Pre-ureteroscopy stent insertion and post-ureteroscopy sepsis

In an article by Nevo et al published in BJUI published in July 2017 the authors discuss the risk of sepsis in patients pre-stented before ureteroscopic stone surgery. Patients often have a ureteric stent inserted before ureteroscopic to enable surgery, however a stent can increase the risk post ureteroscopy infection. The authors conclude that the infection risk is similar between stent end and non-stented patients unless the stent is left for more than a month, when infection rates increase. The sepsis rates were 1, 4.9, 5.5 and 9.2% for stent dwell durations of 1, 2, 3 and >3 months respectively.
