Urethral stricture dilatation can be performed in an outpatient treatment room under local anaesthesia using sterile Instillagel and patient-administered Entonox (nitrous oxide gas) for pain relief.

The procedure involves the gentle insertion of progressively larger dilators into the urethra to stretch a narrowed segment (urethral stricture) and restore urinary flow. It is typically indicated for men experiencing poor flow, straining, or incomplete bladder emptying due to a known or suspected urethral stricture.

Flexible cystoscopy is usually performed beforehand to confirm the location and extent of the narrowing. The goal is to relieve obstruction while ensuring patient comfort and avoiding general anaesthesia. Repeat dilatation may be required depending on the severity and recurrence of the stricture.

A follow-up assessment, including urinary flow rate and post-void residual bladder scan, is typically arranged three months after the procedure.
