Microscopic structure of renal dysplasia in a man with ectopic ureter opening into the seminal tract.
Histologically, we examined a dysplastic kidney obtained from a patient with an ectopic ureter opening into the seminal tract. The dysplastic kidney did not have any normal renal tissue or typical primitive ducts but epididymis- and prostate-like ducts. The last ducts contained degenerating spermatozoa in the lumen. The presence of epididymis- and prostate-like ducts is considered to be characteristic of dysplastic kidneys in this anomaly.
