Survey on ureTEric draiNage post uncomplicaTed ureteroscopy (STENT)

Published in BJUI 2020



The National Institute for Health and Care Excellence (NICE) and the European Association of Urology (EAU) guidelines encourage clinicians notto leave stents after uncomplicated ureteroscopies. Ureteric drainage practice internationally is variable. The published evidence alludes towards a high tendency of temporary ureteric stenting even after uncomplicated ureteroscopy (Hughes et al, 2014)(Auge et al, 2007). A recent Cochrane review on ureteral stenting after uncomplicated ureteroscopy reported desirable and undesirable effects of stents were small in absolute terms. All included studies had limitations. The Cochranereview identified a need to conduct higher quality sufficiently powered trials to answer this important question. (Ordonez M, 2019).


Aims and Objectives

Primary objective:

1. To assess the uncertainties about the feasibility of an interventional study assessing whether not stenting after uncomplicated ureteroscopy is superior to routine ureteric drainage (e.g. JJ stent or equivalent).
Secondary aims:
1. To understand current views and practice about ureteral stenting after uncomplicated ureteroscopy.

PERSIST: Perceptions, experiences and reflections of urologists on Stent Insertion after Stone Treatment



This was a project conducted with the CHART CTU in Aberdeen following an award at BAUS dragons den prize (supported by BAUS and TUF).


To understand the reasons why urologists unnecessarily insert stents after uncomplicated stone treatment in the UK and to design an intervention to ensure stents are used appropriately

Input and endorsements

PERSIST has been designed in close consultation with our Patient and Public Involvement (PPI) group, with consensus reached on outcome measures. PERSIST has also been recognized by GIRFT (Getting It Right First Time) as an important subject area that can inform and improve the delivery pathway for acute urinary tract stone management.
