Diagnostic methods gynecological

Gynecologists resorted to various methods of diagnostic aids in the consultation. Here are some of the employees more often.

Papanicolaou
In the box detailing what the most widespread and all necessary studies being conducted routine gynecologic consultation. Should be done once a year, from the time of onset of sexual relations.

Colposcopy
It is good practice to do next to the PAP. It is used for that purpose a device composed of a binocular and a light source of high intensity. With it you can see injuries at the cervical, vaginal cavity and the vulva.

Hormonal analysis
These studies, which are conducted through a blood-listed when there are disruptions of the menstrual cycle or difficulty achieving pregnancy. The baseline should be obtained by the study during menstruation. On some occasions, requested additional after ovulation. Histerosalpingografía.

This radiograph is performed by injecting a contrast solution into the uterine cavity vaginally. To minimize the inconvenience it may cause, it is desirable to prescribe a mild sedative or an antispasmodic a little earlier. Is to be made after completion of menstruation and before ovulation.

The ability to detect abnormalities of the uterine conformation, as well as drugs and the internal cervical os.

Ultrasonography
Today, it is almost de rigueur to supplement when detected abnormalities or were looking for, for example, to check ovulation. Prefers to be performed by transvaginal route by the largest amount of data it provides. It gives a picture of the uterine cavity, the uterine body and ovaries.

Many gynecologists use the routine in menopausal women, especially if you are obese, as a method of early detection of tumors oval.

Endometrial biopsy
It is performed in the study of the patient sterile. It is used to diagnose ovulation and the quality of the tissue to be implanted into the pregnancy. Is to extract, vaginally, a small sample of tissue from the uterine cavity using a cannula and striving with a syringe or a microcureta.

Cytology (wipers) endometrial
It is used to irregular bleeding (especially at menopause) for the diagnosis of possible tumors. It is done by placing a small vaginal swab inside the uterine cavity.

Laparoscopy
It requires general anesthesia and temporary placement. Place a sort of '' telescope of 50 centimeters and 0.5 centimeters in diameter, with a cold light source that is introduced by a tiny incision in the umbilical scar. Lets see inside the genitals (uterus, fallopian tubes and ovaries) and perform multiple operations on them without having to open the abdomen.

Which is the largest twin brother?

What is it? The first born? Does the first in shape?
Much has been said about that first birth is the lowest and the highest last. None of that is true. For the law, the first born, is undoubtedly the largest. Simple question of logic. In biology, everything is possible.

In the case of identical twins, generated from a single fertilized egg, both biologically-be-equal in age, and that his life began simultaneously.

If these are simple twins, the product of fertilization of two different eggs by two different sperm, there is-to-date any possibility of knowing if the fertilization was simultaneous or deferred.

And in the case of in vitro fertilization?
Even if, as in the case particularísimo of in vitro fertilization, we know exactly the time at which each egg was inseminated and the time at which each embryo was transferred to the interior of the uterus, we will never know which is which at the time of birth. That figure could only be made known whether a biopsy for genetic study of the embryo before transferring to the uterus, something-for now-is only possible in very limited. Most countries where technically feasible, the laws are very strict regarding the possibility of the so-called "pre-implantational biopsy of embryos.

Almost science fiction. Hence, not to discuss more: the first birth is the largest, but in reality was the ultimate gesture.

Biopsy of chorionic

The biopsy chorionic, allows the state of the fetus and conduct the so-called prenatal diagnosis of morphological alterations, or molecular functional. The procedures used for them are of two kinds: one using ultrasound (noninvasive), or the other by fetal samples (invasive).

The choice of diagnostic technique to use, and depend on several factors besides the objective analysis. For example, to identify a possible molecular alteration, can not be used ultrasounds, but some of the techniques of sampling fetal. Among them, we can make in the earliest period of gestation is the biopsy coriales villi.

The study consists of obtaining a sample of chorion villus, either cervical, or through the abdominal wall under control ultrasound. With the sample can be obtained chromosome studies, molecular and biochemical. The advantage is that it can be done at very early periods of pregnancy.

After sample extraction of coriales villi, can occur on an exceptional basis, a slight increase in complications, being contraindicated in some women with conditions anatomical and private clinics.

All these considerations imply that the type of technique prenatal diagnosis should be suggested by the gynaecologist according to the characteristics of each woman, with the objective diagnosis to try and achieve pregnancy at the time deemed most appropriate.
