Lithotripsy for Calculi in Caliceal Diverticula?

Abstract
There is continuing debate about the optimum management of patients with calculi in caliceal diverticula. Extracorporeal piezoelectric lithotripsy (EPL) has the advantage of being non-invasive, whereas endourological management can treat the underlying anatomical problem. A total of 20 patients with calculi in caliceal diverticula were treated with EPL. Twelve of 16 patients with symptoms (755) were rendered symptom-free but only 5 (25%) became stone-free. This information should be of value in counselling patients before selecting the appropriate treatment.
