| Extracorporal shock wave lithotrypsy (ESWL) | |

|
Big as well as small stones
can be fragmented by ESWL before
extraction. The example shows
a 7 mm calculus in the left
hepatic bile duct adhering
tightly to the ductular
wall. Neither an extraction
device nor a guide wire could
pass the concrement.

Extracorporal shock wave lithotripsy achieved a fragmentation of the stone. The fragments show as filling defects behind the target crosslines. Lavage with physiologic saline washes the debris out of the hepatic duct. |
