INTRODUCTION: The renal nephrometry scoring (RNS) system enables prediction the feasibility of nephron-sparing surgery (NSS) in renal masses. There is insufficient data regarding the outcome of robot-assisted NSS in tumors with RNS ≥10. We reviewed the trifecta outcomes of patients undergoing robotic NSS with high RNS and compare it with tumors of low and intermediate RNS. MATERIALS AND METHODS: Our prospectively maintained data of all robot-assisted NSS were reviewed, and those with RNS of ≥10 were identified...

According to the World Health Organization, pathologies associated with ischemia/reperfusion occupy the leading position in the structure of mortality. The efficiency of localized kidney cancer surgery is limited by the damaging effects of prolonged warm ischemia and reperfusion. Ischemia/reperfusion damage to renal tissue may be related to changes in the expression profiles of pro- and antiapoptotic genes. Here, we have presented the longitudinal expression profiles of apoptosis-related genes in tissues of left and right (intact) kidneys of male rats exposed to unilateral ischemia followed by reperfusion...

BACKGROUND: Robot-assisted laparoscopic partial nephrectomy (RLPN) is an emerging technique for treating small renal masses. Although RLPN has many advantages, ischemic kidney injury is inevitable during renal artery clamping. The overall incidence of acute kidney injury (AKI) after partial nephrectomy has been reported to be up to 39%. Moreover, effective pharmacological protection against AKI after partial nephrectomy has not yet been demonstrated. Ulinastatin has been shown to protect the kidney from ischemia/reperfusion injury via its anti-inflammatory and anti-oxidant activities...

Purpose: To investigate the glomerular number after different warm ischemia times. Methods: Thirty two pigs were assigned into four groups. Three groups (G10, G20, and G30) were treated with 10, 20, and 30 minutes of left renal warm ischemia. The sham group underwent the same surgery without renal ischemia. The animals were euthanized after 3 weeks, and the kidneys were collected. Right kidneys were used as controls. The kidney weight, volume, cortical-medullar ratio, glomerular volumetric density, volume-weighted mean glomerular volume, and the total number of glomeruli per kidney were obtained...

Deficiency in the membrane-bound complement regulators CD55 and CD59 exacerbates renal ischemia-reperfusion injury (IRI) in mouse models, but the effect of increasing CD55 and CD59 activity has not been examined. In this study, we investigated the impact of overexpression of human (h) CD55 ± hCD59 or treatment with soluble rhCD55 in a mouse model of renal IRI. Unilaterally nephrectomised mice were subjected to 18 (mild IRI) or 22 min (moderate IRI) warm renal ischemia, and analyzed 24 h after reperfusion for renal function (serum creatinine and urea), complement deposition (C3b/c and C9), and infiltration of neutrophils and macrophages...

Pigs represent a desirable animal model for the study of rejection in kidney transplantation with inbred Yucatan miniature swine (YMS) the most commonly studied strain due to well defined swine leukocyte antigen (SLA) genotypes. However, limitations to YMS may include cost and availability. Outbred Yorkshire pigs are widely available and significantly cheaper than YMS. Recent advances in SLA genotyping have allowed its application to outbred strains. On this basis, we theorized that Yorkshire pigs would be a viable alternative to YMS for the study of rejection in kidney transplantation...
