Ureteric Stents Compromise Stone Clearance After Shockwave Lithotripsy For Ureteric Stones: Results Of A Matched-Pair Analysis
UroToday.com - In this study, 45 patients with ureteric stents undergoing extracorporeal shockwave lithotripsy (ESWL) for ureteral calculi (77% in the proximal ureter) were matched to patients with similar size and location of stones albeit without stents. ESWL was performed on a Sonolith Vision lithotripter. Overall, a stone free state was achieved more commonly (odds ratio of 6.0, p < 0.016) if there was no stent (93% vs. 71% stone free rate with a stent in place)!
What is the take home message? First, stents should be placed whenever it is necessary to drain the obstruction either due to urosepsis or pain unrelieved by narcotics; however, in all other circumstances with ureteric stones < 1…
