INTRODUCTION We sought to compare surgical outcomes between transperitoneal and retroperitoneal robotic partial nephrectomy (RPN) for posterior tumors. PATIENTS AND METHODS Using our multi-institutional RPN database, we reviewed 610 consecutive cases for posterior renal masses treated between 2007 and 2015. Primary outcomes were complications, operative time, length of stay (LOS), surgical ma...

OBJECTIVE • To establish its current status, this study reviews the literature, and reports developments in robotic-assisted partial nephrectomy (RPN), highlighting results from various studies that investigate the oncological and functional efficacy of RPN. Partial nephrectomy has become the standard therapy for the management of small renal masses. In an effort to overcome the perioperative m...

Acute renal papillary necrosis (RPN) in animals is characterized by increased renal lipid accumulation. The excretion of renal lipids into urine has been determined to evaluate their possible use as sensitive early biomarkers for the diagnosis of RPN. This study investigates injury induced by two model nephrotoxins, mefenamic acid (MFA), a non-steroidal anti-inflammatory drug (NSAID), and its a...

BACKGROUND Recent studies showed that robotic partial nephrectomy (RPN) offered outcomes at least comparable to those of laparoscopic partial nephrectomy (LPN). LPN can be particularly challenging for more complex tumors. OBJECTIVE To compare the perioperative outcomes of patients undergoing LPN or RPN for a single renal mass of moderate or high complexity. DESIGN, SETTING, AND PARTICIPANTS...

We have evaluated the potential of urinary uronic acid measurement as an early indicator in the development of renal papillary necrosis (RPN). Urinary uronic acid was quantified with a range of other urinary biochemical parameters in rats given multiple doses of N-phenylanthranilic acid (NPAA) or mefenamic acid (MFA), each of which induces a dose-related papillary necrosis. In addition, histolo...

PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as an alternative treatment for the management of small renal masses. This study was designed to investigate parameters that predict perioperative outcomes during RPN. MATERIALS AND METHODS We retrospectively reviewed the medical records of 113 patients who underwent RPN between September 2008 and May 2012 at the Seoul National Univ...

INTRODUCTION/OBJECTIVE Robotic-assisted partial nephrectomy (RPN) offers a mean length of stay (LOS) of 2 to 3 days. The purpose of this study is to determine the impact of modifiable and nonmodifiable risk factors on hospital LOS after RPN. PATIENTS AND METHODS We retrospectively reviewed our prospectively maintained database to identify all patients undergoing RPN for localized tumors at fi...

Industrial radiography has its inimitable role in non-destructive examinations. Industrial radiography devices, consisting of significantly high activity of the radioisotopes, are operated manually by remotely held control unit. Malfunctioning of these devices may cause potential exposure to the operator and nearby public, and thus should be practiced under a systematic risk control. To ensure ...
