PURPOSE: To report our surgical technique and initial experience with robot-assisted laparoscopic radical cystectomy (RARC) with total intracorporeal urinary diversion compared with an extracorporeal method. SUBJECTS AND METHODS: In total, 42 patients underwent RARC by a single surgeon at our institute for clinically localized bladder cancer. Among these, 4 patients underwent RARC with complete intracorporeal urinary diversion. An ileal conduit was achieved in 3 patients, and an orthotopic neobl

Purpose: The aim of this study was to compare the perioperative outcomes of patients who underwent single-port (SP) robot-assisted radical prostatectomy (RARP) (SP-RARP) with those who underwent multiport (MP) RARP (MP-RARP). Methods: Data on 40 consecutive patients who underwent SP-RARP between June 2020 and February 2021 and 129 who underwent MP-RARP between June 2019 and February 2021 were retrospectively reviewed. Using logistic regression, 31 patients who underwent SP-RARP were matched to 3

PURPOSE: To report short-term retrospective perioperative and pathologic outcomes of the first robot-assisted radical cystectomy (RARC) series in Korea. PATIENTS AND METHODS: Between April 2007 and August 2009, 104 nonconsecutive patients, including 22 women, underwent RARC across seven institutions. We evaluated the outcomes in these cases, including operative variables, hospital recovery, pathologic outcomes, and complication rate. RESULTS: The mean age of all patients was 63.6 years (range 39

Our study showed that the robotic virtual reality simulator (dV-Trainer) can yield sufficient improvement in technical performance in the "Tube 2" task within 4 hours. The simulator improves the technical surgical performance, but the development of more applications to reflect actual surgical situations is needed to improve and maximize the usefulness of the simulator.

Robotic radical prostatectomy (RARP) is a standardized treatment for localized prostate cancer, which provides better functional outcomes and similar oncological outcomes compared to open approaches. Here, we share our experience of 12,000 RARPs by describing the outcomes of the procedure in terms of positive surgical margin (PSM), continence, and potency as well as by presenting our detailed surgical technique with recent modifications. On cancer control, the PSM rates were 5.8% and 26.1% in T2

Udenafil is a potent novel phosphodiesterase-5 inhibitor approved for use in Korea. Udenafil has unique properties, with a T max of 1.0-1.5 h and a T 1/2 of 11-13 h (a relatively rapid onset and a long duration of action). Therefore, both on-demand and once-daily use of udenafil have been reported. Udenafil's efficacy and tolerability have been evaluated in several studies, and recent and continuing studies have demonstrated udenafil's promise in both dosing regimens. Presently, tadalafil is the

BACKGROUND: To compare the superiority of teaching methods for acquiring a proficient level of surgical skill in a robotic surgery-naïve individual using a robotic virtual reality simulator. METHODS: This study employed a prospective, randomized study design to assess student's learning curve. We divided 45 subjects into 3 groups: those with expert proctoring (group I), those who watched only an educational video (group II), and those with independent training (group III; n = 15 per group). The

Abstract This study aimed to investigate the effect of intraoperative fluid volume on the postoperative ileus (POI) recovery period. A retrospective review of the Korean robot-assisted radical cystectomy database identified 718 patients who underwent robot-assisted radical cystectomy (RARC). Regression analyses were performed to identify the associations between the amount of intraoperative fluid administration (crystalloid/colloid/total), POI period (time to flatus/bowel movements), and length

OBJECTIVES: To investigate the oncological significance of a robot-assisted radical cystectomy (RARC)-related pentafecta in patients with bladder cancer. PATIENTS AND METHODS: Using the KORARC database, which includes data from 12 centres, data from 730 patients who underwent RARC between April 2007 and May 2019 were prospectively collected and retrospectively analysed. Pentafecta was achieved if patients met all of the following criteria: (i) negative soft tissue surgical margin; (ii) ≥16 lymph

MicroRNAs (miRs) are small noncoding RNAs that have been reported to be promising diagnostic tools. We used quantitative real-time reverse transcription PCR (RT-qPCR) to analyze differentially expressed miRNAs in prostate tumor samples to determine its prognostic value. From 2007 to 2009, tumor tissues were obtained from 73 radical prostatectomy specimens. Differentially expressed miR-96, -145 and -221 were validated by TaqMan RT-qPCR using all 73 tissues. The prognostic value was assessed in te

Pheochromocytoma of the urinary bladder is an unusual tumor that typically presents with hypertensive crises related to micturition. We report here an unusual case of bladder pheochromocytoma that was treated by robotic-assisted laparoscopic partial cystectomy. A 35-year-old male patient presented with headache and hypertension related to micturition. The patient, who had a 3.5 × 4 cm solitary bladder tumor in the bladder dome, underwent robot-assisted partial cystectomy. The whole procedure was

Sedation may result in reduction in pain during transrectal ultrasound (TRUS)-guided prostate biopsies. We aimed to evaluate the efficacy and safety of a combination of propofol and remifentanil infusion during TRUS-guided prostate biopsy and the related increases in health care costs. From January to September 2010, 100 men undergoing a transrectal prostate biopsy were randomized into two groups. In Group 1, 50 patients received a combined infusion of propofol and remifentanil; in Group 2, 50 p
