OBJECTIVES: To evaluate the outcomes of robotic partial nephrectomy compared with those of laparoscopic partial nephrectomy for T1 renal tumors in Japanese centers. METHODS: Patients with a T1 renal tumor who underwent robotic partial nephrectomy were eligible for inclusion in the present study. The primary end-point consisted of three components: a negative surgical margin, no conversion to open or laparoscopic surgery and a warm ischemia time ≤25 min. We compared data from these patients with the data from a retrospective study of laparoscopic partial nephrectomy carried out in Japan...

We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up...

Kidney cancer is the third most common urologic malignancy and a 2% annual increase in the incidence has occurred over the past two decades, largely because of the increased utilization of imaging. The majority of these tumors are small, so the indications for nephron-sparing surgery and for minimally invasive surgery are continually expanding. Complex kidney lesions, such as those completely endophytic, are still a challenge even for experienced surgeons. Our objective is to demonstrate the operative technique for laparoscopic partial nephrectomy with the aid of intra-operative ultrasound in a man with a totally endophytic renal lesion...

Robotic-assisted kidney transplantation (RKT) with the Da Vinci (Intuitive, USA) platform has been recently developed to improve outcomes by decreasing surgical site complications and morbidity, especially in obese patients. This potential paradigm shift in the surgical technique of kidney transplantation is performed in only a few centers. For wider adoption of this high stake complex operation, we aimed to develop a procedure-specific simulation platform in a porcine model for the training of robotic intracorporeal vascular anastomosis and evaluating vascular anastomoses patency...

REVIEW
Philipp Stiegler, Peter Schemmer
Minimally invasive surgery is standard procedure for many operations. Further refinements include the introduction of robotic surgery which is still an emerging field especially in laparoscopic surgery. Since the successful introduction of the da Vinci Robotic Surgical System, the robotic approach in organ transplantation has become of great interest in both the live donor organ retrieval and the recipient operation. Robotic surgery for kidney, liver, and pancreas transplantation is feasible. Over 700 donor nephrectomies and 100 kidney transplantations have been performed already, and robotic surgery is standard in a small number of pioneer centers; however, larger series and most importantly randomized controlled trials for the highest evidence are needed...

BACKGROUND: Hand-assisted laparoscopic nephrectomy (HALDN) is currently the procedure of choice for obtaining living donor kidneys for transplantation. In our institution, it has been the standard procedure for 5 years. Previous studies have shown the same function of the graft as that obtained by open surgery, with a lower rate of bleeding and no differences in complications. We sought to demonstrate the experience and safety of HALDN compared with open donor nephrectomy in healthy donors for kidney transplantation...
