Abstract

The main post uretero-sigmoidostomy complications are stricture of the anastomosis, chronic infection and urolithiasis. In our institution the patients with ureterosigmodostomy undergo a follow-up protocol in which blood chemistry, ultrasonography, intravenous pyelography and C.T. are periodically performed. The aim of the present paper is to compare the accuracy of kidney sonography after diuretic stimulation with intravenous pyelography in the diagnosis of ureteral stenosis. Out of 91 patient with ureterosigmoidostomy 18 patients (34 kidneys) underwent intravenous pyelography, a basal U.S. and then a dynamic one at 5, 10, 15, 30, 45, 60, 90, 120 minutes after administration of furosemide 20 mg i.v. At basal U.S. 27 kidneys were normal and 7 showed a dilations. After diuretic stimulation we observed 16 normal kidneys, 16 dilated units and 2 intermittent hydronephrosis. Out of 16 dilated kidneys 6 became normal in 60 minutes. Out of 10 dilated units 3 were normal in 90 minutes (hipotonic), 2 were normal before 120 minutes (low grade obstruction) and 5 were dilated after 120 minutes (high grade obstruction). With intravenous pyelography we observed 27 normal kidneys and seven dilated units. Dynamic sonography have shown high sensibility (100%), specificity (88.8%) and accuracy (91%) in diagnosis of ureteral obstruction in to I.V.P. in the follow-up of this kind of divesion.
