Finally, the doctor performs a rectovaginal examination by inserting the index finger into the vagina and the middle finger into the rectum. In this way, the back wall of the vagina can be examined for abnormal growths or thickness. A woman may be given a take-home kit to test for unseen blood in the stool. Occasionally, more extensive tests are needed. To examine the internal genital organs, doctors use various diagnostic tools, including instruments that apply fiber-optic technology.
Fiber optics are thin, flexible strands of plastic or glass that transmit light.
A fiber-optic cable attached to a viewing tube called a laparoscope can be used to examine the uterus, fallopian tubes, or ovaries without requiring a large incision. The laparoscope can also help doctors perform surgical procedures in the genital tract. All rights reserved.
