[New technologies as an alternative to standard approaches to diagnosis and treatment of limited pyo-destructive diseases of the kidneys and perirenal space].

The authors analyze their personal observations of 76 patients with limited pyo-destructive diseases of the kidneys and perirenal space and describe the results of a minimally invasive method of treatment of this category of patients. Positive results were noted in 94% of the patients. The absence of complications, low lethality (1.5%), technical simplicity allow this method to be considered as the most adequate to modern requirements.
