(476) Contemporary Mmanagement of Penile Foreign Body Injections

Abstract Introduction Foreign body injections were first used, in the form of mineral oil, 1899 to augment men post orchidectomy for tuberculous orchitis. In 1940s and 1950s, documented cases purposeful penile foreign started be reported as “penile paraffinomas.” Their surgical correction is challenging due risk skin necrosis wound breakdown. Objective The aim study present a large case series 31 paraffinomas examine management complication rates modern era. Methods Retrospective review managed at single institution over 15-year period (2006-2021). Patient demographics, functional outcomes extracted from both paper electronic medical records. Results Median age time referral was 34 (IQR=10.5). injection 30 years (IQR=11.5). substances injected silicone (47%), paraffin (25%), oils (22%), unknown (6%). most common presenting symptoms pain (44%) but other reasons included concerns cosmesis (21%) tightness or phimosis (21%). Only 1 man presented with ulceration necrosis. Most (97%) underwent reconstruction median 2 operations per (range 1-7) 66 total. Excision primary closure possible 62% circumcision required 18% (Table 1). Closure by local tissue flap 3% split (5%) full thickness grafts sometimes required. Complications occurred 15% (n=10) being breakdown (n=6) followed (n=3). There scrotal haematoma that drainage (Clavien 3b). follow-up after last operation months 0-19 months) 70% (n=22) lost some point. Erectile dysfunction loss sensation uncommon following surgery (7%, n=2 3%, n=1 respectively). 7% (n=2) expressed dissatisfaction overall result their treatment. Conclusions Penile are rare difficult treat. Performing repeated staged revision reduces complications allowing healing between each procedure. Our consistent contemporary reports. Very few treatment despite limited severity problem. Disclosure No
