[Enterocystoplasty for interstitial cystitis. Deferred results]

Interstitial cystitis is clinically diagnosed entity, characterized by irritative bladder symptoms and suprapubic pain. It is reported that up to 10% of patients are refractory to conservative management. In these patients' supratrigonal cystectomy and bladder enlargement enterocystoplasty has been used.

To evaluate the results of our series of patients that underwent this surgical technique due they were suffering interstitial cystitis refractory to conservative treatment.

We reviewed the medical records of patients that underwent supratrigonal cystectomy and bladder enlargement enterocystoplasty in our hospital between 1999 and 2006. Mictional rhythm, pre and postoperative bladder capacity measured by cystodistention, postoperative bladder capacity measured as mictional volume, surgical complications and the degree of satisfaction of patients measured by means of application of a survey were recorded. Mictional rhythms and pre and postoperative bladder capacity were compared.

15 interventions were performed. Mean preoperative bladder capacity was 125 cc, Mean preoperative mictional rhythm was 30.5 times a day. There were perioperative complications in 5 patients. The mean postoperative mictional volume was 355 cc and mean frequency was 8.26. When comparing pre and postoperative rythms and urinary volume there were statistically significant differences (p:0.0008 y p:0.0007 respectively). Regarding the survey, 13 patients were satisfied in terms of mictional frequency and 11 patients were satisfied in terms of suprapubic pain.
