PURPOSE: Urinary biomarkers of renal injury urinary may identify loss of renal function following nephron-sparing surgery (NSS). This study was designed to evaluate whether urinary l-type fatty acid-binding protein (l-FABP) is an early biomarker of loss of renal function after NSS. Specifically, the kinetics of urinary l-FABP level after NSS and its correlation with factors related to ischemic renal injury were analyzed. METHODS: This study prospectively evaluated 18 patients who underwent NSS between July and December 2014, including 12 who underwent laparoscopic and six who underwent robot-assisted partial nephrectomy...

Delayed sequelae following conservative management of renal trauma in the pediatric population are uncommon. Reports of delayed operations to manage these sequelae are even less common. Here we present the case of a 16-year-old male patient who had delayed development of upper urinary tract obstruction with recurrent infections following high-grade renal trauma managed conservatively. Ultimately he required a robotic-assisted partial nephrectomy two years after initial non-operative management. This is unique as no prior studies to our knowledge have described delayed hydronephrosis and delayed partial nephrectomy over a year following renal trauma...

Nephron-sparing surgery for the removal of small renal masses delivers equivalent oncological outcomes and better functional outcomes compared with those associated with radical nephrectomy. All contemporary partial nephrectomy techniques including open, laparoscopic and robotic approaches involve the use of hilar clamping in order to facilitate haemostasis, and to enable accurate tumour excision and parenchymal reconstruction. Zero ischaemia was subsequently introduced as a technique to eliminate the renal ischaemia induced by hilar clamping...

PURPOSE: Currently no data exists to guide renal surgeons on the perioperative use of renin-angiotensin (RAS) blockers despite their potential cardiorenal benefits. This study aims to assess the impact of resuming RAS blockers on postoperative renal function and adverse cardiac events following partial nephrectomy. PATIENTS AND METHODS: This is an observational analysis of patients undergoing robotic-assisted laparoscopic partial nephrectomy from 2006-2014 at a single institution...

INTRODUCTION: Solitary fibrous tumor (SFT) of the kidney represents a rare neoplasm, and its malignant potential seems to be scarce. Classically, a radical nephrectomy is regarded as the treatment of choice for this condition. CASE REPORT: We present the case of a 37-year-old male patient who underwent left robotic clampless partial nephrectomy of an SFT of the kidney. Our patient has been followed-up carefully, and at 15-month examination, he is free of recurrence...

OBJECTIVE: The aim of the study was to present a case series of the sparsely reported complication of chylous ascites (CA) after left sided robot-assisted laparoscopic partial nephrectomy (RALPN), identify possible risk factors for the development of postoperative CA, and explore current recommendations for identification, management and prevention of CA. MATERIAL AND METHODS: A retrospective review of patients that were treated with a RALPN during a one year time period (August 2012 to August 2013) by one surgeon at our institution was conducted...

OBJECTIVES: To assess the impact of approach on surgical outcomes in otherwise healthy obese patients undergoing partial nephrectomy for small renal masses. PATIENTS AND METHODS: Using our institutional partial nephrectomy database, we abstracted data on otherwise healthy (Charlson score ≤1 and bilateral kidneys), obese patients (body mass index >30 kg/m(2) ) with small renal masses (<4 cm) treated between 2011 and 2015. The primary outcomes were intraoperative transfusion, operative time, length of stay, and postoperative complications...

PURPOSE: To identify predictors of poor discharge quality after robotic partial nephrectomy (RPN) at a large academic center. METHODS: We queried our institutional RPN database for consecutive patients treated between 2011 and 2015. The primary outcome was poor discharge quality, defined as length of stay >3 days and/or unplanned readmission. The association between patient, disease, and provider factors and overall discharge quality was assessed using univariate and multivariable analyses...

OBJECTIVE: To evaluate the impact of therapeutic anticoagulant or antiplatelet on the morbidity of robot assisted partial nephrectomy (RAPN). MATERIAL AND METHODS: From 2011 to 2015, we retrospectively analysed a prospectively maintained institutional review board-approved database of RAPN from two academic departments of urology. We evaluated the occurrence of overall complications and hemorrhagic complications (pseudoaneurysm, arterio- venous fistula, hematoma, transfusion)...

PURPOSE: To compare perioperative outcomes between robotic partial nephrectomy and open partial nephrectomy for localized >7 cm tumors. METHODS: We identified patients in our institutional review boards approved database who underwent robotic partial nephrectomy or open partial nephrectomy for treatment of renal tumors >7 cm in size between January 2009 and August 2015. The operative-postoperative outcomes and complications were compared between groups. RESULTS: The number of patients with >7 cm renal tumors treated at our center with robotic partial nephrectomy and open partial nephrectomy were 54 and 56, respectively...

INTRODUCTION: Multifocal and hereditary kidney cancers often require repeated ipsilateral nephron sparing procedures with higher blood loss and complication rates when compared to first time renal surgery. Consequently, many surgeons avoid minimally invasive techniques in the setting. We present the characteristics, complications and short-term renal functional outcomes of patients who underwent a repeat robotic partial nephrectomy (rRPNx). MATERIALS AND METHODS: A database was retrospectively reviewed to identify patients who underwent robotic partial nephrectomies between January 2007 and December 2013...

Intravascular papillary endothelial hyperplasia (IPEH, Masson's Tumor) of the kidney is an unusual, benign vascular lesion. A rare case of recurrent IPEH in the kidney was presented in this article. A 50-year-old male with a diagnosis of a suspicious mass in the left kidney was referred to our center for robotic partial nephrectomy. Robotic zero ischemia partial nephrectomy was performed due to the suspicion of a renal malignancy. On the basis of the histopathological results, the patient was diagnosed as IPEH...

Nephron sparing surgery (NSS) is the gold standard treatment option for patients with a solitary kidney in order to preserve renal function. Open partial nephrectomy (OPN) has been long considered the standard care for NSS. Robotic partial nephrectomy (RPN) is being gradually used more commonly even for solitary kidney and complex tumors. There was no difference between RPN and OPN regarding the rate of intraoperative-postoperative complications and positive surgical margin (PSM) (RPN: 7.5%, OPN: 8%) for patients with solitary kidney who underwent partial nephrectomy for small renal masses...

OBJECTIVES: To analyze long-term outcomes of robot-assisted partial nephrectomy for treatment of complex cystic renal tumors. METHODS: We retrospectively analyzed the data of patients who underwent robot-assisted partial nephrectomy for cystic (n = 32) and solid (n = 263) renal masses at Severance Hospital, Seoul, Korea. The primary outcome was assessment of perioperative safety for cystic tumor. Secondary outcomes were evaluation of long-term oncological and functional results...

OBJECTIVE: To compare the surgical precision for optimizing nephron-mass preservation of tumor enucleation (TE) vs standard partial nephrectomy (SPN), with primary focus on functional outcomes. TE is presumed to optimize preservation of parenchymal mass and function but this has not yet been rigorously studied and quantified. MATERIALS AND METHODS: Robotic partial nephrectomy patients who had appropriate pre- and postoperative studies for analysis of parenchymal mass preservation specific to the operated kidney were included...
