Resumen:
Purpose: To critically evaluate a multi-institutional patient cohort undergoing single-stage distal urethral repair using a novel transurethral buccal mucosa graft inlay urethroplasty technique (TBMGI).
Methods: A retrospective multi-institutional review of consecutive patients with fossa navicularis (FN) strictures treated with a single-stage TBMGI technique at 12 institutions from March 2014-March 2018 was performed. Patient demographics, stricture characteristics, clinical and patient-reported outcomes were analyzed. The primary outcomes were stricture recurrence and complications. Secondary outcomes were change in maximum urinary flow rate (Qmax), PVR, and changes in IPSS, SHIM and global response assessment (GRA) questionnaire responses. Descriptive statistical analysis was used for evaluation of outcomes.
Results: Sixty-eight men met inclusion criteria. Median age and stricture length were 60 years (IQR 48-69) and 2 cm (IQR 2-3), respectively. Most common stricture etiology was lichen sclerosus (34%). Median operative time and EBL were 72 min (IQR 50-120) and 20 mL (IQR 10-43), respectively. Fifty-seven men completed ≥ 12-month follow-up. At a median follow-up of 17 months (IQR 13-22), 54...
