What Are the Most Common Vasectomy Problems?

It is a direct continuation of the epididymal tube, about 50 cm long, with a thicker wall, a more muscular layer, and a small lumen. When it is touched by a living body, it is in the shape of a round cable and has a certain firmness. The vas deferens travels long, starting from the epididymal tail, and entering the seminiferous cord along the posterior margin of the testicle. In the seminiferous cord, it is located on the posteromedial side of other components. The position of this vase is superficial. Vasectomy is often performed here. It then enters the abdominal cavity through the inguinal canal and immediately bends inward and into the small pelvic cavity. At the beginning, go down the pelvic wall and back, and then pass the front of the ureter to the back of the bladder. Here, the vas deferens on both sides gradually approach and expand into the ampulla of the vas deferens. The lower end of the vas deferens ampulla converges with the excretory tube of the seminal vesicle glands to form an ejaculation tube. The ejaculation tube is about 2 cm long, penetrates the bottom of the prostate, and opens in the prostate of the urethra.

Vasectomy 1. Vasectomy:

Introduction to Vasectomy :

Vasectomy, also known as vasectomy (deferentectomy), is a permanent method of birth control in men. After surgically incision of the skin, the vas deferens were raised and separated, cut off slightly from the epididymis, and cut about 0.8 cm, and then the two stumps of the vas deferens were ligated respectively, so as to achieve the purpose of blocking the sperm output path and permanent contraception.

Complications after vasectomy :

Hematoma:

Hematoma is the most common recent complication after vasectomy. The scrotal tissue is loose, and blood vessel damage is more likely to cause hematoma. In general, superficial vascular injury can cause small hematomas or large hematomas; if the spermatic venous blood vessels or vas deferens arteries are injured, huge hematomas can be caused; if the testicular arteries are injured, because there is no collateral circulation, hematomas can also cause testicular atrophy Or necrosis.

2. Infection:

Infection is also a more common recent complication. Mostly due to inadequate sterilization before surgery or original inflammation of the genitourinary system and unclean sex after surgery.

3. Painful nodules and pain syndrome after vasectomy (PVPS):

Causes of painful nodule formation: (1) Improper surgical operation, severe damage to adjacent tissues, leading to scar formation or postoperative infection; (2) Foreign body sensation caused by too thick ligature; (3) Sperm cord ligation operation is too rough Incomplete separation of the tissue surrounding the vas deferens during sheath ligation, leading to excessive formation of indurated tissues or peripheral neuroma-like proliferative nodules. The pathological basis of painful nodules is mainly the chronic inflammatory infiltration of surrounding tissues caused by the leakage of sperm from the stump, that is, the formation of sperm granuloma. Painful nodules are more common after ligation, and the pain worsens during sexual excitement or ejaculation, which usually relieves itself. In recent years, there have been cases of hemangiomas secondary to painful nodules from ligation.

4. Epididymal stasis:

Epididymal stasis is a long-term complication after surgery. Because vasectomy blocked the output of semen, the original secretion-absorption balance of the epididymis was disrupted, and semen production did not stop, so it was inevitable that the semen would accumulate in the epididymis, causing epididymal swelling Thick, but not all semen will develop into epididymal stasis.
