PURPOSE: Partial nephrectomy (PN) represents the treatment of choice for localized renal tumor<7cm. Minimally invasive approaches are considered standard of care in many institutions. Maintaining acceptable warm ischemic time (WIT) while teaching robotic PN (RPN) remains challenging. The goal of the present study was to assess the effect of teaching RPN on WIT and renal function in patients undergoing RPN. METHODS: Patients undergoing RPN for cT1-T2 renal tumors were included...

PURPOSE: When accidental tumor incision (ATI) is occurred during open partial nephrectomy (PN), scissors can be changed easily. On the other hand, during Laparoscopic PN (LPN) or Robotic PN (RPN), it is time consuming and very expensive especially for RPN to change scissors. This study is to investigate whether tumor cells remain on the surface of scissors after ATI during PN, and is to investigate alternative way to avoid changing scissors during LPN and RPN. METHODS: We subcutaneously injected 786-O renal cell carcinoma (RCC) cells containing enhanced green fluorescent protein (786-O/EGFP) into 6 mice...

INTRODUCTION: AUA Guidelines for surveillance of renal cell carcinoma after partial nephrectomy recommend imaging within 3-12 months of surgery. Imaging following partial nephrectomy may be difficult to interpret due to the surgical defect, the use of surgical material, and normal post-operative fluid collections. Our primary objective was to evaluate the frequency of indeterminate post-operative imaging results and how those radiographic findings altered patient management. METHODS: Retrospective chart review from 2006 to 2013 of patients who had undergone open, laparoscopic, and robotic partial nephrectomy at our institution was completed...

The objective of this is to compare the surgical outcomes of partial nephrectomy (PN), performed via three different approaches: robot-assisted (RAPN), laparoscopic (LPN), and open (OPN), in a single non-academic regional center. The data of patients undergoing PN at our Department from 2005 to 2016 were prospectively collected. A logistic regression model adjusted for preoperative variables (age, tumor size, creatinine and hemoglobin, ASA and Padua scores) was performed to evaluate whether transfusion, conversion, and postoperative complication rate were influenced by the surgical approach...

REVIEW
Nobuyuki Hinata, Masato Fujisawa
The safety and efficacy of robot-assisted partial nephrectomy (RAPN) has been reported in Western countries. However, there are no similar reported studies of RAPN in Japan. Although common medical services are covered by public health insurance in Japan, RAPN had not been approved as a listed treatment for public insurance. We conducted a prospective clinical trial to confirm the efficacy and safety of RAPN in Japan. The aim of the present review article is to describe current status of RAPN in Japan and to introduce a part of clinical results obtained from the clinical trial...

INTRODUCTION Hilar clamping is often performed to facilitate robotic partial nephrectomy (RPN). Minimal clamping techniques may reduce renal ischemia, including early unclamping, selective clamping, and off-clamp RPN. We assess the utilization of clamping techniques in a large international consortium of surgeons performing RPN for complex tumors. METHODS We retrospectively evaluated 721 patients with complex tumors who underwent RPN at 11 centers worldwide between 2008 and 2014. Complex tumors were defined as renal masses with a nephrometry score > 6...
