1613 THE ROLE OF URETHRAL FROZEN SECTION AT CYSTECTOMY IN THE MANAGEMENT OF BLADDER CANCER Ardalan E Ahmad*, Anobel Y Odisho, Kirsten L Greene, Maxwell V Meng, Peter R Carroll, Badrinath R Konety.

Of these, 43 patients did not have a FS of the urethral margins and were excluded. Demographic, clinical and pathological variables of the remaining 157 patients were examined retrospectively. RESULTS: 35/157 (22%) of patients had pre-operative prostatic urethral biopsy of whom 14 (40%) were positive. Of these 14 patients, 6 (43%) also had a positive distal urethral FS at cystectomy. 2/21 (10%) of patients with negative pre-cystectomy prostatic urethral biopsies had positive urethral FS at cystectomy.

CONCLUSIONS: The prevalence of a positive margin at the urethra on FS at cystectomy is low and similar to that of positive ureteric FS.

predicting the postoperative ileus among the patients with bladder cancer, who had received radical cystectomy. METHODS: A retrospective study was performed with 223 consecutive patients with bladder cancer who had received radical cystectomy between January 2001 and May 2007. The abdominal circumference (AC), the abdominal anterior-posterior and transverse diameters (APD and TD), and intra-abdominal VFA were determined at the umbilical level by the previously reported CT scanning technique. 9)$ZDVGH¿QHGDVDQ\DUHDZLWK+RXVH¿HOGLQWHQVLW\RIEHWZHHQ DQG+8DQGPHDVXUHGXVLQJ5DSLGLDSURJUDP,Q¿QLWW6HRXO 7KH comparisons of the differences of clinico-pathological factors and the anthropometric parameters were performed between those patients with postoperative ileus and the others with non-postoperative ileus. Logistic regression analysis was used to assess the possibility of the above factors for the prediction of postoperative ileus. RESULTS: Mean age of study subject was 63.6 years and there were 194 (87%) male patients. 93 (42%) patients received orthotopic bladder substitution. The postoperative ileus occurred in 51 (23%) patients and 19 (8.5%) patients had major complications. There were no differences in sex, age, type of operations, operative time, and blood loss between those with ileus group and the others with non-ileus group. There was also no difference in pathological stage, whereas the major complications occurred higher in postoperative ileus group. When compared anthropometric parameters, there were no differences in BMI (23.3kg/m2 vs. 23.1kg/m2, p=0.709), AC (85.9cm vs. 84.2cm, p=0.199), APD (21.8cm vs. 20.9cm, p=0.100), TD (30.4cm vs. 30.1cm, p=0.560), and in VFA (115cm2 vs. 100cm2, p=0.093).

METHODS: From 1987 to 2005, a consecutive series of 900 patients underwent radical cystectomy (RC) and extended bilateral pelvic lymphadenectomy at our institution for TCC of the bladder. Of these, 900 patients, 109 (20 women, 89 men) were found to have pathological pT3a and b after undergoing surgery either for primary invasive disease (n= RULQLWLDOO\VXSHU¿FLDOEXWVXEVHTXHQWO\SURJUHVVLYHLQYDVLYHGLVHDVH Q 3ULRUWRF\VWHFWRP\PDQDJHPHQWRIWKHLQLWLDOO\VXSHU¿FLDOEXW subsequently progressive disease patients was conducted at outside institutions.
