Objective To describe the modified surgical technique and report the long-term outcomes of modified transurethral incision for the treatment of primary bladder neck obstruction in women. Methods A total of 30 women were diagnosed with primary bladder neck obstruction from the videourodynamic study findings according to the Blaivas-Groutz nomogram for female bladder outlet obstruction. Patients with neurogenic, traumatic, anatomic, or iatrogenic causes of obstruction were excluded. The transurethral incision of the bladder neck was performed in all patients, with the modification of incising at 4 different sites on the bladder neck, at the 3-, 6-, 9-, and 12-o'clock positions. The urodynamic results and clinical improvement in voiding symptoms were assessed before surgery and 3, 48, and 60 months after treatment. Results Follow-up data were available for 30 (100%), 28 (93%), and 25 (83%) of the 30 patients at 3, 48, and 60 months postoperatively, respectively. During the 5-year follow-up, the mean International Prostate Symptom Score decreased from 23.3 to 5.9. The mean quality of life scores decreased from 4.4 to 2.1. The mean peak urinary flow rate increased from 7.61 to 17.53 mL/s. The mean postvoid residual urine volume decreased from 185.11 to 28.75 mL. The mean voiding detrusor pressure decreased from 62.12 to 21.92 cm H2O. All 25 patients had improvement in both objective and subjective voiding functions 5 years after this modified treatment. Only 1 woman (3%) had mild stress incontinence postoperatively and was cured after the patient performed levator ani exercises. Conclusion The modified transurethral bladder neck incision is effective in the long term in relieving voiding difficulties owing to primary bladder neck obstruction in women without urinary incontinence.
