Single Site Robotic hysterectomy is the next step in the evolution of hysterectomies. We now have the ability to perform a hysterectomy (or cholecystectomy, or appendectomy) through a virtually scar less procedure. The Robotic Single Site procedure is performed through a 2.5 cm incision that goes directly through your belly button. This minimizes scaring and post operative pain. While better for the patient, it is technically more difficult for the surgeon to perform. Surgeons must receive specialized training, and already be proficient at performing Robotic hysterectomies. As the technology advances, we will be able to offer single site procedures to a greater variety of patients. Patient selection is currently limited by: the patient’s BMI, the size of her uterus, and other complicating factors (scar tissue, endometriosis, prior surgeries, etc.). Save Save
When making a concerted effort to get pregnant, an understanding of basic reproduction can help couples have more success. In order for pregnancy to occur, there must be an egg from the mom and sperm from the dad in the fallopian tube of the uterus at the same time. Once the egg and the sperm combine, that newly formed zygote has to be able to get into the womb in the interior of the uterus and implant into the wall of the uterus. Sounds simple enough, but the synchronized hormonal signals necessary to stimulate the production of an egg, release of that egg, and to prepare the uterus to receive a pregnancy can be a disrupted in some women. In other women, there may be a blockage in the passage from the fallopian tube to the interior compartment of the uterus which may prevent sperm from getting to the egg or the zygote from getting into the uterus to implant and grow. There is a high attrition rate for sperm as they navigate through the vagina, cervix, uterus, and finally the fallopian tube to meet the egg. While only one sperm is necessary to impregnate an egg, about 20 million […]
