Young's syndrome accompanied by medullary sponge kidney.

A 33-year-old man was admitted to our division for further evaluation of repeated fever and purulent sputa of more than 10 years duration. Based on clinical symptoms, chest roentgenograms, bronchograms, seminal examination, testicular biopsy specimen and electron micrograph of cilia from the left main bronchial mucosa, the diagnosis of Young's syndrome was made. A drip infusion myelogram, which was performed because of a persistent hematuria, revealed bilateral medullary sponge kidney, suggesting the involvement of this hereditary disorder in Young's syndrome.
