[Ultrasonic diagnosis of radiation injuries of the urinary system]

The paper is concerned with the results of ultrasound investigation of the kidneys and bladder in 78 patients with radiation injuries of pelvic tissues and organs. Comparison of the results of USI, isotope renography and excretory urography has shown that with an increase in the gravity of injury of the urinary system, the frequency of ultrasound findings rises from 60.8% in renal dysfunction of a mean gravity up to 91.2% in severe disorders. Echography data on the presence of hydronephrosis, pyelocaliectasis, a granular kidney, pyelonephritis, and nephroptosis usually coincided with the results of excretory urography in these patients. A combined use of echography and renography permits obtaining in most cases necessary data on structural and functional disorders of the urinary tracts. Echographic semiotics of radiation cystitis was studied in detail versus cystoscopy data. The informative value of ultrasound scanning of the bladder was observed in patients with radiation cystitis.
