OBJECTIVE: To analyze the efficacy of open nephron-sparing surgery (NSS) in the treatment of complex renal cell carcinoma. PATIENTS AND METHODS: A total of 118 patients with complex renal cell carcinoma (T1N0M0, clear cell carcinoma) were included in this study, and assigned into open radical nephrectomy (RN) group (35 patients), open NSS group (45 patients) and laparoscopic NSS group (38 patients). After 3 years of follow-up, the clinical efficacy was analyzed...

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...

PURPOSE: Saving warm ischaemia time (WIT) in laparoscopic partial nephrectomy (LPN) is very important. We have designed a new device, a remotely activated bulldog clamp, to facilitate LPN. In present study, the effectiveness, convenience and safety of the new design device were compared with that of standard bulldog vascular clamp in a pig model. MATERIALS AND METHODS: Fifteen cases of LPN were bilaterally operated on upper or lower pole of kidneys in five pigs...

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...

Laparoscopic donor nephrectomy (LDN) can be performed via either transperitoneal or retroperitoneal approach. Very few studies have been carried out till now, comparing immunologic and inflammatory responses in donors after these two approaches. This is a prospective observational study. Selection of approach was decided by the operating surgeon. All patients underwent peripheral venous blood sampling preoperatively and 24 h postoperatively for the measurement of C-reactive protein (CRP), interleukein-6 (IL-6), total leukocyte count (TLC), blood urea nitrogen (BUN), and serum creatinine (SCr)...

Testicular metastases from renal clear cell carcinoma (RCC) are extremely uncommon. To the best of our knowledge, only 32 cases have been reported in the literature. We report a rare case of testicular metastasis from RCC. A 69-year-old patient presented with discomfort and pain in his left testis. He had undergone laparoscopic left radical nephrectomy at another institution. Scrotal ultrasonography revealed a non-palpable lesion at the upper pole of the left testis with hypoechoic aspect, highly suspicious for malignancy...

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...

Transplant programs inform potential donors that they should be able to return to normal activities within ~2 weeks and to work by 6 weeks after laparoscopic nephrectomy. We studied actual time. Between 10/2004 - 9/2014, 911 donors having laparoscopic nephrectomy were surveyed 6 months post-donation. Surveys asked questions specific to their recovery experience, including time to return to normal activities and work; and a description of their recovery time relative to pre-donation expectations. Of the 911, 646 (71%) responded: mean age at donation was 43...

OBJECTIVE: To assess the feasibility of retroperitoneal laparoscopic nephrectomy combined with bench surgery and autotransplantation in treating complex renal tumor. PATIENTS AND METHODS: Six patients with complex renal tumor were seen in our institution between 2010 and 2014. Three patients with bilateral renal cell carcinoma underwent retroperitoneal laparoscopic nephrectomy on both sides. Extracorporeal tumorectomy and renal reconstruction were performed on the side of the smaller tumor and then kidney autotransplantation was performed...

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...

Surgery in patients with hemophilia is a serious challenge. It requires a comprehensive approach, as well as careful postoperative monitoring. We present here the first case of a transperitoneal laparoscopic radical nephrectomy (TLRN) for renal cell carcinoma, of the clear-cell type, performed in a hemophilia B patient. The level of factor IX clotting activity before surgery and on postoperative days 1-6 was maintained at 65-130% and at 30-40% on subsequent days until healing of the post-operative wound was achieved...

OBJECTIVES: To evaluate the possible role of an hemostatic matrix on hemostasis, perioperative outcomes and complications in patients who underwent laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS: Patients charts were analyzed retrospectively and their demographic characteristics, operative parameters and follow-up results were recorded. Patients were divided into two groups, according to those who used an hemostatic matrix as Group 1 (n = 41) and those who did not used as Group 2 (n = 44)...

INTRODUCTION: Robotic-assisted laparoscopic radical nephrectomy (RRN) is an increasing utilized alternative to laparoscopic radical nephrectomy (LRN); however, there is a little data on comparative effectiveness and cost of these procedures. We analyzed perioperative outcomes and hospital charge difference among patients undergoing laparoscopic radical nephrectomy (LRN) and robotic radical nephrectomy (RRN). MATERIALS AND METHODS: Our institutional renal mass registry was queried for patients who underwent either LRN or RRN from 2010 to 2014...

PURPOSE: To evaluate effect of intraperitoneal bupivacaine on postoperative pain in patients undergoing laparoscopic live donor nephrectomy. METHODS: Hundred patients undergoing laparoscopic live donor nephrectomy were included in the study and were divided randomly into two groups based on computer-generated randomization chart of fifty each. Patients were made familiar with VAS chart preoperatively. Group A received 20 mL of 0.5 % bupivacaine, while group B patients received 20 mL of 0...

OBJECTIVES: T1 ventral renal hilar tumors (VRHTs) represent a very special type of tumor, for which laparoscopic partial nephrectomy (LPN) by the retroperitoneal approach is challenging. In this study, we report our surgical technique and Trifecta results. METHODS: Renal rotation technique has been established for retroperitoneal laparoscopic partial nephrectomy (RLPN) for VRHTs in our institution. Trifecta was used as a composite outcome measure for assessing quality of PLPN using this technique...

BACKGROUND: Minimally invasive surgery (MIS) is rising in popularity generating a revolution in operative medicine during the past few decades. Although laparoscopic techniques have not significantly changed in the last 10 years, several advances have been made in visualization devices and instrumentation. METHODS: Our team, composed of surgeons and biomedical engineers, developed a magnetic levitation camera (MLC) with a magnetic internal mechanism dedicated to MIS...
