There are several causes of varicocele, which might be due to damage or congenital deficiency of the valves in the spermatic veins. It may also be caused by prolonged standing or sitting, strenuous exercise, or venous reflux difficulties due to gravity. Some patients suffer from varicocele due to renal vein thrombosis caused by a tumor within the renal vein, or external tumors compressing the spermatic veins. Additionally, natural anatomical structures also play a significant role, particularly in left-sided varicoceles. This is because the left spermatic vein is longer, enters the left renal vein at a right angle, and is compressed by the superior mesenteric artery. These factors heighten venous backflow pressure, which over time can also lead to varicocele.

Varicocele is caused by what?

Common causes of varicocele include: 1. Abnormal venous valves: The venous valves in the spermatic vein help prevent the backflow of blood. If these valves are abnormal, it can lead to blood reflux, causing varicocele. 2. Higher incidence of varicocele on the left side: Varicoceles are more likely to occur on the left side because the left spermatic vein enters the left renal vein at a right angle. Moreover, the left renal vein is often compressed by the superior mesenteric artery and the abdominal aorta, leading to obstructed blood flow in the spermatic vein. 3. Other secondary pathological changes, such as retroperitoneal tumors, renal tumors compressing the veins in the spermatic cord, or tumor thrombus embolizing the renal vein, can also cause obstruction in the spermatic venous flow, leading to varicocele.

Can varicocele cause urethral stinging?

Varicocele generally does not cause a burning sensation in the urethra. The main symptoms of varicocele are a dragging pain in the testicles, especially after long periods of standing, sitting, or intense physical activity. The pain becomes more pronounced, and the affected testicle may noticeably sag when standing. A color Doppler ultrasound can confirm the diagnosis. The most common cause of urethral burning sensation is urethritis or the presence of stones in the urethra, which needs to be confirmed through routine urine tests. If an increase in white blood cells is observed during the urine test, it can be diagnosed as a urinary tract infection. This condition requires timely treatment with antibiotics, and typically, a course of seven to ten days can lead to recovery.

What are the harms of varicocele?

The common hazards of varicocele are as follows: 1. Patients with severe varicocele may experience discomfort and scrotal heaviness, especially after long periods of walking or standing, with more pronounced pain symptoms. Symptoms may alleviate when lying flat. If untreated, the pain will persist. 2. Varicocele may affect the blood return in the testicles, potentially raising testicular temperature, adversely affecting the survival and growth of sperm. This may result in abnormal semen quality, including anomalies in sperm count and quality, which in severe cases could lead to infertility.

Varicocele is caused by how?

Varicoceles can be seen in primary diseases, but they may also be secondary to other pathological changes. Generally, the anatomical characteristics of the venous walls within the spermatic cord make it easy for blood in the spermatic veins to have reflux problems, thereby leading to varicoceles. This is mainly because there are venous valves to prevent backflow when the veins inside the spermatic cord drain into the renal vein. If these valves are not fully developed, it can easily cause backflow, leading to varicoceles. Moreover, varicoceles occur more frequently on the left side than on the right. The left spermatic vein generally enters the left renal vein at a right angle, which also facilitates the occurrence of varicoceles. Secondary varicoceles may be caused by retroperitoneal tumors or renal tumors compressing the spermatic vein, thus leading to obstruction in spermatic vein reflux.
