HALLAZGOS ULTRASONOGRáFICOS EN EL TRATAMIENTO ENDOSCóPICO DEL REFLUJO VéSICOURETERAL

the use of endoscopio treatment in children with vesicoureteral reflux (vur) requires ultra-sonographic controls. radiologists should be aware of common findings to evaluate them properly and thus avoid misdiagnosis. a retrospective review of medical records, surgical protocols and images of 50 children treated with endoscopio injection of deflux (dextranomer/hyaluronic acid copolymer) was conducted between years 2005 and 2008; 23 patients were discarded due to lack of controls. the following parameters were recorded: age, clinical diagnosis, location and type of injection, volume injected, time elapsed until the first control, ultrasonographic features, and excretory systems dilation. we analyzed 27 cases (45 refluxing kidney-ureter units, kuus); age: ranging from 8 months to 17 years; vur: 18 bilateral and 9 unilateral (6 right, 3 left). urétera! orifice injection (sting): 12 kuus; intramural distal ureter (hit): 6; combined technique: 27 deflux injected volume: 0.4 to 1.3 cc per each kuu. us control: from 1 week to 2 months post-procedure. display: adequate in 35 kuus (77.8%), regular in 9 kuus (20%) and poor in 1 kuu (2.2%). configuration: rounded in 30 kuus, lobular in distal ureter in 10 kuus, and mixed in 5 kuus. no evidences of excretory system dilatation: in 37 kuus (82.2%) and 8 cases with some degree of dilation (1 severe, symptomatic case).
