Nephron-sparing surgery (partial nephrectomy) results are similar to those of radical nephrectomy for small (<4 cm) renal tumors. However, in patients with end-stage renal disease, radical nephrectomy emerges as a more efficient treatment for localized renal cell cancer. Laparoscopic radical nephrectomy (LRN) increasingly is being performed. The objective of the present study was to present a c...

PURPOSE We evaluated the effect of warm ischemia time on early postoperative renal function following laparoscopic partial nephrectomy. MATERIALS AND METHODS Of 453 patients who were surgically treated for renal tumors between May 2001 and September 2007, and who were identified in our database 128 underwent laparoscopic partial nephrectomy. Of these 128 patients 101 who were evaluable had co...

BACKGROUND The complexity of laparoscopic partial nephrectomy (LPN) has prompted many laparoscopic surgeons to adopt robotic partial nephrectomy (RPN) for the treatment of small renal masses. We assessed the learning curve for an experienced laparoscopic surgeon during the transition from LPN to RPN. METHODS We compared perioperative outcomes of the first 20 patients who underwent RPN to the...

Partial nephrectomy, using open surgery or laparoscopy, is a standard surgical approach to treat renal disorders. The objective of this study was to compare and evaluate the feasibility and safety of laparoscopic partial nephrectomy using figure eight ligation technique. Mixed-breed dogs were randomly dedicated for partial nephrectomy using laparoscopy (n=6) and open surgery (n=6). During 30 da...

Calyceal diverticula are cystic dilations within renal parenchyma prone to urinary stasis, stone formation, and recurrent infection. Using ICD-9 code 55.39 and CPT code 50549, we identified five women and two men (mean age 42 years) who underwent laparoscopic calyceal diverticulectomy at our center from August 2007 to July 2010. Patient videos that highlight basic and advanced laparoscopic tech...

PURPOSE To test the viability of a new device to obtain hemostasis during laparoscopic partial nephrectomy (LPN) without vascular clamping. MATERIALS AND METHODS We performed a comparative experimental study between a new radiofrequency (RF)-assisted device consisting of a handheld instrument that simultaneously conducts coagulation and cutting tasks without hilar clamping vs a standard techn...

Partial nephrectomy is considered the standard of care for the management of small renal masses, and laparoscopic techniques are becoming popular for multiple reasons, one of which is minimal invasiveness. On the other hand, kidneys are extremely vascular organs, and renal hemorrhage is a major cause of morbidity after laparoscopic partial nephrectomies. Control of bleeding and management of ca...

PURPOSE Minimally invasive management of small renal tumors has become more common. We compared the results of partial nephrectomy by video-assisted minilaparotomy surgery (VAMS), open, and laparoscopic techniques. MATERIALS AND METHODS We retrospectively compared clinicopathological, oncological, and functional outcomes in 271 patients who underwent partial nephrectomy for renal tumors at on...
