Quercetin as a nephroprotector after warm ischemia: histomorphometric evaluation in a rodent model

Int. braz. j. urol; 47 (4), 2021
ABSTRACT Purpose: To quantitatively evaluate the possible long-term protective effects of quercetin during renal warm ischemia. Materials and Methods: Male rats were allocated into 4 groups: sham (S), sham quercetin (SQ), ischemia (I), and ischemia quercetin (IQ). Groups SQ and IQ received quercetin (5...

The preoperative stratification of patients based on renal scan data is unable to predict the functional outcome after partial nephrectomy

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Introduction: eGFR-categories are used to predict functional outcome after partial nephrectomy (PN); no study categorized patients according to preoperative renal scan (RS) data. Aim of the study was to evaluate if stratification of patients according to RS is a reliable method to predict minor...

Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (5), 2018
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm isc...

Laparoscopic donor nephrectomy in unusual venous anatomy - donor and recepient implications

Int. braz. j. urol; 43 (4), 2017
ABSTRACT Objectives Laparoscopic donor nephrectomy is now a commonly performed procedure in most of renal transplantation centers. However, the suitability of laparoscopy for donors with abnormal venous anatomy is still a subject of debate. Materials and methods Between August 2007 and August 2014, 2...

The relationship between renal warm ischemia time and glomerular loss. An experimental study in a pig model

Acta cir. bras; 32 (5), 2017
Abstract 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 r...

Open partial nephrectomy for entirely intraparenchymal tumors: a matched case-control study of oncologic outcome and complication rate

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Purpose To compare the oncologic and clinical outcomes for open partial nephrectomy (OPN) performed in patients with entirely intraparenchymal tumors versus case-matched controls, with exophytic lesions. Material and methods Patients having undergone OPN between 2007 and 2012 were investigat...

Glomerular loss after arteriovenous and arterial clamping for renal warm ischemia in a swine model

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To evaluate the glomerular loss after arteriovenous or arterial warm ischemia in a swine model. METHODS: Twenty four pigs were divided into Group Sham (submitted to all surgical steps except the renal ischemia), Group AV (submitted to 30 minutes of warm ischemia by arteriovenous clamp...

Functional and oncologic outcomes after nephron-sparing surgery in a solitary kidney: 10 years of experience

Int. braz. j. urol; 42 (2), 2016
ABSTRACT Objectives: To evaluate functional and oncologic outcomes of partial nephrectomy (PN) in patients with a solitary kidney. Materials and Methods: A retrospective analysis of patients with a solitary kidney undergoing nephron-sparing surgery between March 2003 and March 2013 was performed. GFR w...
