Dorsal onlay graft urethroplasty using penile skin or buccal mucosa for repair of bulbar urethral stricture: results of a prospective single center study



Dorsal onlay graft urethroplasty using penile skin or buccal mucosa for repair of bulbar urethral stricture: results of a prospective single center study



European Urology 48(6): 1013-1017



To compare the outcomes of dorsal onlay graft urethroplasty using penile skin (PS) or buccal mucosa (BM) free grafts in the repair of adult bulbourethral strictures. From January 1998 to March 2003, 30 patients with bulbar urethral strictures underwent urethral reconstruction with PS (17) or with BM free graft (13). Follow-up was done at 6, 12 and 18 months postoperatively, and every year subsequently. Success was defined as normalization of IPSS and a stable Q(max) value >20 ml/s. Any further instrumentation for stricture recurrence was considered a failure. Mean follow-up was 51 months (20-74). The overall success rate was 80% (85% in the BM and 76% in the PS group). Improvement of uroflowmetry, IPSS and QoL did not show a significant difference between the two groups. A significant improvement of the orgasmic function domain of the IIEF was found in patients treated with a PS graft. Post-operative complications were lip hypoesthesia (30%), retraction of the ventral skin of the penis (7%), post-voiding dribbling (8% with BM graft, and 7%, with PS graft). Six patients, 2 with BM (15%) and 4 with PS graft patch (24%) required further treatment due to stricture recurrence. Results of PS or BM graft are comparable at 18 month follow-up, although orgasmic function is significantly improved in patients receiving a PS graft. Nevertheless, with extended follow-up, the use of PS seems to be associated with a higher failure rate.
