Long-term functional outcomes of augmentation cystoplasty in adult spina bifida patients: A single-center experience in a multidisciplinary team

To report the very long-term functional outcomes of augmentation cystoplasty (AC) in adult spina bifida patients.

All consecutive adult spina bifida patients who underwent AC between 1991 and 2008 were enrolled. Early postoperative complications (Clavien-Dindo classification) and long-term outcomes (voiding modalities, urodynamic parameters, renal function, continence, and quality of life) were assessed.

Twenty-eight patients with a median age of 20 years (IQR 17-25) were included. They all underwent AC with a supratrigonal cystectomy (SC). The median follow-up was 13.6 years (IQR 6-16.5). Thirteen early postoperative complications (12 grade I-II, 1 grade III) were observed in 11 patients (39%). Eight patients (29%) had upper urinary tract infections managed with antibiotics, with 2 patients requiring ureteral stents. Bladder stones occurred in 2 patients (7%) and were managed with endoscopy and cystostomy. One bladder perforation was reported. One bladder cancer was observed 26 years after surgery. Creatinine clearance and all urodynamic parameters were significantly improved post-operatively. The overall complication and reoperation rates were 57% and 14%, respectively. At last follow up, the continence rate was 71% (n = 20), with 93% (n = 26) performing intermittent self-catheterization. Quality of life was improved for 71% of patients.

In adult spina bifida population, AC is a high-risk procedure with an overall complication rate of 57% and a reoperation rate of 14%. However, AC is beneficial to the overall health of the patients since it provides a satisfying continence rate, an improvement of quality of life, and long-term protection of the upper urinary tract.
