[Demonstration of a fornix rupture in a newborn using 99mtc-mag3 kidney function scintigraphy].

In male newborns posterior urethral valves are the most frequent cause of subpelvine obstructions. A male newborn had to be delivered by caesarian section in the 36th week of pregnancy due to a progressive intrauterine hydronephrosis and excessive bladder filling. The condition could temporarily be normalized by catheterisation. However, following removal of the catheter on day 5 after birth an acute deterioration in the patient's general condition occurred due to an urine ascites. Scintigraphy using 99mTc-MAG3 led to the assumption that the cause was a fornix rupture in VURD syndrome (syndrome of posterior urethral Valve, Unilateral vesicorenal Reflux and renal Dysplasia), subsequently confirmed radiologically.
