Urinary Leakage after Robot-Assisted Radical Prostatectomy: Is Always Predictive of Functional Results?

Area of Science:

• Urology
• Surgical Oncology
• Robotic Surgery

Background:

• Robotic radical prostatectomy (RARP) is a standard treatment for localized prostate cancer.
• Post-operative urinary leakage at the vesico-urethral anastomosis is a potential concern.
• The impact of such leakage on urethral stricture formation and continence recovery requires evaluation.

Purpose of the Study:

• To assess the incidence and impact of radiological urinary leakage after RARP.
• To determine if urinary leakage affects urethral stricture development.
• To evaluate the influence of urinary leakage on urinary continence recovery post-RARP.

Main Methods:

• 216 patients undergoing RARP were analyzed.
• Cystourethrography was performed before catheter removal to assess vesico-urethral anastomosis leakage.
• Patients were categorized by leakage grade (0, 1, or 2).
• Urethral stenosis and continence recovery were monitored post-operatively.
• EORTC-QLQ-PR25 questionnaire assessed functional outcomes at 12 months.

Main Results:

• Radiological urinary leakage was detected in 63 patients (29.2%).
• Only one patient (1.5%) with grade 2 leakage developed a significant urethral stricture.
• No statistically significant differences in continence recovery or urinary symptoms were observed based on catheter duration.

Conclusions:

• RARP is a safe and effective approach for localized prostate cancer.
• The technique demonstrates superiority in preventing urethral strictures and promoting continence recovery.
• Significant anastomotic urinary leakage does not appear to compromise these positive outcomes.
