[Multiple giant ureteral lithiasis].

Objectives: Ureteral calculi are usually small and arise from the kidney. The term 'giant' has been applied to ureteral stones that are more than 5 cms in length and/or 50 gms or more in weight. The low incidence of this condition prompted us to report this case.

Methods/results: Herein we describe a patient with multiple giant ureteral calculi with no evidence of underlying ureteral lesion, who required nephroureterectomy due to the damage caused to the renal unit by the obstructive uropathy. The literature is briefly reviewed, with special reference to the diagnostic and therapeutic aspects.

Conclusions: Giant ureteral calculi are uncommon. They may cause scanty urological symptoms and might therefore be missed. If undiagnosed, renal function may be compromised by the obstructive uropathy.
