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

Abstract

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.
