Microscopic spermatic vein ligation usually requires a hospital stay of 5 to 7 days. The exact length of hospitalization is related to the patient’s condition as well as postoperative recovery. Varicocele is a common disease in men, most commonly seen in young adults, with the left side being the most common. Severe symptoms may be manifested as distension of the scrotum on the affected side, crushing, hidden pain, and so on. It may affect sperm production and semen quality, causing male infertility. Microscopic spermatic vein ligation surgery is an effective treatment for varicocele, which is less invasive and characterized by good efficacy and quick recovery. The general hospitalization time for patients is 5~7 days, but there are individual differences in recovery, which should be performed according to the doctor’s instructions. It is recommended to avoid heavy labor for 1 month after the surgery, quit smoking, limit alcohol, do not eat spicy and stimulating food, appropriate exercise, maintain a good mood, regular work and rest. If there are any abnormalities such as local swelling, pain, discomfort, skin color change, etc., please go to the hospital immediately.
