[Modern technologies in diagnosis and treatment of patients with late stages of hydronephrosis].

To evaluate the role of modern ultrasonic, x-ray and radionuclide methods in staging hydronephrosis; that of stimulators of stem cells of the bone marrow in combined therapy of patients with late hydronephrosis, we examined and treated 18 patients with late-stage hydro- and ureterohydronephrosis. All the patients were operated. Preoperative preparation included drainage of the upper urinary tract and stimulation of bone marrow stem cells. Organ-saving surgery was conducted with a satisfactory functional result in 14 of 18 patients. Modern methods of investigation provide an objective assessment of structural-functional condition of the kidneys and upper urinary tract in patients with late hydro- and ureterohydronephrosis, may evidence for possible reversibility of registered uro- and hemodynamic alterations. Preoperative use of stimulators of bone marrow stem cells promotes activation of repair processes in renal parenchyma which is essential for efficacy of a further reconstructive operation.
