Microanatomy of the spermatic cords during microsurgical inguinal varicocelectomy: initial experience in Asian men.

ABSTRACT: The microanatomy of the inguinal spermatic cords has never been reported in Asia. The purpose of this study was to describe the number and relationship of the veins, arteries and lymphatics in the spermatic cord and to clarify the location of the vas deferens in Asian men. Fifty-one patients receiving 79 primary microsurgical varicocelectomies performed by a single surgeon from April 2011 to July 2012 were studied. The number of internal and external spermatic veins, testicular arteries and lymphatic channels preserved during the inguinal microsurgical varicocelectomy were recorded. The relationship between the right and left vascular anatomy during bilateral varicocelectomies was evaluated. The data showed that mean numbers of 1.5±0.9 arteries, 5.6±2.2 spermatic veins and 3.6±1.9 lymphatics were identified during the repairs. The internal spermatic arteries were surrounded by a dense complex of adherent veins in 81.2% of the cases. The external spermatic vein or veins were found in 60.8% of the cases. The vas deferens may be contained within the internal spermatic fascia. The results suggest that the number of veins may be highly variable and less than those reported in the English literature, but there is some similarity in the inguinal microanatomy of the right and left spermatic cords. Further research is warranted to clarify our results.

Project description:BackgroundVaricocele (VC) is one of the most common causes of infertility in men, and microscopic varicocelectomy is currently the major surgical procedure for VC. We assessed the clinical effectiveness of microsurgical subinguinal varicocelectomy (MSV) with enhanced recovery after surgery (ERAS) in the treatment of VC in terms of semen quality improvement rate, pregnancy rate, pain relief rate, recurrence rate, and complication rate after MSV and explored the indications for VC surgery.MethodsIn total, 216 patients undergoing MSV in our center between June 2019 and July 2020 were enrolled in this study. All patients received the surgery under local anesthesia and were admitted and discharged within 24 hours. All patients were followed up for more than 6 months, and the rates of semen quality improvement, pregnancy, pain relief, recurrence, and postoperative complications were recorded. We can evaluate the pain degree of patients through the numerical rating scale (NRS). (I) 0 points for painless; (II) 1-3: mild pain; (III) 4-6: moderate pain; (IV) 7-10 points are severe pain. 0 is the most slightly, indicating comfort, and 10 is the most painful and unbearable.ResultsThe sperm concentration, total sperm count, progressive motility rate, sperm viability, and morphology were significantly improved after the surgery (all P values <0.05). The rate of semen quality improvement was 88.2%, and the semen indicators returned to normal in 26.6% of the patients. Among the patients who were followed up for 1 year, the natural conception rate reached 27.1% and was accompanied by a 95.5% pain relief rate, a 0.5% VC recurrence rate, and a 2.3% postoperative complication rate.We obtained data through laboratory examination of semen DNA fragments index (DFI). Compared with preoperative and postoperative DFI, postoperative DFI was improved, and the pregnancy outcome was improved.ConclusionsMSV under local anesthesia increases the rates of semen quality improvement, pregnancy, and pain relief while lowering the rates of recurrence and postoperative complications. MSV may also help to improve the pregnancy outcomes in patients with VC accompanied by sperm DNA fragmentation or nonobstructive azoospermia, but this should be verified by further investigation.

Project description:BackgroundAlthough the tearing of tissues during castration is forbidden in the EU, it is still routinely applied in many countries. The goal of this study was to evaluate vocalizations and movements of male piglets undergoing castration by applying different techniques and pain treatments based on scores under practical conditions (Trial 1, n = 50) and to investigate anatomical features after castration of dead piglets with different techniques (Trial 2, n = 28).ResultsIn Trial 1, treatment groups did not significantly influence the duration of castration. Both the duration of vocalization and the scores for vocalizations and movements were lower in piglets castrated under general anesthesia (P < 0.05). Behavior scores in conscious piglets did not differ. The incision and extraction caused lower vocalizations and movements than the pulling and severing of spermatic cords (P < 0.01). Movements were more intense during tearing of the spermatic cords than during cutting at the first and second severing (P < 0.01). In both trials, the remains of spermatic cords protruded tendentially more often from castration wounds after severing by tearing (P < 0.09). In Trial 2, the minimum, mean and maximum lengths of the testicles and spermatic cords were extended when severing was realized by tearing (P < 0.01). The mean relative testicle weight of 1.05‰ in dead piglets castrated by tearing was larger than that in dead piglets castrated by cutting (0.91‰) (P < 0.05).ConclusionsThe trials uncovered significant differences between behavior expressed by piglets castrated by tearing or cutting, indicating a higher pain level in the tearing group. It was found that the castration technique tearing increased the amount of removed tissues and might cause intraabdominal damage to the remaining tissues and vessels in a yet unknown dimension. These findings should be considered for implementation and stricter enforcement of the ban on tearing for castration.
