Abstract

To analyze the urodynamic behavior of the intestinal neobladders in our series. The study comprised 20 patients with a detubularized intestinal neobladder. The ileal segment was utilized in 15 (13 Melchior, 1 Camey and 1 Padovana), the ileocecal segment in 4 (3 Mainz, 1 Le Bag) and detubularized sigmoid in one patient. A urodynamic study was performed in all patients to determine neobladder capacity, presence of peristaltic waves, filling and voiding pressures, peak and mean urinary flow and postvoid residual urine. The patients were also asked about continence, if a collecting device was required and the overall degree of satisfaction. Mean neobladder capacity was 508 ml., mean reservoir accommodation was 38 ml/cm H2O and 66.7% presented significant peristaltic contractions. Maximum filling pressure was 27 cm H2O. All patients showed peaks in the flowmetry due to the abdominal pressure, with a mean maximum peak flow of 16.6 ml/sec. Mean postvoid residual urine was 43.6 ml. Eighty percent of the patients were continent during the day, 55% were continent during the night and 25% were completely continent. All patients used abdominal pressure for voiding and generally in the sitting position. The overall degree of satisfaction wa...Continue Reading
