INTRODUCTION: For the treatment of patients with end-stage renal disease, kidney transplantation is preferred to renal replacement modalities such as hemodialysis and peritoneal dialysis. Although open surgery remains the gold standard, minimally invasive approaches have recently been applied in transplant kidney surgery. Despite growing enthusiasm and potential benefits of robotic kidney transplant, many aspects of this novel technique remain controversial. Aim of this study was to analyze the current status and future developments in robotic-assisted surgery for kidney transplantation...

INTRODUCTION: Laparoscopic living donor nephrectomy is the standard of care at high-volume renal transplant centres, with benefits over the open approach well-documented in the literature. Herein, we present a retrospective analysis of our single-institution donor nephrectomy series comparing the mini-open donor nephrectomy (mini-ODN) to the laparoscopic donor nephrectomy (LDN) with regards to operative, donor, and recipient outcomes. METHODS: From 2007-2011, there were 89 cases of mini-ODN, at which point our centre transitioned to LDN; 94 cases were performed from 2011-2014...

PURPOSE: Skilled assistant surgeon is presumed necessary during robotic assisted partial nephrectomy (RAPN) to minimize warm ischemia time (WIT) and to facilitate complex renorrhaphy. Studies observing impact of resident participation have focused on robotic prostatectomies, showing no impact on core surgical outcomes. Herein, we evaluated the level of experience of the bedside assistant and its impact on peri-operative outcomes in RAPN. METHODS: All RAPN cases in our healthcare system from January 2011 to December 2013 were retrospectively reviewed...

BACKGROUND: Nephron sparing surgery (NSS) is well established as the standard of care for most surgical small renal tumors when technically feasible. While the majority of sporadic renal tumors are solitary, multifocal tumors have been reported in 5.4% to 25% of patients with tumors smaller than 5cm. We present a video where we approach, through laparoscopy, four tumors on the same kidney. CASE STUDY: Male, 58y, went through a routine abdominal ultrasound which showed a 5cm left kidney nodule...

Warm renal ischemia performed during partial nephrectomy has been found to be associated with kidney disease. Since endogenous ouabain (EO) is a neuro-endocrine hormone involved in renal damage, we evaluated the role of EO in renal ischemia-reperfusion injury (IRI). We measured plasma and renal EO variations and markers of glomerular and tubular damage (nephrin, KIM-1, Kidney-Injury-Molecule-1, α1 Na-K ATPase) and the protective effect of the ouabain inhibitor, rostafuroxin. We studied five groups of rats: (1) normal; (2) infused for eight weeks with ouabain (30 µg/kg/day, OHR) or (3) saline; (4) ouabain; or (5) saline-infused rats orally treated with 100 µg/kg/day rostafuroxin for four weeks...

Laparoscopic donor nephrectomy (LDN) can be performed via either transperitoneal or retroperitoneal approach. Very few studies have been carried out till now, comparing immunologic and inflammatory responses in donors after these two approaches. This is a prospective observational study. Selection of approach was decided by the operating surgeon. All patients underwent peripheral venous blood sampling preoperatively and 24 h postoperatively for the measurement of C-reactive protein (CRP), interleukein-6 (IL-6), total leukocyte count (TLC), blood urea nitrogen (BUN), and serum creatinine (SCr)...

OBJECTIVES: The aim of this study was to investigate the clinical usefulness for prediction of outcome of laparoscopic partial nephrectomy (LPN) using the R.E.N.A.L nephrometry scoring system (RNS) and centrality index score (C-index). MATERIALS AND METHODS: We retrospectively reviewed 64 patients who underwent LPN from 2010 to 2014 in our institution. The RNS and C-index scores were assigned according to the described protocols for their systems. The relationships between the patients' scores before surgery and the outcomes of LPN, warm ischemia time (WIT), operative time (ORT), estimated blood loss (EBL), and percent change in estimated glomerular filtration rate (eGFR) were analyzed retrospectively...

Allopurinol is a well-known antioxidant that protects tissue against ischemia and reperfusion injury, blocking purine catabolism, and possibly reducing TNF-α and other cytokines. It also plays a significant role in reducing the inflammatory processes by inhibiting chemotaxis and other inflammatory mediators. The objective of this study was to define the role of allopurinol regarding kidney ischemic injury particularly as to its effect on inflammatory molecules such as TNF-α, IL-1β, and IL-6 response. One hundred and twenty five rats were subjected to warm renal ischemia...

Hypothermic preservation is known to cause renal graft injury, especially in donation after circulatory death (DCD) kidney transplantation. We investigated the impact of cold storage (SCS) versus short periods of normothermic ex vivo kidney perfusion (NEVKP) after SCS versus prolonged, continuous NEVKP with near avoidance of SCS on kidney function after transplantation. Following 30 min of warm ischemia, kidneys were removed from 30-kg Yorkshire pigs and preserved for 16 h with (A) 16 h SCS, (B) 15 h SCS + 1 h NEVKP, (C) 8 h SCS + 8 h NEVKP, and (D) 16 h NEVKP...

REVIEW
Jihad H Kaouk, Ercan Malkoç
Nephron sparing surgery (NSS) is the gold standard treatment option for patients with a solitary kidney in order to preserve renal function. Open partial nephrectomy (OPN) has been long considered the standard care for NSS. Robotic partial nephrectomy (RPN) is being gradually used more commonly even for solitary kidney and complex tumors. There was no difference between RPN and OPN regarding the rate of intraoperative-postoperative complications and positive surgical margin (PSM) (RPN: 7.5%, OPN: 8%) for patients with solitary kidney who underwent partial nephrectomy for small renal masses...
