Treatment of angiomyolipoma (AML) of kidney with stone has been challenging for urologists. We present our experience of treating the renal stone in the presence of AML with shockwave lithotripsy (SWL). Position of the patient with respect to the direction of the shockwaves and accurate knowledge of the dimension of the focal zone are critical aspects of SWL. Keeping the AML safely away from the focal zone at all times during the procedure is only possible by usage of real-time ultrasonography in lieu of fluoroscopy.

Hot stuff! They succeeded. The images show an AML of at least 4 cm diameter in a distance of approximately 4 cm to the stone. They do not describe how they made sure that the respiratory movements of the kidney did not bring the AML into the blast path.
