Infertility & Sexual Dysfunction(구연) (E-195) 조루 치료를 위한 자가지방을 이용한 귀두확대술과 배부신경차단술의 치료 효과 비교 예작병원 홍성우, 박상호, 성병주, 문일 Introduction and Objective: Although guidelines from the American Urological Association and European Association of Urology do not consider surgical treatment for premature ejaculation, the use of glans penis augmentation and dorsal neurectomy has increased for many years in Korea. Thus, this study was aimed to evaluate the difference between the two surgical procedures, glans penis augmentation and dorsal neurectomy, in patients with premature ejaculation. Materials and Methods: From January 2018 to December 2019 a total of 74 patients [31 patients (group A) who underwent glans penis augmentation, and 43 patients (group B) who underwent dorsal neurectomy] who were able to follow up more than 3 months conducted by a single surgeon were compared and analyzed using the Premature Ejaculation Diagnostic Tool (PEDT) questionnaire at Pre-op and 3-month follow-up visits. Glans penis augmentation was performed using autologous fat, and the 12 o'clock position was approached by puncture with a 17G needle. Dorsal neurectomy was approached through the previous circumcision line and approximately 1cm nerve stump was cut off. Results: There was no difference in age and basic medical history between the two groups. The Pre-op mean PEDT questionnaire score was 16 points in group A and 17 points in group B, which was slightly higher in group B, but there was no statistically significant difference. In the PEDT questionnaire conducted 3 months after surgery, group A showed mean 8 points (range 4~12) and group B improved mean 9 points (range 6~13), but there was no statistical difference between the two groups. Conclusions: Both two surgical procedures have proven effective treatment for premature ejaculation patients in our clinic. However, over time, therapeutic effect may be disappeared due to the absorption of fat and the regeneration of dissected nerves, so long-term study is needed to compare the more accurate treatment effect between the two groups. keywords : Premature Ejaculation, Glans Penis Augmentation, Dorsal Neurectomy
