The Short- and Long-Term Anticipation of Prostate Cancer Incidence in Korea: Based on Social Aging Trends and Prostate-Specific Antigen Testing Rate during the Last Decade.

The current incidence of prostate-specific antigen (PSA) testing, which plays a crucial role in detecting prostate cancer (PCa) in an aged population, is low in Korea. Reflecting these epidemiologic characteristics, we estimated the short- and long-term incidences of PCa. A regression equation model was extracted based on two critical pieces of information: (1) the distribution of newly detected PCa cases in each age group of the 50s, 60s, 70s, and over 80s from a recent period (2006-2020), and (2) the PSA testing rate (PSAr) from the previous decade (2006-2016) for each age subgroup.

The Long-Term Impact of 5-alpha Reductase Inhibitors on the Development of Bladder Cancer and the Need for Radical Cystectomy: A Nationwide Observational Study.

Purpose: To investigate the long-term effects of taking 5-alpha reductase inhibitors (5ARIs) on the development of bladder cancer (BC) and the implementation of radical cystectomy (RC), a standard procedure for advanced BC.

Materials And Methods: From the National Health Insurance Sharing Service database, males aged over 40 years who underwent serum prostate-specific antigen testing from 2006 through 2017 were identified, which is required for the prescription of 5ARIs. The association between the administration duration of 5ARIs and the practice for BC was analyzed.

Patients were divided into two groups according to the presence of recognizable symptoms.

The learning curve for robot-assisted radical cystectomy with total intracorporeal urinary diversion based on radical cystectomy pentafecta.

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-associated blocks according to the operation order.

Preclinical evaluation of a regenerative immiscible bioglue for vesico-vaginal fistula.

Currently, there are no clinically available tissue adhesives that work effectively in the fluid-rich and highly dynamic environments of the human body, such as the urinary system. This is especially relevant to the management of vesico-vaginal fistula, and developing a high-performance tissue adhesive for this purpose could vastly expand urologists' surgical repertoire and dramatically reduce patient discomfort. Herein, we developed a water-immiscible mussel protein-based bioadhesive (imWIMBA) with significantly improved properties in all clinical respects, allowing it to achieve rapid and strong underwater adhesion with tunable rheological properties.
