[Unilateral external ectopia of the male monoureter]

It is reported on the very rare clinical picture of a unilateral ectopy of the ureter in the male sex. Since about one third of all infantile malformations are of urological nature in the occurrence of a relapsing epididymitis/orchitis in childhood and adolescence, connected with the rectal palpation findings of a soft cell in the region of prostate gland and seminal vesicle which can be squeezed out, should be thought of such a clinical picture. An early recognition in good time prevents an atrophy of testicle and epididymitis or even their loss, connected with later infertility.
