In men with chronic orchialgia there appears to be wallerian degeneration in reproducible patterns in the spermatic cord nerve fibers. Transection of these nerves may explain the effect of the denervation procedure.

Microsurgical vasectomy reversal is a technically demanding procedure. Previous studies have shown the possible benefit of robotic assistance during such procedures. Our goal was to compare robotic assisted vasovasostomy and vasoepididymostomy to standard microsurgical vasovasostomy (MVV) and vasoepididymostomy (MVE). The use of robotic assistance for vasectomy reversal may provide the microsurgeon with improved visualization, elimination of tremor, and decreased fatigue and obviate the need for a skilled microsurgical assistant. This study provides the first clinical prospective control trial of robotic assisted versus pure microsurgical vasectomy reversal. The use of robotic assistance in microsurgical vasovasostomy and vasoepididymostomy may have benefit over MVV and MVE with regards to decreasing operative duration and improving the rate of recovery of postoperative total motile sperm counts based on our study.

The management of patients suffering with chronic testicular and groin pain is very challenging. With increased awareness of men's health, more patients and clinicians are open to talk about this complex problem that affects over 100,000 men/year. The pathogenesis of chronic orchialgia is still not clear, but there are several postulated theories. Treatment options include conservative medical therapy with NSAIDs, antidepressants, anticonvulsants, and narcotics. Surgical options such as targeted microsurgical denervation and microcryoablation can provide permanent durable pain relief. The goal of this article is to review and discuss the management of patients with chronic orchialgia using currently available literature.

Targeted robotic assisted microsurgical denervation of the spermatic cord is an effective, minimally invasive approach with potential long-term durability in patients with refractory chronic orchialgia.

Long-term prospective controlled trials are necessary to assess the true benefit for robotic-assisted microsurgery. The preliminary findings are promising, but further evaluation is warranted.

The increased application of the da Vinci robotic platform (Intuitive Surgical Inc.) for microsurgery has led to the development of new adjunctive surgical instrumentation. In microsurgery, the robotic platform can provide high definition 12×-15× digital magnification, broader range of motion, fine instrument handling with decreased tremor, reduced surgeon fatigue, and improved surgical productivity. This paper presents novel adjunctive tools that provide enhanced optical magnification, micro-Doppler sensing of vessels down to a 1-mm size, vein mapping capabilities, hydro-dissection, micro-ablation technology (with minimal thermal spread-CO2 laser technology), and confocal microscopy to provide imaging at a cellular level. Microsurgical outcomes from the use of these tools in the management of patients with infertility and chronic groin and testicular pain are reviewed. All these instruments have been adapted for the robotic console and enhance the robot-assisted microsurgery experience. As the popularity of robot-assisted microsurgery grows, so will its breadth of instrumentation.

Introduction:Chronic orchialgia is historically and currently a challenging disease to treat. It is a diagnostic and therapeutic challenge for physicians. Conservative therapy has served as the first line of treatment. For those who fail conservative therapy, surgical intervention may be required. We aim to provide a review of currently available surgical options and novel surgical treatment options.Methods:A review of current literature was performed using PubMed. Literature discussing treatment options for chronic orchialgia were identified. The following search terms were used to identify literature that was relevant to this review: Chronic orchialgia, testicular pain, scrotal content pain, and microsurgical denervation of the spermatic cord (MDSC).Results:The incidence of chronic orchialgia has been increasing over time. In the USA, it affects up to 100,000 men per year due to varying etiologies. The etiology of chronic orchialgia can be a confounding problem. Conservative therapy should be viewed as the first line therapy. Studies have reported poor success rates. Current surgical options for those who fail conservative options include varicocelectomy, MDSC, epididymectomy, and orchiectomy. Novel treatment options include microcryoablation of the peri-spermatic cord, botox injection, and amniofix injection.Conclusion:Chronic orchialgia has been and will continue to be a challenging disease to treat due to its multiple etiologies and variable treatment outcomes. Further studies are needed to better understand the problem. Treatment options for patients with chronic orchialgia are improving. Additional studies are warranted to better understand the long-term durability of this treatment options.
