[Urinoma in newborn infants complicating congenital uropathy. 4 cases].
The authors report about four cases of urinoma detected during the neonatal period in three boys and one girl with congenital uropathy. It appeared as an infravesical obstruction in three cases (2 posterior urethral valves, one anterior urethral diverticulum) and as an obstruction of the pyeloureteral junction in the last case. The examination was prompted by the detection of a mass in the side during the clinical examination. The diagnosis is based on ultrasound, which evidences the liquid and extrarenal character of the urinoma and often allows demonstrating the underlying uropathy. The kidney may be difficult to localize if the urinoma is very large. IVP or radionuclide scanning may contribute to the diagnosis as they allow assessing the functional value of the kidney. The urinoma protects the kidney from the consequences of uropathy by allowing a relative decompression of the pyelocaliceal structures.
