Since its development in 1904, radical prostatectomy (RP) has remained a fundamental surgical option in the management of localised prostate cancer. Over time, continuous advancements in surgical techniques have improved oncological outcomes while reducing functional complications. This narrative review explores the evolution of RP, depicting its progression from the traditional open approach to minimally invasive laparoscopic and robotic-assisted techniques. Key developments in RP techniques, including nerve-sparing, bladder neck-sparing and Retzius-sparing techniques as well as enhanced perioperative management, have contributed to reduced postoperative complications, namely incontinence and erectile dysfunction. Additionally, technological innovations such as augmented reality, utilising indocyanine green for improved visualisation of prostatic boundaries and illuminare-1 to easily identify nerves intraoperatively, artificial intelligence, and novel molecular imaging technologies such as PSMA PETs for improved margin assessment are shaping the future of RPs. Despite these advancements, challenges persist, including a steep learning curve associated with newer techniques, disparities in access due to cost considerations, and a lack of standardised outcome measures across different surgical approaches. This review provides insight into current trends, ongoing challenges, and future directions that may further refine surgical precision, enhance patient safety, and improve long-term treatment success in prostate cancer management.

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

Prostate cancer is one of the most commonly diagnosed malignancies worldwide and is a major cause of cancer-associated morbidity in men. Radical prostatectomy (RP) is a cornerstone of intervention for organ-confined diseases and offers a potentially curative outcome. In recent decades, RP has undergone transformative changes, moving from open surgery, with significant morbidity, to minimally invasive and robot-assisted techniques. These advances have improved surgical precision, reduced blood loss, and accelerated functional recovery. Key enhancements, such as the “Veil of Aphrodite”, hood-sparing, and Retzius-sparing approaches, aim to preserve neurovascular structures vital for continence and sexual function, addressing the persistent challenge of balancing oncological control with quality-of-life outcomes. Single-port (SP) robotic platforms represent the latest frontier, offering various access routes, including extraperitoneal, transvesical, transperitoneal, and transperineal routes, to further reduce incisional morbidity. Early experiences with SP robot-assisted radical prostatectomy(RARP) suggest favorable continence rates and short hospital stays, although concerns remain regarding the technical complexity and potential margin status of the advanced disease. Comparisons across these techniques revealed broadly similar long-term oncological outcomes, underscoring the importance of patient selection, tumor staging, and surgeon expertise. Ongoing innovations in robotic systems, augmented imaging modalities, and personalized surgical planning are likely to refine prostate cancer care and enhance both survival and post-treatment quality of life.

Background/Objectives: The prognostic value of baseline clinical parameters in predicting the survival prolonging effect of Radium-223-dichloride (²²³RaCl₂) for metastatic castration resistant prostate cancer (mCRPC) patients has been the object of intensive research and remains an open issue. This national multicenter study aimed to corroborate the evidence of ten years of clinical experience with ²²³RaCl₂ by collecting data from eight Italian Nuclear Medicine Units. Methods: Data from 581 consecutive mCRPC patients treated with ²²³RaCl₂ were retrospectively analyzed. Several baseline variables relevant to the overall survival (OS) analysis were considered, including age, previous radical prostatectomy/radiotherapy, number of previous treatment lines, prior chemotherapy, Gleason score, presence of lymphoadenopaties, number of bone metastases, concomitant use of bisphosphonates/Denosumab, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), as well as baseline values of hemoglobin (Hb), platelets, Total Alkaline Phosphatase (tALP), Lactate Dehydrogenase (LDH), and Prostate-Specific Antigen (PSA). Data were summarized using descriptive statistics, univariate analysis and multivariate analysis with the Cox model. Results: The median OS time was 14 months (95%CI 12–17 months). At univariate analysis age, the number of previous treatment lines, number of bone metastases, ECOG-PS, presence of lymphadenopathies at the time of enrollment, as well as baseline tALP, PSA, and Hb, were independently associated with OS. After multivariate analysis, the number of previous treatment lines (HR = 1.1670, CI = 1.0095–1.3491, p = 0.0368), the prior chemotherapy (HR = 0.6461, CI = 0.4372–0.9549, p = 0.0284), the presence of lymphadenopathies (HR = 1.5083, CI = 1.1210–2.0296, p = 0.0066), the number of bone metastases (HR = 0.6990, CI = 0.5416–0.9020, p = 0.0059), ECOG-PS (HR = 1.3551, CI = 1.1238–1.6339, p = 0.0015), and baseline values of tALP (HR = 1.0008, CI = 1.0003–1.0013, p = 0.0016) and PSA (HR = 1.0004, CI = 1.0002–1.0006, p = 0.0005) remained statistically significant. Conclusions: In the era of precision medicine and in the landscape of novel therapies for mCRPC, the prognostic stratification of patients undergoing ²²³RaCl₂ has a fundamental role for clinical decision-making, ranging from treatment choice to optimal sequencing and potential associations. This large Italian multicenter study corroborated the prognostic value of several variables, emerging from ten years of clinical experience with ²²³RaCl₂. Full article

Background/Objectives: Robot-assisted and open radical prostatectomy (RARP and ORP) are established procedures for localized prostate cancer, with comparable oncological and functional outcomes. Little is known about patients’ knowledge of both procedures. This study aimed to examine comparatively the informational behaviour and knowledge of patients undergoing ORP vs. RARP. Methods: This prospective, multicentre study included patients who underwent RARP or ORP prior to presurgery counselling. The questionnaires gathered information about patients’ information-seeking behaviours and their assessment of outcomes for RARP vs. ORP. We investigated risk factors for the misperception of procedure outcomes. Results: A total of 508 patients were included (307 RARP (60%); 201 ORP (40%)). The most common sources of information were outpatient urologists (84%), urologic departments (67%) and the internet (57%). Compared with ORP, RARP patients more often received the same amount of information about both procedures (60% vs. 40%, p < 0.001). Compared with ORP, RARP patients wrongfully considered their procedure to be superior in terms of oncological and functional outcomes. In the multivariable analysis, age > 66 years (OR 2.1, p = 0.02), no high school degree (OR 1.9, p = 0.04), unbalanced information search (OR 2.4, p = 0.02), RARP patient status (OR 8.9, p < 0.001), and treatment at a centre offering only one procedure (OR 3.5, p < 0.001) were independent predictors of misperception. Conclusions: RARP patients wrongfully considered their intervention to be oncologically and functionally more beneficial than ORP patients perceived it to be. This may be due to unbalanced sources of information. Urologists and surgical centres must address this misperception to enable patients to make informed decisions. Full article

Background and Objectives: We conducted a systematic review and network meta-analysis to evaluate and compare the perioperative, functional, and oncological outcomes of robot-assisted radical prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP) with open radical prostatectomy (ORP) in patients with prostate cancer. Materials and Methods: A comprehensive literature search was performed in Pubmed, EMBASE, and the Cochrane library for papers published before May 2021. Only studies of patients with prostate cancer that assessed perioperative, functional, and oncological outcomes and reported outcome values were included. We used a Bayesian hierarchical random-effects model to synthesize data from multiple studies, enabling both direct and indirect comparisons of the three surgical approaches (RARP, LRP, ORP) to provide robust estimates of their relative efficacy. This systematic review was registered in PROSPERO (CRD42021282555). Results: A total of 80 studies were finally included in the present study. Biochemical recurrence (BCR) rates were lower for RARP than for ORP (RR 0.713, 95% CrI 0.587–0.869) and LRP (RR 0.672, 95% CrI 0.505–0.895). Compared with ORP, RARP had a significantly lower positive surgical margin (RR 0.893, 95% CrI 0.807–0.985). When compared to ORP, RARP and LRP showed no significant difference in continence (RR 1.057, 95% CrI 0.997–1.124; RR 0.921, 95% CrI 0.845–1.007). When compared to ORP, RARP was significantly more effective on potency (RR 1.201, 95% CrI 1.047–1.402). The potency rate was significantly higher for RARP than for ORP (RR 1.201, 95% CrI 1.047–1.402) and LRP (RR 1.438, 95% CrI 1.191–1.762). There was no difference in the estimated blood loss or the total and major complication rates between RARP, ORP, and LRP. The operation time was longest for LRP. There was no difference in the operation time between RARP and ORP. Conclusions: RARP may be better or comparable to ORP and LRP in terms of oncologic outcomes (PSM and BCR), functional outcomes (potency and incontinence), and perioperative outcomes (EBL, operation time, and total and major complications).

Background and Objectives: Radical prostatectomy (RP) stands as the predominant instigator of postoperative stress urinary incontinence. Techniques such as the preservation of the neurovascular bundles, bladder neck preservation, and ensuring longer postoperative urethral length have shown positive impacts on continence. The posterior reconstruction is another method that aids in early continence recovery. Anterior suspension as simulator of puboprostatic ligaments is another factor. Materials and Methods: This study was conducted in the Clinic of Urology, University Clinical Center of Serbia, between December 2014 and January 2020, employing a prospective, non-randomized comparative design. Data were meticulously gathered from 192 consecutive patients. The process of regaining continence was monitored at intervals of 1, 3, 6, 12, and 24 months after surgery. The main criterion for assessing the level of urinary continence was the number of pads used daily. Results: The distribution of overall continence rates in the BNP vs. no-BNP group at 3, 6 and 12 months was 86% vs. 60% (p < 0.0001), 89% vs. 67% (p < 0.0001), 93% vs. 83% (p = 0.022). Continence rates in non-posterior reconstruction group (10%, 22%, 34%, and 54% at 1, 3, 6, and 12 months) were statistically significantly lower (p < 0.0001). The patients who underwent urethral suspension exhibited significantly higher rates of overall continence at 1 mo (73% vs. 29%, p < 0.0001), 3 mo (85% vs. 53%, p < 0.001), 6 mo (89% vs. 62%, p < 0.0001), 12 mo (95% vs. 76%, p < 0.0001), and 24 mo (93% vs. 81%, p = 0.007). Patients who underwent urethral suspension had a four-fold greater likelihood of regaining continence (p = 0.015). Conclusions: Patients who underwent urethral suspension or BNP or posterior reconstruction had higher continence rates. Only the urethral suspension was found to be a significant prognostic factor of continence recovery. Full article

PURPOSE: We aim to compare the performance of three different radiomics models (logistic regression (LR), random forest (RF), and support vector machine (SVM)) and clinical nomograms (Briganti, MSKCC, Yale, and Roach) for predicting lymph node involvement (LNI) in prostate cancer (PCa) patients. MATERIALS AND METHODS: The retrospective study includes 95 patients who underwent mp-MRI and radical prostatectomy for PCa with pelvic lymphadenectomy. Imaging data (intensity in T2, DWI, ADC, and PIRADS), clinical data (age and pre-MRI PSA), histological data (Gleason score, TNM staging, histological type, capsule invasion, seminal vesicle invasion, and neurovascular bundle involvement), and clinical nomograms (Yale, Roach, MSKCC, and Briganti) were collected for each patient. Manual segmentation of the index lesions was performed for each patient using an open-source program (3D SLICER). Radiomic features were extracted for each segmentation using the Pyradiomics library for each sequence (T2, DWI, and ADC). The features were then selected and used to train and test three different radiomics models (LR, RF, and SVM) independently using ChatGPT software (v 4o). The coefficient value of each feature was calculated (significant value for coefficient ≥ ±0.5). The predictive performance of the radiomics models and clinical nomograms was assessed using accuracy and area under the curve (AUC) (significant value for p ≤ 0.05). Thus, the diagnostic accuracy between the radiomics and clinical models were compared. RESULTS: This study identified 343 features per patient (330 radiomics features and 13 clinical features). The most significant features were T2_nodulofirstordervariance and T2_nodulofirstorderkurtosis. The highest predictive performance was achieved by the RF model with DWI (accuracy 86%, AUC 0.89) and ADC (accuracy 89%, AUC 0.67). Clinical nomograms demonstrated satisfactory but lower predictive performance compared to the RF model in the DWI sequences. CONCLUSIONS: Among the prediction models developed using integrated data (radiomics and semantics), RF shows slightly higher diagnostic accuracy in terms of AUC compared to clinical nomograms in PCa lymph node involvement prediction.

In addition to general anesthesia and mechanical ventilation, robotic-assisted laparoscopic radical prostatectomy (RALP) necessitates maintaining a capnoperitoneum and placing the patient in a pronounced downward tilt (Trendelenburg position). While the effects of the resulting fluid shift on the cardiovascular system seem to be modest and well tolerated, the effects on the brain and the blood–brain barrier have not been thoroughly investigated. Previous studies indicated that select patients showed an increase in the optic nerve sheath diameter (ONSD), detected by ultrasound during RALP, which suggests an elevation in intracranial pressure. We hypothesize that the intraoperative fluid shift results in endothelial dysfunction and reduced cerebral clearance, potentially leading to transient neuronal damage. This prospective, monocentric, non-randomized, controlled clinical trial will compare RALP to conventional open radical prostatectomy (control group) in a total of 50 subjects. The primary endpoint will be the perioperative concentration of neurofilament light chain (NfL) in blood using single-molecule array (SiMoA) as a measure for neuronal damage. As secondary endpoints, various other markers for endothelial function, inflammation, and neuronal damage as well as the ONSD will be assessed. Perioperative stress will be evaluated by questionnaires and stress hormone levels in saliva samples. Furthermore, the subjects will participate in functional tests to evaluate neurocognitive function. Each subject will be followed up until discharge. Conclusion: This trial aims to expand current knowledge as well as to develop strategies for improved monitoring and higher safety of patients undergoing RALP. The trial was registered with the German Clinical Trials Register DRKS00031041 on 11 January 2023. Full article

Background: We developed a novel surgical technique: dissection of the retrotrigonal layer from a posterior approach in robot-assisted radical prostatectomy (RARP). This approach enables earlier access to the posterior space during bladder neck dissection and helps preserve the bladder neck. We evaluated the safety and efficacy of this technique in terms of bladder neck preservation Methods: We retrospectively reviewed 238 consecutive patients who underwent RARP using this technique from August 2021 to September 2023. Key metrics included the success rate of accessing the posterior space prior to bladder neck opening during the dissection and the rate of bladder neck preservation. In addition, oncological and surgical safety, as well as continence recovery, were assessed. Results: The median age and prostate-specific antigen level were 72 (65–75) years and 7.35 (5.40–11.5) ng/mL, respectively. In 153 (64%) patients, the posterior space was successfully accessed before bladder neck opening, with the success rate increasing from 56% in the series’ first half to 72% in the second half (p = 0.015). The bladder neck was preserved in 120 (53%) patients, and this rate increased from 39% in the first half to 63% in the second half (p = 0.0004). Positive surgical margins at the junction between the prostate and bladder were observed in 10 cases (4%). Bladder neck preservation correlated with early continence recovery (hazard ratio 1.37 [95% confidence interval 1.03–1.83], p = 0.030). The grade 3 complication associated with this technique occurred in one case (0.5%). Conclusion: Retrotrigonal layer dissection from a posterior approach in RARP enhances the safety and ease of bladder neck dissection and aids in its preservation, potentially leading to improved continence recovery.

Introduction: Radical prostatectomy is increasingly performed laparoscopically with robot assistance (RALRP). RALRP, as with all laparoscopic procedures, requires a pneumoperitoneum, which might result in peritoneal inflammatory response reactions and postoperative pain. The aim of this retrospective single-centre study was to analyse the effects of a pneumoperitoneum during RARLP on clinical outcomes. Methods: All patients who underwent robot-guided prostatectomy in our clinic were included, with the exception of patients who were converted to open prostatectomy. C-reactive protein was used as a marker for the primary outcome, namely the postoperative inflammatory response. Intra-abdominal pressure (IAP) was evaluated as a potential factor influencing inflammation. In addition, the waist–hip ratio was used to estimate the amount of visceral adipose tissue, and the administration of dexamethasone was considered as a factor influencing inflammation. The Visual Analogue Scale (VAS) was used to determine postoperative pain. Patients were consecutively recruited between 1 September 2020 and 31 March 2022. Results: A total of 135 consecutive patients were included. The median waist–hip ratio was 0.55. The median duration of the pneumoperitoneum was 143 min. The median values of the average and maximum IAP values were 10 mmHg and 15 mmHg, respectively. The mean CRP of the first postoperative day was 6.2 mg/dL. The median VAS pain level decreased from 2 to 1 from the first to the third postoperative day. On the first postoperative day, 16 patients complained of shoulder pain. In addition, 134 patients were given some form of opioid pain treatment following surgery. Conclusion: We could not identify any relevant associations between the duration and IAP of the pneumoperitoneum and the indirect markers of inflammation or indicators of pain, or between the latter and the amount of visceral adipose tissue. In addition, we found no significant effect of the administration of dexamethasone on postoperative inflammation. The results point to a noninferior tolerability of moderate pressure during the procedure compared to the commonly utilised higher pressure, yet this must be confirmed in randomised controlled trials.

Nerve sparing (NS) is a surgical technique to optimize functional outcomes of radical prostatectomy (RP). However, it is not recommended in high risk (HR) cases because of the risk of a positive surgical margin that may increase the risk of cancer recurrence. In the last two decades there has been a change of perspective to the effect that in well-selected cases NS could be an oncologically safe option with better functional outcomes. Therefore, we aim to compare the functional outcomes and oncological safety of NS during RP in men with HR disease. A total of 1340 patients were included in this analysis, of which 12% (n = 158) underwent non-NSRP and 39% (n = 516) and 50% (n = 666) uni- and bilateral NSRP, respectively. We calculated a propensity score and used inverse probability of treatment weighting (IPTW) to balance the baseline characteristics of Pca patients undergoing non-NSRP and those having uni- and bilateral NSRP, respectively. NS improved functional outcomes; after IPTW, only 3% of patients having non-NSRP reached complete erectile function recovery (without erectile aid) at 24 months, whereas 22% reached erectile function recovery (with erectile aid), while 87% were continent. Unilateral NS increased the probability of functional recovery in all outcomes (OR 1.1 or 1.2, respectively), bilateral NS slightly more so (OR 1.1 to 1.4). NSRP did not impact the risk of any recurrence (HR 0.99, 95%CI 0.73–1.34, p = 0.09), and there was no difference in survival for men who underwent NSRP (HR 0.65, 95%CI 0.39–1.08). There was no difference in cancer-specific survival (0.56, 95%CI 0.29–1.11). Our study found that NSRP significantly improved functional outcomes and can be safely performed in carefully selected patients with HR-PCa without compromising long term oncological outcomes.

The aim of this study was to systematically review the current evidence regarding the oncological and functional outcomes of salvage radical prostatectomy (sRP) for recurrent prostate cancer. A systematic review was conducted throughout September 2022 using the PubMed, Science Direct, Scopus, and Embase databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. A total of 55 studies (3836 patients) met our eligibility criteria. The vast majority of men included had radiation therapy (including brachytherapy) as their first-line treatment (n = 3240, 84%). Other first-line treatments included HIFU (n = 338, 9%), electroporation (n = 59, 2%), proton beam therapy (n = 54, 1.5%), cryotherapy (n = 34, 1%), focal vascular targeted photodynamic therapy (n = 22, 0.6%), and transurethral ultrasound ablation (n = 19, 0.5%). Median preoperative PSA, at the time of recurrence, ranged from 1.5 to 14.4 ng/mL. The surgical approach was open in 2300 (60%) cases, robotic in 1465 (38%) cases, and laparoscopic in 71 (2%) cases. Since 2019, there has been a clear increase in robotic versus conventional surgery (1245 versus 525 cases, respectively). The median operative time and blood loss ranged from 80 to 297 min and 75 to 914 mL, respectively. Concomitant lymph node dissection was performed in 2587 cases (79%). The overall complication rate was 34%, with a majority of Clavien grade I or II complications. Clavien ≥ 3 complications ranged from 0 to 64%. Positive surgical margins were noted in 792 cases (32%). The median follow-up ranged from 4.6 to 94 months. Biochemical recurrence after sRP ranged from 8% to 51.5% at 12 months, from 0% to 66% at 22 months, and from 48% to 59% at 60 months. The specific and overall survival rates ranged from 13.4 to 98% and 62 to 100% at 5 years, respectively. Urinary continence was maintained in 52.1% of cases. sRP demonstrated acceptable oncological outcomes. These results, after sRP, are influenced by several factors, and above all by pre-treatment assessment, including imaging, with the development of mpMRI and metabolic imaging. Our results demonstrated that SRP can be considered a suitable treatment option for selected patients, but the level of evidence remains low. Full article

Robot-assisted surgical systems (RASS) have revolutionised the management of many urological conditions over the last two decades with robot-assisted radical prostatectomy (RARP) now being considered by many to be the preferred surgical approach. Intuitive Surgical has dominated the market during this time period with successive iterations of the da Vinci model. The expiration of patents has opened the RASS market and several new contenders have become available or are currently in development. This comprehensive narrative review aims to explore the merits of each robotic system as well as the evidence and barriers to their use. The newly developed RASS have increased the versality of robotic surgical systems to a wider range of settings through advancement in technology. The increased competition may result in an overall reduction in cost, broadening the accessibility of RASS. Learning curves and training remain a barrier to their use, but the situation appears to be improving through dedicated training programmes. Outcomes for RARP have been well investigated and tend to support improved early functional outcomes. Overall, the rapid developments in the field of robot-assisted surgery indicate the beginning of a promising new era to further enhance urological surgery. Full article

Background: The retzius-sparing approach for robotic-assisted radical prostatectomy (RARP) has been increasingly adopted. Symptomatic lymphoceles are a widespread complication of RARP with pelvic lymph node dissection. Here, we present a new technique, the peritoneal purse-string suture (PPSS), that seems to reduce the rate of symptomatic lymphoceles following retzius-sparing RARP with extended pelvic lymph node dissection (ePLND). Methods: The radical prostatectomy and bilateral lymphadenectomy are performed through three separate peritoneal openings. The PPSS uses a single suture in a way similar to a purse-string suture; the openings of both lymphadenectomy fields are widened, and the rectovesical opening from the prostatectomy is simultaneously closed. This report retrospectively evaluates the perioperative and postoperative outcomes of two consecutive patient cohorts undergoing RARP with ePLND by a single surgeon between May 2015 and June 2019, one cohort prior to introducing PPSS as control (n = 145) and the other after introducing PPSS (n = 91). Results: The two study groups were comparable on baseline characteristics, except ASA. There were no Clavien–Dindo grade IV-V complications, and comparable rates of grade I-III complications. The difference in postoperative lymphocele formation was 22% in PPSS versus 27% in the control group (p = 0.33). The rate of symptomatic lymphoceles was significantly lower in the PPSS group (3% vs. 10%, p = 0.047). Conclusion: The PPSS is a feasible procedure that reduces symptomatic lymphoceles in patients undergoing RARP with a retzius-sparing approach. Full article
