[A Rare Cause of Perinatal Postrenal Failure with Megalourethra]. / Seltene Ursache eines Perinatalen Postrenalen Nierenversagens mit Megalourethra.

We present a case of a premature infant with a presumed obstructive uropathy found to be a megalourethra leading to a perinatal postrenal failure. A megalourethra - an uncommon cause of urethral dilatation - is a congenital, non-obstructive anomaly of the penile erectile tissue. We think that a distal stenosis resulted in dysplasia of the penile tissue and an aspect of a megalourethra. Further diagnostic workup included urinary tract sonograms, a voiding cystourethrogram and MAG3 scintigrafy. Initially the patient was managed with supportive care such as a suprapubic urinary catheter, followed by surgical intervention (Bengt Johanson).
