PURPOSE To report the prevalence of new-onset renal insufficiency in patients undergoing laparoscopic partial nephrectomy (LPN) as compared to laparoscopic radical nephrectomy (LRN) for pathologic T1a lesions. PATIENTS AND METHODS Forty-eight patients and 37 patients with a normal contralateral kidney, preoperative creatinine (Cr) concentration <2 mg/dL, and tumors <4 cm in size underwent LPN...
Laparoscopic Nephrectomy Is Cost Effective Compared With Open Nephrectomy in a Large County Hospital
BACKGROUND AND OBJECTIVES To evaluate the experience with laparoscopic nephrectomy in a large county hospital and perform a cost comparison between uncomplicated open and laparoscopic nephrectomy. METHODS Eleven consecutive patients who underwent an uncomplicated laparoscopic nephrectomy in a large county hospital were compared with 8 patients who underwent uncomplicated open nephrectomy duri...
Kidney cancer is the third most common urologic malignancy and a 2% annual increase in the incidence has occurred over the past two decades, largely because of the increased utilization of imaging. The majority of these tumors are small, so the indications for nephron-sparing surgery and for minimally invasive surgery are continually expanding. Complex kidney lesions, such as those completely e...
Renal function can be significantly preserved after nephron-sparing surgery by decreasing the intraoperative ischemic duration or by performing off-clamp surgery. We report the case of a 56-year-old woman diagnosed with a minimal-fat angiomyolipoma arising from the renal capsule, which was successfully treated by retroperitoneoscopic partial nephrectomy without hilar clamping. Computed tomograp...
INTRODUCTION Renal involvement by hydatid disease is uncommon. The patients may be asymptomatic or present with flank pain, hematuria, and hypertension. Surgery is the mainstay of treatment, and options include cyst deroofing, partial nephrectomy, and total nephrectomy. We share our experience of laparoscopic management of 3 patients with large hydatid cysts of the kidney and review the literat...
Objectives: The aim of this study was to compare the results of laparoscopic donor nephrectomy with open donor nephrectomy. Methods: A non-randomized prospective analysis was conducted of living donor kidney transplantations (118 open donor nephrectomies; 57 laparoscopic donor nephrectomies) between January 2005 and December 2007 in the Kidney Transplantation Unit of Hospital das Clínicas of Fa...
OBJECTIVE Prolonged warm ischemia time and increased intra-abdominal pressure caused by pneumoperitoneum during a laparoscopic donor nephrectomy could enhance renal ischemia reperfusion injury. For this reason, laparoscopic donor nephrectomy may be associated with a slower graft function recovery. However, an adequate protective response may balance the ischemia reperfusion damage. This study i...
PURPOSE We performed a meta-analysis of the literature to define the current expectations of complications during laparoscopic renal surgery. MATERIALS AND METHODS References were searched in the MEDLINE database from 1995 to 2004 using the terms complications and laparoscopic nephrectomy. Inclusion criteria were any series with greater than 20 cases, patient age older than 16 years and any c...
PURPOSE Laparoscopic radical nephrectomy has been accepted as the preferred management for low stage renal masses not amenable to partial nephrectomy. Early in the mid 1990s several studies suggested that obesity should be a relative contraindication to laparoscopy. We present our surgical outcomes and complications in patients undergoing open and laparoscopic nephrectomy, stratified by body ma...
Objective To describe use of a robotic-assisted laparoscopic partial nephrectomy technique utilizing the thulium laser for tissue welding without clamping the hilar vessels. Materials and Methods A Thulium laser at 30W and a 400 micron fiber placed through a robot arm to excise and achieve hemostasis during resection of renal masses. The masses were localized intraoperatively with a 10mm laparo...
