Abstract:

Objective To summarize experience with transurethral incision of the bladder neck(TUIBN) for the treatment of female bladder outlet obstruction(FBOO). Methods Bladder outlet obstruction was diagnosed in 28 women 52 to 73 years of age, who presented with the lower urinary tract symptoms. Preoperative investigations included a urodynamic examination and cystoscopy. The maximal flow rate was from 4.2 mL/s to 15.2 mL/s(mean(7.5±3.1) mL/s). Transurethral incision of the bladder neck(TUIBN) was performed in all patients. Urodynamic result and clinical symptoms were assessed after operation. Results The lower urinary tract symptoms were resolved or improved in 26 patients. Urodynamic examination revealed an increased maximal flow rate and a decreased postvoid residual urine volume. The maximal flow rate was from 13.6 mL/s to 24.8 mL/s(mean(14.3±4.1) mL/s)(P<0.01) and postvoid residual urine(RU) volme was from 0 to 30 mL at one month postoperation. The follow-up period was from 6 months to 1 year. Conclusion Transurethral incision of the bladder neck(TUIBN) is effective in relieving the lower urinary tract symptoms owing to female bladder outlet obstruction(FBOO). Urodynamic evaluation is essential in making the correct diagnosis.
