Outcome of endoscopic bladder transection

Objective To determine the clinical, symptomatic and Objective urodynamic outcome of patients undergoing endoscopic bladder transection. Patients and methods The study included 20 men and 30 women (mean age of 50±15 years, range 20–86) who underwent endoscopic bladder transection. Their underlying diagnoses were idiopathic detrusor instability (41), enuresis with instability (6), multiple sclerosis (2) and Parkinson's disease (1). A full‐thickness endoscopic transection of the bladder was performed under general anaesthesia. Subjective assessment was performed using symptom scores (0–14 points) and a Visick grading system (group A‐E). Objective assessment was carried out using urodynamic studies. The mean follow‐up period was 6 years (57 ± 22 months, range 6–85). Results The mean hospital stay was 8 ± 3 days (range 3–22). No patients died after the operation. Postoperative complications included extra‐peritoneal extravasation (2), recurrent urinary tract infection (5) and urethral stricture (1). Symptom scores before and after the operation were 9±2 (range 4–14) and 8 ± 3 (range 1–14) points respectively. The overall outcome of the procedure was satisfactory in only eight (16%) patients. The mean duration of symptomatic relief was 17 weeks (range 3–53). There was no significant difference between urodynamic results before and after the operation. Bladder instability observed in all patients before operating was demonstrated in 93% of patients after the operation. Conclusion The results of our study suggests that endoscopic bladder transection produces only a transient symptomatic relief in a few of those patients who have failed to respond to pharmacological manipulations. We do not feel that its continued role is justified.
