use of silodosin to visualize the posterior urethra in pelvic floor urethral distraction defect patients

Background: retrograde urethrogram and voiding cystourethrogram are used to define length and location of urethral stricture prior to surgery. we used a single dose of silodosin prior to vcug to relax the bladder neck and achieve visualization of posterior urethra. objectives: to evaluate the efficacy of silodosin in visualization of posterior urethra during vcug, and to compare the findings with a control group. patients and methods: patients were divided into two groups a and b containing 20 and 15 patients, respectively. patients in group a were given a single dose of silodosin prior to radiological studies. results: in group a 19 out of 20 patients were able to achieve satisfactory bladder neck opening while in group b 10 out of 15 patients were able to achieve bladder neck opening. conclusions: silodosin use prior to vcug confers a statistically significant increase in bladder neck opening and visualization of posterior urethra.
