Endoscopic guided PCNL in the prone split-leg position versus supine PCNL: a comparative analysis stratified by Guy's stone score.

Can J Urol 2019 02;26(1):9664-9674

Section of Endourology, Division of Urology, Hospital das Clínicas, University of São Paulo Medical School, São Paulo, Brazil.

Introduction: The optimal patient positioning for percutaneous nephrolithotomy (PCNL) based on the complexity of stone burden is not yet defined. Thus, we aimed to evaluate the intraoperative parameters, effectiveness and complications of patients undergoing PCNL between the endoscopic-guided prone split-leg PCNL (ePSL) and the supine PCNL by stratifying patients according to Guy's stone score (GSS).

Materials And Methods: A retrospective chart review was conducted of patients undergoing PCNL at two high-volume tertiary referral centers. Read More

Simultaneous Bilateral Endoscopic Surgery (SBES) for Bilateral Urolithiasis: the Future? Evidence from a Systematic Review.

Curr Urol Rep 2019 Feb 21;20(3):15. Epub 2019 Feb 21.

Department of Urology, University Hospital Southampton NHS Trust, Southampton, SO16 6YD, UK.

Purpose Of Review: Urolithiasis is a disease of prevalence across the world and up to a quarter of patients present with multiple stones. Most procedures carried out in this scenario are staged; however, there is a growing body of evidence to suggest bilateral simultaneous (BS) procedures are safe. We performed a systematic review to investigate and evaluate the evidence for these procedures. Read More

The eye of the endourologist: what are the risks? A review of the literature.

World J Urol 2019 Dec 8;37(12):2639-2647. Epub 2019 Feb 8.

Service d'Urologie, Assistance-Publique Hôpitaux de Paris, Hôpital Tenon, Sorbonne Université, 4 rue de la Chine, 75020, Paris, France.

Purpose: During endourological procedures, the eye of the urologist is exposed to hazards such as contact with body fluids and irrigation solutions as well as laser injury, and X-ray radiation absorption. The resulting potential injuries and damages to the eye have not been summarily reviewed to date. The objective was to review the different risks of exposure to the eyes of urologists during endourological procedures. Read More
