BACKGROUND: The use of buccal mucosa grafts (BMG) for urethral reconstruction has increased in popularity over the last several decades. Our aim was to describe our institutional experience with and outcomes after BMG urethroplasty.
METHODS: We conducted a retrospective cohort study of boys undergoing BMG urethral reconstruction. Preoperative and perioperative characteristics and postoperative outcomes were evaluated.
RESULTS: Twenty-nine patients (median age 8.2 years) underwent BMG urethroplasty from 1995-2012. Of the 10 patients undergoing 1-stage repairs, 6 had tubularized grafts, the last of which was performed in 2000 due to an unacceptably high revision rate (100%). A 2-stage approach was elected for 19 patients (median follow-up 21.3 months). Complications including stricture, fistula, or chordee were seen in 60% of patients completing both stages and 32% required ≥1 revision. However, 71% of 2-stage patients were free of significant problems at last follow-up.
CONCLUSIONS: We found BMG to be a reasonable option for use in complex pediatric urethral reconstruction. Tubularized grafts had poor results, and we no longer use them. We favor a 2-stage approach for all patients except those with "simple" non-hypospadiac strictures. Although revision procedures were not uncommon, the majority of patients were ultimately free of long-term problems.
