STENT Overview


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 objecctive:

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.
