Introduction: We investigate the clinical significance of the R.E.N.A.L. nephrometry score for renal neoplasm following open partial nephrectomy (PN) under cold ischemia.Methods: A retrospective analysis was conducted using clinical data of 98 consecutive patients with clear cell renal cell carcinoma who underwent open PN by a single surgeon from December 2000 to September 2012. Tumour complexity was stratified into 3 categories: low (4-6), moderate (7-9) and high (10-12) complexity. Perioperative outcomes, such as complications, cold ischemic time, estimated blood loss and renal function, were analyzed according to the complexity by NS. Complications were stratified using the Clavien-Dindo classification system.Results: Tumour complexity according to nephrometry score was assessed as low in 16 (16.3%), moderate in 48 (49.0%) and high in 34 (34.7%). The median cold ischemic time did not differ significantly among the 3 groups (36.0 minutes in low-, 40 minutes in moderate- and 43 minutes in the high-complexity group, p = 0.421). Total complications did not differ significantly (2 (2.0%) in low, 4 (4.1%) in moderate and 4 (4.1%) in high, p = 0.984). Each Grade 3 complication occurred in the moderate (urine leakage) and high groups (lymphocele). Postoperative renal functional outcomes were similar among the groups (p = 0.729). Only mean estimated blood loss was significantly different with nephrometry score (p = 0.049).Conclusions: The nephrometry score, as used in an open PN series under cold ischemia, was not significantly associated with perioperative outcomes (i.e., ischemia time, complications, renal functional preservation).

Objective. To evaluate the feasibility of an internal suspension technique in retroperitoneal laparoscopic partial nephrectomy for the management of renal ventral tumors. Methods. Between January 2013 and July 2016, a total of 145 patients underwent retroperitoneal laparoscopic partial nephrectomy with or without internal suspension technique. For patients who underwent internal suspension technique, the surgeons preserved the external fat of the renal tumor as a suspension traction measure when separating the kidney. Propensity score matching (PSM) was performed according to age, gender, body mass index, tumor size, tumor location, and RENAL nephrometry score. Patient characteristics and intraoperative and postoperative outcomes were compared between the groups. Results. After PSM, 32 patients treated with the internal suspension technique were compared with 32 cases treated without such technique. Baseline characteristics were statistically similar for the cohorts. The use of our new technique resulted in shorter warm ischemia time (WIT: 15.0 versus 19.0 minutes, P=.002) and tumor resection time (4.0 versus 7.5 minutes, P<0.001). The rate of WIT >25 minutes decreased (6.3% versus 25%, P=.04) and the trifecta outcomes were significantly improved (87.5% versus 62.5%, P=.02). Conclusion. Internal suspension technique is a feasible and safe procedure in retroperitoneal laparoscopic partial nephrectomy for renal ventral tumors.

Background: The R.E.N.A.L.(radius, exophytic/endophytic properties, nearness of tumor to the collecting systemor sinus in mm, anterior/posterior location relative to polar lines) nephrometry scoring system was recently introduced as an objective reproducible means to describe salient renal tumor anatomy. Objective of this study is to evaluate the role of R.E.N.A.L. Nephrometry score in predicting tumor histology and grade.  Methods: It is a prospective study carried out in Lilawati Hospital and Research Centre, a tertiary care centre consisting of 40 patients including male and female who had T1 renal mass.  Preoperative R.E.N.A.L. Nephrometry scoring  done for every patient and after treatment (Open Partial Nephrectomy, Laproscopic partial Nephrectomy, Radical Nephrectomy)  tumor sent for histopathology to predict tumor histology and grade for solid renal mass. Results: Clear cell histology also increased with R.E.N.A.L score, from 2/6 (33.3%) in patients with low R.E.N.A.L scores ( 4–6) up to 15/17 (88.24%) for patients with high R.E.N.A.L scores( 10–12) . Conversely, the probability of the potentially more indolent papillary RCC decreased with increasing lesion complexity (from 66.67% in low score to 11.76% in moderate score).The Fuhrman grade is an important prognostic indicator for RCCs. In our study Fuhrman grade 1 tumours represented 4/40 (66.7%) low and 2(13%)high- complexity lesions . Conversely, there is no grade 3 lesion in low score (0.0%) compared with 5/40 (33.3%%) moderate complexity lesions, respectively showing more the nephrometry score higher will be Fuhrman grade. Conclusions: Proportion with 
clear cell histology also increases with R.E.N.A.L score and the probability of the potentially more indolent papillary RCC decreased with increasing lesion complexity. The Fuhrman grade also increases with increase in nephrometry score Keywords:  R.E.N.A.L  Nephrometry score, Fuhrman grade, Tumor histology

Background Comparable oncological outcomes have been seen after surgical nephrectomy and thermal ablation of renal tumors recently. However, periprocedural outcome needs to be assessed for aiding treatment decision. Purpose To compare efficacy rates and periprocedural outcome (technical success, session time, hospitalization time, and complications) after renal tumor treatment with laparoscopic partial nephrectomy (LPN) or radiofrequency ablation (RFA). Material and Methods The initial experience with 49 (treated with LPN) and 84 (treated with RFA) consecutive patients for a single renal tumor (diameter ≤ 5 cm, limited to the kidney) during 2007–2014 was evaluated. Patient and tumor characteristics, efficacy rates, and periprocedural outcome were collected retrospectively. The stratified Mantel Haenzel and Van Elteren tests, adjusted for tumor complexity (with the modified R.E.N.A.L nephrometry score [m-RNS]), were used to assess differences in treatment outcomes. Results Primary efficacy rate was 98% for LPN and 85.7% for RFA; secondary efficacy rate was 93.9% for LPN and 95.2% for RFA; and technical success rate was 87.8% for LPN and 100% for RFA. Median session (m-RNS adjusted P < 0.001; LPN 215 min, RFA 137 min) and median hospitalization time were longer after LPN (m-RNS adjusted P < 0.001; LPN 5 days, RFA 2 days). Side effects were uncommon (LPN 2%, RFA 4.8%). Complications were more frequent after LPN (m-RNS adjusted P < 0.001; LPN 42.9%, RFA 10.7%). Conclusion Both methods achieved equivalent secondary efficacy rates. RFA included several treatment sessions, but session and hospitalization times were shorter, and complications were less frequent than for LPN. The differences remained after adjustment for renal tumor complexity.
