A nation-wide multi-institutional evaluation of oral versus colonic mucosal grafts for the treatment of complex long-segment urethral strictures: comparative long-term outcomes and analysis of complications from China

Key Points

• Oral mucosal grafts showed better long-term outcomes compared to colonic mucosal grafts.
• The analysis revealed a 15% lower incidence of complications with oral grafts over a follow-up period of five years.
• Multi-institutional evaluation across several hospitals documented varying success rates for graft types.
• Findings imply a preference for oral grafts in complex urethral stricture repairs, highlighting the need for careful graft selection.
