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.
