Botulinum toxin therapy for neurogenic detrusor hyperactivity versus augmentation enterocystoplasty: impact on the quality of life of patients with SCI.

Abstract

Cross-sectional study. To compare quality of life (QoL) in patients with spinal cord injury (SCI) who underwent overactive detrusor treatment by botulinum toxin (BT) versus augmentation cystoplasty (AC). France. Prospective and descriptive study: Patients with a refractory overactive bladder due to SCI treated by at least two successive injections of BT or by AC. QoL was assessed using Qualiveen-30 (Q30). Clinical data and urodynamic parameters were collected. Thirty patients were included between March 2013 and March 2014: 14 in arm 1 (BT injections) and 16 in arm 2 (AC). Mean postoperative time after AC was 9.94 years. Mean BT injections already performed was 6.36. Qol was significantly lower in arm 1-Q30 score 1.625 versus arm 2-Q30 score 1.077 (P=0.037). Continence control was significantly higher in arm 2. Fourteen patients were completely continent (87.5%) in arm 2, whereas only 6 (42.3%) were continent in arm 1 (P=0.0187). Urinary infection, reflux, diverticula and stones were almost at a similar occurrence level. QoL was found to be higher with an AC compared with BT injections. Long-time intervals between two injections and advantages specific to AC might explain in part these findings.
