Effectiveness of Solifenacin for Managing of Bladder Spasms in Patients With Urethroplasty.

To evaluate the efficacy and safety of solifenacin in the treatment of bladder spasms after urethroplasty. Patients underwent urethroplasty were randomly assigned to the study group ( n = 165) and the control group ( n = 150). Patients in the study group were treated with solifenacin for 7 days. Patients in the control group were placebo. Each group was further divided into four subgroups: paracentetic suprapubic cystostomy subgroup, traditional suprapubic cystostomy subgroup, former suprapubic cystostomy subgroup, and urethral catheter subgroup. A visual analogue scale (VAS) was used to measure the severity of bladder spasms. The mean duration of spasms, the frequency of spasms, and the incidences of urine extravasation and radiating pain were recorded each day. There were no significant differences in the VAS scores and mean duration of bladder spasms between the study and control groups . However, there was a significantly lower VAS score in the patients taking solifenacin in the paracentetic suprapubic cystostomy subgroup ( p < .05). A similar tendency was noted in the mean duration of bladder spasms in this subgroup. In a comparison of the daily and nightly frequency of spasms within the four subgroups, a significant improvement was noted in the control group within 5 days. A similar difference was not noted within 6 days in the study group. The short-term therapy with solifenacin is an effective and safe method for decreasing the frequency of bladder spasms after urethroplasty. Patients undergoing paracentetic suprapubic cystostomy might be the only subset to benefit from this treatment.
