OBJECTIVE: To evaluate the long-term renal function, continence, and voiding function in 64 patients, surviving for 5 or more years after W-shaped ileal neobladder with a short afferent limb and refluxing ureterointestinal anastomoses.
MATERIALS AND METHODS: Kidney morphology and function were evaluated using nuclear renography, creatinine, and glomerular filtration rate. Continence and voiding function were evaluated with a diary on frequency, voided volumes, number of pads, and with the incontinence severity index (ISI) questionnaire, the American Urological Association-Symptom Index (AUA-SI), and the American Urological Association-Symptom Problem Index.
RESULTS: The renal scan showed a dilatation of the upper urinary tract in 4.8% of renoureteral units. Of the patients, 12.5% voided with intermittent or permanent catheterization. The remaining 87.5% voided spontaneously; 75% did not use pads, 12.5% used protection for safety, 7.1% 1 pad, and 5.4% more than 1 pad, during the day; during night, 55.3% did not use pads, 23.2% used protection for safety, and 12.6% and 8.9% 1 or more than 1 pad. The ISI questionnaire showed that 35.7% were fully continent, whereas 41%, 12.5%, and 10.8% had slight, moderate, and severe incontinence. The AUA-SI showed that 50% had mild, 39.3% moderate, and 10.7% severe lower urinary tract symptoms. Urinary incontinence, daytime frequency, and nocturia correlated positively with the age of patients at follow-up and negatively with voided volume.
CONCLUSION: Long-term detrimental effect on renal function of orthotopic neobladder with no antireflux anastomoses is limited. Long-term continence and voiding function results are satisfactory. The ISI questionnaire might be useful to evaluate and grade incontinence in patients with orthotopic neobladder, whereas the AUA-SI has many limitations.
