[The stimulation of ureteral motor activity by ultrasound in ureterolithiasis]

The paper presents methodological and therapeutic aspects of the experiment in which rabbit ureters were stimulated with ultrasound. Rectal exposure to the ultrasound made impulses from the ureteral smooth muscle significantly more frequent in 100% of the animals, applications of the ultrasound to the skin produced the same results in 70% of the test animals. The authors also achieved clinical effects in 63.6% and 86.7% of patients with ureteroliths or their fragments, respectively, in the low third of the ureter following combined treatment which involved oral mineral water, sodium chloride baths and ultrasound. The effect was evident after a single treatment course.
