Objective: To examine the effect of warm and cold ischemia on functions of the operated kidney in cases with a normal contralateral kidney undergoing nephron sparing surgery. Methods: This study enrolled 40 patients with a normal contralateral kidney and without a renal function threatening risk factor, who were operated with NSS. The patients were randomized at admission. They were divided into 2 equal groups as warm and cold ischemia. An ice application for 10 minutes was done to cold ischemia group after clamping renal artery. Renal functions were evaluated with Technesium-99m-Dimercaptosuccinic Acid (DMSA) and serum creatinine at the preoperative and postoperative (day 1, day 15, month 6, and month 12) period. Statistical analysis was done with Mann Whitney U test, Wilcoxon Signed Rank test, and Fredman test. A p value below 0.05 was considered statistically significant. Results: There were no significant differences between the groups in terms of age, body mass index, ischemia time, tumor size, amount of hemorrhage, and procedure time. Both groups had a significantly higher DMSA uptake at the preoperative period compared with the postoperative period (postoperative day 1, day 15, month 6, and month 12) (p 0.001). However, both groups had similar DMSA uptake results at the postoperative period. Preoperative and postoperative creatinine levels were not significantly different from each other in both groups. Conclusion: Based on tumor localization, nephron sparing surgery without use of superficial cooling appears as a viable option for small renal masses.

Objective: To evaluate the long term follow-up results of the direct nipple ureteroneocystostomy technique. Materials and Methods: We studied a total of 16 patients (19 renal units) who underwent direct nipple ureteroneocystostomy. The mean age was 43 years and 3 patients had bilateral disease. In five units the ureters had been ligated during gynecological surgery, 11 renal units were obstructive and three units were reflexive megaureters. The ureters were spatulated for about 2 cm and folded back. Nipples 2 to 2.5 cm long were prepared. In two cases the ureters were thin-walled (2 mm or less) and they were not spatulated but folded back onto themselves. In one case the ureter could not be everted since it had a thick and fibrotic wall. The distal 2 to 2.5 cm segment of this ureter was directly inserted in to the bladder. Postoperative follow-up was at 3 month intervals for the first year at 6 month intervals for 2 - 3 years and yearly thereafter. At the time of follow-up serum creatinine, urine culture, ultrasound, intravenous urography, voiding cystoureterography, nuclear renal scintigraphy and cystometric evaluations were performed. The functions of 11 and 15 renal units were evaluated scintigraphically and stereologically, respectively, in the both preoperative and postoperative first year follow-up. The Wilcoxon Signed Ranks test was used for statistical evaluation and p < 0.05 was considered statistically significant. Results: Mean follow-up was 49 months. Three renal units had Grade III reflux (two of them during voiding) and one unit had Grade IV reflux. At follow-up this patient developed in the ureteral stricture. No patients had urinary tract infection, pyelonephritis or ureteral stricture follow-up period. Between the preoperative and postoperative first year, there was an increase in postoperative split renal function based on renal scintigraphy but this difference was not statistically significant. The stereologically calculated decrease in pelvicalic
