[Ultrasonic study of the urinary system in hemophiliacs]

Ultrasonic investigation of the urinary system and the kidneys has been performed in 40 hemophilia A patients. The size of the kidneys was reduced in the majority of patients, the area of the calices in relation to relevant parenchyma was relatively enlarged. Parenchyma to caliceal-pelvic system ratio made up 1.5:1. The caliculi and pelves were dilated. The resultant ultrasonic picture was characteristic of chronic pyelonephritis. Concrements of the right and left kidney were detected in 45% and 62.5% of the patients, respectively. The bladder looked asymmetric with thick walls and echogenic particles in the cavity. Control laboratory findings failed to reveal any renal pathology. It is clear that diagnostic ultrasound is important in hemophiliacs who may develop latent renal disorders. The risks of replacement therapy with blood preparations and sequela of renal hemorrhages are considered.
