Intralesional Injection of Mitomycin C Following Visual Internal Urethrotomy for Recurrent Urethral Stricture

Intralesional Injection of Mitomycin C Following Visual Internal Urethrotomy for Recurrent Urethral Stricture

To evaluate the effectiveness of administering mitomycin C through intralesional injection after performing visual internal urethrotomy (VIU) for the treatment of recurring urethral stricture.

Numerous studies have investigated the impact of intralesional administration of antifibrotic drugs on urethral strictures following visual internal urethrotomy (VIU). These drugs include mitomycin C, botulinum toxin A, somatostatin analog, and glucocorticoids. Mitomycin C (MMC) is known for its potent chemotherapeutic and antibiotic properties. It effectively hinders mitosis and fibroblast proliferation, playing a crucial role in tissue healing and scar formation by reducing the release of matrix proteins through the inhibition of proliferative fibroblasts. With its anti-proliferative and anti-scarring characteristics, MMC proves to be a suitable option for treating recurrent urethral strictures.

thus we conduct a randomized controlled trial to evaluate the safety and efficacy of Mitomycin in decrease urethral stricture recurrence.
