Introduction. Several studies have shown the feasibility and safety of both transperitoneal and posterior retroperitoneal approaches for single incision laparoscopic adrenalectomy, but none have compared the outcomes according to the left- or right-sided location of the adrenal glands. Materials and Methods. From 2009 to 2013, 89 patients who received LAMP (laparoscopic adrenalectomy through mo...

PURPOSE To describe our technique and experience with retroperitoneoscopic upper pole nephroureterectomy in duplex kidney, focusing on the role of dilated upper ureter. MATERIALS AND METHODS From November 2004 to August 2011, retroperitoneoscopic upper pole nephroureterectomy was performed in 31 patients with a duplex kidney by a single, experienced laparoscopic surgeon. We developed our own ...

BACKGROUND To evaluate the safety and efficacy of the completely retroperitoneoscopic nephroureterectomy (CRNU), a retrospectively comparative study between completely and traditionally retroperitoneoscopic nephroureterectomy (TRNU) was done in a single center. METHODS From January 2014 to December 2014, 107 patients with upper tract urothelial cancer (UTUC) underwent CRNU. The kidney was ret...

BACKGROUND Changing from an open to a laparoscopic live renal donor programme poses challenges and may affect donor and graft outcomes. OBJECTIVES To evaluate donor safety and graft outcomes for the first 50 retroperitoneoscopic live donor nephrectomies performed at Tygerberg Hospital, Cape Town, South Africa. METHODS The procedures were performed by a single surgeon from 8 April 2008 to 3 ...

BACKGROUND Transplantation is the only treatment offering long-term benefit to patients with chronic kidney failure. Live donor nephrectomy is performed on healthy individuals who do not receive direct therapeutic benefit of the procedure themselves. In order to guarantee the donor's safety, it is important to optimise the surgical approach. Recently we demonstrated the benefit of laparoscopic ...

OBJECTIVE We evaluated the role of retroperitoneoscopic pyelolithotomy in the management of renal calculi. METHODS Fifty-six cases (male, 27; female, 29) of solitary or multiple renal calculi were evaluated in the study. There were 46 patients with a single calculus, 4 patients with a staghorn calculus, and 6 with a caliceal calculus. Retroperitoneoscopic pyelolithotomy was carried out after ...

OBJECTIVE To compare classical open pyeloplasty with retroperitoneal laparoscopic pyeloplasty in effectiveness, potential advantages and complications. MATERIALS AND METHODS Between March 2006 and April 2010, 113 patients with ureteropelvic junction obstruction underwent retroperitoneal laparoscopic dismembered pyeloplasty were retrospectively compared with those of 59 patients who underwent ...
