'Too Good to be True'? Ultrasound Safely Treats Kidney Stones
-
Treatment with transcutaneous, focused ultrasound safely led to the repositioning and rupture of a majority of stones in the urethra when tested in 29 people at two US centers in the first human feasibility study of the technology. This is the first human trial in awake subjects of this method for nonsurgically facilitating ureteral stone clearance, and the results of limited patient discomfort and stone motion in 66% of treated patients seem almost too good to be true
