Construction of detubularized ileal neobladder after radical cystoprostatectomy.
In an attempt to improve the patient's quality of life, we performed construction of neobladder using detubularized ileum along with radical cystoprostatectomy in 3 male patients with invasive bladder cancer. The mean followup was 28.3 months (16-45 months). All 3 patients achieved continent urination through the natural urine pathway-urethra with a satisfactory urinary stream during the day, but only 2 of them could also obtain continence in the night. Urodynamic study of the ileal neobladder showed a low pressure (mean 15.3 cm water) and no involuntary pressure spikes in the neobladder. The maximal urethral closure pressure (mean 62.0 cm water) and functional profile length (mean 3.0 cm) were adequate. In addition, the maximal uroflow rate was good (mean 16.7 ml/sec). There was no reflux in any of our patients. The radionuclide renal function study revealed that the renal function was preserved after operation in all 3 patients. Neocystourethroscopy showed no tumor and no stricture at the ileourethral anastomotic site in our 3 patients. There was no complication related to the operation. No disturbances of nutrition or electrolytes were found in any patient. All 3 patients had a satisfactory quality of life after operation though one patient died of widespread metastasis 16 months after operation. In conclusion, construction of detubularized ileal neobladder may be one of the ideal surgical procedures for bladder substitution after radical cystoprostatectomy.
