patients was 61.1 years. The median follow-up duration was twelve months. According to the postoperative continence status, 22% of the patients were incontinent, 53% had moderate continence and 24% were fully continent in the first month. At the third month, 16.8% of the patients were incontinent, 31.3% had moderate continence and 51.8% were fully continent. At the one-year postoperative follow-up, the percentages of incontinent, moderately continent and fully continent patients were 4.8%, 13.2% and 81.9%, respectively. Urethral width in mpMRI (p: 0.012), pelvic transverse (p: 0.002) and AP (anterior–posterior) diameters (p: 0.033), preoperative IPSS scores (p: 0.033) and the presence of bilateral nerve-sparing surgery (p: 0.047) were found to be associated with postoperative urinary continence. No significant differences were found between groups regarding the relationship of other parameters evaluated by mpMRI with continence. Conclusions: In our study, preoperative IPSS scores, urethral width in mpMRI, pelvic transverse and AP diameters and the performance of nerve-sparing surgery were associated with early postoperative continence. Further studies with larger patient populations are needed to better understand the long-term predictors of postoperative urinary incontinence following radical prostatectomy. Full article

Background/Objectives: This study evaluates and compares the diagnostic accuracy of [68Ga]Ga-PSMA-11 and [18F]F-PSMA-1007 for lymph node staging in patients with prostate cancer (PCa) scheduled for robot-assisted radical prostatectomy (RARP) and lymphadenectomy (LND). Methods: We retrospectively reviewed prospectively collected data on patients referred to our hospital from October 2020 to January 2023. We included all patients who underwent [68Ga]Ga-PSMA-11 or [18F]F-PSMA-1007 PET/CT for primary staging and subsequently had RARP with concomitant LND. The maximum standard uptake value (SUVmax) for lymph nodes (LNs) and the SUV node-to-background ratio were reported. Two different cut-off values for the SUV node-to-background ratio (i.e., ≥2 vs. <2 and ≥15.5 vs. <15.5) were used to evaluate the diagnostic performance of both tracers. The first cut-off was empirically chosen, while the second was based on Liu’s method. Results: A total of 156 patients were included (median age: 67 years). Among them, 83 underwent [68Ga]Ga-PSMA-11 and 73 underwent [18F]F-PSMA-1007 PET/CT. Suspicious lymph nodes were identified in 21 patients (13.5%). Pathological nodal involvement (pN1) was confirmed in 25 cases (16%). Of the 21 patients with suspicious pathological lymph nodes on PSMA PET/CT, 9 (42.9%) had positive nodes on the final pathology report. With an SUV node-to-background ratio cut-off of ≥2, [68Ga]Ga-PSMA-11 showed 37.5% sensitivity (SE) and 98.5% specificity(SP), while [18F]F-PSMA-1007 demonstrated 33.3% SE and 100% SP. Using the ≥15.5 cut-off, SE and SP were 31.3% and 100% for [68Ga]Ga-PSMA-11 and 11.1% and 100% for [18F]F-PSMA-1007, respectively. Conclusions: [18F]F-PSMA-1007 PET/CT showed, even if not statistically significantly, slightly lower SE and higher SP for nodal staging compared to [68Ga]Ga-PSMA-11 PET/CT, irrespective of the SUV ratio used.

Background: Cold dissection (CD) during nerve-sparing robot-assisted radical prostatectomy (nsRARP) in patients with prostate cancer has been proposed to improve functional outcomes by reducing the thermal damage to neurovascular bundles (NVBs). This study compares the impact of CD versus thermal dissection (TD) on postoperative early continence and erectile function recovery. Methods: A prospective comparative analysis was conducted on patients undergoing nsRARP, comparing CD and TD techniques. Continence was assessed at 15, 30, and 90 days, while erectile function was evaluated at 30, 90, and 180 days using IIEF-5 scores. Logistic and linear regression analyses were performed to identify predictors of functional recovery. Results: CD significantly improved early continence at 15 and 30 days (p < 0.05), although the difference diminished by 90 days. Erectile function recovery was consistently higher in the CD group at all time points (p < 0.01). Age negatively impacted continence and erectile function recovery, while preoperative IIEF-5 scores were strong predictors of erectile function. Prostate volume, BMI, and metabolic syndrome showed no significant influence on outcomes. Conclusions: CD enhances early continence and erectile function recovery following nsRARP by preserving NVBs and minimizing thermal damage. This technique offers a valuable approach to improving patient functional outcomes. Further studies are required to validate its long-term benefits. Full article

Background/Objectives: Radical prostatectomy is a standard treatment for localized prostate cancer. We aimed to compare perioperative outcomes and functional results between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP). Methods: A retrospective analysis was conducted on 120 patients who underwent LRP (n = 60) or RARP (n = 60). Perioperative parameters, including operative time, hospitalization duration, blood transfusion rate, wound healing complications, urinary catheterization duration, urinary tract infections (UTIs), and urinary incontinence, were assessed. Statistical analyses included Student’s t-, Mann–Whitney U, and χ² tests. Results: RARP was associated with significantly shorter operative time, compared with LRP (147.25 vs. 188.30 min, p < 0.0001). No significant differences were observed in hospitalization duration, transfusion rates, or overall complication rates. However, impaired wound healing was less frequent in the RARP group, with a 10% lower incidence, compared with the LRP group (p = 0.0946). Similarly, UTIs occurred less often in the RARP group (six vs. one cases; p = 0.0544). Urinary incontinence was significantly less frequent following RARP, with its incidence being more than twice as low, compared with the LRP group (p = 0.0032). Additionally, the RARP group had significantly lower International Prostate Symptom Scores, with a mean difference of 7.83 points, indicating improved urinary function. No significant differences were found in sexual function (IIEF-5 scores). Conclusions: RARP offers advantages over LRP, including reduced operative time, lower rates of wound healing complications, decreased incidence of urinary incontinence, and improved postoperative urinary function. Further studies with larger cohorts are warranted to confirm these findings and assess long-term functional and oncological outcomes. Full article

Background and Objectives: The limited literature on the significance and risk factors of intraoperative anastomotic leakage (IAL) following Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) highlights the need for further investigation. This study aimed to assess the incidence of IAL, identify its associated risk factors, and evaluate its clinical implications. Materials and Methods: Patients with prostate adenocarcinoma who underwent Rs-RARP performed by a single surgeon between February 2015 and August 2023 were included in this study. Positive IAL was defined as the presence of anastomotic leakage identified through a water injection test performed immediately after vesicourethral anastomosis (VUA). Postoperative urinary continence was defined as the use of no pads or only a safety pad. Patients were categorized into two groups: those with positive IAL and those without. Immediate repair was performed in cases of positive IAL, and cystography was conducted approximately 10–14 days postoperatively. Chi-square test, Fisher’s exact test, Mann–Whitney U test, as well as univariable and multivariable logistic regression analyses, were used to evaluate the risk factors associated with IAL. Additionally, we analyzed the continence rate and the time to achieve continence following surgery. Results: A total of 230 patients underwent Rs-RARP for prostate adenocarcinoma performed by a single surgeon at our center during the aforementioned period. A water injection test was performed in all patients immediately after the VUA. IAL was observed in 32 patients (14%) during the water injection test. Postoperative cystography revealed very mild contrast medium leakage in only two patients (0.9%), with no impact on clinical recovery. No major IAL cases were identified on postoperative cystography. Patients with positive IAL required a significantly longer time to achieve continence compared to those without IAL (2.13 vs. 0.46 months, p = 0.008). Univariable analysis showed that a locally advanced T stage (>T2), longer console time, and absence of nerve-sparing were significantly associated with positive IAL. In multivariable analysis, a longer console time and a locally advanced T stage remained significant predictors of IAL. Conclusions: IAL detected by the water injection test was associated with the development of postoperative urinary incontinence and delayed recovery of continence. A tumor stage greater than T2 and longer console time were significant predictors of IAL. Further prospective randomized studies with larger sample sizes are required to validate our findings.

Background: Robot-assisted radical prostatectomy (RARP) is a common treatment option for prostate cancer. A 3D model for surgical guidance can improve surgical outcomes. Manual expert radiologist segmentation of the prostate and tumor in prostate MRI to create 3D models is labor-intensive and prone to inter-observer variability, highlighting the need for automated segmentation methods. Methods: This study evaluates the performance of the prostate and tumor segmentation using a commercially available AI tool without (fully automated) and with manual adjustment (AI-assisted) compared to manual segmentations on 120 patients, using several metrics, including Dice Coefficient and Hausdorff distance. Tumor detection rates were assessed with recall and precision. Results: For the prostate, both the fully automated AI model and AI-assisted model achieved a mean Dice score of 0.88, while AI-assisted had a lower Hausdorff distance (7.22 mm) compared to the fully automated (7.40 mm). For tumor segmentations, the Dice scores were 0.53 and 0.62, with Hausdorff distances of 9.53 mm and 6.62 mm obtained for fully automated AI and AI-assisted methods, respectively. The fully automated AI method had a recall of 0.74 and a precision of 0.76 in tumor detection, while the AI-assisted method achieved 0.95 recall and 0.94 precision. Fully automated segmentation required less than 1 min, while adjustments for the AI-assisted segmentation took an additional 81 s, and manual segmentation took approximately 15–30 min. Conclusions: The fully automated AI model shows promising results, offering high tumor detection rates and acceptable segmentation metrics. The AI-assisted strategy improved the relevant metrics with minimal additional time investment. Therefore, the AI-assisted segmentation method is promising for allowing 3D-model-guided surgery for all patients undergoing RARP. Full article

Background/Objectives: Obesity and abdominal adiposity are associated with worse surgical and functional outcomes in prostate cancer (PCa) patients. This exploratory study assessed whether reductions in total body fat mass (TFM) among overweight and obese PCa patients enrolled in a diet and exercise weight loss intervention prior to robotic-assisted radical prostatectomy (RARP) improved outcomes. Methods: In this secondary analysis of an NIH-funded randomized controlled trial (NCT01886677) conducted 2012–2015, twenty-nine patients with newly diagnosed, pathology-confirmed PCa who participated and underwent RARP were evaluated for percent change in TFM and divided into High Fat Losers who lost ≥1% TFM per week and Low Fat Losers who lost <1% TFM per week. High versus Low Fat Losers were compared on operative time (OT), estimated blood loss (EBL), length of hospital stay (LOS), incidence of surgical or postoperative complications, and incontinence and impotence scores at first postoperative follow-up. Results: There was a statistically significant difference between High versus Low Fat Losers with respect to overall complications (p = 0.027); 28.6% of High Fat Losers experienced one or more complications by first postoperative follow-up, compared to 73.3% of Low Fat Losers. However, no differences were observed for each individual complication analyzed, or with respect to OT, EBL, LOS, or incontinence or impotence scores. Conclusions and Relevance: Findings implicate the potential benefit of healthy weight loss as an adjunct to surgery, and support the need for larger trials to elucidate a clearer relationship between improvements in body composition and effects on specific surgical complications and functional outcomes.

Background/Objectives: HINOTORI™ is a robotic-assisted surgical platform developed in Japan. It has been applied in urologic procedures such as robot-assisted radical prostatectomy (RARP) and partial nephrectomy (RAPN). This study aimed to evaluate the clinical performance of HINOTORI™ compared with the da Vinci^® surgical system by analyzing outcomes of robot-assisted sacrocolpopexy (RSC) performed by a single skilled surgeon using a uniform surgical procedure. Methods: A total of 125 patients who underwent RSC for pelvic organ prolapse (POP) were analyzed. Surgical outcomes were compared between the HINOTORI™ (h-RSC group) and da Vinci^® (d-RSC group) platforms. Evaluated parameters included operative time, robotic console time, anterior compartment dissection time, suture time per stitch, perioperative complications, hospital stay, and POP recurrence. Results: Operative and robotic console times were significantly longer in the h-RSC group (148 vs. 139 min, p < 0.005; 109 vs. 95 min, p < 0.001). Anterior compartment dissection time showed no significant difference (p = 0.58), but suture time per stitch was longer in the h-RSC group (76 vs. 60 s, p < 0.005), possibly due to limited suture-cutting functionality, requiring manual assistance. No significant differences were observed in perioperative complications, hospital stay, and POP recurrence. Conclusions: HINOTORI™ demonstrated surgical precision and safety comparable to the da Vinci^® surgical system. It may serve as a viable alternative robotic platform, supporting broader adoption of robot-assisted surgical technologies. Full article

Emerging imaging-guided technologies, such as prostate-specific membrane antigen radioguided surgery (PSMA-RGS) and augmented reality (AR), could enhance the precision and efficacy of robot-assisted prostate cancer (PCa) surgical approaches, maximizing the surgeons’ ability to remove all cancer sites and thus patients’ outcomes. Sentinel node biopsy (SNB) represents an imaging-guided technique that could enhance nodal staging accuracy by leveraging lymphatic mapping with tracers. PSMA-RGS uses radiolabeled tracers with the aim to improve intraoperative lymph node metastases (LNMs) detection. Several studies demonstrated its feasibility and safety, with promising accuracy in nodal staging during robot-assisted radical prostatectomy (RARP) and in recurrence setting during salvage lymph node dissection (sLND) in patients who experience biochemical recurrence (BCR) after primary treatment and have positive PSMA positron emission tomography (PET). Near-infrared PSMA tracers, such as OTL78 and IS-002, have shown potential in intraoperative fluorescence-guided surgery, improving positive surgical margins (PSMs) and LNMs identification. Finally, augmented reality (AR), which integrates preoperative imaging (e.g., multiparametric magnetic resonance imaging [mpMRI] of the prostate and computed tomography [CT]) onto the surgical field, can provide a real-time visualization of anatomical structures through the creation of three-dimensional (3D) models. These technologies may assist surgeons during intraoperative procedures, thus optimizing the balance between oncological control and functional outcomes. However, challenges remain in standardizing these tools and assessing their impact on long-term PCa control. Overall, these advancements represent a paradigm shift toward personalized and precise surgical approaches, emphasizing the integration of innovative strategies to improve outcomes of PCa patients.

Background/Objectives: Inguinal hernia (IH) is a common complication after robot-assisted radical prostatectomy (RARP), significantly impacting patients’ quality of life. This study aimed to evaluate whether peritoneal closure reduces the incidence of IH after RARP. Methods: A retrospective analysis was conducted on 772 patients who underwent transperitoneal RARP between April 2018 and March 2023. Patients with a history of IH surgery were excluded. Peritoneal closure, introduced in December 2021, was performed during the final steps of RARP in 144 patients. The incidence of IH was compared between patients with and without peritoneal closure. Multivariate analysis was performed to identify significant predictors of IH. Results: IH occurred in 73 patients (9.5%)—5 (3.5%) in the peritoneal closure group and 68 (10.8%) in the no peritoneal closure group. Multivariate analysis revealed that the absence of peritoneal closure (hazard ratio [HR] = 4.55, p = 0.04) and low body mass index (BMI < 23 kg/m²; HR = 2.51, p = 0.001) were significant predictors of IH. The two-year IH-free survival rate was 96.5% in the peritoneal closure group and 89.2% in the no peritoneal closure group. Conclusions: Peritoneal closure significantly reduces the incidence of IH after RARP. This simple and effective technique may serve as a valuable preventive measure against postoperative IH, potentially improving surgical outcomes and patient quality of life. Further studies are warranted to confirm these results in diverse patient populations. Full article

Background: Despite numerous studies assessing LCs in urological surgical oncology, high-quality evidence and a fully structured curriculum are missing. We aimed to systematically search and review the available literature on the LCs of robot-assisted surgery in urological cancers. Methods: Medline was systematically searched up to December 2024 to retrieve studies following the Preferred Reporting Items reporting on LC in robot-assisted radical prostatectomy (RARP), robot-assisted radical cystectomy (RARC), robot-assisted radical and partial nephrectomy (RARN, RAPN), and robot-assisted radical nephroureterectomy (RANU). The results of the last five years were then compared to those of the previous years. Results: In total, 82 studies were identified, 47 of which were for prostatectomy, 9 of which were for the last 5 years. Eighteen studies referred to partial-nephrectomy, seven over the previous 5 years. Finally, 16 studies referred to radical cystectomy, 7 over the previous five years. For radical prostatectomy, LC was based on operative time (OT), estimated blood loss (EBL), length of hospital stays, complication rate, positive surgical margin (PSM), biochemical recurrence (BCR), continence, and potency with ranges of 100–400, 90–290, 200, 15–250, 50–300, 30–250, 200–500 and 200–300 cases, respectively. For partial nephrectomy, the LC was based on OT, EBL, length of hospital stay, complication rate, warm ischemia time (WIT), and trifecta, with unclear ranges for the first three categories and 20–50, 26–140, and 50–77 cases, respectively, for the rest. Finally, for radical cystectomy, the LC was based on OT, EBL, length of hospital stay, complication rate, PSM, and lymph node yield, with ranges 20–75, 88, 40–198, 16–100, no difference, and 30–50 cases, respectively. We could not identify any study assessing the LCs in RARN and RANU. Conclusions: Robot-assisted surgery does not have a standard definition of LC regardless of the type of operation, which causes heterogeneity between the studies. Nevertheless, LCs appear to be steep and continuous. Training curriculums are essential to optimize outcomes and prepare new surgeons. Full article

Background/Objectives: Prostate-specific antigen (PSA) persistence, defined as a postoperative PSA level ≥ 0.1 ng/mL measured within 4–8 weeks after radical prostatectomy (RP), predicts biochemical recurrence (BCR) and adverse oncological outcomes. The influence of nerve-sparing (NS) surgical techniques on PSA persistence remains debated, especially among patients with high-risk pathological features. This study aimed to evaluate the impact of NS techniques on PSA persistence following robot-assisted radical prostatectomy (RARP), considering tumor characteristics, surgical parameters, and patient-specific factors. Methods: A retrospective cohort analysis was performed on 779 patients who underwent RARP at a single institution between January 2002 and December 2015. The inclusion criteria consisted of histologically confirmed prostate cancer with available preoperative and postoperative data, including PSA measurements taken 4–8 weeks after surgery. PSA persistence served as the primary outcome. Statistical analyses included descriptive statistics, univariate and multivariable logistic regression models to identify predictors of PSA persistence, and Spearman’s correlation along with the Kruskal–Wallis H test to evaluate associations. Results: Of the 779 patients included, 55% underwent NS surgery (51% unilateral, 49% bilateral). The mean preoperative PSA was 11.85 ng/mL (SD: 7.63), while the mean postoperative PSA was 0.70 ng/mL (SD: 4.42). An elevated postoperative PSA was associated with a larger tumor size (r = 0.1285, p < 0.001), advanced pathological stages (χ² = 45.10, p = 3.79 × 10⁻⁹), and higher Gleason scores (χ² = 24.74, p = 1.57 × 10⁻⁴). NS surgery correlated with a lower postoperative PSA (mean: 0.20 ng/mL) compared to non-NS procedures (mean: 0.65 ng/mL), with slight differences between unilateral (mean: 0.30 ng/mL) and bilateral (mean: 0.35 ng/mL) NS approaches. Multivariable regression analysis identified advanced pathological stage (coefficient = 1.16, p = 0.04) as an independent predictor of PSA persistence, while NS techniques had no significant independent effect (coefficient = −0.01, p = 0.99). Conclusions: Nerve-sparing surgical techniques do not independently predict PSA persistence after RARP when adjusting for tumor-related factors and confounders. Advanced pathological stage, particularly stage pT3b, primarily determines PSA persistence. These findings highlight the necessity of personalized surgical planning informed by preoperative imaging and patient-centered decision making to optimize oncological and functional outcomes.

Background/Objectives: Adverse in-hospital outcomes at radical prostatectomy have not been specifically addressed in young patients aged 40–49 years (quadragenarians). Additionally, no comparison between robot-assisted (RARP) vs. open radical prostatectomy (ORP) has been reported in this population. Methods: Descriptive analyses, propensity score matching (PSM), and multivariable logistic/Poisson regression models addressed quadragenarians undergoing RARP or ORP within the National Inpatient Sample (2009–2019). Results: Of 5426 quadragenarians, 4083 (75.2%) and 1343 (24.8%) underwent RARP and ORP, respectively. The proportion of RARP increased from 68.1 to 84.5% (2009–2019, EAPC: +2.8%, p < 0.001). Adverse in-hospital outcomes after RARP were invariably lower than those after ORP. Specifically, the rates of overall complications (7.8 vs. 13.4%, Δ −5.6%, multivariable odds ratio (OR): 0.54), blood transfusions (1.2 vs. 6.3%, Δ −5.1%, OR: 0.21), and length of stay (LOS) > 2 days (10.6 vs. 28.7%, Δ −18.1%, OR: 0.32) were lower after RARP than after ORP (all p < 0.001). After additional one-to-one PSM between ORP and RARP patients, virtually the same results were reported (overall complications: 7.0 vs. 13.4%, Δ −6.4%, OR: 0.49; blood transfusion rates: 1.5 vs. 6.3%, Δ −4.8%, OR: 0.23; LOS > 2 days: 10.9 vs. 28.7%, Δ −17.8%, OR: 0.30). Conversely, RARP use resulted in higher total hospital charges (USD 43,690 vs. 36,840, Δ USD +6850, IRR: 1.18; p < 0.001). Conclusions: Quadragenarians exhibited a more favorable adverse in-hospital outcome profile after RARP vs. ORP. These advantages are offset by a small, albeit significant, increase in total hospital charges. Full article
