Figure 5: Rabbit urethrogram findings at evaluation. (a) Comparison of urethrograms in each group 1 month and 3 months after urethroplasty. (b) Complications revealed by urethrogram: complete stenosis (black), urethral narrowing (<66.7% control; gray), fistula (hatching), no complication (white). (c) The neourethral patency at evaluation. Narrowest lumen calibers of the neourethra were measured on urethrograms at 1 month and 3 months and were analyzed as percentage of the urethra caliber of control rabbits not submitted to any surgery (n = 4). Statistical significance (one sample t-test towards the theoretical mean of 100%) is shown as *P < 0.05. Arrow: the fistula site of the urethra.
