CYTOLOGICAL CYCLE OF THE URINARY SEDIMENT AND ITS PARALLELISM WITH THE VAGINAL CYCLE

Abstract

A simple, rapid method adaptable to office or clinic practice of obtaining smears of the urinary sediment in [female] [female] is described. The advantages, with respect to speed and convenience of the patient, of the urinary smear over the vaginal smear are obvious. Characteristic changes in morphology and in numbers of the cells in the urinary sediment were related to various phases of the sexual cycle of [female] [female]. The changes observed in the smears of the urinary sediment parallelled those seen in vaginal smears obtained simultaneously from the same patients. The effect of estrogens on the urinary smear was found to be the same as the effect on the vaginal smear, as indicated by studies on castrated patients or on patients with primary amenorrhea.
