Artificial intelligence in endourology: emerging technology for individualized care.

Curr Opin Urol 2022 Jul 31;32(4):379-392. Epub 2022 Jan 31.

Department of Urology, UT Southwestern Medical Center, Dallas, Texas, USA.

Purpose Of Review: Artificial intelligence in medicine has allowed for efficient processing of large datasets to perform cognitive tasks that facilitate clinical decision-making, and it is an emerging area of research. This review aims to highlight the most pertinent and recent research in artificial intelligence in endourology, where it has been used to optimize stone diagnosis, support decision-making regarding management, predict stone recurrence, and provide new tools for bioinformatics research within endourology.

Recent Findings: Artificial neural networks (ANN) and machine learning approaches have demonstrated high accuracy in predicting stone diagnoses, stone composition, and outcomes of spontaneous stone passage, shockwave lithotripsy (SWL), or percutaneous nephrolithotomy (PCNL); some of these models outperform more traditional predictive models and existing nomograms.

Authors:
Manzoor Hussain

J Pak Med Assoc 2021 Oct;71(10):2407-2414

Sindh Institute of Urology and Transplantation (SIUT), Karachi, Pakistan.

There is very little published literature on urologic diseases prior to 1947 from areas now constituting Pakistan. From inception of the country to 1970s, urology was part of surgery practiced by general surgeons except for two urology units established in 1960s. The real take off of urology began with introduction of transurethral resection of prostate (TURP) in 1980s, ushering the era of endourology; the second era of which began with ureteroscopy along with extracorporeal shockwave lithotripsy (ESWL) in 1987-1989, percutaneous nephrolithotomy in 1992 and introduction of percutaneous nephrostomy in 1997.
