The advantages of retroperitoneoscopic technique are well known. We decided to combine this access with the emerging laparoendoscopic single-site surgery (LESS) technique. We present our preliminary data on 11 renoureteral procedures and describe our retroperitoneoscopic LESS technique. As of March 2009, 10 patients were submitted to retroperitoneal LESS and divided into three groups: Group A, ...

nelson's syndrome is usually characterized by hyperpigmentation, elevated level of acth, and pituitary adenoma, which is frequently available as macroadenoma. it is usually occurred in the patients suffering from cushing's syndrome. growth of tumor has been revealed in 10-30% of the patients following adrenalectomy. tumors are often benign in nelson's syndrome. the selected treat...

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 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 ...

PURPOSE Retroperitoneoscopic radical nephrectomy (RRN) has been performed at Yokohama City University Medical Center since May 2002. Three surgeons have become skilled in performing RRN without major complications. We investigated the outcomes of the surgery and attempt to clarify whether the technique we adopted is suitable to perform this procedure safely. PATIENTS AND METHODS Between May 2...

OBJECTIVES We retrospectively performed a comparative analysis of retroperitoneoscopic and open donor nephrectomy in terms of donor complications, as well as recipient complications and functional graft outcome. METHODS A total of 134 donor nephrectomies including 69 open (ODN) and 65 retroperitoneoscopic (RDN) nephrectomies was analyzed retrospectively. Both groups were comparable in terms o...
