　われわれは，最近あいついで多発性尿管憩室の2例を経験したのでここに報告する。

Case 1 : 73 year-old man with BPH complained urinary frequency and sense of residual urine, and intravenous urography revealed the right ureteral diverticula.

Case 2 : 44 year-old man with bilateral renal stones, bilateral multicystic kidney and retrocaval ureter complained microscopic hematuria, and retrograde pyelography revealed the left ureteral diverti-cula.

Sinse we could not deny papillary tumor in Case 1, partial ureterectomy was performed.

Histrogically, characteristic inflammatory changes were not seen in the diverticula which had no muscle layer.
