title: Urinary fungal bezoars in children--report of two cases.
abstract: We report two cases of urinary obstruction by fungal bezoars in full-term neonates who presented a uropathy detected antenatally. Early percutaneous urinary diversion was performed to relieve renal impairment secondary to a primary megaureter in the first case and to bilateral pelvi-ureteral obstruction in the second. Acute fungal obstruction occurred first on the side of the primary megaureter and then on the healthy side in the first patient. Symptoms of infection and impaired renal function led to a diagnosis of fungal bezoar. In the second patient the development of the bezoar was more insidious and occurred after surgical correction of the obstructive pelvi-ureteral junction on the left side. Candiduria was the first sign in both cases. Ultrasonography is the best method to visualize fungal masses within the collecting system. In most cases, percutaneous nephrostomy allows relief of the obstruction, sampling of urine for culture and irrigation with amphotericin B. However, additional surgical intervention may be necessary. Systemic antifungal treatment using mainly 5-flucytosine is also given.
