Medium-term outcome after stented and un-stented distal urethroplasty: A retrospective analysis on redo-urethroplasty need and cosmetic results

Introduction: Long-term complication rates after distal hypospadias repair can be close to 20%. There are no available guidelines regarding the need of a catheter in distal urethroplasty. We report a retrospective analysis on medium-term redo-urethroplasty rate and cosmetic results after a two-year pilot study on stented/un-stented distal urethroplasties.

Materials and methods: A total of 11 stented (Group A) and 17 un-stented (Group B) Snodgrass-procedures were performed by one pediatric surgeon at our Institution (2011-2013). The median age at surgery was 2.1 years (range 1-8.5). Inclusion criteria were primitive distal defect, same surgeon in both interventions, catheter-free discharge. The median follow-up was 6.4 years (range 1.5-8.1). All patients received at least one post-operative clinical-cosmetic examination (HOSE). The aim of our study was to compare medium-term complications and redo-urethroplasty rates before starting a randomized study. A retrospective analysis was performed. We used Fisher's exact-test (P<0.05) for statistical analysis.

Results: Of 28 complications, 5 required redo-surgery: 2/11 stented-cases, 3/17 un-stented. Cosmetic results were satisfactory in both groups. These results were not statistically significant (P=1.000).

Conclusion: Long-term follow-up is mandatory to know redo-urethroplasty rate and cosmetic outcome after distal stented/un-stented repair. Further studies are needed to evaluate the role of catheter placement and the definitive outcome in distal urethroplasty.
