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.
ESWL monotherapy is safe and effective method for treatment of bladder stones with no other causes of infra-vesical obstruction. Several indications can be met including patients with high anaesthetic risk, patients fearing anaesthesia or endoscopic procedures, and patients who have difficulty in positioning. 2016 Arab Association of Urology.

Time to lithotripsy is strongly associated with SFR followingSWL. SWL in an urgent care setting does not improveSFR if it is performed within 1 month, while time toSWL > 2 months reduces the likelihood of stone-free status.
The purpose of this article is to emphasize some important aspects on how SWL best should be used. Based on decades of experience, it stands to reason that success with SWL does not come automatically and attention has to be paid to all details of this technique.
