The tube connecting the testicles becomes thick and painful

Varicose veins are a disease that occurs in men, especially young men who are more susceptible to the disease. If we cannot take certain effective measures to treat it in time, it will cause a lot of harm. This disease is also an important cause of infertility in many men. The tube connecting the male testicles becomes wide and painful, which may be a symptom of varicose veins.

Varicocele is a vascular disease, which refers to the abnormal expansion, stretching and twisting of the pampiniform venous plexus in the spermatic flexure, which can cause pain and discomfort and idiopathic male testicular hypofunction. It is one of the common causes of male infertility. It has attracted much attention due to its related testicular pain and discomfort, infertility and testicular atrophy. It is a common male urinary tract disease. It is common in young people, with a prevalence rate of 10% to 15% in the normal male population, and 19% to 41% in male infertility.

Varicocele is a vascular obstruction of spermatogenesis caused by the enlargement of the spermatic veins and pampiniform plexus surrounding the spermatic flexure. It is generally common on the left side, accounting for about 77% to 92%. It can also occur bilaterally, accounting for about 7% to 22%. It is rare to switch to the right side, accounting for about 1%. Traditional surgical treatment uses a groin incision, high ligation of the internal spermatic vein, and removal of part of the enlarged vein in the vagina.

The incidence rate of sperm varicose veins in the general male population is 10% to 15%, accounting for 30% to 40% of primary male infertility, and 69% to 81% of secondary infertility. The chance of comorbidities among first-degree relatives of patients with varicocele is significantly increased: 21.1% of fathers and 36.2% of brothers may both have varicocele.

Varicose veins can be divided into adult type and adolescent type according to age. According to the cause of the disease, it can be divided into primary and secondary.

1. Primary VC

The left spermatic varicose vein is more common than the right one. The reason may be: the pressure in the blood vessel is increased, because the left spermatic vein has a long course and merges into the left renal vein at an oblique angle.； Blood "Nutcracker Condition" (NCS), the superior mesenteric aorta and pulmonary artery are compressed by the left renal vein, affecting the return of the left internal spermatic vein and even causing reflux, that is, "Nutcracker Condition" (NCS) ； The lack of connective tissue around the internal spermatic vein and venous heart valve defects are more common on the left side.

Relevant factors for the occurrence of primary spermatic varices: blood pressure, defective or poor function of the spermatic variceal valve, causing blood reflux； It is caused by human anatomy factors such as the thick wall of the spermatic vein and lack of surrounding connective tissue, or the underdevelopment of the cremaster muscle. Supplementary standing posture affects seminal venous return.

2. Secondary VC

The causes and symptoms include: left renal vein or vena cava tumor thrombus obstruction, renal tumors, intra-abdominal or retroperitoneal tumors, left renal vein or vena cava tumor thrombus obstruction, renal tumors, pelvic tumors, massive hydronephrosis, disordered blood vessels that are compressed and rise in the seminal flexure vein, etc.
