The paper covers the experiment's details and the results obtained at stimulation of the kidney projection region and upper ureter with remote-controlled impulse magnetic field (IMF). It was found that IMF activates impulse activity of ureteral smooth muscles in 100% of cases. The technique is detailed of managing ureterolith fragments using IMF combined with iodobromine baths. The results of the proposed treatment are given. A single therapeutic course produced effect in 62.9% of the patients.
