Robot-assisted modified Y-V plasty for bladder neck contracture: single-center comparative analysis.

Area of Science:

• Urology
• Surgical Innovation
• Patient Outcomes Research

Background:

• Bladder neck contracture (BNC) is a common complication after surgery for benign prostate hyperplasia (BPH).
• Y-V plasty is a reconstructive option for refractory BNC.
• Comparing robot-assisted modified Y-V plasty (RAMYV) with traditional Y-V plasty (RAYV) is crucial for optimizing BNC treatment.

Purpose of the Study:

• To compare the efficacy of RAMYV and RAYV in treating refractory BNC.
• To identify potential predictors for postoperative patient-reported outcomes (PROs).

Main Methods:

• Retrospective analysis of patients with refractory BNC undergoing RAMYV or RAYV.
• Follow-up assessments at 1, 3, and 6 months post-surgery.
• Evaluation of urinary flow rates, residual urine, and patient-reported outcome measures (PROMs).

Main Results:

• Both RAMYV and RAYV resulted in patent repairs and improved voiding.
• RAMYV demonstrated superior outcomes in IPSS, USS-PROM, QoL, and OAB-V8 at 3 and 6 months compared to RAYV.
• Age and preoperative symptom scores (IPSS, USS PROM) were identified as significant predictors of postoperative outcomes.

Conclusions:

• Y-V plasty is effective for refractory BNC.
• RAMYV shows improved efficacy over RAYV for patient outcomes at six months.
• Baseline patient characteristics and symptom scores can predict surgical success.
