Cumulative sum analysis of the learning curve for retrograde intrarenal stone surgery in newbie surgeons.

Introduction: This study investigated the learning curve of retrograde intrarenal surgery (RIRS) in patients with medium-sized stones using cumulative sum analysis (CUSUM) to evaluate the competence and proficiency of three new surgeons during their first RIRS procedures.

Materials And Methods: We conducted a retrospective review of 227 patients from 2019 to 2022 at a single institution. The patients were divided into four groups based on the operating surgeon: tutor surgeon (85 patients), newbie surgeon A (21 patients), newbie surgeon B (85 patients), and newbie surgeon C (36 patients).

Catheter-associated urinary tract infections in patients who have undergone radical cystectomy for bladder cancer: A prospective randomized clinical study of two silicone catheters (clinical benefit of antibiotic silicone material).

Purpose: The prevalence of catheter-associated urinary tract infections (CAUTIs) varies from 5% to 8.2%, and the risk of infection increases by 5% to 7% per day of primary indwelling. We investigated whether a novel biofilm inhibitory mechanism using an inhibitory silicone urethral catheter (a coated Foley catheter) can reduce CAUTIs compared to conventional non-coated Foley catheters.

A Comparison of the Anesthetic Methods for Recurrence Rates of Bladder Cancer after Transurethral Resection of Bladder Tumors Using National Health Insurance Claims Data of South Korea.

Bladder cancers have high recurrence rates and are usually removed via transurethral resection of bladder tumor (TURBT). Recently, some reports showed that the anesthetic method may affect the recurrence rates of bladder cancers. The purpose of this population-based study was to compare the effect of anesthetic methods with the recurrence rates of bladder cancers in South Korea.

Epidemiologic study of bladder and urethral injury in Korea: A nationwide population-based study.

Purpose: We aimed to analyze the characteristics and management of bladder and urethral injuries in Korea by use of the National Health Insurance Service (NHIS) database.

Materials And Methods: Data from the NHIS database representative of all cases of Korean bladder injury (n=4,631) and urethral injury (n=17,858) reported between 2012 and 2016 were analyzed. We used the International Classification of Diseases, 10th revision, clinical modification codes to identify the diagnoses.

The clinical impact of strict criteria for active surveillance of prostate cancer in Korean population: Results from a prospective cohort.

Purpose: To evaluate the clinical impact of strict selection criteria for active surveillance (AS) of prostate cancer in a Korean population.

Materials And Methods: A single-center, prospectively collected AS cohort from December 2016 to February 2019 was used. Following pre-determined criteria, patients were categorized into "strict AS" and "non-strict AS" groups.

Health-related quality of life after radical cystectomy.

Herein, we review the assessment of quality-of-life (QoL) in radical cystectomy (RC) patients, summarize the result of studies for different surgical approaches, and provide an overview of patient management, as well as other considerations. In this review article, we reviewed the QoL research and research tools for patients undergoing RC, including urinary diversion methods, gender differences, and surgical methods (open surgery robotic surgery). This narrative review focused primarily on articles indexed in PubMed, Embase, Scopus, and Google Scholar databases.

Cognitive Function and Urologic Medications for Lower Urinary Tract Symptoms.

Special considerations should be made when selecting medications for the treatment of lower urinary tract symptoms (LUTS) in older patients especially those over 65 years old. This review summarizes the relationship between current treatments for LUTS and cognitive impairment. Although the recently reported association between dementia and tamsulosin is debatable, the effects of α-blockers and pharmacokinetics are not reported in this context.

Current perspectives on novel systemic therapeutic agents beyond immune checkpoint inhibition in metastatic urothelial carcinoma.

Treatment strategies for metastatic urothelial carcinoma (mUC) have evolved dramatically over the last decade. The emergence of immunotherapeutic agents, especially immune checkpoint inhibitors, has been the most significant development. Immunotherapy increased the overall survival rate of patients with mUC and provided a durable response.
