Background/Objectives: To externally validate and compare four postoperative upper tract urothelial carcinoma (UTUC) nomograms in a contemporary Australian radical nephroureterectomy (RNU) cohort, and to identify independent clinicopathological predictors of survival. Methods: We conducted a retrospective study across a multi-site tertiary service in Victoria of patients who underwent RNU for localised UTUC between January 2011 and December 2021. Patients were excluded if RNU was performed for non-UTUC-related reasons or if they had incomplete data. Univariable and multivariable Cox models assessed prognostic factors. Discrimination of the nomograms was evaluated using Harrell’s C-index with bootstrap-corrected calibration. Results: Of 142 total patients undergoing RNU, 103 were included in the final study cohort. In our multivariable Cox regression analysis, increasing age, sessile architecture and higher tumour stage emerged as independent predictive factors for worse overall survival (OS). For cancer-specific survival (CSS), increasing age, higher tumour stage, tumour location in the kidney, and synchronous tumours in the kidney and ureter were statistically significant. Four nomograms (Seisen, Abdul-Muhsin, Cha and Roupret) were identified. External validation showed the best discrimination of CSS for Seisen (C-index 0.814, 95% confidence interval (CI) 0.687–0.915); Abdul-Muhsin had good OS but moderate CSS discrimination (C-index 0.708 and 0.651), Cha showed good CSS but excellent recurrence-free survival (RFS) discrimination (C-index 0.770 and 0.826) and Roupret CSS nomogram showed good CSS discrimination (C-index 0.789, 95% CI (0.653, 0.900). Conclusions: The Seisen nomogram provided the most accurate, well-calibrated five-year cancer-specific predictions after RNU, outperforming the Abdul-Muhsin, Cha and the Roupret models, likely due to its weighting of age, location, and sessile architecture, which are independent predictors of worse CSS. These data endorse a risk-adapted strategy using the Seisen nomogram to guide postoperative counselling, surveillance intensity, and consideration for adjuvant therapy. Full article

Background/Objectives: Prostate biopsy is essential for diagnosing prostate cancer. Social determinants of health (SDOH), including socioeconomic status, race, occupation, education, and environment, affect access, outcomes, and quality of life. Recognizing disparities from technology access to complications is crucial for equitable care. A systematic review examined how SDOH impacts biopsy access, technology, and complications. Methods: A systematic search of PubMed, Web of Science, and Scopus was performed to identify eligible studies published through February 2026. We included studies that evaluated the association between one or more SDOHs and prostate biopsy. Relevant outcomes included biopsy utilization, use of specific biopsy technologies (e.g., magnetic resonance imaging (MRI)-guided, transperineal), and post-procedural complications. Results: Nine observational studies met the inclusion criteria. The findings revealed disparities across three key domains. First, access to advanced biopsy technology was uneven. Four studies showed that Black men were significantly less likely than White men to receive MRI-guided biopsies. Additionally, post-biopsy outcomes showed that Black and Hispanic men faced significantly higher rates of post-biopsy infection and hospitalization compared to White men. Lastly, patients in rural areas, those in public hospitals, and individuals with lower socioeconomic status demonstrated reduced access to modern techniques, including MRI-guided or transperineal biopsy. Conclusions: Social and economic factors influence who receives a prostate biopsy and who has access to advanced technologies. Minority and low-income patients face diagnosis barriers and higher complication rates, highlighting systemic inequities. The healthcare system often rewards access over need, and without bold policy changes, gaps in technology and resources will worsen, moving us further from truly equitable prostate cancer care.

Background/Objectives: Variations in urinary symptom improvement after benign prostatic hyperplasia (BPH) surgery remain incompletely characterized. Preoperative factors, including bowel dysfunction, may influence postoperative recovery. We evaluated the association between baseline bowel function and urinary outcomes after holmium laser enucleation of the prostate (HoLEP), hypothesizing that worse baseline constipation would be associated with poorer outcomes. Methods: A prospective cohort study of patients undergoing HoLEP by a single surgeon at a high-volume center (December 2023–September 2024) was performed. Patients with neurogenic bladders, bowel disorders, or diabetes mellitus were excluded. Baseline bowel function was assessed using the Constipation Scoring System (CSS) and Vaizey Incontinence Score (VIS). The primary outcomes were 3-month changes in International Prostate Symptom Score (IPSS) and Michigan Incontinence Severity Index (MISI). Associations were evaluated using Spearman correlation and multivariable linear regression. Results: Among 102 patients (median age of 71.6 years), 81 (79.4%) completed follow-up. The median prostate size was 90.5 cc, and 50% had prior urinary retention. The baseline CSS and VIS were low. IPSS, quality of life, and MISI bother improved postoperatively, while MISI severity showed minimal change. Higher CSS correlated with higher VIS (p < 0.001). Baseline CSS and VIS were not associated with changes in IPSS, quality-of-life (QoL), or MISI bother. Baseline VIS was associated with modest improvement in MISI severity (β −1.14, p = 0.01). Conclusions: Baseline bowel function was not associated with urinary symptom improvement after HoLEP. However, preoperative fecal incontinence was associated with improvement in urinary incontinence severity. Full article

Background/Objectives: Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive intervention for overactive bladder (OAB) typically utilized in patients for whom behavioural and pharmacological therapies do not work. The aim of this study is to identify predictors of progression to alternate minimally invasive treatment options following PTNS in patients with OAB refractory to medical and behavioural therapy. In addition, the aim of this study is to determine predictors of maintenance therapy after completing PTNS induction. Methods: This study is a retrospective cohort analysis of patients that underwent PTNS between March 2018 and June 2023 for management of overactive bladder. The primary outcome of this study is progression to alternate minimally invasive treatment options following PTNS, such as sacral neuromodulation or intradetrusor onabotulinum toxin injections. The secondary outcome of this study is the continuation of maintenance therapy following the initial 12-week PTNS treatment course. Results: A total of 49 patients were included for analysis. Overall, 33% (16/49) of patients had further alternate minimally invasive treatment. Multivariate logistic regression analysis identified only age (odds ratio (OR) = 1.06; p = 0.05) as a significant predictor of progression to alternate minimally invasive OAB treatment following PTNS. Overall, 27 (55%) patients continued with ongoing monthly maintenance PTNS after completing initial weekly treatment for OAB. Multivariate logistic regression only identified sex as a predictor of ongoing maintenance PTNS (OR = 13.2; p = 0.017). Conclusions: The present study identifies younger age as a significant predictor of progression to further minimally invasive OAB treatments after PTNS. Furthermore, female sex was found to be a significant predictor of ongoing maintenance PTNS. Full article

Background/Objectives: Contemporary minimally invasive surgical therapies (MISTs) for benign prostatic hyperplasia carry retreatment rates up to 32%, with holmium laser enucleation of the prostate (HoLEP) increasingly used as salvage therapy. Prior reviews focused on salvage HoLEP (sHoLEP) following transurethral resection; however, technical challenges specific to the post-MIST field remain uncharacterised. We aimed to characterise technical barriers during sHoLEP following contemporary MISTs, with secondary evaluation of efficacy, safety and feasibility. Methods: Following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines (PROSPERO: CRD420261321711), five databases were searched from inception to February 2026. Studies reporting sHoLEP outcomes in adults with prior MIST were included. Qualitative findings were synthesised thematically; quantitative outcomes reported by three or more studies underwent random-effects meta-analysis. Risk of bias was assessed using methodological index for non-randomized studies methodological index for non-randomized studies (MINORS) and certainty of evidence using grading of recommendations, assessment, development, and evaluation (GRADE). Results: Ten studies (354 sHoLEP, 3618 primary HoLEP (pHoLEP) patients) were included. Technical difficulty was MIST-type dependent: thermoablative procedures and prostatic artery embolisation preserved the enucleation plane, while prostatic urethral lift (PUL) introduced morcellation-specific challenges including blade jamming and staged procedures. Meta-analysis revealed no difference in operative time or tissue weight, but reduced enucleation efficiency (weighted mean difference; WMD −0.11 g/min, p = 0.027) and peak urinary flow improvement (WMD −3.0 mL/s, p < 0.001). Both findings were sensitive to analysis, losing significance on restriction to predominantly MIST cohorts, and the enucleation efficiency result additionally lost significance on removal of the most heavily weighted study (p = 0.94). Complication rates were equivalent (odds ratio (OR) 0.92, p = 0.787). Conclusions: sHoLEP is safe and efficacious following contemporary MIST. Surgeons should anticipate MIST-specific challenges, particularly morcellation difficulties after PUL requiring tailored instrumentation. Prospective MIST-specific studies are needed. Full article

Background/Objectives: To evaluate the feasibility, in-hospital mortality, and perioperative morbidity of open radical cystectomy performed entirely under combined spinal-thoracic epidural anesthesia (CSTEA) in patients with a predominantly high anesthetic risk profile. Methods: This retrospective multicenter cohort study included 145 consecutive adults with histologically confirmed bladder cancer who underwent open radical cystectomy with pelvic lymph node dissection and urinary diversion under planned CSTEA at two institutions between 2008 and 2017. The rationale for CSTEA was to preserve spontaneous breathing and avoid planned intubation and neuromuscular blockade in selected patients. The primary endpoint was in-hospital mortality during the index admission. Results: Most patients were classified as American Society of Anesthesiologists (ASA) III (85.5%) or ASA IV (1.4%). Urinary diversion consisted of transureteroureterocutaneostomy in 97 patients (66.9%), ileal conduit in 24 (16.6%), and orthotopic ileal neobladder in 24 (16.6%). No patient required intraoperative conversion to general anesthesia. In-hospital mortality was 0.7% (1/145), and severe complications occurred in 5.5%. Median length of stay was 15 days, and median postoperative pain score was 1. Conclusions: Open radical cystectomy under CSTEA appeared feasible in selected patients and was associated with low in-hospital mortality, low severe complication rates, and favorable early recovery. These findings support CSTEA as a feasibility-based option in experienced centers, while prospective comparative studies using standardized in-hospital, 30-day, and 90-day endpoints are needed.

Background/Objectives: Recently the European Association of Urology (EAU) guidelines presented the EAU Guidelines bot to assist urologists in the reading of the guidelines; however, there is a lack of up-to-date external validation. The aim of our study is to assess the accuracy, completeness, and clarity of the guidelines bot in urethral strictures. Methods: A total of 117 questions based on the EAU urethral strictures guidelines recommendations were developed. Each question was input to the EAU guidelines bot and the response was assessed by two expert urologists to assess the accuracy, completeness, and clarity. Moreover, 10 simple clinical cases were input. A 5-point Likert scale was used as a score and, in case of discrepancies, a third urologist was queried. Accuracy, completeness and clarity were assessed per chapter and per grade of recommendation. All questions and answers were recorded in an Excel file. Results: Overall 117 questions were developed. In terms of accuracy, 111/117 (95%) were defined as accurate (scores 4–5), 4/117 (3%) presented a fair accuracy (score 3), and 2/117 (2%) were deemed not accurate. In terms of completeness, 93/117 (80%) were defined as complete (scores 4–5), 22/117 (19%) presented a fair completeness (score 3), and 2/117 (2%) were deemed not complete. Finally, in terms of clarity, 104/117 (89%) were defined as clear (scores 4–5), 13/117 (11%) presented a fair clarity (score 3), and 0/109 (0%) were deemed not clear. When comparing strong and weak recommendations, no differences were recorded. Overall the answers to simple clinical cases were in line with the guidelines with good accuracy, completeness and clarity scores. Conclusions: The EAU guidelines bot represents an accurate tool for urethral stenosis guidelines. Some fine-tuning is needed to improve readability and clarity. Full article
