Improved Early Urinary Continence After Robot-Assisted Radical Prostatectomy Using a Modified Vesicourethral...

Area of Science:

• Urology
• Surgical Innovation
• Functional Outcomes

Background:

• Post-prostatectomy incontinence (PPI) is a significant complication following robot-assisted radical prostatectomy (RARP).
• Posterior musculofascial reconstruction (PMFR) aids early urinary continence (EUC), but technique variations may optimize results.
• The standard Van Velthoven anastomosis (ST-VUA) is commonly used for vesicourethral anastomosis (VUA).

Purpose of the Study:

• To compare the efficacy of a modified pontine VUA (P-VUA) technique with simultaneous PMFR against the standard ST-VUA.
• To evaluate the impact of P-VUA on the speed and rate of urinary continence recovery after RARP.

Main Methods:

• A prospective comparative study of 157 patients undergoing RARP between January 2021 and December 2023.
• Patients were allocated to either ST-VUA or P-VUA based on surgeon preference.
• Urinary continence (UC) was assessed at multiple time points post-catheter removal (10, 30, 90, 180, 365 days).

Main Results:

• The P-VUA group demonstrated significantly shorter catheterization times (5.0 vs. 6.7 days).
• Higher continence rates were observed in the P-VUA group across all assessed time points (e.g., 84.0% vs. 68.4% at 30 days).
• Kaplan-Meier analysis and multivariable regression confirmed that P-VUA was independently associated with faster and improved 30-day continence.

Conclusions:

• The P-VUA technique appears to facilitate faster urinary continence recovery post-RARP compared to ST-VUA.
• Integrating anatomical reconstruction into the anastomotic step may enhance functional outcomes after RARP.
• Larger, randomized studies are needed to confirm these findings due to the current study's design and sample size.
