[Urodynamic study of the behavior of detubulated ileocystoplasties according to feeding]

Twenty-three patients having undergone enterocystoplasty with a detubulated graft has an urodynamic study on an empty stomach and after a standardized meal. All patients (average age 62.9 years) had been operated more than 6 months earlier, and 30% still presented with urine leakages at night. The urodynamic study included a cystomanometric measurement with rapid water filling, an urethral profile and a micturating cystography. It was repeated 60 to 90 minutes after a meal composed of glucids, lipids and protids. Feeding had variable effects on the intestinal graft: increase in peristaltic intensity and/or earlier onset of contractions (10/23); apparently paradoxical decrease in contractions (6/23); sometimes no modification (7/23). This short work without any obvious physiopathological explanation has led us to advocating breaking up feeding for patients who were improved by the meals.
