In accordance with increase of incidental renal tumor, partial nephrectomy is currently recommended as the gold standard for small renal mass. Since the nephron sparing may prevent the sequelae of chronic kidney disease, elderly patients might be especially appropriate for laparoscopic partial nephrectomy. However, tissue ischemia may occur when the procedure accompany with a vascular clamp whi...

OBJECTIVE High-intensity focused ultrasound (HIFU) permits targeted homogeneous ablation of tissue. The objective of this phase 1 study was to evaluate the feasibility of HIFU ablation of small renal tumours under laparoscopic control. PATIENTS AND METHODS Ten kidneys with solitary renal tumours were treated with a newly developed 4.0 MHz laparoscopic HIFU probe. In the first two patients wit...

PURPOSE : To assess the clinic value of application of laparospic ultrasonography (LU) in partial nephrectomy of small renal cell carcinoma. MATERIALS AND METHODS From 2007 to 2011, 28 small renal cell carcinoma patients in ou clinic underwent laparoscopic partial nephrectomy with LU. For comparison with preoperative conventional ultrasound and CT, we collected ultrasonic performance of the a...

parenchymal malignancy, and although complete or partial nephrectomy remains the gold standard of management, many minimally invasive treatment techniques, including laparoscopic or open partial nephrectomy, cryotherapy, and radiofrequency ablation (RFA) are emerging. RFA involves the conversion of an alternating current into heat, which destroys soft tissues by desiccation and coagulative necr...

Computer-assisted robotic renal surgery (CARRS) is a minimally invasive surgical treatment option for renal tumors. We review the literature regarding techniques and outcomes and the potential advantages of CARRS. We retrospectively reviewed the literature regarding techniques and outcomes of CARRS, with specific analysis on robotic radical nephrectomy (RRN) and robotic partial nephrectomy (RPN...

PURPOSE Laparoscopic radical nephrectomy has emerged as a standard of care in appropriate candidates with clinical stage T1 renal tumors (7 cm or less). Herein we present our experience with laparoscopic radical nephrectomy for clinical stage T2 tumors (greater than 7 cm). MATERIALS AND METHODS Patients undergoing laparoscopic radical nephrectomy between September 1997 and July 2003 were retr...

OBJECTIVE To evaluate our complications in renal and adrenal transperitoneal laparoscopic surgeries with Clavien-Dindo classification. MATERIAL AND METHODS Two hundred and eight patients to whom renal and adrenal laparoscopic surgeries were performed between January 2008 and June 2015 were included the study. One hundred and twenty one (58.2%) patients were female and 87 (41.8%) of them were ...

INTRODUCTION AND OBJECTIVE The R.E.N.A.L. nephrometry system (RNS) has been validated in multiple open, laparoscopic and robotic partial nephrectomy series. The aim of this study was to test the accuracy of R.E.N.A.L. nephrometry system in predicting perioperative outcomes in surgical treatment of kidney tumors <7.0cm in a prospective model. MATERIALS AND METHODS Seventy-one patients were sel...

INTRODUCTION To describe the technical considerations of laparoscopic nephron-sparing surgery in 3 complicated cases involving kidneys with renal arterial disease. TECHNICAL CONSIDERATIONS Three candidates for nephron-sparing surgery each had a renal mass, measuring 5.0, 3.5, and 2.5 cm, respectively. The renal arterial pathologic features in the tumor-bearing kidney included renal artery ste...

PURPOSE During laparoscopy, as in open surgery, exposure is critical. Here, we describe the use of a laparoscope holder to facilitate the liver lift during urological laparoscopic surgery. MATERIALS AND METHODS Laparoscopic right radical nephrectomy (n = 3), partial nephrectomy (n = 1), and adrenalectomy (n = 2) were performed with 4 ports. At the beginning of the operation, the small snake r...
