BACKGROUND: Despite better renal function following nephron-sparing surgery (NSS) relative to radical nephrectomy (RN), there is no consensus with respect to the long-term sequelae associated with surgery. OBJECTIVE: To investigate the effect of surgery and the temporal pattern of two different cardiovascular event (CVe) categories after NSS versus RN. DESIGN, SETTING, AND PARTICIPANTS: We collected data of 898 patients with cT1-2 N0 M0 renal mass and no history of CVe treated with NSS versus RN...

Our recently reported phase III trial demonstrated that patients undergoing nephron-sparing surgery (NSS) with an estimated glomerular filtration rate (eGFR) of ≥45 ml/min/1.73 m2 who received mannitol had no improvement in renal function at 6 mo compared with those who received placebo. Some authors have suggested that benefit is restricted to subgroups, such as those with comorbidities. We assessed whether preoperative eGFR, or other patient and surgical factors modified the effect of mannitol on postoperative outcomes at 6 mo and with extended follow-up...

Our understanding of the potential impact of ischemia time on renal function during nephron-sparing surgery (NSS) is based on decades of low-quality evidence. Recent studies have shown that the baseline quality of the renal parenchyma and the quantity of parenchyma remaining, rather than duration of ischemia, are more important in predicting renal functional recovery. A prospective clinical trial evaluating actual renal parenchyma under clamp conditions during NSS showed minimal structural and functional changes that were reversible and were not associated with duration of ischemia...

BACKGROUND: One major objective of currently available morphometric scores (MS) for renal masses, i.e., R.E.N.A.L., PADUA classification, Centrality-Index, is the prediction of type of surgery (nephron-sparin surgery [NSS] or radical nephrectomy [RN]). METHODS: Based on a prospective study protocol, various MS were assigned and calculated for 108 patients undergoing surgical treatment for renal masses at a single academic center. MS calculation was based on preoperative computed-tomography or magnet-resonance-imaging and performed by two independent readers blinded for surgical approach and outcome...

Renal ischaemia research has shown an increase in renal damage proportional to ischaemic time. Therefore, we assessed the importance of renal ischaemic times for warm and cold ischaemia approaches, and explored the different surgical techniques that can help to minimise renal ischaemia in robot-assisted partial nephrectomy (RAPN). Minimising renal ischaemia during nephron-sparing surgery (NSS) is a key factor in preserving postoperative renal function. Current data support a safe warm ischaemia time (WIT) of ≤25 min and cold ischaemic time of ≤35 min, resulting in no significant deterioration in renal function...

Results: A total of 47 patients(31 male and 16 female) were enrolled in our study...

In recent years the incidence of small renal carcinoma is increasing, and nephron sparing surgery(NSS) becomes the mainstream to treat it. NSS is considered based on comprehensive analysis: the imaging examination, systemic evaluation of the patients, and the indications of NSS. There are three common surgical approaches: intraperitoneal approach, retroperitoneal approach and the joint approach. It is recommended to do intraoperative frozen pathology. If the edge is positive, it is better to cut a deeper layer of the tissue around the renal tumor or transform to radical nephrectomy...

PURPOSE: To identify variations in renal function and histology between Caucasian Americans (CA) and African Americans (AA) undergoing robotic nephron-sparing surgery (NSS).
