Enlarged seminal vesicles

Introduction The seminal vesicle is not an organ that stores semen, but an accessory gland of the male genitalia. It is a pair of oblong-shaped cystic organs. Located at the back of the bladder bottom, the outside of the ampulla of the vas deferens. The shape is wide and narrow, the front and back are slightly flat, the surface is uneven, the upper end is free, the larger the swelling is the bottom of the seminal vesicle, and the lower end is straight and straight, which is the drainage tube. Because of the structural characteristics of the seminal vesicles, after the inflammation occurs, the drainage is not smooth, and the bacteria are often left behind after the invasion of the bacteria, and it is difficult to completely cure. In order to prevent the prosperous period from prolonged, whether it is acute or chronic seminal vesiculitis, it should be completely treated. The seminal vesicle, also known as the seminal vesicle, is the accessory gland of the male genitalia. The seminal vesicle produces mucus, which provides carriers and nutrients for sperm, which facilitates the transportation and storage of sperm. The enlargement of the seminal vesicle is generally more common in seminal vesicle. Seminal vesiculitis is a disease caused by Escherichia coli or the like causing infection in the adjacent organs such as the prostate or in any case causing the prostate and the seminal vesicle to be congested, and the bacteria invade the seminal vesicle and induce inflammation, thereby causing blood essence as the main clinical manifestation. Seminal vesiculitis is divided into two categories: non-specific and specific seminal vesiculitis. The former includes acute seminal vesiculitis and chronic seminal vesiculitis, the latter including seminal vesicle tuberculosis and gonococcal seminal vesiculitis. Among them, non-specific chronic seminal vesiculitis is the most common.

Cause

(1) Causes of the disease

There are several ways to infect the seminal vesicles:

1 retrograde infection through the urethra, the most common;

2 spread of prostate infection;

3 infected by vas deferens;

4 by blood and lymphatic infection. The pathogens include Staphylococcus aureus, Streptococcus, Escherichia coli, and Corynebacterium diphtheriae; and can also be caused by Trichomonas, Mycobacterium tuberculosis, and Neisseria gonorrhoeae.

(two) pathogenesis

Due to the particularity of the anatomical location of the seminal vesicles, most scholars believe that seminal vesiculitis is closely related to prostatitis, often occurring simultaneously or simultaneously, and is associated with inflammation of other organs of the genitourinary system. Due to the characteristics of the tissue structure, the seminal vesicles have many discs and mucosal folds, which are easy to drain, and the bacteria are not easily eliminated. Fructose is a good medium for bacteria, so acute seminal vesiculitis is not completely treated and can be prolonged. Chronic seminal vesiculitis; can also be caused by frequent excitement or masturbation, causing chronic congestion and edema of the prostate and seminal vesicle, secondary infection causing chronic seminal vesiculitis.

According to the typical clinical manifestations, the possibility of seminal vesiculitis should be considered and it needs to be differentiated from prostatitis. Semen examination is important for diagnosis and can be diagnosed as bacterial seminal vesiculitis in combination with imaging examination.

Acute seminal vesiculitis

(1) People who have been infected with blood may have chills, fever, body aches and symptoms of lower abdominal pain. Transurethral retrograde infection has frequent urination, urgency, dysuria, perineum and rectal pain.

(2) The rectal examination can reach the enlargement of the seminal vesicle, and the tenderness is obvious. The abscess formation may have a sense of fluctuation.

2. Chronic seminal vesicle

(1) Blood sperm: This is often a feature of chronic seminal vesiculitis. The appearance of semen is pink, dark red or brown, and a few are accompanied by old crumb-like blood clots. Blood is often difficult to stop, and it will last for several months. Most patients have no ejaculation pain.

(2) Sexual dysfunction: Many people are afraid of blood and avoid sexual intercourse. Those with longer time often have decreased libido, frequent spermatorrhea and premature ejaculation.

(3) urinary tract symptoms: Most patients have no obvious urinary tract irritation, more complaints of perineal and lower abdominal discomfort, some patients have urinary tract burning sensation, primary hematuria after ejaculation.

(4) Neurological symptoms: Because of fear of the influence of blood essence on the health of themselves and their spouses, they are worried about affecting fertility, so the burden of thought is heavier. Patients often feel dizzy and weak, and the course of the disease is particularly obvious.

(5) digital rectal examination: the obese people often palpation of the seminal vesicles, some patients can have a slightly harder texture of the seminal vesicles, increase and tenderness, the boundaries of the seminal vesicles are unclear around the adhesion.

Differential diagnosis

According to the typical clinical manifestations, the possibility of seminal vesiculitis should be considered and it needs to be differentiated from prostatitis. Semen examination is important for diagnosis and can be diagnosed as bacterial seminal vesiculitis in combination with imaging examination.

Differential diagnosis of seminal vesicle enlargement:

1, seminal vesicle tuberculosis: mainly manifested as urination discomfort, lower abdomen, perineal pain and blood. However, in the case of rectal examination, patients with seminal vesicle tuberculosis may have invasive induration in the prostate and seminal vesicles, and more often with epididymal nodules. Mycobacterium tuberculosis can be found in the smear or culture of prostatic vesicle fluid or semen M. tuberculosis, and the PCR polymerase chain reaction tuberculosis test is positive.

2, spermatic cord thickening and swelling: spermatic cord thickening swelling is one of the symptoms of spermatic inflammation.

3, scrotal enlargement: scrotal enlargement refers to the scrotal skin and its contents (sheath, testis, epididymis and spermatic cord) have lesions, or abdominal contents (ascites, internal organs), etc. fall into the human scrotum, resulting in scrotal volume Increase. The scrotum wall or sheath, testis, epididymis and spermatic cord and other scrotum contents, due to acute and chronic inflammation, parasitic invasion, its own organic changes, tumors, etc. can cause pathological swelling of the scrotum, or inflammatory exudation Increase, edema and effusion. If the peritoneal sheath is not closed or not fully closed after birth, the contents of the abdominal cavity can be scrotum. Clinically, medical history and local palpation, light transmission tests and other physical examinations can determine the location and nature of the scrotal enlargement and make a correct diagnosis.
