“…Thus, there is a significantly increased time investment for robotic reversal at this point. This was also found to be the case by Kuang et al [8,9]. However Schiff et al [10,11] found that the robotic platform cut down operative times in an animal model.…”

“…Microsurgical vasectomy reversal is one such procedure that can be technically demanding. A number of groups have developed robotic assisted techniques to perform vasovasostomy and vasoepididymostomy in animal and ex-vivo human models [8,9,10,11]. Some studies suggest robotic assisted reversal may have advantages over microsurgical reversal in terms of ease of performing the procedure and improved patency rates [10,11].…”

Human robotic assisted bilateral vasoepididymostomy and vasovasostomy procedures: initial safety and efficacy trial

Our goal was to develop a robotic approach for vasoepididymostomy (RAVE) and vasovasostomy (RAVV) using a 4 arm High Definition Platform (Intuitive Surgical, CA) and present our human in-vivo results. All 3 RAVV procedures were successful and one patient had 102 million motile sperm/ml of ejaculate at 1 month post-op. The RAVE procedure patient only had a few non-motile sperm at 6 month follow up in his ejaculate. The use of robotics seems to offer advantages in terms of ergonomics and suture control. Further evaluation is needed to assess the clinical potential of robotics in vasectomy reversal.

“…Fleming et al , first reported robot assisted bilateral vasovasostomies on two patients with excellent patency results (18). In 2005, multilayered RAVR was performed in a rabbit model (19). In 2010, the first comparative human study was published between RAVR and traditional microsurgical vasectomy reversal and showed shorter operative times and improvement in early semen analysis measurements in the RAVR group compared to microsurgical vasectomy reversal group, by a single surgeon (20).…”

Chronic orchialgia is one of the most common complaints seen in the urologists office and has traditionally been considered a very difficult diagnostic and therapeutic challenge for the clinician. First line management of chronic orchialgia is conservative treatment; however, in men who fail conservative therapy, surgical intervention may be indicated. Microsurgery has been the mainstay for surgical treatment of chronic orchialgia, but the implementation of robotics to microsurgery lends itself particularly to surgical treatment of chronic orchialgia. PubMed was used to perform a current literature search on chronic orchialgia with robotic microsurgery, robotic spermatic cord denervation, robotic varicocelectomy, and robotic vasectomy reversal. Although conservative therapy is considered the first line treatment for chronic orchialgia, reported outcomes are moderate to poor, with the need to proceed to surgical intervention in select cases. Current surgical therapies in which robot assistance have been applied to microsurgery include microsurgical denervation of the spermatic cord, varicocelectomy, and vasectomy reversal. As further studies have assisted in the understanding of surgical treatment of chronic orchialgia, the application of robot assistance to this level of microsurgery has been shown to be feasible and safe with comparable outcomes to traditional microsurgery and may provide potential advantages.

“…Although detailed information on the rate of sperm clearance from the ejaculate after vasectomy remains sparse, time since vasectomy rather than number of ejaculations is more predictive of sperm clearance. 85,86 Reversibility is better with microsurgery 83 in younger men with shorter duration since vasectomy 82 and possibly with longer testicular vasal stump 87,88 ; unfavorable predictors include nonmicrosurgical techniques, older age of wife (especially after 40 years of age), 83,89 high titers of sperm antibodies, 81 and long duration since vasectomy 90,91 due to long-term epididymal, 92 vasal, 93 and testicular damage. Complications of vasectomy include postsurgical bleeding, wound or genitourinary infections and fistulae, as well as chronic scrotal pain, 35,66 with the risk for death estimated at ∼1 per million vasectomies in developed countries, although it is higher in developing countries.…”
