Objectives: To evaluate the risk of repeat surgery and stone-related events after flexible ureteroscopy (fURS) for renal stones, and to identify their predictive factors.

Patients And Methods: This was a single-center, retrospective cohort study of patients (n=664) who underwent fURS for renal stones with or without concomitant ureteral stones between January 2012 and December 2019. The primary outcomes were time to ipsilateral stone-related surgical intervention and any stone-related event (including ipsilateral renal colic, symptomatic ureteral calculi, obstructive urinary tract infection, and surgical intervention).

Insights Imaging 2021 Mar 3;12(1):30. Epub 2021 Mar 3.

Imadis Teleradiology, Lyon, Bordeaux, Marseille, France.

Objectives: To evaluate the impact of COVID-19's lockdown on radiological examinations in emergency services.

Methods: Retrospective, multicentre analysis of radiological examinations requested, via our teleradiology network, from 2017 to 2020 during two timeframes (calendar weeks 5-8 and then 12-15). We included CT scans or MRIs performed for strokes, multiple traumas (Body-CT), cranial traumas (CTr) and acute non-traumatic abdominal pain (ANTAP). Read More

We present a case of a woman affected by Systemic Lupus Erythematosus (SLE) and distal renal tubular acidosis (DRTA) that during pregnancy presented an exacerbation of SLE together with a renal colic with spontaneous stone passage. Radiological exam revealed diffuse calcifications in both kidneys which suggests, in a context of DRTA, a nephrocalcinosis. With the stabilization of SLE and medical treatment directed to correct metabolic alterations we achieved radiological and clinical stability of lithiasic disease. Read More

Departments of Emergency Medicine and Community Health Services, University of Calgary, 2500 University Drive NW, Calgary T2N 1N4, Canada. Electronic address:

Objectives: After initial emergency department (ED) management of acute renal colic, recurrent or ongoing severe pain is the usual pathway to ED revisits, hospitalizations and rescue interventions. If index visit pain severity is associated with stone size or with subsequent failure of conservative management, then it might be useful in identifying patients who would benefit from early definitive imaging or intervention. Our objectives were to determine whether pain severity correlates with stone size, and to evaluate its utility in predicting important outcomes. Read More

Emerg Radiol 2021 Mar 1. Epub 2021 Mar 1.

Department of Radiology, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.

Purpose: To evaluate the ability of a semi-automated radiomic analysis software in predicting the likelihood of spontaneous passage of urinary stones compared with manual measurements.

Methods: Symptomatic patients visiting the emergency department with suspected stones in either kidney or ureters who underwent a CT scan were included. Patients were followed for up to 6 months for the outcome of a trial of passage. Read More
