Indocyanine Green (ICG) is frequently used during urologic robotic procedures and is generally considered to be safe. However, there are reported cases of severe complications from ICG when used for non-urologic purposes. We present the first case to our knowledge of anaphylactic shock in response to intravenous ICG during a robotic partial nephrectomy.

OBJECTIVES: To examine the dynamic and potentially synergistic influence of warm ischemia time (WIT) and excisional volume loss (EVL) on predicted rates of post-partial acute kidney injury (AKI) across a range of tumor complexities. To investigate whether these modifiable variables sensitize the kidney to the other's damaging influence. METHODS: We retrospectively reviewed 1,245 patients between 2006 and 2016 with bilateral kidneys and enhancing renal masses in our single-institution robotic partial nephrectomy (PN) database...

INTRODUCTION AND OBJECTIVE: The R.E.N.A.L. nephrometry system (RNS) has been validated in multiple open, laparoscopic and robotic partial nephrectomy series. The aim of this study was to test the accuracy of R.E.N.A.L. nephrometry system in predicting perioperative outcomes in surgical treatment of kidney tumors <7.0cm in a prospective model. MATERIALS AND METHODS: Seventy-one patients were selected and included in this prospective study. We evaluate the accuracy of RNS in predicting perioperative outcomes (WIT, OT, EBL, LOS, conversion, complications and surgical margins) in partial nephrectomy using ROC curves, univariate and multivariate analyses...

Renal function after partial nephrectomy (PN) may depend on modifiable factors including ischemia time, excision of healthy parenchyma (excisional volume loss, EVL), and reconstructive methods. We retrospectively reviewed our institutional robotic PN database to identify the predictors of glomerular filtration rate (GFR) preservation (GFR-P) at 3-12 mo postoperatively, during which GFR decline plateaus. Baseline clinical, sociodemographic, and radiologic characteristics were captured. Univariate and multivariate (MV) linear regression analyses were performed and marginal effects were employed to examine the relative effect of EVL on renal function...

A duplex kidney system with an ectopic ureter draining into the vagina is a congenital malformation that typically presents as refractory urinary incontinence. Diagnosis is often difficult to establish and delayed due to a low incidence. We present the case of a patient aged 26 years with a life-long history of persistent urinary incontinence. Initial presentation was at childhood; however, the diagnosis went undetermined for 22 years. CT urography revealed a duplex kidney with an atrophic upper pole associated with an ectopic ureter that drained into the vaginal vault...

Robotic partial nephrectomy (RPN) is gaining increasing prominence for nephron sparing surgery in the treatment of patients with localized kidney tumors. RPN offers the benefits of minimally invasive surgery with a shorter learning curve compared to its laparoscopic counterpart. While long-term data are awaited, RPN does provide short-term oncological and functional outcomes comparable to open and laparoscopic PN. Further, robotic surgery has facilitated technical innovation including the elimination of warm ischemia, provided minimally invasive alternatives to patients with complex tumors and importantly, has fuelled increased dissemination of PN surgery amongst community urologists...

To construct patient-specific physical three-dimensional (3D) models of renal units with materials that approximates the properties of renal tissue to allow pre-operative and robotic training surgical simulation, 3D physical kidney models were created (3DSystems, Rock Hill, SC) using computerized tomography to segment structures of interest (parenchyma, vasculature, collection system, and tumor). Images were converted to a 3D surface mesh file for fabrication using a multi-jet 3D printer. A novel construction technique was employed to approximate normal renal tissue texture, printers selectively deposited photopolymer material forming the outer shell of the kidney, and subsequently, an agarose gel solution was injected into the inner cavity recreating the spongier renal parenchyma...

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...

OBJECTIVE: To identify the preoperative factors associated with conversion from robotic partial nephrectomy (RPN) to radical nephrectomy (RN), and to report the incidence of this event. PATIENTS AND METHODS: Using our institutional review board-approved database, we abstracted data on 1023 RPN cases performed at our center between 2010 and 2015. Standard and converted cases were compared in terms of patients and tumor characteristics and perioperative, functional, and oncological outcomes...

PURPOSE: When accidental tumor incision (ATI) has occurred during open partial nephrectomy (PN), scissors can be changed easily. In contrast, during laparoscopic partial nephrectomy (LPN) or robotic partial nephrectomy (RPN), it is time consuming and expensive especially during RPN to change scissors. This study investigates whether tumor cells remain on the surface of scissors after ATI during PN and investigates an alternative way to avoid changing scissors during LPN and RPN. MATERIALS AND METHODS: We subcutaneously injected 786-O renal-cell carcinoma (RCC) cells containing enhanced green fluorescent protein (786-O/EGFP) into six mice...

INTRODUCTION: American Urological Association 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 postoperative fluid collections. Our primary objective was to evaluate the frequency of indeterminate postoperative imaging results and how those radiographic findings altered patient management...

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...
