Urinoma secondary to ureteropelvic junction obstruction in the neonate. Presentation of a case and bibliographic review.

OBJECTIVE To analyze the management of prenatal urinoma and ureteropelvic junction obstruction (UPJO) postnatally by a case report and literature review. METHODS We report a case of an UPJO and urinoma in a newborn. After birth, renal function was absent, and nephrectomy was performed. The literature from 1985 to date has been reviewed. DISCUSSION By the analysis of the literature, we can observe mainly, that prenatally diagnosed urinoma and UPJO are managed conservatively. After birth, different attitudes have been carried out, independently of residual renal function, such as radical or reconstructive surgery, or conservative treatment. CONCLUSION Intrauterine management is not indicated. Urinary diversion is indicated in symptomatic cases secondary to renal trauma or endoscopic procedure. In non-functional kidney, nephrectomy is indicated.
