Ultrasonography in obstructive uropathy in infants

ABSTRACT

The study included 18 male patients aged 2mg. to 2 years, presented by vomiting, dehydration, abdominal distention, oliguria or even anuria. Rehydration by I.V. fluids and symptomatic treatment of vomiting and abdominal distension have improved the general condition of the patients but not the urine outflow. Blood urea and serum creatinine were elevated. Plain X-ray on the abdomen and IVU were done for all patients but were inconclusive. Abdominal ultrasonography revealed bilateral pelviureteric obstruction by radiolucent stones in 8 cases, bilateral ureteric dilatation without evident cause of obstruction in 2 cases, bladder outflow obstruction due to posterior uretheral valve in 6 cases and bladder neck obstruction in 2 cases Blood urea, serum creatinine and dilatation of the collecting system returned to normal within 4-10 days and 10-15 days respectively in 10 cases. While in8 cases improvement of such parameters occurred but not return to normal. Reduction of the thickness of renal cortex as well as focal increase in renal cortical echogenicity due to renal scarring was observed in this later group of patients by follow-up abdominal ultrasonography
