Multiple ureteral diverticula: report of 2 cases and review of the literature.

Multiple ureteral diverticula, probably acquired, are rare; they are most frequently diagnosed in elderly males and associated with infections of the urinary tract and prostatic hypertrophy. There is no definite treatment. On the other hand, one should be well aware of the possibly higher risk of transitional cell carcinoma. At least yearly urinalysis and cytology seem mandatory.
