Patient's question:
A 3cm seminal vesicle cyst with no other symptoms, there is a slight swelling in the perineum, and seminal fluid leaks out when defecating. The harder the stool, the more seminal fluid leaks.Doctor's answer:
Analysis of the condition: A seminal vesicle cyst is a benign, cystic mass that grows within a specific organ of the body, with liquid-like contents. Seminal fluid constitutes 50%-80% of the main components of semen, while prostatic fluid accounts for 15%-30%. Additionally, there are small amounts of epididymal fluid, sperm, bulbourethral gland fluid, and paraurethral gland fluid. Therefore, when bleeding occurs in any part of the seminal vesicle, seminal vesicle cyst, ejaculatory duct, or posterior urethra, the semen appears brownish or dark brown. Posterior urethral bleeding is usually fresh blood, and the semen appears red or pink. The presence of blood in semen can be intermittent or persistent for months or even years.Advice: Symptomatic seminal vesicle cysts often require surgical treatment. Traditional treatment methods include transrectal cyst aspiration, transurethral resection of the cyst cap, and seminal vesicle resection. Transrectal cyst aspiration is only used for diagnosing and treating recurrent cysts due to its high recurrence rate and risk of infection. Transurethral resection of the cyst cap is rarely used because it is prone to complications such as urinary reflux, postoperative dripping, and infection. Laparoscopic cyst excision of the seminal vesicle provides excellent exposure to the deep pelvic region of the seminal vesicle, making the dissection and removal relatively simple, safe, and minimally invasive. By following the vas deferens, it is easier to locate the ampulla of the vas deferens and the cyst, thereby avoiding damage to nearby organs, especially reducing the risk of injuring the ureter and rectum. Postoperative recovery is rapid.
