A Rare Case: Bilateral Hydronephrosis Due to Bilateral Abdominoscrotal Hydrocele in an Infant

Abdominoscrotal hydrocele is a rare entity and first described by Dupuytren in 1834. Its etiology is still unclear. Rare complications are hydroureter/hydronephrosis, testicular flattening and malignant mesothelioma of tunica vaginalis associated with intraabdominal testis in an abdominoscrotal hydrocele. Herein we report a 7-month-old boy with bilateral abdominoscrotal hydrocele with secondary bilateral hydronephrosis due to contiguous pressure. Bilateral hydrocelectomies were performed. The postoperative course was uneventful without complication. Six month after the operation the renal ultrasound was normal. This entity, although unusual, should be considered in the differential diagnosis of a lower abdominal mass in children, as well as a cause of hydronephrosis. After surgical removal, healing is usually complete, including regression of the hydronephrosis.
