Urethral reconstruction using buccal mucosa or penile skin grafts: systematic review and meta-analysis

Urethral reconstruction using buccal mucosa or penile skin grafts: systematic review and meta-analysis

Urologia Internationalis 89(4): 387-394

Different types of grafts have been described in urethral reconstruction (UR), with penile skin graft (PSG) and buccal mucosa graft (BMG) as the most frequently used ones. It still remains unclear whether one graft is superior in terms of success when compared to the other. A systematic review of the literature was performed searching the MEDLINE database with the following search strategy: 'urethroplasty' AND 'penile skin'/ 'urethroplasty' AND 'buccal mucosa'. 266 and 144 records were retrieved for urethroplasty with PSG and BMG, respectively. These records were reviewed to identify papers where PSG and BMG were used in UR and where individualized data on success were available within the same series. 18 papers were found eligible for further analysis. In total, 428 and 483 patients were respectively treated with PSG or BMG. If available, follow-up duration was 64.1 versus 42.1 months (p < 0.0001) and stricture length 6.2 versus 4.6 cm (p < 0.0001) for PSG and BMG, respectively. Success of UR with PSG was 81.8 versus 85.9% with BMG (p = 0.01). Success of UR using BMG is significantly better compared to PSG. Results might be seriously biased by a longer follow-up duration and stricture length for PSG compared to BMG.
