A consecutive series of 18 patients underwent attempted direct vision internal urethrotomy (DVIU) under topical lidocaine anesthesia. The procedure was completed successfully in 15 of 18 (83%) patients. In these patients 12 of 15 (80%) reported either minimal or no discomfort. Direct vision internal urethrotomy using topical lidocaine anesthesia is a safe and cost effective procedure.
