Mild cases of bladder neck obstruction in women are treated with antibiotics, alpha-blockers and urethral dilatation, but long-term outcomes are poor and prone to recurrence. Surgery is now performed by transurethral cystocele incision. The patient was placed in a truncated position and an olympus electrodesiccope was used. The power of electrodes is 120 W, and the power of electrocoagulation is 60 W. The electrodes (electrodes ring) are used to perform electrodes at 5-7 points in the bladder neck, and the depth is cut to the deep layer of the ring fibers of the neck, so that the bladder triangle is at the same level or oblique plane with the posterior urethra, and the length of electrodes is about 1.5-2 cm to prevent urinary incontinence. Careful hemostasis was performed, and a two-lumen balloon catheter was left in place for 3-5 days after surgery. Urodynamic examination can be performed six months after surgery to compare the change in urinary flow rate before and after surgery.
