Varicocele and male infertility: all about varicose veins of the testicle

Dilation of the veins of the spermatic cord is called varicocele.

The spermatic cord is a formation that includes the vas deferens (through which sperm are released into the urethra), an artery and veins. Through the veins of the spermatic cord, blood flows from the testicle into the main veins (inferior vena cava and renal). Most often, varicocele is observed on the left, less often on the right, and very rarely it is bilateral.

Many people know such a disease as varicose veins. The disease is based on poor functioning of the valves in the veins, which leads to reverse blood flow and dilation of the veins (blue dilated veins on the legs are visible to the naked eye). The same dilation of the veins, only surrounding the spermatic cord, also occurs with varicocele. Often diseases such as varicose veins, hemorrhoids and varicocele occur in one patient.

According to medical research, varicocele is observed in every seventh man. Using ultrasound examination, varicoceles were detected in 35% of men of reproductive age. Varicocele in children is quite rare; more often it is congenital. Varicocele in adolescents forms during puberty.

In 80% of cases, varicocele occurs on the left side, in 2-12% bilateral varicocele is detected, and in only 3-8% - right-sided varicocele. In a mild form, the disease does not manifest itself in any way and does not threaten the man’s life.

The danger of varicocele is that it can become (and in 80% of cases does) cause infertility. Another dangerous complication of the disease is testicular atrophy.

Varicocele causes

Varicocele does not cause pain, and only occasionally can be manifested by aching or pulling sensations in the testicle . This is the insidiousness of this disease, because it can be difficult to convince a patient who is not in pain to go under a knife (although today it is, of course, not a knife, but a microsurgical instrument ). But it is necessary to undergo surgery, because due to varicose veins of the spermatic cord, blood stagnation occurs in the testicle , its blood supply suffers and the local temperature rises. All these factors, acting gradually and imperceptibly, lead to disruption of the process of formation and maturation of sperm, and in advanced cases - to a decrease in the size and atrophy of the testicle . The sooner varicocele , the greater the chance of preventing negative consequences for the man’s body.

In patients with varicocele, pathological changes in the spermogram are often detected. The most common are oligozoospermia (a decrease in the concentration of sperm to less than 15 million per ml), asthenozoospermia (a decrease in the concentration of progressively motile sperm to 32% or less), teratozoospermia (a large number of pathological forms of sperm, exceeding 96%). Varicocele is characterized by damage and fragmentation of sperm DNA .

Several studies in recent years have confirmed the relationship between varicocele and decreased testosterone levels and erectile dysfunction .
Thus, in 2011, a group of Indian scientists led by Sathya Srini V. published the results of treatment of 200 patients with hypogonadism and erectile dysfunction in combination with varicocele. Some of these patients received hormone replacement therapy, while others underwent surgical treatment of varicocele. In 78% of patients who underwent surgery to eliminate varicocele, normalization of testosterone levels was achieved with improvement in erectile function. Similar results were demonstrated by the Polish urologist D. Paduch. In his study of infertile men with varicocele and hypogonadism, 76% achieved normalization of testosterone and improvement in sexual function after surgical treatment of varicocele.

Prevention

It is easier to prevent any disease than to treat it, so it is necessary to carry out preventive measures.

Measures aimed at reducing the risk of developing pathological dilation of veins in the scrotum:

• healthy eating has a beneficial effect on the intestines;
• taking vitamins;
• use contraception during sexual intercourse;
• reasonable physical activity;
• Regular visits to the doctor from adolescence.

Reasonable adherence to preventive measures not only minimizes the risk of developing the disease and its relapse, but also contributes to the choice of an effective and less invasive treatment method.

Degrees of varicocele

Varicocele grades (according to the criteria of the European Association of Urology):

The second and third stages may be accompanied by a decrease in size (hypotrophy) of the corresponding testicle.

Symptoms

The severity of varicicol symptoms is related to the degree of dilation of the veins. The initial stages have no signs of pathological development. Varicose veins can only be detected during a preventive examination.

Varitsikole 2 degrees are characterized by complaints of pain in the scrotum. At the same time, the severity of pain varies. Symptoms of varicicole at this stage:

• discomfort while walking;
• sharp almost neuralgic pain;
• burning in the scrotum area;
• sexual dysfunction;
• increased sweating;
• asymmetrical position of the testicles and sagging of half of the scrotum;
• visible dilatation of veins.

Grade 3 varicicole is characterized by a lack of connection between physical activity and the occurrence of pain. The pain syndrome becomes constant and intense. Externally, countless clusters of veins and the brightness of the asymmetrical appearance of the scrotum are noted.

TREATMENT OF VARICOCELE

Varicocele surgery

Varicocele in men treatment

As I already mentioned, conservative methods of treating varicocele are ineffective . A weak and stretched vein wall cannot be strengthened with medications. Therefore, the only effective treatment for varicocele is surgery. There are various options for operations for varicocele . Dilated veins can be ligated in the inguinal canal, above or below it. An endovascular approach is possible - embolization and sclerosis of dilated veins. However, the “gold standard” is microsurgical infrainguinal (subinguinal) ligation - the Marmara operation. Let's consider the features of each of these operations used to treat varicocele .

Diagnostics

An angiosurgeon or phlebologist can easily identify varicicole. Diagnosis determines the relationship between symptoms and treatment for varicicole. Primary diagnosis consists of collecting anamnesis - interviewing the patient about the nature and presence of complaints, their dependence on physical activity or injuries received.

At certain stages of the disease, physical examination reveals visible varicose nodes, and palpation gives an idea of ​​plexuses in the bunch. A sign of pathology is laxity of the affected testicle. Palpation must be carried out standing and lying down under pressure and in a calm state, which makes it possible to clarify the localization of the diagnosis.

Instrumental diagnostic methods:

• with varicicol, ultrasound is done for the abdominal cavity, including the kidneys;
• MRI and CT to exclude thrombosis;
• after adulthood, a spermogram is performed - pathology shows asthenozoospermia or oligospermia, a decrease in activity or quantity, respectively.

Additional diagnostic methods:

• Ultrasound of the scrotum,
• dopplerography,
• thermography and thermometry,
• rheography.

To construct a treatment regimen for varicicolitis in men, retrograde venography of the kidneys and testicles, transscrotal testicular phlebography and antegrade venography are performed.

The multidisciplinary medical clinic (academician Roitberg’s clinic) offers modern, accurate and fast research methods.

How to treat varicocele

Operation Palomo

In this operation, a 5-6 cm long incision is made in the lower lateral part of the abdomen, above the inguinal canal. In this place, the testicular vein is usually a single trunk, running along with the testicular artery and lymphatic vessels. The surgeon isolates, ligates and cuts the vascular bundle as a single block. General or spinal anesthesia is most often used. The disadvantage of the Palomo operation is the intersection of the testicular artery that supplies the corresponding testicle, which can worsen its functional state. The intersection of lymphatic vessels can lead to the formation of hydrocele (hydrocele). Recovery and rehabilitation after Palomo surgery takes about 2 weeks.

Operation Ivanissevich

The length of the incision is approximately the same as during the Palomo operation, but the incision itself is made lower, directly in the area of ​​the inguinal canal. The spermatic cord (containing dilated veins) lies quite superficially in this place, which makes it possible to isolate it. Typically, the operation is performed under general or spinal anesthesia, although local anesthesia is also possible.

During the Ivanissevich operation, the surgeon tries to preserve the testicular artery and lymphatic vessels, but the lack of optical magnification makes this task difficult. In case of ligation of the artery and lymphatic vessels, the complications described above may occur (testicular atrophy, hydrocele formation). The recovery period after Ivanissevich's surgery lasts about 2 weeks .

Operation Marmara

Marmara operation (subinguinal microsurgical ligation of the veins of the spermatic cord). This technique was first described by American urologist Joel Marmar in 1985. Through a small (about 2 cm) skin incision in the groin area (below the inguinal canal), the spermatic cord is isolated. Using optical magnification (operating microscope or binoculars) and microsurgical techniques, the elements of the spermatic cord (vas deferens, testicular artery, tributaries of the internal spermatic vein and lymphatic vessels) are separated. Venous vessels with a diameter of more than 2 mm are ligated (ligated) and divided. All other elements remain intact. The operation ends with the application of a cosmetic suture.

In 1992, another American urologist-andrologist Mark Goldstein modified the Marmara operation, proposing to cross not only the branches of the internal spermatic vein, but also the veins of the scrotum (branches of the external spermatic vein and gubernacular veins), for which it is necessary to remove the testicle into the surgical wound. The Goldstein modification is still actively used by urologists around the world, especially for recurrent forms of varicocele.

The Marmara operation can be performed under general or spinal or local anesthesia. The minimal incision length and microsurgical technique make it possible to perform this operation on an outpatient basis, without hospitalization.

In most cases, the patient can leave the clinic within 1-2 hours after surgery. Complications during the Marmara operation are much less common than with other types of operations used for varicocele. The functional and cosmetic results of Marmara surgery are also significantly better than other techniques. The number and motility of sperm increases to a greater extent. It is natural that the Marmara operation is currently considered as the “gold standard” for the surgical treatment of varicocele.

Scrotal access

Varicose testicular veins can also be divided at the level of the scrotum. Through a small incision of about 1-2 cm, the spermatic cord is isolated, followed by the intersection of varicose veins. The main stages of the operation correspond to the Marmara technique . The main difficulty with scrotal access is that the internal spermatic vein at the level of the scrotum is represented by a network of veins of different sizes, forming a pampiniform (or pampiniform) venous plexus. To achieve a good effect, it is necessary to cross each of these branches, which, of course, increases the operation time. The scrotal approach is currently rarely used for the treatment of varicocele.

Laparoscopic ligation of the testicular vein

Like any other laparoscopic surgery, ligation of the testicular vein is performed through punctures in the anterior abdominal wall. The operation is performed only under general anesthesia. Instruments and an optical system are introduced through punctures into the abdominal cavity. The testicular vein is isolated near the internal opening of the inguinal canal, metal clips are applied to it, and the vein is divided. The functional results of laparoscopic surgery for varicocele are generally close to the results of the Ivanissevich operation.

The postoperative period is easier than during the operations of Palomo and Ivanissevich , punctures in the abdomen heal quite quickly. Typically, the patient is discharged home the next day after laparoscopic ligation. The only advantage of laparoscopic surgery for varicocele, in my opinion, is the ability to cross the testicular veins on both sides (for bilateral varicocele) through the same access. The disadvantages of the laparoscopic approach are the need for general anesthesia, as well as the risk of complications associated with the introduction of instruments into the abdominal cavity.

Testicular vein embolization for varicocele

This technique is the least invasive among all those used to treat varicocele . The absence of an incision allows embolization to be performed under local anesthesia (or without anesthesia at all!). Naturally, there is no need for seams. A thin catheter with a flexible guide is inserted through a needle into the femoral vein. Contrast is injected through the catheter into the vasculature, and the location and movement of the guidewire and catheter are monitored using fluoroscopy. The catheter is passed retrogradely (from the renal vein towards the testicle) into the internal spermatic (testicular) vein. The structure and features of the testicular vein are assessed, and possible additional branches and tributaries are identified. After this, a coiled spiral is inserted through the catheter into the lumen of the vein. In the lumen of the vein, the spiral expands, firmly pressing against the walls of the vein and fixing itself inside. Then an embolic substance is injected into the lumen of the vein, completely closing the lumen of the vein. A control study of blood flow through the vein is performed. If there is no blood flow, the operation is completed.

The patient can leave the clinic within two hours after the operation . Recurrence of varicocele after embolization is very rare. Another advantage of embolization for varicocele is that during the procedure, fluoroscopy of the veins is performed, which makes it possible to diagnose various anatomical anomalies, additional branches connecting the testicular vein with the vein of the same name on the opposite side, and other vascular features leading to relapses of varicocele. In this regard, embolization may be particularly effective in cases of recurrent varicocele. Like any method, testicular vein embolization is not without its drawbacks.

One of the significant ones is the need to administer a contrast agent (usually the same as is administered during computed tomography). Some people have an allergic reaction to contrast and cannot undergo embolization. In addition, the administration of contrast is contraindicated in renal failure. Therefore, before this operation, the blood creatinine level must be checked.

Another limitation for embolization is right-sided varicocele. Right-sided localization is uncommon with varicocele. But, due to anatomical features, inserting a catheter and guide into the right testicular vein is often very difficult. Therefore, for right-sided (or bilateral) varicocele, it is better to resort to surgical treatment methods rather than embolization.

The high cost and relatively low availability of embolization are also of particular importance. The cost of embolization for varicocele, as a rule, is several times higher than the cost of surgical treatment (including the Marmara operation). This is due to the use of expensive disposable consumables and the need to work in an endovascular operating room equipped with high-resolution fluoroscopic equipment (angiograph). Embolization is a highly operator-dependent technique, the effectiveness and safety of which largely depends on the surgeon (human factors).

Complications from testicular vein embolization are rare . These include an allergic reaction to contrast, impaired renal function, bleeding from the puncture site, and perforation of the vein wall. A rare specific complication is migration (displacement) of the installed coil and its movement along the vascular bed with the occurrence of embolism in various organs.

Comparison of different operations for the treatment of varicocele :

, in accordance with the recommendations of the European Association of Urology , I perform on my patients the most modern operation for varicocele - microsurgical subinguinal ligation of varicose veins according to Marmar, and I have extensive experience in this operation.

Treatment of varicocele without surgery

Many of my patients, who are faced with such a problem as varicocele for the first time, are primarily interested in whether it is possible to treat varicocele without surgery. Of course, it would be very tempting to do without surgery, or even better to cure varicocele with folk remedies. Unfortunately, I have to disappoint them. There are currently no effective methods for treating varicocele without surgery. A temporary positive effect can be provided by some herbal remedies that increase the tone of the veins (horse chestnut tincture, grape leaves), as well as medications (for example, Aescusan, Detralex, Phlebodia, etc.). Varicoceles, of course, will not go away with these medications, but the symptoms may decrease. To reduce the symptoms of varicocele, adherents of traditional medicine recommend limiting physical activity and wearing tight-fitting underwear (so that the scrotum does not sag, but is pressed against the perineum). Temporary relief can be expected from these measures, but the varicocele itself will not disappear. Therefore, I must state that attempts to cure varicocele without surgery only waste precious time.

Treatment of varicocele - operations

As I already mentioned, conservative methods of treating varicocele are ineffective.

Statistics on varicocele: why you need to see a urologist during puberty

The content of the article

Typically, pathology develops in young men during puberty. It is during this period that the disease reaches its peak, which, with timely detection and treatment, can be prevented.

Statistics show how high the risk of remaining infertile is for any young man who does not attend routine examinations with a urologist. According to her data, every fifth man over the age of 17 suffers from varicocele. In a third of cases, the pathology reduces the ability to conceive (fertility).

Advantages of Marmara microsurgery:

1. A small cosmetic incision in the groin area, in the hair growth area (the scar is almost invisible)
2. The greatest efficiency of the operation is achieved through the use of operating binoculars and microsurgical instruments
3. Lowest percentage of relapses and complications (less than 5 percent)
4. Can be performed on an outpatient basis, without hospitalization
5. Short and easy postoperative and recovery period

I am aware of my responsibility for preserving the main thing that my patient trusts me, and I will do everything to justify the trust!

Stages of development of testicular varicose veins

Varicocele begins with a mild form and gradually progresses. At the same time, the pathology does not always reach its climax; varicose veins can stop developing, remaining undetected.

The disease occurs in 4 stages:

• Symptoms of varicocele are hidden.
  The veins of the testicle are not visible or palpable. Dilatation of the veins is detected on ultrasound of the scrotum. That is why preventive ultrasound examination is recommended for all young men at the age of 17-18 years.
• The veins are palpated in a horizontal position.
  In the supine position no changes are noticeable.
• Veins can be palpated in any position.
• Dilated veins are greatly enlarged and visible
  . If severely disturbed, they may even hang down. Pain appears.

Spermagenesis is disrupted gradually, which leads to infertility. The brighter the signs, the more reasons to suspect a male factor in infertility.
