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...

INTRODUCTION: Indocyanine green (ICG) is a fluorescent molecule that provokes detectable photon emission. The use of ICG with near-infrared (NIR) imaging system (Akorn, Lake Forest, IL) has been described during robotic partial nephrectomy (RAPN) as an adjunctive means of identifying renal artery and parenchymal perfusion.We propose the use of the ICG with NIR fluorescence during laparoscopic robot-assisted radical prostatectomy (RARP), to identify the benchmark artery improving the preservation of neurovascular bundle and to improve the visualization of the vascularization and then the hemostasis...

Objective To compare the surgical outcomes between resection and enucleation in robot-assisted laparoscopic partial nephrectomy (RAPN) based on the Surface-Intermediate-Base margin score (SIB score). Patients and Methods This study included 282 patients who underwent RAPN between 2014 and 2016. SIB score was macroscopically evaluated immediately after the surgery. We divided the patients into the following two groups: enucleation (SIB score, 1-2) and resection (SIB score, 3-5). To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching...

Partial nephrectomy is the gold standard for the renal tumours less than 7 to 10cm whenever feasible in order to preserve renal function. The extension of nephron-sparing surgery using a mini-invasive approach is possible by robotic surgery. Radical nephrectomy is mandatory in the other situations and especially in case of locally advanced renal carcinoma. The place of cytoreductive nephrectomy in metastatic renal cell carcinoma is the purpose of the CARMENA trial. Tyrosine kinase inhibitors are currently the first line treatment; but in the near future new immunotherapy by checkpoints molecules could crucially change the treatment of metastatic renal cell carcinoma...

Renal artery vasospasm can be a troublesome complication during robot-assisted laparoscopic partial nephrectomy. Urologists performing this procedure, especially if utilizing selective arterial vascular microdissection, should be aware of using papaverine for both prevention and treatment of renal artery vasospasm. We present a 33-year-old male who developed severe renal artery vasospasm just with hilar dissection causing the kidney to become ischemic. Papaverine was topically applied on the renal arteries resulting in vasodilation and reperfusion of the kidney...
