To the Editor:—
The physician should suspect the presence of an ectopic ureter when a patient presents the complaint of continual dribbling of urine superimposed on micturition at normal intervals. This dribbling usually has its onset in infancy; it occurs primarily when the patient is in a vertical position and hence is usually diurnal in nature. The ureter is sufficiently flaccid to pool urine when the patient is recumbent, and the incontinence is effected by gravity when sitting or standing. Ectopic ureters oftenest arise from the upper pelvis of a double kidney, which embryologically is the result of formation of an accessory ureteral bud on the Wolffian duct. The distal end may open, in females, in the vestibule, the external meatus, the urethra, the vagina, and the uterus; in males, in the urethra, the ejaculatory ducts, and the seminal vesicles (Higgins, T.
