Prenatal drainage of fetal urinoma with polyhydramnios: a case report and literature review.

The appearance of fetal urinoma is rare in prenatal care, especially when associated with polyhydramnions. Many previous reports have concluded that the visualization of a prenatal urinoma is probably a sign of underlying renal dysplasia or poor function. Thus, the management of the reported cases, conservative treatment or uniroma drainage, has not been unified. In this paper, we present two cases of prenatally detected urinoma with prenatal drainage to improve the prognosis.
