Supratrigonal cystectomy and augmentation cystoplasty with ileum or ileocecum in the treatment of ulcerative interstitial cystitis/bladder pain syndrome: a 14-year follow-up.

INTRODUCTION AND HYPOTHESIS

This study analyzes the long-term results of supratrigonal cystectomy and augmentation cystoplasty in patients with severe ulcerative interstitial cystitis/bladder pain syndrome (IC/BPS) and reduced bladder capacity.

METHODS

Outcome data were retrospectively and prospectively collected and analyzed in women who underwent supratrigonal cystectomy and augmentation cystoplasty for ulcerative IC/BPS at Muenster University Hospital between 1991 and 2006. We used cross-tabulation and Pearson's Chi-squared test to examine how outcome is influenced by age, preoperative functional bladder volume, and choice of augmentation material.

RESULTS

After a median 171-month follow-up, analysis could be done in 26 of 27 patients. Persistent pain necessitated early revision in 2 patients (7.7%). Mean postoperative O'Leary Sant IC Score was 12.7 in the prospectively questioned patients. Responses to Patient Global Impression of Improvement (PGI-I) were: "very much better" in 15 cases (65.2%) and "much better" in 7 (30.4%). Twelve patients (52.2%) emptied their augmented bladder voluntarily, whereas 7 (32%) needed intermittent self-catheterization (ISC). The rate of patients requiring ISC tended to be lower when detubularized ileocecal bowel was used. All 5 patients (19.2%) with late relapse of ulcerative IC/BPS needed ISC.

CONCLUSIONS

Severe ulcerative IC/BPS can be curatively treated in some patients by supratrigonal cystectomy and augmentation, which is associated with a high satisfaction rate and few long-term complications even over a very long follow-up. In our analysis, the need for ISC is a risk factor for late relapse, although ileocecal augmentation could increase the proportion of patients with sufficient voluntary micturition.
