INTRODUCTION: Robot-assisted surgery is practiced more and more frequently in urology. Besides its place in prostatectomy for cancer, it also concerns partial nephrectomy (NP), in the treatment of renal tumors. The objective of this review is to compare the robot-assisted approach with laparoscopic or open approaches in partial nephrectomy in terms of functional or oncological outcomes and per- and postoperative complications. MATERIAL AND METHODS: A systematic review of the literature published from 2009 was carried out on PubMed...

INTRODUCTION: Renal duplication is a relatively common congenital abnormality of the urinary tract, but symptomatic duplex kidney is a rare presentation in adults. Traditionally, the treatment of choice for poorly functioning moiety has been heminephrectomy. There is extensive literature detailing the outcomes of minimally invasive upper pole heminephrectomy, but comparatively little published regarding lower pole resection, especially in adult patients. We present a series of 13 patients who underwent minimally invasive heminephrectomy for duplex kidney...

Renal cell carcinoma with inferior cava thrombus indicates biologically aggressive cancer, so the complete surgical resection remains standard of care with best long-term outcomes. Laparoscopic radical nephrectomy with vena cava thrombectomy represents nowadays a mini-invasive surgical alternative to the classic open nephrectomy. We present the case of a patient with incidental diagnosis of a right renal mass with level II inferior cava thrombus completely managed with both retroperitoneal and transperitoneal approaches...

INTRODUCTION: Advances in diagnostic techniques and treatment have resulted in an increase in patients with synchronous cancer. Surgical reports of combined laparoscopic and robotic resection for synchronous colorectal and genitourinary cancer are rare. MATERIALS AND METHODS: Between August 2015 and November 2017, three patients underwent combined laparoscopic and robotic surgery for synchronous colorectal and genitourinary cancer in our hospital. RESULTS: Case 1 was a 59-year-old man with synchronous rectal and prostate cancer treated by combined laparoscopic anterior resection and robotic-assisted prostatectomy...

OBJECTIVES: To describe the natural history of kidney function following partial nephrectomy (PN) for patients with renal cell carcinoma (RCC), and to identify independent predictors of whether patients with RCC will retain renal function unchangeable or even increased and develop functional impairment of ≧25% post-PN. PATIENTS AND METHODS: We performed a retrospective analysis of 337 cases involving patients diagnosed with RCC of pT1-2N0M0 who underwent laparoscopic PN, the primary endpoints included the stabilization or increase in postoperative estimated glomerular filtration rate (eGFR) compared to the preoperative level and eGFR impairment of ≧25% following surgery...

OBJECTIVE: To accurately predict the ischemic time (IT) and select candidates for transabdominal laparoscopic partial nephrectomy (LPN). METHODS: Transabdominal LPN was performed for 135 Japanese patients with renal masses <7cm in diameter between 2009 and 2016 by a single surgeon in a single institute. The renal parenchymal sutures were done with a combination of felt, Hem-o-lok and Lapra-Ty. The original R.E.N.A.L. nephreometry score (NS) was modified as follows...

BACKGROUND: Precise tumor excision and renal reconstruction significantly affect the amount of vascularized parenchyma preserved during minimally-invasive partial nephrectomy (MIPN), which is a primary determinant of ultimate renal function. However, current knowledge on renorrhaphy techniques is sparse with no consensus on the best approach. OBJECTIVE: to summarize the available evidence on renorrhaphy techniques and to assess their impact on perioperative outcomes after MIPN...

The clivus is an atypical metastatic site for renal clear cell carcinoma (RCCC). Here we report a 54 year old man with acute cavernous sinus syndrome. Brain magnetic resonance imaging identified a clival-based lesion with associated bony erosion. The patient underwent endoscopic endonasal biopsy and partial resection of the clival mass. Because histologic examination of the resected specimen resulted in a diagnosis of RCCC, contrast-enhanced computed tomography scan of the abdomen was performed and showed an enhanced left renal mass...

Between 15 and 20 % of patients diagnosed with renal cell carcinoma suffer from metastatic disease by the time of diagnosis. In addition to systemic therapy, there are various surgical strategies to treat the primary tumour, e. g. cytoreductive nephrectomy (CN) or palliative nephrectomy (PN). In the immunotherapy era, the standard treatment was to perform CN followed by interferon therapy, based on 2 prospective randomised trials and their combined analysis. Since the introduction of targeted therapy around 2005, data of that quality has been missing and clinicians have had to rely on big retrospective studies, which have confirmed the benefit of CN except for patients with low performance status, cerebral metastases, low life expectancy, and old age...

We report a case of living related renal transplantation that used the recipient's saphenous vein as a graft to extend the length of the right donor renal vein. A 41-year-old woman underwent ABO-incompatible living related renal transplantation from her 74-year-old mother in November 2014. A retroperitoneal laparoscopic right donor nephrectomy was performed, because the right kidney showed a cyst on preoperative computed tomography. As the right kidney after donor nephrectomy had a short renal vein and the kidney was large at 280 g, anastomosis with the external iliac vein was difficult...

INTRODUCTION: Studies evaluating robotic-assisted laparoscopic partial nephrectomy (RALPN) are limited to case series, amounting to a lack of studies directly comparing perioperative outcomes for RALPN to open partial nephrectomy (OPN). OBJECTIVE: To compare perioperative outcomes between RALPN and OPN. METHODS: A single-institution, retrospective cohort study was performed to compare perioperative outcomes (operative time (OT), length of stay (LOS), complications, readmissions, postoperative interventions, loss in size of the residual moiety, and the presence of postoperative 'contained fluid collections') for RALPN and OPN between February 2007 and July 2014...

OBJECTIVE: To describe a novel and simple technique of preliminary kidney parenchymal ligation using Endoloop® ligatures during laparoscopic partial nephrectomy (PN) without hilar clamping for polar complex tumor cases. METHODS: The subjects were 17 patients who had a renal mass with a R.E.N.A.L. nephrometry score ≥7 (7/8/9/10 in 3/6/6/2 patients, respectively) located in the pole of the kidney. Patient-specific 3D reconstructed kidney images were created for preoperative planning in all cases...

Mannitol is routinely used during partial nephrectomies due to its renoprotective properties. With minimally invasive techniques, the need for mannitol has been questioned. Robotic-assisted laparoscopic partial nephrectomy (RALPN) has been shown to decrease warm ischemia time, which may potentially minimize the benefit of mannitol. To date, no prospective, randomized, controlled trials have investigated the use of mannitol in only robotic procedures. We hypothesize that the intraoperative mannitol use during RALPN provides no statistically significant benefit for post-operative renal function outcomes...

INTRODUCTION: Since the first description of robot-assisted laparoscopic donor nephrectomy for living donor renal transplantation, additional studies have noted outcomes comparable to traditional laparoscopic surgery. Urologists have embraced the technical advantages of the robotic approach, including improved dissection and more accurate graft preservation. With the advent of robotic stapling, we aim to demonstrate the feasibility of the use of robotic stapling for living-donor nephrectomies...
