The clinical application and research on vas deferens laser coagulation sterilization / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of Ar(+) laser on human vas deferens and to compare the effects of using different radiation levels with varying thickness of tissue and varying levels of injury.</p><p><b>METHODS</b>After initial tests on animals, four human scrotums were opened and treated directly with Ar(+) laser radiation. Then 58 human individual scrotums were treated with radiation by the method of trans-skin puncture. The rate of sperm reduction and elimination was tested.</p><p><b>RESULTS</b>In 60 cases, the sperms were found to be eliminated completely after six months of radiation treatment. In 2 cases the sperms were found not to be eliminated completely due to the insufficient radiation.</p><p><b>CONCLUSION</b>Ar(+) laser is one of the best forms of radiation for coagulation of vas deferens. It can be used to coagulate vas deferens without any complications or sequelae.</p>
