    Objective: To evaluate the feasibility and renoprotective effect of off-clamp partial nephrectomy (PN) by renal scoring systems. Methods: After approval of the local ethics committee, the radiological and clinical data of patients with renal masses who underwent PN between January 2012 and January 2017 were evaluated in two university hospitals. Total 132 patients who underwent open surgery and off-clamp technique were included. All patients underwent contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) preoperatively. Preoperative demographic data, estimated glomerular filtration rate (e-GFR) and hematocrit changes, operation time, tumor volume and hospitalization time from patients were evaluated separately and statistically for each of the three scoring systems. Results: Our study consisted of 132 patients with a mean age of 53.9 +/- 113.9 with 69 male and 63 female. Statistically significant difference between the risk groups in RENAL and PADUA scoring were found according to tumor T stage and tumor volume (p < 0.005). Statistically significant difference was only found between risk groups of RENAL scoring system in e-GFR reduction (p<0.05). There was no statistically significant difference between the groups in the complications of all three classification systems (p > 0.005). Conclusions: In our study, all three scoring sytem successfully predicted the surgical complexity ve surgical outcomes and our results indicate that off-clamp PN has similar success and complications rates when compared to the literature. The off-clamp PN must be kept in mind to maintain postoperative renal functions eligible patients. (C) 2018 Asian Surgical Association and Taiwan Robotic Surgery Association.

    Dose routine intraoperative Double J stent insertion avoid urine leakage after open partial nephrectomy?
    (PAGEPRESS PUBL, 2022-01-01) Bosnali, Efe; Dillioglugil, Ozdal; Teke, Kerem; Yilmaz, Hasan; Bayrak, Busra Yaprak; Uslubas, Ali Kemal; Avci, Ibrahim Erkut; Argun, Omer Burak; Kara, Onder
    Objective: To evaluate the impact of Double stent (DJS) insertion during open partial nephrectomy (OPN) on postoperative prolonged urinary leakage. Materials and methods: A retrospective study was made in consecutive cases of OPN performed between 2002 and 2020 for localized kidney tumors at our tertiary center. Urinary leakage was defined as drainage > 72 hours after surgery by biochemical analysis consistent with urine or radiographic evidence of urine leakage. The patients were divided into two groups according to intraoperative DJS placement, and compared regarding clinicopathologic characteristics, perioperative and postoperative outcomes. Univariate and multivariate logistic regression analyses were performed to determine the factors associated with urinary leakage after the operation. Results: Review of records identified 182 patients who were included in the study. In 73 (40\%) patients PN was performed without insertion of a DJS. Thus, 109 (60\%) of patients had a DJS inserted. Apart from higher preoperative eGFR values among patients with DJS (96.6 vs. 94.3 mL/min/1.73 m(2)
