Seminal vesicle stones

Introduction to seminal vesicles Seminal vesicle stones are very rare, and no more than 100 cases have been reported so far. Urine reflux, terminal menstrual malformations, ejaculatory duct obstruction and chronic infection may be the cause of the formation of seminal vesicles and ejaculatory duct stones. basic knowledge The proportion of illness: 0.004% Susceptible people: male Mode of infection: non-infectious Complications: male infertility

Cause of seminal calculi

(1) Causes of the disease

Corriere reported that the composition of the seminal vesicles is very similar to that of pancreatic stones. The formation of pancreatic stones is related to the abnormal expression of secreted pancreatic stone protein. Therefore, the reason for the formation of seminal vesicles is due to the lack of protease in semen.

(two) pathogenesis

Seminal vesicle stones are often accompanied by chronic inflammatory changes and fibrosis. The seminal vesicles can be completely obstructed. The seminal vesicle stones can be single or multiple. The core is epithelial cells and mucinous substances. The external sedimentary salts are 1 to 2 mm in diameter and some have 1 cm stones. The surface is hard.

Seminal calculus prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Seminal calculi complications Complications, male infertility

Abnormal obstruction caused by seminal vesicles caused severe infertility.

Symptoms of seminal calculi common symptoms frequent urinary exudation urgency epididymis stone essence

Seminal vesicles are asymptomatic, may have sexual dysfunction, and may have perineal and anal pain, ejaculation pain, blood and urination discomfort, urgency, frequent urination, clinical manifestations of inflammation combined with seminal vesiculitis.

Examination of seminal calculi

X-ray examination of the seminal vesicle area has a speckled shadow, and the high echo in the seminal vesicle can be found through the rectal B ultrasound.

Diagnosis and identification of seminal calculi

The diagnosis of this disease is mainly through the smooth induration of the rectum and the seminal vesicle, which is fixed and tender, and the multiple stones have a squeaking sound.
