To investigate the functional outcomes of ileal ureter replacement for complex ureteral loss, including bilateral and single ureter stricture, as a result of various etiologies.In 2013-2016, 31 patients underwent ileal ureter replacement surgery. The data for their assessments included etiology, combined surgical procedures, ureteral replacement type, postoperative complications, and changes in renal...
To determine, via a randomized comparison study, whether robotic simulator-acquired skills transfer to performance of a urethrovesical anastomosis (UVA) on a 3-dimensional-printed bladder model using the da Vinci Robot.Medical students, surgical residents, and fellows were recruited and divided into 2 groups: Group 1 (G1) (junior trainees) and Group 2 (G2) (senior trainees). Participants were randomized...
To evaluate population-based prostate cancer (CaP) testing of men in their 40s, given the paucity of prospective data evaluating the consequences of prostate-specific antigen (PSA) testing in younger men for CaP.A total of 1052 men in their 40s were followed longitudinally for prostate outcomes, from 1990 to 2010. A random subset of 268 men was selected to undergo biennial CaP testing including PSA...
To develop and validate a nomogram assessing cancer and all-cause mortality following radical cystectomy. Given concerns regarding the morbidity associated with surgery, there is a need for incorporation of cancer-specific and competing risks into patient counseling and recommendations.A total of 5325 and 1257 diagnosed with clinical stage T2-T4a muscle-invasive bladder cancer from January 1, 2006...
To investigate the relationship between irritable bowel syndrome (IBS) and overactive bladder (OAB) in men and women using questionnaires.This research survey was based on multicenter data (men and women older than 20 years). The Korean version of the Rome III criteria was used for the diagnosis of IBS, Overactive Bladder Symptom Score (OABSS) was used for screening OAB, Self-Rating Depression Scale...
To evaluate safety and feasibility in a first-in-human trial of a direct magnetic resonance imaging (MRI)-guided prostate biopsy using a novel robotic device.MrBot is an MRI-safe robotic device constructed entirely with nonconductive, nonmetallic, and nonmagnetic materials and developed by our group. A safety and feasibility clinical trial was designed to assess the safety and feasibility of a direct...
To determine the clinical value of visually assessed renal tissue transit time (TTT) in 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) renography for patients undergoing pyeloplasty.Medical records of 164 patients who underwent dismembered pyeloplasty were retrospectively reviewed. Baseline and postoperative renal ultrasonography and 99mTc-MAG3 renography were performed. Two urologists blinded to clinical...
To report on the establishment of a unified, electronic patient-reported outcome (PRO) infrastructure and pilot results from the first 5 practices enrolled in the web-based collection system developed by the Michigan Urological Surgery Improvement Collaborative.Eligible patients were those undergoing radical prostatectomy of 5 academic and community practices. PRO was obtained using a validated 21-item...
We sought to examine the risk of recurrent stress urinary incontinence (SUI) after suburethral sling mesh removal or excision.We conducted a retrospective cohort study of patients who were continent before removal or excision of synthetic midurethral slings; this cohort of 278 subjects was much larger than seen in previous such studies. Patients with preoperative incontinence, additional vaginal mesh...
To evaluate the safety and short-term efficacy of complete sacrocolpopexy mesh excision with concomitant autologous fascia sacrocolpopexy.A retrospective cohort study of patients undergoing complete sacrocolpopexy mesh excision and concomitant autologous fascia sacrocolpopexy from March 2013 to September 2016 was conducted. The primary objective was assessment of perioperative outcomes including complications...
To evaluate the surgical outcomes of female urethral diverticulectomy.We retrospectively analyzed the medical records of 68 patients with symptomatic urethral diverticula (UD) with at least 1 year of follow-up data following transvaginal urethral diverticulectomy conducted by a single surgeon. The presence of UD was confirmed by a preoperative magnetic resonance imaging (MRI). According to MRI findings,...
To describe distinctive morphologic variations of the prostate associated with the prostatic urethra, and to determine whether structural changes of the urethra within the prostate resulting from gland enlargement, rather than prostrate volume itself, lead to male lower urinary tract symptom (LUTS).After standardizing measurements, 7 ultrasonography-determined variables, that is, prostate volume,...
To evaluate the effect of listening to music on pain, anxiety, or stress during a urodynamic study (UDS).A total of 74 female and 74 male patients who underwent UDS between March 2013 and October 2013 were prospectively randomized. The patients were divided into 2 groups according to gender (female, n = 74 vs male, n = 74) and into 2 subgroups according to whether they listened to music or not. Music...
To evaluate the relationship between changes in weight, waist circumference (WC), metabolic syndrome (MetS), and prostate growth over 5 years in the adult population.Data were collected from 1088 adult men (age ≥40 years) without history of prostate cancer who underwent more than 2 general health screenings between 2006 and 2013. Percent changes in prostate volume (PV) were assessed for 5 years after...
To assess the negative predictive value (NPV) of multiparametric magnetic resonance imaging (mpMRI) for detection of prostate cancer (PCa) in routine clinical practice and to identify characteristics of patients for whom mpMRI fails to detect high-grade (Gleason score ≥7) disease.We reviewed our prospectively maintained database of consecutive men who received prostate mpMRI at our institution, interpreted...
To determine the added value of prostate magnetic resonance imaging (MRI) to the Prostate Cancer Prevention Trial risk calculator.Between January 2012 and December 2015, 339 patients underwent prostate MRI prior to biopsy at our institution. MRI was considered positive if there was at least 1 Prostate Imaging Reporting and Data System 4 or 5 MRI suspicious region. Logistic regression was used to develop...
