[Preclinical diagnostics and correction of the disturbed renal blood flow in the children presenting with diabetic nephropathy].

The present study included 86 children aged between 7 and 17 years with type 1 diabetes mellitus from 1 to 15 years in duration. In all the patients, renal blood flow was investigated with the use of ultrasonic dopplerography. The results of the study suggest disturbances of intrarenal hemodynamics that manifested themselves as enhanced resistance of renal arteries from periphery to the centre in the patients at the hyperfiltration stage of diabetic nephropathy (DN) in conjunction with the reduced velocity of blood flow in inter-lobular and segmental arteries. In contrast, the patients at the microalbuminuric stage of diabetic nephropathy exhibited increased resistance and reduced velocity of blood flow in the main renal veins. In 35 patients presenting with diabetic nephropathy, hemodynamic correction was achieved by the application of the traveling pulsed magnetic field (TP-MF) to the renal region using an AMO-ATOS-E apparatus (Russia). This treatment resulted in normalization of the characteristics of renal blood flow. It is concluded that TPMF has good prospects for the use as a component of the combined treatment of diabetic nephropathy.

[Intravesical electrostimulation and magnetotherapy in chronic pyelonephritis and cystitis in children with urodynamic disorders].

The results of the treatment of 38 children (6 boys and 32 girls, age 6-14 years) with chronic pyelonephritis and/or cystitis complicated with neurogenic dysfunction of the urinary bladder (NDUB) and/or vesicoureteral reflux (VUR) of the first-third degree demonstrate efficacy of intravesical electrostimulation (IVES) and adrenal magnetotherapy. IVES was conducted with high-frequency current impulses (2.2 kHz) by means of INTRASTIM attachment to the device AMUS-01-INTRAMAG in the region of the urethrovesical anastomosis via solution of the drugs for instillation. As the result of exposure to both physical factors in the presence of standard medication, NDUB symptoms alleviated (by E.L. Vishnevsky's criteria) by 59.5% against 38.1% in the control group. Dopplerographic examination of renal vessels stated a 24.3% increase in blood flow in the major renal artery in the study group against 10.5% in the control. The proposed complex pharmacological plus physiotherapeutic treatment of chronic pyelonephritis and cystitis in abnormal urodynamics resulted in a 2.2-fold decrease in the number of recurrences compared to the standard treatment.
