High impact information on Vasovasostomy

• Sperm was noted in vasal fluid in 45.2% of the vasa during the operation and the patency rate of inguinal vasovasostomy was 88.9% [1].
• MATERIALS AND METHODS: Unilateral vasography was performed by a direct puncture technique with a lymphangiogram needle or through a partial thickness vasostomy technique in 2 groups of 10 adults Lewis rats using nonionic contrast medium mixed with methylene blue [2].
• Treatment with methylprednisolone for two months beginning at the time of the vasovasostomy resulted in a decrease in antisperm antibodies compared with nontreated vasovasostomized animals, but there was no difference in fertility between treated and nontreated vasovasostomized groups [3].
• Testes were prepared for histologic study at intervals up to seven months after vasectomy, vasectomy followed three months later by vasovasostomy, or sham operations [4].
• The Silber vasovasostomy: a method of learning the microsurgical technique [5].

Anatomical context of Vasovasostomy

• Any changes that occurred due to vasectomy and tantalum clip occlusion (e.g. testicular weight, enzyme concentrations in the testis) returned to normal within 3-6 months of vasovasostomy [6].
• After successful vasovasostomy, free carnitine levels returned to the normal range of 510.82 mumol/l. These results indicate a highly significant correlation between seminal carnitine concentrations and the anatomic site of occlusion of the epididymis [7].
• Approximately one-fourth of the testes in the vasectomy and vasovasostomy groups displayed histological changes, which consisted mainly of depletion of germ cells [8].
• In 152 men undergoing microsurgical refertilization (vasovasostomy, tubulovasostomy, microsurgical epididymal sperm aspiration, transurethral resection of the ejaculatory duct), 281 aspirates were classified intra-operatively according to Silber, and post-operatively using the Shorr staining technique [9].
• The fine structure of the vas deferens was studied by SEM and TEM after vasectomy and delayed vasovasostomy in 18 dogs [10].

Associations of Vasovasostomy with chemical compounds

• Splinted vasovasostomy. Comparison of polyglycolic acid and polypropylene sutures [11].
• Vasovasostomy restored fertility to 40-50% in vasectomized rabbits and 60-70% in the tantalum clip-occluded animals [6].
• Further clinical experience with CO2 laser in microsurgical vasovasostomy [12].
• Use of papaverine during vasovasostomy [13].
• Carbon dioxide laser microsurgical vasovasostomy [14].

Gene context of Vasovasostomy

• To determine the age or degree of sexual maturity at which a microscopic vasovasostomy is technically feasible, we collected surgical or autopsy vasa from 34 young males over a three year period, and correlated vasal size to age and Tanner stage (degree of sexual maturity ranging from 1-childhood to 5-adult) [15].
• Two more minor proteins that remained reduced after vasovasostomy were identified as prostaglandin D2 synthase and phosphatidylethanolamine-binding protein [16].
• Among these, CRISP-1 remained reduced in LF after vasovasostomy [16].
• Vas patency determined 2 months after vasovasostomy was 80% (8 of 10) in the mature group and 89% (8 of 9) in the immature group [17].
• Epididymal sperm, obtained from patients at orchiectomy and vasovasostomy were found to lack the MHS-5 antigen [18].

Analytical, diagnostic and therapeutic context of Vasovasostomy

• Experimental study of hollow, absorbable polyglycolic acid tube as stent for vasovasostomy [19].
• Experimental vasovasostomy in dogs using polyethylene tubing for splints and comparing polyglycolic acid to polypropylene sutures demonstrates the following: Polyglycolic acid sutures result in a higher vasovasostomy patency rate [20].
