Abstract
We evaluated the quality of micturition in patients with orthotopic neobladder replacement. In the present study, 58 patients who had undergone orthotopic neobladder replacement following cystectomy were enrolled. The quality of micturition was evaluated by means of uroflowmetry, a self-administered questionnaire and a 24-h frequency-volume chart. The questionnaire consisted of 26 questions concerning storage (9 questions), evacuation of urine (9), patient's satisfaction with neobladder (3), limitations in daily life (3) and pain (2). In addition, 11 of the questions were followed immediately by a question concerning inconvenience to the patients. The mean follow-up period was 35 months (range 6-80). On uroflowmetry, the mean peak flow rate was 13.5 ml/s with a low average flow rate (mean: 5.7 ml/s), and the voiding time was considerably prolonged (mean: 70.2 s). According to the frequency-volume chart and questionnaire responses, although the frequency and tidal volume of micturition were normal, the majority of patients were conscious of retarded, intermittent, prolonged, and weak stream and of straining during voiding. Diurnal or nocturnal incontinence was noticed subjectively in as many as 69% of the patients. However, the degree of urine leakage was minimal. In spite of the fact that 66% of the patients replied that their micturition status was worse than before surgery and that 69% of the patients felt dissatisfied, the degree of inconvenience was low in every item and the limitations in daily life were minimal. Although micturition in patients with neobladder replacement appeared to be of lower quality than that in normal subjects and was considered by many to be unsatisfactory, most patients were able to adjust themselves to it without significant inconvenience.
