Objective: The RENAL nephrometry scoring system charac-terizes tumors according to their size, growth pattern, loca-tion and nearness to the renal sinus or collecting system. The current study alms to evaluate the RENAL nephrometry scor-ing system in adopting nephron-sparing surgery (NSS) for cTI renal cancer. Methods: Clinicopathological data of 200 con-secutive patients who had undergone radical nephrectomy (RN) or NSS for clinical stage T1 renal cell cancer at our single institution during 2005-2009 were investigated retrospec-tively. Results: Of 200 patients, 103 were scheduled for RN, whereas 97 were planned to undergo NSS, 9 of whom actu-ally underwent RN. Those who were planned to undergo NSS were youngerand had smaller tumors (p<0.001).The median RENAL score was significantly lower among those who were originally assigned to NSS (5, range 4-10) versus RN (8, range 4-11) (p < 0.001). Three months after surgery, the renal func-tion of patients who had been scheduled for NSS was signifi-cantly better than in those treated by RN (p < 0.001). Conclu-sions: This study suggests that the RENAL nephrometry scor-ing system is a useful tool in adopting NSS for cTI renal cancer and that objective decision-making for NSS was possible.

Objectives: To analyze the incidence and predictors of deep vein thrombosis (DVT) in patients with elevated D-dimer prior to surgery for urologic malignancy. Methods: Between January 2015 and September 2017, 987 consecutive patients underwent surgery for urologic malignancy under general anesthesia in our institution. Of these, 191 patients underwent preoperative venous ultrasonography of the lower extremities for DVT due to elevated D-dimer. We analyzed the incidence and predictors of DVT in these patients. Results: The median age was 69 years. DVT was detected in 18% of patients (35/191). Multivariate analysis showed that the primary site of urologic malignancy (p < 0.01) and older age (p < 0.01) were independent predictors of DVT. Patients with bladder cancer had the highest incidence of DVT. When bladder cancer and age of 70 or older were defined as predictors for DVT, the incidence of DVT in zero, 1, and 2 predictors was 3.4% (3/89), 29% (22/77), and 44% (11/25), respectively. Conclusions: DVT was found in 18% of patients with elevated D-dimer prior to surgery for urologic malignancy. Bladder cancer patients and older patients in whom D-dimer has been elevated should undergo careful early examination for DVT. [ABSTRACT FROM AUTHOR]
