The Degree of Hydronephrosis as an Indicator of the Necessity for Ureteric Dilatation during Ureteroscopic Lithotripsy.

During rigid ureteroscopic lithotripsy, it is often encountered that the ureter is difficult to access. Attempts to advance the ureteroscope make the surgery more difficult. This study evaluated the preoperative predictive factors associated with difficult ureteral access (difficult ureter (DU)) during URS and assessed if clinical outcomes differed according to the degree of DU.

What are the risk factors for recurrent UTI with repeated ESBL-producing Enterobacteriaceae? A retrospective cohort study.

Introduction: A previous study has shown that two-thirds of patients with urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae experience recurrence with the same bacteria on subsequent UTI episodes. However, little is known about which patients suffer from UTI due to ESBL-producing Enterobacteriaceae repeatedly. This study aimed to investigate the risk factors for recurrent UTI due to repeated ESBL-producing organism infections.
