[Intestinal motility and its variations in replacement bladder and intestine].
Urinary reservoirs replacing the bladder are made of intestine. The digestive tract motor activity is regulated by hormonal and neurologic mechanisms. The purpose of this work is the comparison of the motor activity in intact bowel with that of the new urinary reservoir during and after an oral intake. The modifications of pre- and post-prandial motor activities are recorded simultaneously in duodenum and neobladder by 4 patients with a tubular entero-cystoplasty (Camey I); standard meal (570 Kcal) triggers a similar activity in both segments. The modifications induced by an oral intake are then recorded by 14 patients with various reservoirs (ileum, ileum-cecum, cecum) and with different shapes (tubular or non-tubular). The compliance of non-tubular colic or ileocolic reservoirs appears greater than that of ileal reservoirs, even after detubularization. After oral intake, basal pressure and motor activity increase clearly in ileal bladders and much less in colic or ileocolic bladders. Nocturnal leak observed in many urinary reservoirs may be linked to the persistence of an intense motor activity in the neobladder with a marked increasing during the second part of the night.
