Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators propose a randomized non-blinded comparison of dorsal vs. ventral approach for buccal mucosa graft urethroplasty in the bulbar urethra. Buccal mucosa graft is a common method of repairing the strictured urethra. Current evidence suggests the two approaches for placement of the graft are equally successful at correcting the stricture and the two approaches have similar risks of complications. The investigators propose to randomly assign appropriately selected patients to either a dorsally- or ventrally-placed graft. No additional procedures beyond normal care protocol will be required of the patients. Success will be assessed via objective and subjective methods; complications will be tallied in a standardized fashion. Outcomes will be measured at two years.
