Objectives To investigate the efficacy and complications of controlled transurethral resection and incision of the bladder neck to treat female primary bladder neck obstruction. Methods A total of 59 patients who were diagnosed with female primary bladder neck obstruction by urodynamic examination underwent surgical procedures at Urological Institute of the People's Liberation Army, First Affiliated Hospital of Third Military Medical University, Chongqing, China, between March 2010 and March 2014. For all patients, neurogenic, anatomical and dysfunctional voiding causes of bladder outlet obstruction had been excluded. Perioperative and follow‐up data, including operative time, maximum urine flow rate, residual urine volume, International Prostate Symptom Score and Quality of Life Score, were prospectively investigated. Results All of the operations were completed uneventful. The median operative time was 15 ± 8 min (range 10–22 min). No massive hemorrhage or infection was reported. Follow‐up data were available for 59, 59, and 57 of the patients at 1, 6 and 12 months postoperatively, respectively. The mean maximum urine flow rate increased from 7.2 ± 3.9 mL/s preoperatively to 26.1 ± 5.2 mL/s postoperatively. The mean residual urine volume decreased from 162 ± 75 to 20 ± 7 mL. The mean International Prostate Symptom Score decreased from 24.5 ± 7.2 to 5.5 ± 3.6. The mean Quality of Life Score decreased from 5.4 ± 1.7 to 1.9 ± 1.1. All of the differences between the preoperative and postoperative values were significant ( P < 0.001). Conclusions The novel technique described here shortens the length of the urethra to 2.5 cm, which both released the obstruction and maintained continence. The results of the present preliminary study show that this method represents a safe and effective treatment for female primary bladder neck obstruction.
