INTRODUCTION: Robot-assisted partial nephrectomy (RAPN) with different arterial clamping techniques has increasingly been performed to avoid ischemic injury to nephron. However, postoperative renal function remains controversial. We determine the impact of each renal arterial clamping on surgical and renal outcomes after RAPN. MATERIALS AND METHODS: Patients who underwent RAPN at Siriraj Hospital from 2010 to 2016 were retrospectively reviewed and stratified into 3 cohorts: main-clamp (MAC), selective-clamp, and off-clamp...

The lack of globally established standards for learning urological laparoscopy has not prevented laparoscopic techniques from evolution and continuous development. Laparoscopy coexists with robotic surgery today, and in the last decade there have been many techniques that have undergone a boom with the use of a laparoscopic approach (total and partial nephrectomy, pyeloplasty, colposacropexy, etc.).We intend to evaluate the progressive incorporation of different surgical techniques in the laparoscopic learning program and, on the other hand, to analyze the evolution of training programs in urological laparoscopy to bring this type of techniques within the hospital surgical activity...

In laparoscopic surgery, the surgeon must operate with a limited field of view and reduced depth perception. This makes spatial understanding of critical structures difficult, such as an endophytic tumour in a partial nephrectomy. Such tumours yield a high complication rate of 47%, and excising them increases the risk of cutting into the kidney's collecting system. To overcome these challenges, an augmented reality guidance system is proposed. Using intra-operative ultrasound, a single navigation aid, and surgical instrument tracking, four augmentations of guidance information are provided during tumour excision...

Introduction In patients with localised renal cell carcinoma, the only curative treatment option is surgical tumour excision. Current national and European guidelines recommend partial nephrectomy in the form of an open or minimally-invasive procedure in case of small tumours. The aim of this study was to examine the use of radical (RN) or partial (PN) nephrectomy performed as open or minimally-invasive procedures in patients with pT1 /pT2 renal cell carcinoma at a tertiary referral centre. Patients and Methods This retrospective study included a total of 758 patients with localised renal cell carcinoma (pT1/pT2), who underwent PN or RN between 01/2008 and 10/2014...
