PURPOSE: To compare the perioperative outcomes, postoperative complications, and early oncologic outcomes of intracorporeal urinary diversion (ICUD) with those of extracorporeal urinary diversion (ECUD) following robot-assisted radical cystectomy (RARC) performed by a single surgeon at a tertiary referral hospital. MATERIALS AND METHODS: We reviewed a prospectively maintained, institutional review board-approved database of 70 patients treated with RARC and pelvic lymph node (LN) dissection for

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

This multi-institutional cohort study demonstrated the benefits of the ICUD approach, as indicated by lower complication rates and better recovery parameters, although the oncological results were similar to those of ECUD.

We aimed to compare the short-term outcomes of men who had urodynamic evidence of detrusor underactivity (DU) or detrusor overactivity (DO) of a non-neurogenic etiology as well as bladder outlet obstruction (BOO) and who underwent Holmium Laser Enucleation of the prostate (HoLEP). A database of 322 patients who underwent HoLEP between 2010 and 2014 was analyzed. Patients were classified into three groups according to the results of a preoperative urodynamic study. Preoperative parameters such as

PURPOSE: We previously described a new procedure specific module (Tube 3) to allow the practice of vesicourethral anastomosis after robot-assisted radical prostatectomy. Herein, we report a predetermined proficiency level of Tube 3 and preliminary validation to explore whether this new module can lead to performance improvement in the da Vinci system. MATERIALS AND METHODS: Eight urology residents and three urology fellows performed the Tube 3 module 1 hour daily for 7 days. The learning curve w

Rate of complete PC in RCC is relatively low in this study. The risk factors for pseudocapsular invasion were a histologic diameter greater than 4cm, non-clear cell histology, and an incomplete PC. Surgeons must prepare for the possibility of a positive surgical margin if a tumor has at least one of these risk factors.

Purpose: To assess awareness of prostate cancer and prostate cancer screening in high risk Korean men 40 years and older. Materials and Methods: The Korean Urological Oncology Society implemented an online survey of 600 men aged 40 years or older from July 30 to August 6, 2019 to ask questions about prostate cancer and screening. Results: Of the 600 respondents, 96.5% (579 of 600) were aware of prostate cancer and 49.8% (299 of 600) thought they were at risk. Men in their 60s, men with a family

PURPOSE: To evaluate tumor-specific immunity and define the mechanisms involved in the cryoimmunologic response, we compared the tumor control efficacy and immunologic responses of cryoablation with those of surgical excision in a tumor rechallenge model. MATERIALS AND METHODS: Sixty BALB/c mice with RENCA tumors that were generated in the left flank area underwent cryoablation or radical excision. The mice successfully treated were rechallenged with RENCA or an undifferentiated colon carcinoma

RARC results in comparable oncological and functional outcomes to open radical cystectomy. In addition, the oncological and functional outcomes were well maintained throughout the learning curve. ECUD transition to ICUD was safe and did not compromise oncological or functional outcome.

Objective To analyze the learning curve for robot- assisted radical cystectomy (RARC) with total intracorporeal urinary diversion (ICUD) in terms of both time efficiency and quality of surgery based on radical cystectomy (RC)-pentafecta. Patients and methods We identified 203 consecutive patients who underwent RARC with ICUD of the ileal conduit (IC, 85) and orthotopic neobladder (ONB, 118) performed by a single surgeon between 2011 and 2021. We grouped ten consecutive patients into time-associa

Abstract To investigate the characteristics and impact of asymptomatic (silent) ureteral stones on renal function and compare them with those of symptomatic stones. We retrospectively reviewed the medical records of 677 patients who underwent ureteroscopic lithotripsy or laparoscopic ureterolithotomy for ureteral stones between 2016 and 2020. Patients were divided into two groups according to the presence of recognizable symptoms. We investigated the characteristics and impact of silent stones o

Medications recommended by the American Urological Association and the Sexual Medicine Society of North America were all incorporated within the present review, together with additional management approaches that have been evaluated in randomized controlled trials. The findings indicated that in addition to SSRIs, tramadol, clomipramine, topical agents and PDE5 inhibitors could be used in the therapy of PE.

The present results show that the complication rate reported by use of a standardized methodology after robotic radical cystectomy is still considerable although comparable to that of contemporary robot series. EBL, operative time, and diversion methods were predictors of complications.
