Transitional Urology in Korea: Initial Insights Through a Cross-Sectional Study.

Purpose: In Korea, the field of transitional urology (TU) is in its nascent stages, with its introduction only beginning. This study aims to evaluate the existing state of TU prior to implementing a transition protocol, and to identify key areas of focus for the development of an effective transition protocol.

Methods: From June 1, 2021 to May 31, 2023, clinical data were retrospectively collected for patients who visited the adult urology or pediatric urology outpatient departments of this hospital and were aged 10 or older, with medical conditions falling under the category of TU.

Predicting Urinary Stone Composition in Single-Use Flexible Ureteroscopic Images with a Convolutional Neural Network.

Analysis of urine stone composition is one of the most important factors in urolithiasis treatment. This study investigated whether a convolutional neural network (CNN) can show decent results in predicting urinary stone composition even in single-use flexible ureterorenoscopic (fURS) images with relatively low resolution. This study retrospectively used surgical images from fURS lithotripsy performed by a single surgeon between January 2018 and December 2021.

An Analysis of Major Causes of Surgical Failure Using Bähren System in Intraoperative Venography During Varicocelectomy.

Purpose: In young patients with varicocele, preservation of the internal spermatic artery may be advantageous for catch-up growth, but it may also increase the likelihood of treatment failure. Intraoperative venography reduces the likelihood that unsealed veins will remain after varicocelectomy. We analyzed the characteristics of remnant veins visualized through intraoperative venography to investigate the cause of surgical failure in artery-sparing varicocelectomy (ASV).

Comparison of prostate cancer detection rates of various prostate biopsy methods for patients with prostate-specific antigen levels of <10.0 ng/mL in real-world practice.

Purpose: Several strategies of prostate biopsy (PBx) have been introduced to improve prostate cancer (PCa) detection rates. However, studies comparing cancer detection rates (CDRs) according to biopsy methods in real-world practice are scarce. This study aimed to investigate CDRs according to the biopsy methods for patients with prostate-specific antigen (PSA) <10.
