PURPOSE: To show the benefit of three-dimensional (3D) reconstructions of preoperative imaging for surgical performance. METHODS: A laparoscopic training environment with 15 hidden lymph nodes was designed. Three of them were marked with radiographic contrast agent and were only distinguishable from unmarked nodes via CT imaging. Thirty-six surgeons were divided into two groups. To group 1 the unprocessed CT data were shown. Group 2 was additionally shown a 3D reconstruction of the anatomy...

Emre Huri, Mehmet Ezer, Eddie Chan
Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training...

OBJECTIVES: To compare modified laparoscopic simple enucleation (MLSE) and standard laparoscopic partial nephrectomy (SLPN) for treating localized renal cell carcinoma in our large institutional experience. METHODS: We evaluated 385 consecutive patients who underwent MLSE or SLPN for renal tumors in our institution from January 2013 to December 2015 in terms of perioperative pathological and oncologic outcome variables. During MLSE, the single-layer suture technique was performed for renal reconstruction...

To investigate the clinical characteristics, treatments and prognosis of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusions (Xp11.2 tRCC), the epidemiological features and treatment results of 34 cases of Xp11.2 tRCC, which were diagnosed by immunohistochemistry staining of TFE3 and fluorescence in situ hybridization at our center, were retrospectively reviewed. The 34 patients included 21 females and 13 males aged 3 to 64 years (median age: 27 years). Four patients were children or adolescents (<18 years of age), and 26 patients were young or middle-aged adults (18-45 years)...

INTRODUCTION: Laparoscopic living donor nephrectomy is the standard of care at high-volume renal transplant centres, with benefits over the open approach well-documented in the literature. Herein, we present a retrospective analysis of our single-institution donor nephrectomy series comparing the mini-open donor nephrectomy (mini-ODN) to the laparoscopic donor nephrectomy (LDN) with regards to operative, donor, and recipient outcomes. METHODS: From 2007-2011, there were 89 cases of mini-ODN, at which point our centre transitioned to LDN; 94 cases were performed from 2011-2014...

INTRODUCTION AND OBJECTIVES: To analyze postoperative complications and to assess for significant predictive factors during partial nephrectomy (PN) using a large multicenter dataset. METHODS: Patients who underwent PN for clinical T1 renal tumors at 19 urological Italian centers (Registry of Conservative Renal Surgery [RECORd] project) were evaluated between 2009 and 2012. Anthropometric data, comorbidities and perioperative outcomes were analyzed. Complications were divided as intra- and postoperative, medical and surgical, as appropriate...

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...

Background: The development of laparoscopic and robotic surgeries represents the modern era with the objective of improving patient outcomes; this surgical method is widespread in urology and general surgery. Retroperitoneal laparoscopic/robotic surgery is common in urologic surgery, but not in liver surgery. Tumors located in the posterosuperior aspect of the liver are difficult to access using a transperitoneal approach, and control of bleeding can also be difficult, especially in patients with cirrhosis...

Partial nephrectomy is now the preferred surgical option for small renal tumors because it allows nephron preservation without compromising oncologic clearance. Its outcomes depend on the surgeon's ability to continuously identify the edges of the tumor during resection, thus leaving an adequate margin around the tumor without excessive removal of normal parenchyma, as well as keeping a short ischemic time. Folate receptors are highly abundant in the normal kidney, and there is a difference in folate receptor expression between malignant and normal renal tissues...

BACKGROUND: Two main techniques are adopted to perform partial nephrectomy in children: laparoscopy and retroperitoneoscopy. The aim of this paper is to review the larger multicentric experience recently published by our group to review indications, techniques and results of both approaches. METHODS: Data of 102 patients underwent partial nephrectomy in a 5-year period using minimally invasive surgery (MIS) procedures were analyzed. Fifty-two children underwent laparoscopic partial nephrectomy (LPN), and 50 children underwent retroperitoneoscopic partial nephrectomy (RPN)...

OBJECTIVES: Currently, there is no standardized training protocol to teach surgeons how to deal with vascular injuries during laparoscopic procedures. The purpose of this study is to develop and evaluate the effectiveness of a standardized algorithm for managing vascular injury during laparoscopic nephrectomies. MATERIALS AND METHODS: The performance of 6 surgeons was assessed during 10 laparoscopic nephrectomies in a porcine model. During the first and tenth operations, an injury was made in the renal vein without warning the surgeon...

OBJECTIVE: Surgical planning for robotic partial nephrectomy (RALPN) depends on preoperative imaging and interpretation of spatial relationships between tumor and renal anatomy. We describe our experience using patient specific tissue-like kidney models created with advanced 3D printing technology for preoperative planning and surgical rehearsal prior to RALPN . PATIENTS AND METHODS: A feasibility study of 10 patients with solid renal masses who underwent RALPN after preoperative rehearsal using 3D print models...

Aim - retrospective comparative analysis of results of laparoscopic partial nephrectomy (LPN) depending on the type of access and the size of the tumor. The study included 170 patients undergoing LPN during the period from 2010 to 2015 years. Among the patients was 108 males (63.5%) and 62 women (36.5%) ranging in age from 17 to 80 years (average age 56,6±0.9 years). Depending on the type of access and the size of the tumor patients divided into 4 subgroups-154 patients who performed transperitoneal LRP, 16 patients undergoing retroperitoneal partial nephrectomy, 117 patients with tumor less than 4 cm and 53 patients with tumor more than 4 cm...

INTRODUCTION: Between the two techniques of laparoscopic nephrectomy, retroperitoneoscopy has certain distinct advantages over transperitoneal access but may be a more difficult technique to learn. We present our experience of training novices in retroperitoneoscopic nephrectomy with a good outcome, making it a standard of care for nephrectomy at our institute. METHODS: The aim of this study was to report the initial experience, learning curve, and outcome of retroperitoneoscopic nephrectomy by novices under a mentored approach...

BACKGROUND: The aim of this study was to evaluate the efficacy of preoperative intravenous oxycodone administration on postoperative sufentanil consumption in patients undergoing retroperitoneal laparoscopic nephrectomy. METHODS: Fifty patients scheduled for retroperitoneal laparoscopic nephrectomy were enrolled and randomly assigned to two groups - patients in Group O (n = 25) received intravenously 0.1 mg kg⁻¹ oxycodone; while the patients in Group C (n = 25) received 0...

INTRODUCTION: In pediatric urology, partial nephrectomy is used primarily to remove a non-functioning renal moiety in a duplicated system. There are few data on infants undergoing this procedure. As such, we present a robot-assisted laparoscopic lower pole partial nephrectomy in an infant. METHODS: Our patient was an 11-month-old (10.7 kg) male with a history of prenatal hydronephrosis, who was diagnosed postnatally with a duplicated right collecting system and severe hydroureteronephrosis of the right lower collecting system...
