microscopic varicocelectomy under local anesthesia as the treatment of varicocele

With the advancement of modern society, male infertility has gradually emerged as a global health issue, with varicocele being one of the predominant causes. The prevalence of varicocele is estimated at 15% in the general healthy population, 35% in those with primary infertility, and can be as high as 80% in the secondary infertility group1. Not only does varicocele lead to a decline in sperm count and quality2, but it also profoundly impacts the psychological well-being and quality of life of affected men.
Contemporary treatment modalities, such as microscopic varicocelectomy, have been widely adopted3,4. However, their limitations are becoming increasingly evident. Traditional microscopic varicocelectomy requires patients to undergo general anesthesia, which not only necessitates preoperative fasting and postoperative recovery inconveniences but also poses a significant challenge. The hemodynamic changes induced by anesthesia might obscure the pulsations of the spermatic artery, subsequently increasing the intricacy of isolating and preserving the vessel during the procedure5.
In light of these challenges, a method of performing microscopic varicocelectomy under local anesthesia was proposed and implemented. The salient advantage of this unique approach lies in its ability to swiftly and accurately pinpoint the pulsating spermatic artery, thus reducing the risk of injury to the vessel. Furthermore, local anesthesia offers a more patient-centric surgical experience, sidestepping the adverse effects of general anesthesia, and potentially reducing medical costs, presenting a more cost-effective and efficient treatment option. Additionally, considering the practical realities and clinical experiences in China, this innovative method proffers a fresh perspective in the treatment of varicocele and holds promise for broader clinical application. Through this research, a safer and more effective treatment alternative for patients would be provided, aiming to enhance their reproductive capabilities and overall quality of life.

Mikroskopisk åderbråckselektomi under lokalbedövning som behandling av varicocele

Varicocele is linked to 35%to 40%of male infertility cases during reproductive years. The globally accepted approach for treating this condition is through a microscopic varicocelectomy conducted under general anesthesia. This protocol demonstrates this surgery using local anesthesia to improve patient comfort and reduce financial costs.This new one should significantly shorten the required surgery time and offers opportunities for patients who cannot undergo general anesthesia. Under local anesthesia, we can more clearly observe the positions of symptomatic arteriole, which helps us make more a precise resolution and protection. We will focus on the changes in the small non-encoding RNAs after the surgery, because many patients seem to improve after surgery but still cannot conceive naturally.Based on our preliminary research, we speculate that small non-encoding RNAs may play an important role in this process.

Microscopic Varicocelectomy under Local Anesthesia as the Treatment of Varicocele

Varicocele, characterized by the dilation of veins within the spermatic cord, is a prevalent disease in males, accounting for 35%-40% of infertility cases among men of reproductive age. This condition may disrupt normal neuroregulation, blood supply, and temperature regulation in the testicles, thereby impacting sperm count, quality (morphology, fragmentation rate), and functionality (motility). It may even induce symptoms such as pain and testicular atrophy. The international standard treatment method is microscopic varicocelectomy, typically performed under general anesthesia. This requires patients to fast before surgery and necessitates recovery and fasting care postoperatively. The arterial blood pressure drop caused by anesthesia may obscure the fluctuation of the spermatic artery, making the precise intraoperative isolation and protection of the spermatic artery more challenging. Therefore, this study proposes and implements microscopic varicocelectomy under local anesthesia. This method facilitates rapid and precise identification of the fluctuating spermatic artery, reducing the risk of spermatic artery damage. It also provides more humane care for patients, reduces economic burden, and offers a new perspective on the treatment of varicocele.

Varicocele accounts for 35%-40% of infertility cases among men of reproductive age.

Surgical Intervention Under Microscope for Treatment of Varicocele

To begin, place the patient in a supine position on the operating table. Insert a vein detained needle into the radial vein, and use an electrocardiogram monitor, to track the patient's heartbeat and blood pressure. Then use fingers to palpate the spermatic cord at the base of the scrotum, following it upwards until the external inguinal ring is felt at 1.5 centimeters above the midpoint of the inguinal ligament.After injecting local anesthesia, use hemostatic forceps to grasp the skin to assess the efficacy of anesthesia, and mark the incision site with methylene blue. Using a scalpel, make a three centimeter transverse or longitudinal incision at the external inguinal ring. Sequentially, incise the skin, the Campers fascia, and the Scarpas fascia, using an electrotome.Identify the spermatic cord, which under direct vision appears as a strip with dilated deep blue veins and the vas deferens palpable below it. Exteriorize the spermatic cord from the incision with an appendiceal retractor. Use an electrotome to dissect the cremaster muscle, and the external and internal, spermatic fascia of the cord.Under 8 to 10 x magnification, observe the pulsation of the arteries to determine their location. Carefully identify the spermatic artery, which is surrounded by small veins, has visible pulsation, and a tensed wall. Use micro scissors and forceps for blunt dissection and mark the artery with a moistened strip for identification.Identify and isolate the large spermatic veins. Use micro titanium clips to clamp both ends of the vein before cutting. Further, dissect and identify small veins adjacent to the spermatic artery.Clamp them with micro titanium clips before cutting. For vessels that are difficult to clamp with titanium clips, use 4-0 coated braided silk to perform ligation before cutting. After ligation, suture the cremaster muscle, and both the internal and external spermatic fascia, using a 6-0 absorbable surgical suture.Using this protocol, varicocelectomy was performed on 158 males, aged 21 to 51 years, diagnosed with varicocele and decreased semen quality. The average surgery time was 100.11 minutes. Post-surgery, there was a significant overall improvement in semen quality by the third month.The progressive motility rate also increased from 20.23%to 25.84%
