impact of stone radiodensity on the outcome of extracorporeal shockwave lithotripsy for renal pelvic stones

To evaluate the outcome of extracorporeal shock wave lithotripsy [SWL] for solitary stones 12th rib compared to a SFR of 67.9% [19/28] if the stone radiodensity was < 12 th rib. Stone composition was available in 68.5% of treated patients [n=74], but no correlation was found between stone radiodensity and stone composition. On the Domier compact alpha machine, stone radiodensity alone does not predict lithotripsy treatment outcome for stones
