The uterine tubes, likewise known as oviducts or fallopian tubes, are the female frameworks that move the ova native the ovary come the uterus each month. In the existence of sperm and also fertilization, the uterine tubes deliver the fertilized egg to the uterus for implantation.

Gross anatomy

The uterine tubes room uterine appendages located bilaterally in ~ the superior section of the uterine cavity. This tubes departure the uterus with an area described as the cornua, forming a connection between the endometrial and also peritoneal cavities. Each uterine pipe is around 10 centimeter in length and also 1 centimeter in diameter and also is located within the mesosalpinx. The mesosalpinx is a wrinkles in the vast ligament. The distal section of the uterine pipe ends in an orientation encircling the ovary. The primary role of the uterine tube is to deliver sperm toward the egg, i beg your pardon is released by the ovary, and to then permit passage of the fertilized egg ago to the uterus because that implantation. <1>


A uterine tube consists of 3 parts. The an initial segment, closest to the uterus, is dubbed the isthmus. The 2nd segment is the ampulla, which becomes an ext dilated in diameter and is the most common site because that fertilization. The final segment, located farthest indigenous the uterus, is the infundibulum. The infundibulum gives rise come the fimbriae, fingerlike projections that space responsible for picking increase the egg released by the ovary.


The arterial it is provided to the uterine tube is indigenous branches the the uterine and also ovarian arteries; these small vessels are situated within the mesosalpinx.

The nerve it is provided to the uterine pipe is via both sympathetic and parasympathetic fibers. Sensory fibers run from thoracic segments 11-12 (T11-T12) and lumbar segment 1 (L1).


Microscopic anatomy

Histologically, the uterine tubes are composed that 3 layers—the mucosa, muscularis, and also serosa. The 3 various cell varieties within the mucosa that the uterine tubes include the columnar ciliated epithelial cell (25%), secretory cell (60%), and also narrow peg cell ( <5>




Females through salpingitis or tubo-ovarian abscess usually current with fever and also acute start of abdominal muscle pain. The uterine pipe in a patient with tubo-ovarian abscess generally has pus in ~ its wall surfaces (pyosalpinx). The diagnosis is made v ultrasonography, activities studies, and culture of the cervix or operation specimen, if applicable.


Salpingitis and also tubo-ovarian abscess space treated through intravenous antibiotics to cover common organisms that may have actually caused the ascending infection. Treatment is began before society results room finalized. The goal of therapy is to solve the symptoms and to maintain tubal function. (See additionally Pelvic Inflammatory condition Empiric Therapy and also Pelvic Inflammatory an illness Organism-Specific Therapy.) surgical procedure to remove the uterine pipe is warranted in part cases, depending upon the severity of infection.


Sequelae of this infections encompass infertility, chronic pain, and increased danger for ectopic pregnancy.


Hydrosalpinx

Hydrosalpinx occurs as an finish stage that pyosalpinx, a disorder defined by pus within the uterine tube. <6> Hydrosalpinx is the arsenal of sterile liquid within the tube an additional to occlusion that the tube (see above).


Ectopic pregnancy

Ectopic pregnancy is caused by a fertilized ovum implanting either in ~ the uterine tube or anywhere other than the endometrial cavity. In the circumstance of a tubal ectopic pregnancy, the lamina propria reacts like the endometrium and forms many decidual cells. <6, 7>


Because the lumen that the uterine pipe is small, it can not contain a cultivation pregnancy. As soon as the embryo or fetus becomes huge enough, it can rupture v the wall of the uterine tube, ending up being a clinical emergency. Prompt surgical intervention is required in this situation. If only among the uterine pipe is removed, it is still possible for pregnancy to take place on the opposite side.


If the ectopic pregnancy is detect on ultrasonography prior to it becomes too advanced, clinical treatment with methotrexate may be offered in some cases.
