Ureteroplasty with buccal mucosa graft without omental wrap: an effective method to treat ureteral strictures

Abstract

PurposeSuccessful treatment options for ureteral strictures are limited. Surgical options such as ileal interposition and kidney autotransplantation are difficult and associated with morbidity and complications. Techniques such as Boari flap and psoas hitch are limited to distal strictures. Only limited case studies on the success of open buccal mucosa graft (BMG) ureteroplasty exist to this date. The purpose of this study was to evaluate the success of open BMG ureteroplasty without omental wrap.MethodsIn this single-center retrospective study between July 2020 and January 2023, we included 14 consecutive patients with ureteric strictures who were treated with open BMG ureteroplasty without omental wrap. The primary outcome was the success of open BMG ureteroplasty. Further endpoints were complications and hospital readmission. Outcome variables were assessed by clinical examination, kidney sonography, and patient anamnesis.ResultsOut of 14 patients, 13 were stricture and ectasia-free without a double-J stent at a median follow-up of 15 months (success rate 93%). No complications were observed at the donor site, and the complication rate overall was low with 3 out of 14 patients (21%) having mild-to-medium complications.ConclusionsOpen BMG ureteroplasty without omental wrap is a successful and feasible technique for ureteric stricture repair.
