The primary findings show a small overall benefit for a-blockers as MET for ureteric stones but no benefit with CCBs. a-blockers show a greater benefit for large (>5 mm) ureteric stones and those located in the distal ureter, but no benefit for smaller or more proximal stones. a-blockers are associated with a greater risk of side-effects compared to placebo or CCBs. 2017 Production and hosting by Elsevier B.V. on behalf of Arab Association of Urology.

This study shows that determination of stone density and stone size on CT KUB pre ESWL can help to predict the outcome of ESWL. We propose that stone density <500 HU and stone size < 5 mm are highly likely to result in successful ESWL.
Double pigtail ureteric stent placement appears to be unnecessary in procedures considered ‘uncomplicated’ by operating urologists during surgery. The advantages of the double pigtail ureteric stent with extraction string over the double pigtail ureteric stent only include earlier and easier removal with earlier relief of symptoms, and less analgesia requirements.
