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...

PURPOSE To compare operating room times between retroperitoneal robot-assisted laparoscopic radical prostatectomy (RALRP) and pure retroperitoneal laparoscopic radical prostatectomy (LRP). PATIENTS AND METHODS From March 2007 to April 2008, 288 patients underwent an extraperitoneal LRP in our institution. Eighty-three LRPs were performed with robot assistance using the da Vinci Surgical Syste...

Spontaneous rapture with consequent retroperitoneal hemorrhage (Wunderlich's syndrome) is the complication mostly feared from large renal angiomyolipomas (RAMLs). In hemodynamic stable patients, minimal invasive therapies have superseded open surgery as the mainstay of treatment, with contemporary cases mostly treated by selective arterial embolization. Robotic-assisted laparoscopic partial nep...

PURPOSE Open partial nephrectomy has proven long-term oncological efficacy. Long-term outcomes of laparoscopic partial nephrectomy are pending. We present the long-term outcomes of patients undergoing laparoscopic or open partial nephrectomy for a single cT1 renal cortical tumor 7 cm or less. MATERIALS AND METHODS Of 2,246 patients undergoing partial nephrectomy for a single cT1 tumor (1999 t...

PURPOSE Laparoscopic radical nephrectomy (LRN) is more challenging with increases in body mass index (BMI). Several recent studies have shown, however, that LRN can be safely performed even in obese patients. The influence of obesity on the perioperative outcomes of LRN has not been well elucidated for large renal tumors (>7 cm), however. We estimated the impact of obesity on LRN for stage T1 a...

In urology, the main use for the robotic technique has been in radical prostatectomy for prostate cancer. Robotic surgery for other organs, such as the kidneys and bladder, has been less explored. However, partial nephrectomy or radical nephroureterectomy can be difficult for inexperienced laparoscopic surgeons. The advent of the da Vinci robot, with multijointed endowristed instruments and ste...

BACKGROUND Due to the recent development of laparoscopic devices, laparoscopic radical nephrectomy is the standard procedure for localized renal cell carcinoma. However, some studies have reported postoperative port site metastasis in several cancers. CASE PRESENTATION A 68-year-old Asian-Japanese man was referred to our hospital for a further examination of his right renal tumor in 2009. Due...
