Abstract PURPOSE: We developed a reproducible animal model for the induction of urethral stricture in the rabbit and evaluated the role of halofuginone in limiting stricture formation. MATERIALS AND METHODS: A total of 20 New Zealand male rabbits were used in the first phase of the experiment. Bulbar urethral stricture was induced by electrocoagulation. The animals were then randomly assigned to 2 groups of 10 each, which received a diet containing halofuginone or a normal diet. In the second phase electrocoagulation induced stricture was treated with visual internal urethrotomy in 45 rabbits. These rabbits were randomly assigned to 2 groups, namely a halofuginone and a control group. RESULTS: In the first phase stricture developed in 2 study rabbits (20\%) vs 10 controls (100\%). In the second phase 37 rabbits were evaluable (8 died). Recurrent stricture was observed in 5 of the 18 study rabbits (27\%) vs 14 of the 19 controls (73\%). CONCLUSIONS: Halofuginone is effective in limiting the occurrence of de novo urethral stricture and recurrent stricture after visual internal urethrotomy. This antifibrotic molecule may become an important therapy to treat urethral stricture and/or recurrence following endoscopic manipulation of stricture in humans.
