Chronic vesiculitis is a common disease in urology, mostly caused by prostatitis, prostate abscess, acute vesiculitis and vesicoureteral abscess, which is poorly treated conventionally. The hematospermia, ejaculatory duct obstructive azoospermia, ejaculatory pain, and seminal vesicle stones caused by seminal vesiculitis are common urological diseases. With the advancement of detection technology, the diagnosis rate of this disease has improved significantly. In the past, treatment for these patients mostly used sensitive antibiotics, but with the application of transurethral vesiculoscopy technology, the diagnosis and treatment of these diseases have made new progress. Vesiculoscopic technology is also one of the leading-edge technologies in minimally invasive urology in China at present. Ureteroscopy is used as a seminal vesicle mirror, through the urethra through the opening of the ejaculatory duct into the seminal vesicle, following the normal anatomical pathway of the seminal tract retrograde sequential examination of the ejaculatory duct and seminal vesicle, the discovery of lesions can be dealt with under the lumpectoscope at the same time, such as the discovery of tumors, can be removed; such as stones, can be removed under the seminal vesicle mirror, if necessary, can be lithotripsy and then flushed out or removed; inflammatory changes can be given under the mirror on the inflammatory mucosa electrocautery, the accumulation of blood for The treatment of inflammatory changes can be done by electrocautery of the inflamed mucosa under the microscope and flushing of the accumulated blood. Hemospermia is a common disease in urology. In the past, most cases were difficult to identify the cause and were considered “idiopathic hemospermia”. With modern imaging technology, the etiology of many cases of hematospermia can be clarified. In clinical practice, there is still a significant proportion of hematospermia cases with unknown causes. In some cases, even if the diagnosis is clear, the treatment often lacks effective treatment means, which becomes a therapeutic problem, and persistent and recurrent hematospermia still seriously affects the physical and mental health of patients. This technique can significantly improve the symptoms, with direct treatment, low chance of recurrence and minimal side injuries. The average operation time is short about 30 to 45 minutes, and the average hospital stay is 6 to 10 d.
