[Functional status of urinary tract after plastic surgery of the urinary bladder with a segment of the ileum (experimental study)].

Abstract

Replacement of the gall bladder with an isolated ileal segment was made to evaluate function of the urinary tracts depending on configuration of the created urine reservoir early and late after the operation in dogs. Intestinoplasty of the gall bladder changes parameters of ureteral function. Upper urinary tract urodynamics after ileocystoplasty is characterized by lowering of intraureteral pressure, decreased amplitude of the contractions, high tonicity and motility. The intestinal bladder has the same mean basal pressure at rest but less when full than the control animals. Reflex urination after the bladder reconstruction in subtotal resection was intact. Detubulized urinary reservoir had low intravesical pressure and no spontaneous contraction activity.
