Functional and urodynamic characteristics in patients with ileal neobladder

We analyzed the functional and urodynamic characteristics in 19 patients with ileal neobladder by the Hautmann procedure. A questionnaire survey by mail was performed for functional information of neobladder. Seventeen of the 19 patients (89.5%) could voluntarily void via the urethra and the others needed clean intermittent self catheterization (CIC) because of their significant residual volume. Eight of the 19 patients (42.1%) micturated at least two times at night. Two of the 19 patients (10.5%) were incontinent in the day time and 12 (63.2%) in the night time. They needed 2 pads in the day time and one pad at night on average. Eight out of 18 patients (44.4%) were satisfied with their micturition state. A urodynamic study showed the neobladder to be a low-pressure reservoir with a mean capacity of 395.2 +/- 96.8 ml. The mean residual volume of the patients without CIC was 27.8 +/- 28.2 ml. In 10 out of 11 patients high frequency and high amplitude spikes were seen by the perineal electromyogram in the voiding phase.
