In an attempt to improve the diagnostic accuracyfor uterine cancer, especially endometrial carcinoma, an apparatus was developed to facilitate desquamation of endometrial cells by ultrasonic waves. Experimental results thereby obtained wereas follows:
1) As a basic experiment, this apparatus wasused on 15 cases of removed uterus, under thecondition of 40W, 28kHz, and oscillator amplitudeof 10μm. This was found to give satisfactory collection of the cells and no untoward effect on theuterine wall.
2) This method was applied as clinical diagnosison 30 cases and anticipated result was obtained, there being no discomfort of pain, hemorrhage, orother side effects.
