‘Pee’BuSt Trial: A single-centre prospective randomized study comparing functional and anatomic outcomes after augmentation  urethroplasty with penile skin graft versus buccal mucosa graft for anterior urethral stricture disease

PURPOSE: To assess the surgical outcomes of augmentation urethroplasty (AU) using penile skin graft (PSG) compared to buccal mucosa graft (BMG) in anterior urethral stricture disease. METHOD: Between January 2018 and January 2019, 100 patients with anterior urethral stricture planned for AU were ran...

Sumario:PURPOSE: To assess the surgical outcomes of augmentation urethroplasty (AU) using penile skin graft (PSG) compared to buccal mucosa graft (BMG) in anterior urethral stricture disease. METHOD: Between January 2018 and January 2019, 100 patients with anterior urethral stricture planned for AU were randomized into PSG or BMG arms (CTRI/2018/07/015028). Anatomic and functional variables were compared pre-operatively and post-operatively. Primary outcome was success rate at 18 months and it was defined if any of the three criteria were met, i.e. either maximum urinary flow (Qmax) > 15 ml/s or urethral calibration of 16 French or ability to traverse the repair with 17 French cystoscope. Secondary outcomes were functional parameters such as International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF) Score, Male Sexual Health Questionnaire for Ejaculatory Dysfunction (MSHQ-EJD), and Urethral Stricture Surgery-Patient Related Outcome Measure (USS-PROM). RESULTS: Pre-operative variables were comparable between both the arms. Median duration of follow-up was 22 months (18–24 months). At 18 months, the success rates of AU with PSG and BMG were comparable (89% v/s 91%; p = 0.70, 95% CI-0.33 to 5.21). The improvements in Qmax (p = 0.06), IPSS (p = 0.43) and USS-PROM (p = 0.49) were comparable between the two arms. There was no statistically significant difference in the IIEF-Erectile domain (p = 0.07), IIEF-Orgasmic domain (p = 0.11) and MSHQ-EJD (p = 0.20) following AU at 18 months. Clavien–Dindo grade I complications were 12.7% in PSG and 16.7% in BMG. CONCLUSION: This study provides level 1 evidence of no statistical significant difference in outcomes of AU using BMG or PSG.
