Extracorporeal shockwave lithotripsy for renal calculi: an unusual cause of common bile duct stricture.

A 50−year−old white man with recent−on− set painless jaundice underwent endo− scopic retrograde cholangiopancreatogra− phy (ERCP). One year before he had been diagnosed with bilateral renal calculi and these were treated on the right side with ESWL (three sessions, 3000 shocks per session, 14 ± 26 kV). His last ESWL session had taken place 2 months prior to the on− set of jaundice. His laboratory results showed a cholestatic liver pattern and elevated lipase (136 U/l, normal range 7 ± 60 U/l). The serum calcium, amylase, car− cino−embryonic antigen, and CA 19 ± 9 levels were all normal.
