Introduction In patients with localised renal cell carcinoma, the only curative treatment option is surgical tumour excision. Current national and European guidelines recommend partial nephrectomy in the form of an open or minimally-invasive procedure in case of small tumours. The aim of this study was to examine the use of radical (RN) or partial (PN) nephrectomy performed as open or minimally-invasive procedures in patients with pT1 /pT2 renal cell carcinoma at a tertiary referral centre. Patients and Methods This retrospective study included a total of 758 patients with localised renal cell carcinoma (pT1/pT2), who underwent PN or RN between 01/2008 and 10/2014...

INTRODUCTION: Super-selective clamping of tumor-specific segmental arteries was developed to eliminate ischemia of the remnant kidney while limiting hemorrhage during partial nephrectomy. The objective is to evaluate the benefice of super-selective clamping on renal functional outcome, compared to early-unclamping of the renal artery. MATERIALS AND METHODS: From March 2015 to July 2016, data from 30 patients undergoing super-selective robot-assisted PN (RAPN) for a solitary tumor by a single surgeon were prospectively collected...

INTRODUCTION AND OBJECTIVES: In recent years, there has been a shift to minimally invasive partial nephrectomy (MIPN) with the dissemination of robotic-assisted technology. However, contemporary data on the comparative morbidity of open PN and MIPN are lacking. We therefore evaluated the perioperative morbidity of MIPN and OPN using a contemporary national cohort. METHODS: We identified 13,658 patients aged 18-89 who underwent PN from 2010-2015 in the National Surgical Quality Improvement Program (NSQIP) database, of whom 9,018 (66...

BACKGROUND: Recent studies have suggested that the use of robotic surgery for prostatectomy has been increasing, but characterization of the diffusion of robotic surgery in other procedures has not been available. METHODS: Data were analysed for the years 2006-2014 using hospital episode statistics (HES), a database of all admissions to National Health Service (NHS) hospitals in England. OPCS codes were used to determine the annual number of prostatectomy, partial nephrectomy, and total abdominal hysterectomy procedures...

OBJECTIVE: To assess renal function in the operated kidney at different time points post partial nephrectomy (PN) and establish the time in which optimal recovery occurs. Recovery of renal function post-PN has received significant attention. However, the optimal time to determine full recovery has not been clearly established. METHODS: Renal function following minimally invasive (laparoscopic and robotic) PNs performed between 2002 and 2015 was reviewed. Patients included in this study had renal function assessed pre-operatively as well as 3 days, 6-12 weeks, and 1 year post-PN, using a combination of estimated glomerular filtration rate (eGFR) from serum creatinine and relative renal uptake (RRU) from Tc99m-MAG3 renal scintigraphy...

BACKGROUND: Off-clamp robot-assisted partial nephrectomy (RAPN) is associated with increased intraoperative blood loss compared with on-clamp technique. Our aim was to demonstrate our surgical technique and to determine which tumors are ideally suited for this technique. METHODS: Sixty-two patients who underwent off-clamp RAPN for renal tumor between 2006 and 2016 were retrospectively analyzed. Increased estimated blood loss (EBL) volume was defined as more than 75 percentile...

PURPOSE: To examine the perioperative outcomes following robot-assisted partial nephrectomy (RAPN) in patients with localized renal cell carcinoma (RCC) and to identify the predictors of Pentafecta achievement following RAPN. MATERIALS AND METHODS: We retrospectively analyzed the data from 362 patients with RCC who underwent RAPN from 2008 to 2016. The criteria for Pentafecta achievement was defined as the Trifecta [warm ischemia time (WIT) ≤ 25 minutes, negative surgical margin, and no significant perioperative complications]; with the addition of renal function preservation, including over 90% preservation of the estimated-glomerular filtration rate (e-GFR); and no stage upgrade of chronic kidney disease at 1 year after surgery...

Port placement for robot-assisted laparoscopic urologic surgery can be critical to effective completion of the minimally invasive procedure. An ideal port template would allow unhampered access to all critical structures during surgery, easy access for the bedside assistant, and minimization of arm collision with the fewest ports necessary to minimize cosmetic impact. We present a comprehensive plan for the placement of ports across different procedures for a variety of upper tract (radical/partial nephrectomy, retroperitoneal radical/partial nephrectomy, and pyeloplasty), lower tract (prostatectomy, and cystectomy), combined upper/lower tract (nephroureterectomy, retroperitoneal lymph node dissection), and female pelvic surgeries...
