Pelvis Simple Flat

The simple flat pelvis (p. simplex plana) is a type of pelvis that is found in some species of birds and mammals. This basin has a simple shape and a flat top edge, which distinguishes it from other types of basins.

A simple flat pelvis is important for the normal development of the fetus in the womb. It provides sufficient space for the growth and development of the fetus, and also protects it from external influences.

In birds, a simple flat pelvis is found mainly in species living in high mountain environments. In mammals, this type of pelvis is most often found in large animals such as elephants, rhinoceroses and hippopotamuses.

Although the simple flat pelvis is a common type of pelvis, it is not universal for all animal species. Some species of birds and mammals have more complex pelvises that provide more efficient use of uterine space and protection for the fetus.

The pelvis is simply flat - it is a cavity formation at the bottom of the uterine cavity, which is often caused by a tumor process in the rectosigmoid region or rectum. Typically, this condition does not cause any symptoms and is discovered incidentally during an ultrasound examination (ultrasound). Detection of a simple flat pelvis is a sign of intestinal disease, and in most cases, it is followed by a comprehensive examination of the patient.

Tumor neoplasms in the form of simple flat pelvises can be adenocarcinomas or carcinoids. In most patients with this disease, diagnosis and surgical treatment can be performed using endoscopic techniques. Thus, when the sigmoid colon or descending colon is affected, preference is given to colonoscopy or fibrocolonoscopy, and for the rectum and rectosigmoid colon, preference is given to either fibrography or cystoscopy.

The type of formation of a “simple” flat pelvis may differ in the size, shape and appearance of the tumor bodies. It is known that the formation is one and a half to two centimeters in size, has rounded outlines and has a yellow-brown color. As the tumor grows, its shape may become hairy or dome-shaped. In addition, the size of such a neoplasm can fluctuate within a fairly wide range due to the presence of fiber, chitinous membranes, muscles and remnants of the uterine lining in the tumor structure. Also, some researchers indicate that the walls of such a tumor may resemble dense clay or stone, and also have irregularly shaped areas. When such a tumor begins to show symptoms, including abdominal pain, frequent urge to defecate, fever and fatigue, then more accurate information about the size and shape of the tumor will no longer help the surgeon and urologist. These symptoms often cause the patient to seek urgent consultation with a specialist in surgery or urology.

It is also worth noting that simple flat pelvises are divided into three degrees of the disease: * 1st degree (a);

* 2nd degree (c);

3rd degree (c).

Rectal lesions are the least common. The most common development is:

inflammatory diseases of the large intestine;

neoplasms of a malignant or benign nature in places of ulcers and fistulas (at the junction of the rectum and
