The management of urinary calculous disease in patients with duplicated ureters.

SUMMARY 
 
The anatomical and physiological peculiarities that contribute to difficulty in the diagnosis and management of calculous disease associated with ureteral duplication are illustrated by case examples from the author's experience with 20 patients treated over the last 10 years. In addition to the removal of the calculous or calculi, management must include the surgical treatment of urinary tract disease associated with ureteral duplication. Such surgical treatment will help to prevent the recurrence of calculi in these patients. A prolonged period of follow-up is necessary.
