Urodynamic Analysis of the Ileocolic Neobladder / 대한비뇨기과학회지

From May 1991 to December 1993, 30 male bladder cancer patients with 34 to 68 years old age (mean age 52.4 years) underwent bladder replacement with the ileocolic neobladder. A divided segment of ileum and colon was used to create a neobladder after radical cystectomy with a cecourethral anastomosis to provide volitional voiding with continence. Urodynamic studies were followed up 3, 6, l2 and 18 months postoperatively. The mean maximal reservoir capacity was 420+/-87.7, 553+/-65.3, 565+/-60.3, 563+/-53.5ml, mean maximal reservoir pressure was 33.2+/-7.5, 24.2+/-6.1, 24.0+/-5.9, 23.1+/-6.3cmH2O, mean maximal urethral closure pressure was 57.9+/-9.5, 61.3+/-7.6, 61.0+/-7.3, 61.5+/-6.9cmH2O, maximal flow rate was 23.2+/-7.2, 24.3+/-5.8, 24.0+/-6.1, 24.1+/-5.4ml/s and residual urine was 40.0+/-10.3, 35.0+/-7.8, 24.0+/-6.1, 24.1+/-5.4ml/s. The daytime continence rate was 100% and the nighttime continence rate was 93% at 6 months postoperatively. With its very good functional results and its ease of performance, ileocolic neobladder may be one of the ideal urinary diversion for bladder substitution after radical cystectomy.

Vesicocolonic Fistula / 대한비뇨기과학회지

Vesicocolonic fistula is an uncommon but significant complication of inflammatory and neoplastic disease. We report two cases of vesicocolonic fistula in adenocarcinoma of the sigmoid colon with turbid urine and irritative voiding symptoms. A literature review of vesicoenteric fistula is presented.

Percutaneous Nephrolithotomy in Kyphosis Patients / 대한비뇨기과학회지

Percutaneous removal of renal and upper ureteral stone is becoming an established procedure, especially for stones lying free in the pelvis. The kidneys, which are frequently malformed. often lay within the kyphosis and it is hard to do open surgery. We report 4 cases of renal or upper ureteral stones managed with percutaneous nephrolithotomy(PNL) in kyphosis patients.
