DYNAMICS OF RENAL BLOOD FLOW INDEXES IN PATIENTS WITH URETERAL STONES DEPENDING OF METHODS POSTOPERATION DRAINAGE

Abstract

Purpose of the study was to investigate indicators of renal blood flow in patients with ureteral stones on a background retention changes in the upper urinary tract and the influence of different methods of postoperative drainage for the restoration of renal hemodynamics. PATIENTS AND METHODS. Were examined 77 patients with ureteral stones (mean age 47,5 ± 1,8 years). All patients with ultrasound and dopplerographic study determined the spectrum of the velocity of blood flow to the definition of the maximum (peak) systolic velocity (Vmax. c), end diastolic velocity (Vkd) resistance pulsatile index to remove ureteral stones and for 3-5 days after ureterolitoecstraction. RESULTS. 30 patients did not reveal violations of renal blood flow against changes distention of the upper urinary tract caused by ureteral stones. In these patients was statistically significant, it was found that the method of drainage, as well as the refusal of him, had no effect on renal hemodynamics (p> 0.2). In 47 cases were registered for renal blood flow. When postoperative care without drainage showed deterioration of renal hemodynamics. At moderate violations of renal hemodynamics of blood flow was restored the same way as when using ureteral catheter, or during the installation of the stent. It is proved that the expressed infringements of renal blood flow require a longer drainage of the upper urinary tract (p =0,03). CONCLUSION. Application dopplerographichod for determining violations of blood flow in the preoperative period in patients with ureteral stones can develop an appropriate method of drainage of the upper urinary tract in the postoperative period to prevent the development of inflammatory complications.
