Indwelling Ureteral Stents Cause Obstruction and Induce Injury and Fibrotic Changes

Ureteral stenting causes symptoms, including pain and discomfort, in > 80% of patients. Unfortunately, progress to prevent this significant morbidity is slowed by lacking understanding of how the ureter responds to stents. Here we investigated global changes in ureters at the transcriptional, translational, and functional levels while stents are indwelling and following removal and recovery. The effects of erythropoietin (EPO) and a Gli1 inhibitor were assessed to study the impact of possible interventions. Ureters respond to stents similarly to an obstruction, including activation of pathways associated with hydronephrosis, fibrosis and kidney injury. This is driven by significant dilation and associated ureteral SM dysfunction. EPO and Tamsulosin induced mild favourable changes in SM physiology, suggesting that targeting specific pathways has the potential to address stent‐induced complications.
