BACKGROUND: Laparoscopic donor nephrectomy has become the standard of care due to multiple benefits. Currently, there are various techniques employed with two different approaches: transperitoneal (TLDN) or retroperitoneoscopic (RLDN) approach. There is a lack of data to determine which technique is superior, although the RLDN offers an anatomical advantage by avoidance of manipulation of the intraperitoneal organs. The aims of this study were to explore the merits of RLDN to TLDN and assess the learning curve of transition from TLDN to RLDN...

BACKGROUND: Cryoablation has emerged as an alternative to the more invasive partial nephrectomy for small renal masses. The approach can be carried out by two techniques, either laparoscopic (LCA) or percutaneous with CT guidance (PCA). We aimed to compare between the two procedures. MATERIAL & METHODS: A systematic review and meta-analysis was conducted including studies comparing the two techniques. Outcomes included incomplete ablation, late local recurrence, cancer specific survival, procedure time, transfusion rates, hospital stay, and complications...

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...

Partial (2/3) nephrectomy can be performed via the laparoscopic, retroperitoneal, and transperitoneal approach. Outcomes of the three approaches were compared in this study. 2/3 nephrectomy were performed in 21 healthy Bama miniature pigs (mean bodyweight 20.59±2.78kg). Pigs were divided into three groups: those that underwent 2/3 nephrectomy via laparoscopy (LN group, n=7), the retroperitoneal approach (RN group, n=7), or the transperitoneal approach (TN group, n=7). We monitored pre- and postoperative physiologic parameters, blood cell count, and stress and renal function biomarkers...
