Abstract
Between 1970 and 1985, 10 male newborns with a contained urinoma were treated at our institution. An underlying congenital obstructive uropathic condition was discovered in every patient, the most common of which was posterior urethral valves. All 10 patients underwent surgical correction of the primary obstructive process. Direct drainage of the urinoma was required in 4 patients because of progressive clinical symptoms. Radiographic and renal functional parameters returned to normal at followup. Clinical presentation, evaluation, treatment and pathophysiology of this rare entity are discussed.
