TL;DR: This surgical technique, using Moon's clamp, may be effective in reducing the operative time, the postoperative complications and the recovery time after different types of vas surgeries, such as vasectomy or vasectomy reversal.
Abstract: Introduction We have recently designed a novel surgical instrument, a double-ringed clamp (Moon's clamp), with which the vas deferens can be located and isolated both simply and safely while minimizing unnecessary injury to the surrounding tissue.

TL;DR: This guideline was peer reviewed by 55 independent experts during the guideline development process and recommended that vasectomy be considered for permanent contraception much more frequently than is the current practice in the U.S. and many other nations.

TL;DR: This clinical update discusses patient evaluation, variables that may influence reversal success rates, factors to consider in choosing to perform vasovasostomy versus vasoepididymostomy, and the usefulness of vasectomy reversal to alleviate postvasectomy pain syndrome.
Abstract: Vasectomy is a safe and effective method of contraception used by 42-60 million men worldwide. Approximately 3%-6% of men opt for a vasectomy reversal due to the death of a child or divorce and remarriage, change in financial situation, desire for more children within the same marriage, or to alleviate the dreaded postvasectomy pain syndrome. Unlike vasectomy, vasectomy reversal is a much more technically challenging procedure that is performed only by a minority of urologists and places a larger financial strain on the patient since it is usually not covered by insurance. Interest in this procedure has increased since the operating microscope became available in the 1970s, which consequently led to improved patency and pregnancy rates following the procedure. In this clinical update, we discuss patient evaluation, variables that may influence reversal success rates, factors to consider in choosing to perform vasovasostomy versus vasoepididymostomy, and the usefulness of vasectomy reversal to alleviate postvasectomy pain syndrome. We also review the use of robotics for vasectomy reversal and other novel techniques and instrumentation that have emerged in recent years to aid in the success of this surgery.

TL;DR: Intra-operative local MMC in vasovasostomy can be regarded as a safe and efficient technique which has several advantages including lower cost and increase of sperm count that is more prominent when the interval between vasectomy and reversal is 5-10 years.
Abstract: Background: Two-six percentage of vasectomized men will ultimately seek vasectomy reversal, which late stricture and obstruction after operation are relatively common. To find a method for improving vasovasostomy outcomes, we used intra-operative local mitomycin-C (MMC) preventing possible fibrosis and stricture. Materials and Methods: In this randomized clinical trial, 44 patients were assigned to two groups randomly during a one-year study and the data of 40 patients were analyzed. The patients were followed up for 6 months after surgery. The case group (n=19) was treated by vasovasostomy with intra-operative local MMC. The control group (n=21) underwent standard vasovasostomy. Results: Mean sperm count in MMC group was significantly higher than the controls. The sperm count of more than 20 million/ml was respectively 53 and 14 in MMC and control groups. In a subgroup where the interval between vasectomy and reversal was 5-10 years, post-reversal azoospermia was absent in MMC group, but 50 of the controls were still azoospermic. In addition, 80 of MMC group had more than 20 million/ml sperms, but all of the controls had less than 20 million/ml sperms. No significant complication was seen. Conclusion: Intra-operative local MMC in vasovasostomy can be regarded as a safe and efficient technique which has several advantages including lower cost. Increase of sperm count is the main effect of local MMC application that is more prominent when the interval between vasectomy and reversal is 5-10 years (Registration number: IRCT2015092324166N1). © 2019, Royan Institute (ACECR).

TL;DR: Ambulatory mini-incision microsurgical vasectomy reversal using Moon's clamp and under local anaesthesia is a surgically feasible option that offers the advantages of a low-risk operation and allows patients to return to their daily activities quickly with minimal complications.
Abstract: INTRODUCTION In line with the effort to evaluate feasible surgical options for vasectomy reversal and to increase patients’ willingness to undergo the procedure, this study reported on a technique for ambulatory mini-incision microsurgical vasovasostomy using a double-ringed clamp (i.e. Moon’s clamp). This technique does not require the use of dilators, approximators and other accessory devices.
