ABSTRACT

Background: The urethral strictures occurred due to narrowing of urethra. These may occur after an injury or ureteral or excretory system diseases, due to the injury to urothelium or corpus spongiosum that lead to the development of scar tissues. Mitomycin C can be used as chemotherapeutic agent because of its quality of being anti-tumour actions.

Aim: To compare the recurrence rate of strictures after internal optical urethrotomy with intralesional injection of Mitomycin C versus without Mitomycin C injection in patients presenting with anterior urethral stricture.

Study Design: Randomized controlled trial.

Place and Duration of Study:  Department of Urology, Lahore General Hospital, Lahore from 5^th September 2016 to 5^th March 2017.

Methodology: Sixty male patients age 18-70 years, diagnosed with anterior (penile and bulbar) urethral stricture up to 2.0cm were included. Patients were randomly divided into two groups; Group A patients were treated with internal optical urethrotomy alone and Group B patients treated with internal optical urethrotomy with intralesional injection of Mitomycin C. After the procedure, an 18F or 20F indwelling catheter left for 7 days. After 6 months, surgical site evaluated and if stricture again developed, then recurrence labeled.

Results: The mean age was 39.32±11.38 years, mean duration of stricture was 6.85±3.32 months and the mean stricture size was 1.21±0.45 cm. The recurrence occurred in 18 (30%) patients. Significant difference was noted for recurrence in both groups (p-value<0.05).

Conclusion: The recurrence rate with anterior urethral stricture is significantly lower in with Mitomycin C as compared to without Mitomycin C.
