          Abstract

          Introduction

          Traumatic neuroma is a reactive process caused by the regeneration of an injured nerve that usually forms a nodular proliferation of small nerve bundles. Penile traumatic neuroma is rare; only a few cases related to circumcision have been reported.

          Aim

          To report on a case of traumatic neuroma in the penis after selective dorsal neurotomy (SDN) to treat premature ejaculation.

          Methods

          The penile traumatic neuroma was successfully removed by excision and confirmed by histopathology.

          Results

          A 55-year-old man who had had several painless, slow-growing nodules on his penis for 2 years presented to our hospital. He had no history of genital trauma, urinary tract infection, or penile surgery, except SDN to treat premature ejaculation. The nodules were excised and the final diagnosis was traumatic neuroma. No recurrence has been detected during 1 year of follow-up.

          Conclusion

          The main complications of SDN are recurrence of premature ejaculation, pain or paresthesia on the glans penis, and erectile dysfunction. However, no traumatic neuroma has been reported as a complication. We report that a traumatic neuroma can occur after SDN.

          International Society for Sexual Medicine's guidelines for the diagnosis and treatment of premature ejaculation.

          Over the past 20 years our knowledge of premature ejaculation (PE) has significantly advanced. Specifically, we have witnessed substantial progress in understanding the physiology of ejaculation, clarifying the real prevalence of PE in population-based studies, reconceptualizing the definition and diagnostic criterion of the disorder, assessing the psychosocial impact on patients and partners, designing validated diagnostic and outcome measures, proposing new pharmacologic strategies and examining the efficacy, safety and satisfaction of these new and established therapies. Given the abundance of high level research it seemed like an opportune time for the International Society for Sexual Medicine (ISSM) to promulgate an evidenced-based, comprehensive and practical set of clinical guidelines for the diagnosis and treatment of PE. Develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. Method.  Review of the literature. This article contains the report of the ISSM PE Guidelines Committee. It affirms the ISSM definition of PE and suggests that the prevalence is considerably lower than previously thought. Evidence-based data regarding biological and psychological etiology of PE are presented, as is population-based statistics on normal ejaculatory latency. Brief assessment procedures are delineated and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. Therefore, it is strongly recommended that these guidelines be re-evaluated and updated by the ISSM every 4 years. © 2010 International Society for Sexual Medicine.

            An update of the International Society of Sexual Medicine's guidelines for the diagnosis and treatment of premature ejaculation (PE).

            In 2009, the International Society for Sexual Medicine (ISSM) convened a select panel of experts to develop an evidence-based set of guidelines for patients suffering from lifelong premature ejaculation (PE). That document reviewed definitions, etiology, impact on the patient and partner, assessment, and pharmacological, psychological, and combined treatments. It concluded by recognizing the continually evolving nature of clinical research and recommended a subsequent guideline review and revision every fourth year. Consistent with that recommendation, the ISSM organized a second multidisciplinary panel of experts in April 2013, which met for 2 days in Bangalore, India. This manuscript updates the previous guidelines and reports on the recommendations of the panel of experts. The aim of this study was to develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. A comprehensive literature review was performed. This article contains the report of the second ISSM PE Guidelines Committee. It offers a new unified definition of PE and updates the previous treatment recommendations. Brief assessment procedures are delineated, and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. We again recommend that these guidelines be reevaluated and updated by the ISSM in 4 years. © 2014 International Society for Sexual Medicine.

              Selective resection of dorsal nerves of penis for premature ejaculation.

              Premature ejaculation (PE) is one of the most prevalent male sexual dysfunctions. Selective resection of the dorsal nerve (SRDN) of penis has recently been used for the treatment of PE and has shown some efficacy. To further clarify the efficacy and safety of SRDN on PE, we performed a preliminary, randomized, placebo-controlled clinical observational study. Persons with the complaints of rapid ejaculation, asking for circumcision because of redundant foreskin, intravaginal ejaculation latency time (IELT) within 2 min, not responding to antidepressant medication or disliking oral medication were randomly enrolled in two groups. From April 2007 to August 2010, a total of 101 eligible persons were enrolled, 40 of them received SRDN which dorsal nerves of the penis were selectively resected, and those (n = 61) enrolled in the control group were circumcised only. IELT and the Brief Male Sexual Function Inventory (BMSFI) questionnaire were implemented pre- and post-operatively for the evaluation of the effect and safety of the surgery. There are no statistically significant differences in the baseline data including mean ages, mean IELTs, perceived control abilities and the BMSFI mean scores between the two groups. With regard to the post-operative data of the surgery, both IELTs and perceived control abilities were significantly increased after SRDN (1.1 ± 0.9 min vs. 3.8 ± 3.1 min for pre- and post-operative IELT, respectively, p 0.05). Also, there were no statistically significant differences both in BMSFI composite and subscale scores between the two groups after surgery. Hence, we conclude that SRDN is effective in delaying ejaculation and improving ejaculatory control, whereas erectile function is not affected. The results imply that SRDN may be an alternative method for the treatment of PE for some patients. © 2012 The Authors. International Journal of Andrology © 2012 European Academy of Andrology.
