Eur Urol Suppl 2010;9(6):590 and stented and the other hand between intravesical Leadbetter-Politano and extravesical Lich-Gregoir (L-G) procedures. No technique has been convincingly proven to be superior to the other. Most of urological complications involve uretero- vesical anastomosis. These include stenosis, leak and bleeding. We describe our experience with surgical technique of modified Y-V Lich-Gregoir UCN and emphasize their extremly low complications rate in our series. Material & Methods: Between 30th January 1996 – 1st June 2010 at our institution 294 kidney transplantations were performed. The mean age of transplant recepients was 37, and male to female ratio of 2:1. In 1 patient we performed Taguchi or „one stitch“ technique of UCN, 2 recepients underwent L-G technique with detrusorraphy, and in 291 recepients we performed modified Y-V L-G UCN with two paralel incisions. The modification of the Lich-Gregoir technique we used consist of two paralel detrusor muscle incisions on anterior site of bladder and creation of detrusor bridge. First incision of the bladder wall to the mucosa is above and shorter then second. Second lower incision is longer. Detrusor bridge is usually three times longer then thickness of the ureter. After mucosal opening on the lower incision of detrusor we made an inverted Y on bladder mucosa and forming a V flap which was anastomosed with spatulated ureter after his wriggling under detrusor bridge. The detrusor muscle was closed over the ureter. All patients were stented with 6-Fr polyurethane double J-stent. The Foley catheter removed between 5-10 days. Results: In our study we had three serious complications. In recepient who had Taguchi „one stich“ UCN developed long tubular ureteral stenosis up to ureteropyelic junction. In this case we successfully anastomsed pyelon of transplanted kidney with native ureter. One patient who had standard L-G UCN developed stenosis ureterovesical anastomosis what we resolved with reUCN. In third patient the other one with standard L-G UCN we diagnosed large urinoma with consecutive infection and necrosis of complete ureter up to UPJ. He was reoperated and performed pyelovesical anastomosis with Boari flap technique. In 4 (1,3%) recepients with modified Y-V Lich-Gregoir UCN we had urinary leakage what we were treated conservatively with delayed removal of double-J stent and prolonged bladder catheterisation. Conclusions: The technique of extravesical ureteral implantation is successful, simple to perform, reproducible and associated with low morbidity. The complication rate of uretero-vesical anastomosis in our series is 1,3%. The several advantages of modified Y-V Lich-Gregoir UCN are: less operative time, ability to use short ureters, avoidance of a separate cystotomy and shortened Foley catheter drainage.

The aim of this retrospective study was to evidence the epidemiologic data of kidney tumors in Albania. Material & Methods: The retrospective study was conducted during the period January 1995- December 2009. There are included 816 patients aged 57 ± 10 years old, diagnosed with kidney tumor. The male-female ratio was 71 % / 29 %. Results: The clinical signs and symptoms in our seria were: hematuria 72.3%, flank pain 48.7 %, paraneoplasic syndrome 13.4 %, anaemia 20 %, weight loss 24.5 %, metastasis 1.2 %. The main diagnostic approach was CT 84.4 %, MRI 33.8%, ultrasonography 82.3 %, UIV 43 % and renal angiography 3.2 %. In our seria, regarding risk factors, smoking was faced in 37 %, hypertension 14.5 %, obesity and diabetes in 6.7 % of the patients. The majority of cases (58 %) were Elbasan inhabitants. Conclusions: We think that smoking, obesity and diabetes and of course ambient factors are the main risk factors related to kidney tumors in Albania. S132 PROGNOSTIC SIGNIFICANCE OF VEGF, KI–67 AND FAS EXPRESSION IN RENAL CELL CARCINOMA Duran E. 1 , Secinti I.E. 2 , Canda A.E. 1 , Kandemir O. 2 , Balbay M.D. 1 1 Ankara Atatürk Training and Research Hospital, Dept. of 1st Urology, Ankara, Turkey, 2 Ankara Atatürk Training and Research Hospital, Dept. of Pathology, Ankara, Turkey Introduction & Objectives: The role of the immunohistochemical expression of molecular markers including vascular endothelial growth factor (VEGF), Ki-67 and fatty acid synthase (FAS) were analyzed in order to find out their possible effect on prognosis, therapy outcomes, clinical and pathological parameters of patients with renal cell carcinoma (RCC). Material & Methods: VEGF, Ki–67 and FAS expression were evaluated immunohistochemically in 122 patients with RCC and their relationship between various clinicopathological parameters were analyzed in patients who underwent partial or radical nephrectomy due to renal mass between 2004–2009 in our Introduction & Objectives: Bilateral renal cell carcinomas (bRCC) account approximately 4% of all renal tumors. We report on the surgical management, histopathologic results and follow up of 5 patients with bRCC. Material & Methods: For the period of 2 years (2008 - 2009) we had 5 (2.05%) cases of bilateral, non-familial synchronous RCC. This is a relatively low number of all RCC cases, compared to the number of patients (243) who passed radical nephrectomy for RCC in our department for the same period of time. All patients were men, average 60.6 years old (range 40-73 ). In all cases one stage surgery – chevron incision and nephrectomy of the kidney bearing the larger tumor, and partitial neprherctomy on the other side was done. Results: In all cases we did left nephrectomy, due to larger tumor burden on that side, and partitial nephrectomy on the right side. At the final pathological report clear cell carcinoma was found bilaterally in four cases, and clear cell carcinoma mixed with areas of papillary carcinoma in the left kidney and clear cell carcinoma in the right in one case. One patient had caval tumor thrombus ascending to the atrium. We did nephrectomy and thrombectomy under extracorporeal blood circulation, in cooperation with cardiosurgery team. The same patient had pulmonary metastases at the time of diagnosis. In all other three cases we didn’t observe any lymphatic or distant metastases in the time of surgery. The average operative time was 3,5 hours, the average blood loss was 730ml., and the average postoperative hospital stay was 10.7 days. The creatinine levels postoperatively ranged between 138 – 174 mmol/l (mean 148.4). None of the patients needed any postoperative dialysis. One patient died on the 9 th day due to pulmonary embolism. In the other four cases we didn’t observe any excessive intra or postoperative complications. All four patients had close follow up in our department for the 9 - 21 months (average 16 months). Two patients passed immunotherapy with IFN alfa and sunitinib due to metastatic disease, and another two does not have any sign of metastatic disease, and are in good performance status on follow up. Conclusions: One stage surgery for bilateral synchronous RCC is method of choice in our department for high risk cases, despite it is aggressive and bears high risk potential of postoperative complications. For these reason our opinion is that such operations must be performed only by experienced surgeons in large urological centers. S129 ARE VALUES DETERMINED BY DMSA AND DTPA SCINTIGRAPHY COMPARABLE FOR EVALUATION OF RENAL FUNCTION? Zekey F. 1 , Ateş F. 1 , Soydan H. 1 , Şen B. 1 , Urgan M. 2 , Şenkul T. 1 1 GATA Haydarpasa Training Hospital, Dept. of Urology, Istanbul, Turkey, 2 GATA Haydarpasa Training Hospital, Dept. of Nuclear Medicine, Istanbul, Turkey Introduction & Objectives: Aim of this study was to compare DMSA(dimercapto succinic acid) and DTPA (diethyl triamine penta acetic acid) renal scintigraphy results for evaluate differentiated renal function examination. Material & Methods: Patients, whoose admitted to outpatient clinic and diagnosed kidney stone underwent ESWL between 2007 and 2009. They were evaluated with both scintigraphy methods DMSA and DTPA before and after ESWL. Contribution to the renal function of each kidney was calculated by both methods. Before and after ESWL differentiated renal functions results were compared and correlation between them was examined. Statistics was done with SPSS version 16.0, Wilcoxon test. Results: Fourty patients was included into the study. Twenty five patients had right and 15 had left kidney stones. Mean age, height and weight was 23 (19-38)years, 172 cm (150-190) and 72 kg (54-100) respectively. Before treatment, right and left differentiated renal function with DMSA was 50% (32-66) and 50% (34-68), with DTPA was 50%(30-63) and 50%(37-70). After ESWL right and left differentiated renal function with DMSA was 51% (32-67) and 49% (33-68), with DTPA was 49%(31-64) and 51%(36-69) respectively. Correlations of two scintigraphy results were highly significant before and after treatment (p<0.001). Before treatment evaluation, there wasn’t any difference about two scintigraphy results (DMSA and DTPA) between contribution to total renal function of right and left kidney (p=0.258 and p=0.296 respectively). After treatment, contribution of total renal function of each kidney was calculated with also DMSA and DTPA, results were statistically different (p=0.048 for right kidney and p=0.048 for left kidney). Looking at the rate of change within group, results were also similar with both scintigraphy methods. Conclusions: Although DMSA have been used for calculation of renal function, our results was showed that DMSA and DTPA results are parallel but after any intervention like SWL, two scintigraphy results might be different. Therefore, after intervention, it is understood that the two methods must not be used interchangeably for differentiated renal function evaluation.
