The authors found that the learning curve for robotassisted radical cystectomy is constantly evolving to improve oncologic outcomes

Preservation of endopelvic fascia, puboprostatic ligaments, dorsal venous complex and hydrodissection of the neurovascular bundles during robot-assisted radical prostatectomy: a video demonstration and propensity score matched outcomes

Introduction: We sought to report the oncologic and functional outcomes of endopelvic fascia (EPF), puboprostatic ligaments (PPL), and dorsal venous complex (DVC) preservation with hydrodissection of the neurovascular bundles (NVB) during robot-assisted radical prostatectomy (RARP). Materials and Methods: A retrospective review of our prospectively maintained prostate cancer database was performed. Patients who underwent bilateral or unilateral nerve sparing were identified. Propensity score matching was performed in a ratio of 1:1.6 between new technique (Group 1) and a historical group (Group 2). Data were reviewed for perioperative, oncologic, and functional outcomes. Cumulative incidence curves were used to depict perfect continence (0 pads), social continence (0-1 pads), and potency (SHIM≥17 with or without erectile aids). Multivariate models were used to elicit variables associated with continence and potency. Results: 76 patients in Group 1 and 126 patients in Group 2 were included. Median follow up was 17 months. Group 1 showed higher perfect continence rates at 1 month (9% vs 3%), 3 months (24% vs 19%), and 6 months (54% vs 34%) compared to Group 2 respectively (log rank p\u3c0.01). Group 1 also showed higher social continence rates at 1 month (15% vs 3%), 3 months (77% vs 32%), and 6 months (87% vs 53%) compared to Group 2 respectively (log rank p\u3c0.01). Group 1 had a similar potency rate compared to Group 2 (log rank p=0.25). Multivariate analysis showed that Group 1 was associated with improved perfect (Possibility ratio (PR) 1.82, 95% CI 1.29–2.58, p\u3c0.01) and social continence (PR 2.54, 95% CI 1.83 – 3.52, p\u3c0.01), but not potency. Conclusions: EPF, PPL, and DVC preservation with hydrodissection of the NVB offered similar oncological outcomes, but earlier and improved urinary continence rates compared to standard dissection

Robot-assisted Radical Cystectomy Versus Open Radical Cystectomy: A Systematic Review and Meta-analysis of Perioperative, Oncological, and Quality of Life Outcomes Using Randomized Controlled Trials

The primary outcome was the rate of 90-d perioperative events. The secondary outcomes included operative, pathological, survival, and health-related QoL (HRQoL) measures.  Evidence acquisition: Systematic literature searches of MEDLINE, Embase, Web of Science, and clinicaltrials.gov were performed up to May 31, 2022.  Evidence synthesis: Eight trials, reporting 1024 participants, were included. RARC was associated with a shorter hospital length of stay (LOS; mean difference [MD] 0.21, 95% confidence interval [CI] 0.03–0.39, p = 0.02) than and similar complication rates to ORC. ORC was associated with higher thromboembolic events (odds ratio [OR] 1.84, 95% CI 1.02–3.31, p = 0.04). ORC was associated with more blood loss (MD 322 ml, 95% CI 193–450, p < 0.001) and transfusions (OR 2.35, 95% CI 1.65–3.36, p < 0.001), but shorter operative time (MD 76 min, 95% CI 39–112, p < 0.001) than RARC. No differences in lymph node yield (MD 1.07, 95% CI –1.73 to 3.86, p = 0.5) or positive surgical margin rates (OR 0.95, 95% CI 0.54–1.67, p = 0.9) were present. RARC was associated with better physical functioning or well-being (standardized MD 0.47, 95% CI 0.29–0.65, p < 0.001) and role functioning (MD 8.8, 95% CI 2.4–15.1, p = 0.007), but no improvement in overall HRQoL. No differences in progression-free survival or overall survival were seen. Limitations may include a lack of generalization given trial patients.  Conclusions: RARC offers various perioperative benefits over ORC. It may be more suitable in patients wishing to avoid blood transfusion, those wanting a shorter LOS, or those at a high risk of thromboembolic events.  Patient summary: This study compares robot-assisted keyhole surgery with open surgery for bladder cancer. The robot-assisted approach offered less blood loss, shorter hospital stays, and fewer blood clots. No other differences were seen.Peer reviewe

The association between calcium channel blocker use and prostate cancer outcome

Epidemiological studies indicate that calcium channel blocker (CCB) use is inversely related to prostate cancer (PCa) incidence. The association between CCB use and PCa aggressiveness at the time of radical prostatectomy (RP) and outcome after RP was examined
