PURPOSE We report our experience to date with 171 patients who underwent laparoendoscopic single-site surgery for diverse urologic diseases in a single institution. MATERIALS AND METHODS Between December 2008 and August 2010, we performed 171 consecutive laparoendoscopic single-site surgeries. These included simple nephrectomy (n=18; robotic surgeries,(More)
PURPOSE To identify size criteria for complex cystic renal masses that can distinguish renal cell carcinoma from benign cysts supplementing the Bosniak classification. MATERIALS AND METHODS We reviewed the records of 97 patients who underwent surgery for complex cystic renal masses from January 2001 to April 2010. The pathological results were compared(More)
OBJECTIVES To describe our experience with robot-assisted laparoendoscopic single-site surgery (LESS) to perform partial nephrectomy and evaluate a hybrid homemade port system as an effective access technique. METHODS From December 2008 to September 2009, robot-assisted LESS to perform partial nephrectomy through a hybrid homemade port was performed to(More)
PURPOSE To describe our experience with robot-assisted laparoendoscopic single-site (R-LESS) surgeries and evaluate a homemade port system as an effective access technique. PATIENTS AND METHODS Between May 2009 and April 2010, 68 consecutive R- LESS urologic operations were performed in our institution. A 4 to 5 cm long incision was made over the(More)
PURPOSE To evaluate the impact of adjuvant chemotherapy (AC) in patients with upper tract urothelial carcinoma and lymphovascular invasion (LVI) after radical nephroureterectomy (RNU). MATERIALS AND METHODS We retrospectively analyzed the clinical records and clinicopatholgic outcomes of patients (n=552) treated with RNU between 1986 and 2013. Patients(More)
The goal of this study was to compare the diagnostic use and safety of endorectal coil (ERC) MRI with those of phased-array coil MRI. We retrospectively included 91 consecutive patients who had undergone 1.5-T MRI with ERC or with phased-array coil MRI before radical prostatectomy at our institution. We compared 47 patients’ phased-array coil MRI and 44(More)
The present experiments were conducted to investigate effects of α-amino-3-hydroxy-5-methyl-4-isoxazoleprionic acid (AMPA)/kainate receptor blockade (CNQX, NBQX) on locomotor responses to D2/3 (7-OH-DPAT) and D1 [(+)-SKF 38393] dopamine receptor agonists in the nucleus accumbens (NAS) core and shell. CNQX (0.25–0.5 µg) microinjected into the NAS core or(More)
Remote ischemic preconditioning (IP) is a potential renoprotective strategy. However, there has been no demonstrated result in large animals and the role of time window in remote IP remains to be defined. Using a single-kidney porcine model, we evaluated organ protective function of remote IP in renal ischemia reperfusion injury. Fifteen Yorkshire pigs, 20(More)
To increase the rate of living kidney donation, the long-term safety of nephrectomy must be demonstrated to potential donors. We analyzed long-term donor outcomes and evaluated the standardization of surgical technique. We evaluated 615 donors who underwent Video-assisted minilaparotomy living donor nephrectomy (VLDN) at Yonsei Severance Hospital between(More)
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(More)
