Abstract
AIMS: To investigate the functional outcome after supratrigonal cystectomy and augmentation ileocystoplasty in adult patients with refractory neurogenic lower urinary tract dysfunction (NLUTD). METHODS: Retrospective follow-up investigation in a single spinal cord injury rehabilitation center. In 29 patients, urodynamic data before and after supratrigonal cystectomy and augmentation ileocystoplasty, clinical outcome and post-operative complications were evaluated. RESULTS: The median age of the 29 patients at the time of surgery was 31 years, a median 14 years after NLUTD had occurred. At the last follow-up visit (median 2.4, range 0.4-9.0 years post-operatively), 20/29 patients (69%) were continent compared to 2/29 pre-operatively (P = 0.001). Furthermore, 16 patients required no or less detrusor relaxation therapy after augmentation ileocystoplasty. Augmentation cystoplasty resulted in a significant (P = 0.001) increase in the median bladder capacity (from 240 ml to 500 ml) and compliance (from 13 ml/cm H2 O to 50 ml/cm H2 O). The median maximum detrusor pressure had decreased significantly (P = 0.001) from 38 cm H2 O to 15 cm H2 O. Significantly (P = 0.001) fewer patients presented with a risk for renal damage (1 vs. 15 with maximum detrusor pressure >40 cm H2 O and 1 vs. 12 with detrusor compliance <20 ml/cm H2 O) at the last follow-up. The following complications were observed in 11/29 (38%) patients: paralytic and obstructive ileus, impaired bowel function, bladder stones, dehiscence, metabolic acidosis and autonomic dysreflexia. CONCLUSIONS: Protection of renal function, adequate bladder capacity and low detrusor pressure can be achieved using supratrigonal cystectomy and augmentation ileocystoplasty in patients suffering from refractory NLUTD.
