Effect of Type 2 Diabetes Mellitus on Prognosis of Nonmetastatic Renal Cell Cancer

Purpose: We evaluated the prognostic value of type 2 diabetes mellitus (DM) in patients treated surgically for localized renal cell carcinoma (RCC). Materials and Methods: Between 1995 and 2011, 588 patients with renal tumor diagnoses were treated surgically and 492 patients with pathologically confirmed nonmetastatic RCC diagnoses were included in the study. The associations of clinical and pathologic parameters with a type 2 DM diagnosis were evaluated. Kaplan-Meier estimations for disease-specific survival (DSS) and overall survival (OS) were generated according to type 2 DM diagnosis, and the log-rank test was used to compare survival according to the variables. Results: The mean age of the patients was 56.7±12 years (range, 15 to 84 years; median, 58 years) and the mean length of follow-up was 35.9±28 months (range, 1 to 145 months; median, 34.3 months). Of the 492 patients, 62 (12.6%) had a diagnosis of DM at the time of surgery (group I) and 430 did not have DM (group II). The mean age and the incidence of clear cell RCC histological subtype were significantly higher in group I than in group II (p<0.001 and p=0.036, respectively). Although DSS and OS were lower in group I, this difference was not significant. Type 2 DM was not detected as an independent prognostic factor for DSS and OS. Conclusions: This study investigated the role and effect of DM on the prognosis of localized RCC that was treated surgically. The present study did not detect DM as an independent prognostic factor for RCC.

Purpose: To evaluate the outcomes of rigid ureterorenoscopy (URS) for renal pelvic stones (RPS) sized 1 to 2 cm and to determinethe predictive factors for the requirement for flexible URS (F-URS) when rigid URS fails. Materials and Methods: A total of 88 patients were included into the study. In 48 patients, the RPS were totally fragmented withrigid URS and F-URS was not required (group 1). In 40 patients, rigid URS was not able to access the renal pelvis or fragmentationof the stones was not completed owing to stone position or displacement and F-URS was utilized for retrograde intrarenal surgery(RIRS) (group 2). The predictive factors for F-URS requirement during RIRS for RPS were evaluated. Both groups were compared regardingage, height, sex, body mass index, stone size, stone opacity, hydronephrosis, and previous treatments. Results: The mean patient age was 48.6±16.5 years and the mean follow-period was 39±11.5 weeks. The overall stone-free rate inthe study population was 85% (75 patients). In groups 1 and 2, the overall stone-free rates were 83% (40 patients) and 87% (35 patients),respectively (p>0.05). The independent predictors of requirement for F-URS during RIRS were male gender, patient height,and higher degree of hydronephrosis. Conclusions: Rigid URS can be utilized in selected patients for the fragmentation of RPS sized 1 to 2 cm with outcomes similar tothat of F-URS. In case of failure of rigid URS, F-URS can be performed successfully in this group of patients.

Purpose: To evaluate the long-term outcomes of artificial urinary sphincter (AUS) implantation and to report the complication rates, including mechanical failure, erosion,and infection. Materials and Methods: From June 1990 to May 2011, AUS (AMS 800) implantations were performed in 56 adult males by one surgeon. Various demographic and preoperative variables, surgical variables, and postoperative outcomes, including success and complication rates with a median follow-up of 96 months, were recorded retrospectively. Results: The mean age of the patients at the time of AUS implantation was 61.8 (±14.2)years. During the follow-up period, the total complication rate was 41.1% (23 patients). The incidence of complications was significantly lower during the follow-up period after 48 months (p<0.05). Kaplan-Meier analysis revealed that 5- and 10-year failure-free rates were 50.3% and 45.2%, respectively. Conclusions: Long-term durability and functional outcomes are achievable for the AMS 800, but there are appreciable complication rates for erosion, mechanical failure, and infection of up to 30%.
