Based on the widespread incidence of acute pyelonephritis, which is one of the most common inflammatory diseases of the urinary system, it is important to conduct searching for improved treatment methods, which would ensure higher effectiveness of clinical regression of the process and minimize the extent of manipulations and pharmacotherapy. Pyelovesical bypass is one of these methods. The aim of this study is to investigate the efficacy of pyelovesical drainage of the urinary tract in the course of acute pyelonephritis in comparison with conservative methods of treatment in order to identify its advantages and disadvantages. To assess the effect of urinary tract drainage, we analyzed the clinical findings of patients with acute obstructive pyelonephritis, who underwent pyelovesical stenting and compared them with standard conservative treatment methods. According to the data obtained, we can conclude that pyelovesical stenting procedure in cases of acute obstructive pyelonephritis provides a statistically significant acceleration of the regression of clinical manifestations of kidney inflammation, such as hyperthermic reaction, pain syndrome, inflammatory changes in the blood and urine, parameters of ultrasonic dynamics. Thus, in the presence of clinical indications, appropriate technical conditions, devices and qualified surgeons to perform stenting, we can recommend this method as an effective means of integrated treatment for this renal pathology.
