Varicocele is a common condition characterized by prolongation, dilation and tortuosity of the trapezius plexus of the spermatic vein. It has attracted widespread attention from masculologists in the last decade or so. Dubin statistical analysis of 1,294 cases (1978) of male infertility, with varicocele accounting for 512 cases (39%), accounting for the first cause of male infertility. I. Clinical manifestations Varicocele is mostly seen in young men between 20 and 30 years old, and about 30% have symptoms. The scrotum is distended when the patient stands, with a feeling of heaviness and swelling, which can radiate to the lower abdomen and groin, and is aggravated when standing and walking, and reduced after lying down and resting. In severe cases, the superficial veins of scrotum and inner thighs are dilated and light blue trailing vascular plexus can be seen, and the varicose veins can be felt on palpation like earthworm clusters, which fill up when standing and disappear or shrink after lying down. Clinically, varicocele is classified into four grades: Grade 0: no varicocele symptoms and negative Valsava test. Grade I: but Valsava method examination is not obvious on palpation as positive. after Val Sava maneuvering Grade II: dilated veins are easily palpable on palpation, with a diameter of about 2 mm, but not easily visible. Palpable Grade III: dilated veins can be seen in standing position as worm-like masses protruding from the surface of the scrotum and are easily palpable. Visible Semen examination Semen characteristics of varicose spermatozoa: reduced number of sperm, reduced motility, increased immature sperm. Indications for varicocele surgery surgery 1.Infertile spermatozoa with abnormal semen examination should be operated promptly as soon as the diagnosis of varicocele is established. 2.Severe varicocele with obvious symptoms, such as more standing that the scrotal swelling and pain, physical examination found that the testicles are obviously shrinking, even if there is fertility, the patient has a desire for treatment can also be considered for surgery. 3, clinical observation found that the incidence of prostatitis, seminal vesiculitis in patients with varicocele is significantly increased, twice as much as normal people, so if the above two diseases exist at the same time, and prostatitis is not cured for a long time, you can choose to perform varicocele surgery. 4, for adolescent varicocele, because it often leads to pathological and progressive changes in the testicles, it is now advocated that adolescent varicocele with testicular volume reduction should be treated with surgery as early as possible, which can help prevent infertility in adulthood. 5.For patients with mild varicocele, if the semen analysis is normal, they should be followed up regularly (every 1-2 years), and once the semen analysis is abnormal, the testicles shrink and become soft in texture, they should be operated in time. 6. For patients with varicocele accompanied by oligospermia due to non-obstructive factors, it is recommended to perform testicular biopsy and varicocele surgery at the same time to help perform assisted reproduction. For the treatment of varicocele, our hospital currently chooses laparoscopic spermatic vein high ligation, which has the advantages of reliable results, less damage, fewer complications, simultaneous bilateral surgery, quick recovery, and short hospital stay compared to traditional open surgery, and has been well received by the majority of patients.
