Direct vision internal urethrotomy is a safe, effective means to treat urethral strictures and vesical neck contractures. Its success rate approaches 90 per cent with 6 months of followup, although a longer interval may be necessary for a more accurate record. It often can be performed in an outpatient setting, under topical anesthesia and with only 1 day of catheter drainage, which provides considerable savings in hospital costs.
