OBJECTIVE: To report a new technique of robot-assisted laparoscopic nephroureterectomy (RANU) using a hybrid port, as RANU has recently become a minimally invasive treatment option for upper tract transitional cell carcinoma (TCC). PATIENTS AND METHODS: Eleven consecutive patients underwent RANU by one surgeon. The first six patients were repositioned after the nephrectomy, from flank to lithotomy position, and the robot was re-docked for excision of the distal ureter and bladder cuff. The last

Based on our experience at a single-institution, robot system can be used both safely and efficiently in many areas of urologic surgeries including prostatectomy. Once this system is familiar to surgeons, it will be used in a wide range of urologic surgery.

Sunitinib, a VEGF blockade, is used to treat clear cell renal cell carcinoma (ccRCC). However, the anti-cancer treatment effects of sunitinib do not last long in ccRCC patients. Ginsenoside, a natural medicine extracted from ginseng, has been studied in cancer treatment and shown to have anti-tumor effects and low toxicity. We assessed cell viability and cell cycle analysis in ccRCC cell lines after treatment with ginsenoside and sunitinib. DNA damage was evaluated by measuring 8-OHdG levels and

What's known on the subject? and What does the study add? LESS‐NU may be an alternative minimally‐invasive treatment option for patients eligible to undergo laparoscopic surgery for upper urinary tract urothelial carcinoma. The true benefits of LESS‐NU remain to be determined and require randomized control trials in the future. Despite encouraging early findings, clinical trials still are warranted before this procedure is adopted widely, and longer follow‐up is needed to determine its oncologic

PURPOSE: We report the initial functional and surgical results of 200 robot-assisted laparoscopic radical prostatectomies performed at our hospital, and evaluate the efficacy and safety of this surgery. MATERIALS AND METHODS: Between July 2005 and July 2007, 200 patients underwent robot-assisted laparoscopic radical prostatectomy(RLRP). All cases were performed using the four-arm da Vinci(TM) robot system (Intuitive Surgical, Mountain View, CA USA). RLRP was performed by two surgeons. All operat

Over the past decade, the introduction of robotics in the field of medicine has provided a new approach to patients requiring surgery, and both its advantages and disadvantages are currently under study by many groups worldwide. The use of robotics has especially been considered by the urological community as a treatment option in radical prostatectomy. The current case report is one in which the da Vinci Surgical System, with fourth arm use was employed in radical prostatectomy. This case prese

PURPOSE: Laparoscopic partial nephrectomy is a treatment option for small renal masses. However, such time-consuming techniques such as tumor excision, hemostasis and intracoporeal suturing are still challenging procedures even for experienced laparoscopists. Incorporation of a robotic system would facilitate tumor excision, hemostasis and intracoporeal suturing. Herein, we review our technique and the short term outcomes for robot-assisted laparoscopic partial nephrectomy(RLPN). MATERIALS and M

PURPOSE: In this study, we detail our initial experience with robot-assisted laparoscopic radical cystectomy(RLRC) with ileal conduit urinary diversion(ICUD) and describe the stepwise surgical procedure. MATERIALS AND METHODS: Four men underwent RLRC with extracorporeal ICUD for muscle invasive bladder cancer. RLRC was performed by a single surgeon using the da Vinci(TM) robot system(Intuitive Surgical, Sunnyvale, USA) with four robot arms. The surgical specimen was extracted through the sub-umb

In this paper, we report our initial experience of robot-assisted laparoscopic radical cystoprostatectomy (RLRC) with an ileal conduit urinary diversion (ICUD). Our patient was a 59-year-old man presenting with a clinical T4 invasive transitional cell carcinoma of the bladder and prostate. A RLRC was performed with the da Vinci() robot system (Intuitive Surgical, Mountain View, CA), which has a total of seven degrees of motion (six degrees of freedom and grip), and EndoWrist (Intuitive Surgical)

Purpose: We analyzed the outcome of medical management for children with vesicoureteral reflux (VUR) and we determined the factors affecting the outcome. Materials and Methods: We retrospectively reviewed the records of 37 patients (56 kidneys) who were diagnosed with VUR between 1995 and 2004. All the patients were maintained on prophylactic antibiotics and had regular follow up. The subjects were stratified according to the grade of reflux at the time of diagnosis into the low grade group (gra

Extramedullary plasmacytoma is a rare malignancy, composed of plasma cell dyscrasias localized to an extramedullary site in the soft tissue. The great majority of extramedullary plasmacytoma occurs in the head and neck region, mainly in the upper respiratory tract and oral cavity. Extramedullary plasmacytoma arising in the kidney, termed a primary renal plasmacytoma, is a very rare malignancy. Primary renal plasmacytoma is not distinguished from a renal cell or transitional cell carcinoma using

We report here on our technique and outcomes of the first two cases of robot-assisted laparoscopic nephroureterectomy with a bladder cuff excision(RLNU). RLNU was performed on two female patients who both had a muscle invasive lower ureter tumor. For the first step, nephroureterectomy was performed in the lateral flank position. For the second step, bladder cuff excision and bladder repair were performed in a steep Trendelenburg position. The specimen was extracted through a 6 cm sized incision
