Frequently Asked Questions About Bladder Neck Contracture Treatment

A bladder neck contracture (BNC) is a narrowing or scarring at the junction between the bladder and urethra. This creates resistance to urine flow and can cause difficulty urinating, weak stream, frequent infections, and incomplete bladder emptying.

The most common cause is prior prostate surgery, particularly radical prostatectomy or TURP procedures. Other causes include radiation therapy for prostate cancer, prior bladder neck surgery, and inflammatory conditions. Risk increases with repeat procedures.

BNC has a high recurrence rate after simple endoscopic treatments like dilation or incision, especially for dense or radiation-associated contractures. Repeated procedures can make the problem worse. Definitive surgical reconstruction offers better long-term outcomes.

Success rates vary by technique and contracture severity. Endoscopic treatments range from 76-94% depending on whether the patient has had prior pelvic radiation. In experienced hands, robotic reconstruction has a 75-90% success rate depending on the case complexity.

Endoscopic procedures take 30-60 minutes. Open reconstructive surgery typically takes 2-4 hours depending on complexity. The more definitive the repair, the better the long-term outcome.

Yes, a urinary catheter is required after both endoscopic and open procedures to allow healing. For endoscopic treatments, the catheter typically stays 3-7 days. For open reconstruction, it may remain 2-3 weeks.

Most endoscopic procedures cause minimal discomfort. Open reconstructive surgery requires a longer recovery but pain is well-managed with medication. Most patients find the improvement in urinary function well worth any temporary discomfort.
