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 determine whether patient-specific 3D printed renal tumor models change pre-operative planning decisions made by urological surgeons in preparation for complex renal mass surgical procedures. MATERIALS AND METHODS: From our ongoing IRB approved study on renal neoplasms, ten renal mass cases were retrospectively selected based on Nephrometry Score greater than 5 (range 6-10). A 3D post-contrast fat-suppressed gradient-echo T1-weighted sequence was used to generate 3D printed models...

Objective: To study the safety and feasibility of using monopolar coagulation in sutureless laparoscopic partial nephrectomy (LPN). Methods: From February 2015 to March 2016, sutureless LPN using monopolar coagulation was performed on 25 patients with renal tumors. Mean patient age was 50 years (range 31 to 68). Mean tumor size was 4.1 cm (range 1.2 to 10.1). Mean RENAL nephrometry score was 6.1 (range 4 to 12). The renal hilar vessels were clamped in 14 surgeries, whereas 11 surgeries were carried out without clamping...

OBJECTIVES: To evaluate a multicenter series of robotic assisted partial nephrectomy (RAPN) performed for the treatment of large angiomyolipomas (AMLs). MATERIALS AND METHODS: Between 2005-2016, 40 patients with large or symptomatic AMLs underwent RAPN at 5 academic centers in the United States. Patient demographics, AML characteristics, operative and postoperative clinical outcomes were recorded and analyzed. Surgical outcomes were compared between patients who underwent selective arterial embolization (SAE) before RAPN and patients who did not undergo pre-RAPN SAE...

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...

PURPOSE: Partial nephrectomy is the gold standard treatment for small kidney masses. Data on the comparison oflaparoscopic (LPN) versus open partial nephrectomy (OPN) are based on retrospective studies. Thus, we plannedto compare these two techniques in a prospective trial. MATERIALS AND METHODS: The study population consisted of patients over 18 years old with single renal mass of≤ 4 cm. Patients were divided into two groups considering their preference. Study arms were matched accordingto age, gender, tumor size and location and renal nephrometry score...

OBJECTIVE: In this study we aimed to compare renal functions in patients who underwent robotic partial nephrectomy (RPN) with on-clamp and zero- ischemia techniques. MATERIAL AND METHODS: Between 2009 and 2015, 12 off-clamp and 22 on-clamp RPN procedures were performed on a total of 34 patients in two centers. The main outcome parameters examined were serum creatinine, and estimated glomerular filtration rate (eGFR) during preoperative, immediate postoperative periods, and at postoperative 3(rd) months...

Background: To report the first case of a renal schwannoma excised with robot-assisted laparoscopy. Case Presentation: A 43-year-old Caucasian female patient with vague abdominal symptoms was noted to have incidental right renal mass. Physical examination and laboratory tests were within normal limits. CT revealed a 4.6 cm heterogeneous enhancing right renal mass arising near the hilum. RENAL nephrometry score was 11a. She was treated by right robot-assisted laparoscopic nephrectomy. She recovered well without complications...

PURPOSE: A skilled assistant surgeon is presumed necessary during robot-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 perioperative outcomes in RAPN. MATERIALS AND METHODS: All RAPN cases in our healthcare system from January 2011 to December 2013 were retrospectively reviewed...

OBJECTIVES: Symptomatic angiomyolipoma (AML) and asymptomatic AML larger than 4 cm in size are usually treated with nephron-sparing surgery or transarterial embolization. We used radiofrequency ablation to treat the vascular pedicle of exophytic AML with low R.E.N.A.L. nephrometry score and investigated its feasibility for hilar off-clamping nephron-sparing surgery. METHODS: Contrast-enhanced computed tomography (CT) showed enhanced, well-defined lipomatous tumors with a maximum diameter of 4-8 cm in the kidney of 15 patients...

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...
