title: Multiple ureteral diverticula: a possible radiographically demonstrable risk factor in development of transitional cell carcinoma.
abstract: Six cases of multiple ureteral diverticula are reported. Most were associated with urinary tract obstruction or stasis and infection. One-third had transitional cell carcinoma, a frequency similar to that reported in previous series. These diverticula are a radiographically demonstrable reflection of urothelial hyperplasia/metaplasia and may represent a risk factor for development of transitional cell carcinoma.
