The SAV value is an independent predictor of the success of ESWL and a useful tool for planning stone treatment. Patients with a SAV P956 HU are not ideal candidates for ESWL. The inclusion criteria for ESWL of stones with a SAV <500HUcan be expanded with regard to stone size, site, age, renal function and coagulation profile. In patients with a SAV of 500–1000 HU, factors like a body mass index of >30 kg/m2 and a lower calyceal location make them less ideal for ESWL. ª 2014 Production and hosting by Elsevier B.V. on behalf of Arab Association of Urology.
