Vascular obstruction of the superior renal calyces in children.
The authors describe 5 cases with a pathology peculiar to the superior calyces due to vascular compression, observed from 1969 to 1975 among 938 urographic tests performed in the Pediatric Clinic of Florence. Three of these cases have been checked up to this date. In every patient the urographic tests show clear evidence of a vascular compression at the level of the right upper calyces, associated with stasis and/or ectasis. In two cases there is a symptomatology of abdominal pains; in the remaining 3 patients haematuria is revealed. It is important, particularly in children, to follow the course of the clinical and urographic features, in order to carry out a surgical intervention at the right moment, according to the evolution of the process. The chronic segmental (upper pole) pyelonephritis is the most dangerous evolution.
