Vesicoscopy can enter the seminal vesicles through the ejaculatory duct, retrograde inspection of the seminal vesicles and ejaculatory ducts through the normal anatomical pathway, and discovery of lesions can be dealt with at the same time under the luminal microscope. If it is tumor, it can be removed; if it is stone, it can be examined and removed under vesicoscopy; inflammatory changes can be treated by thermal cauterization or medication rinsing of the inflamed mucosa under microscope, which has the characteristics of convenient operation, direct observation and certain effect, and has become a new technology for diagnosis and treatment of hematospermia and oligospermia. Advantages of vesicoscopic surgery In the past, open surgery was usually performed for patients with seminal vesicle stones accompanied by hematospermia, and the location of seminal vesicles was very deep, traumatic, and bleeding, but now vesicoscopic surgery is performed by using the natural anatomical ducts, so it is less traumatic, with good effect, fast recovery, and very few complications, and it is a kind of minimally invasive technology that is worthy of promotion. Indications for vesicoscopy (a) hematospermia to be investigated: persistent or recurrent episodes of hematospermia for more than 3 months, after more than 4 weeks of antibiotics and standardized drug treatment is not effective; (b) male infertility: significant reduction in the volume of semen, watery semen with azoospermia, oligozoospermia, spermatospermia and other seminal anomalies, the suspicion of ejaculatory ducts with the presence of obstruction; (c) intractable pain in the perineum: pain in the ejaculation; pain in the testicles; lumbosacral (c) Perineal intractable pain: ejaculatory pain; testicular pain; lumbosacral, lumbosacral, and perineal distension, discomfort, and those who are ineffective in conservative treatment; (d) those who are highly suspected of ejaculatory vesicovaginal cysts, stones, and tumors. Contraindications to vesicoscopy (a) acute inflammation of the genitourinary system, such as acute cystitis, urethritis, prostatitis, seminal vesiculitis, etc.; (b) initial hematospermia or seminal vesiculitis, without regular conservative treatment; (c) recent use of anticoagulant medications, serious bleeding tendency or systemic bleeding disorders, such as leukemia, hemophilia, etc.; (d) serious cardiac, pulmonary, hepatic, renal, cerebrovascular diseases, malignant hypertension, poorly controlled, unable to withstand the test. (d) Serious heart, lung, liver, kidney, cerebrovascular system diseases, malignant hypertension, poorly controlled people who can not tolerate the surgery; (e) Serious prepuce, urethral stenosis and other diseases that make it impossible to place the vesicoscopy, according to the situation can be dealt with the prepuce, urethral stenosis, and then carry out the vesicoscopy and treatment.
