超音波検査が有用であった問漱性水腎症の2例

Abstract

Case 1: An 8-year-old boy consulted our clinic complaining of left flank colicky pain. He had a past history of the same episode. Ultrasonographic study was promptly performed. Left hydronephrosis was detected. At operation, left aberrant renal vessel was resected, and he has been free of pain. Case 2: A 65-year-old woman consulted our clinic because of abdominal pain and fever, who occasionally had the same episode. The existence and disappearance of the right hydronephrosis could be observed by emergency ultrasonography and following ultrasonic study, and the stenosis of the right lower ureter caused of cystitis cystica and glandularis was pointed out by retrograde ureterography. Diuresis ultrasonography by furosemide was performed to evaluate urinary tract stricture. In case 1, an incomplete obstruction pattern was obtained after operation, and in case 2, a complete obstruction pattern was shown. The emergency ultrasonography and diuresis ultrasonography were useful for the diagnosis and observation of intermittent hydronephrosis.
