A Case of Kanamycin Self-Injection for Penile Augmentation and a Literature Review of Penile Foreign Body Injections.

Injection of various substances into the penis for augmentation is an uncommon and concerning practice that can have serious consequences, such as skin necrosis, ulcers, suboptimal cosmetic results, and persistent edema, often requiring extensive surgical repair. In this article, we present a rare case of penile self-injection with Kanamycin ointment. We describe the clinical course of the disease and the management framework that was followed. Initially managed conservatively, the patient later developed voiding difficulties and skin ulcers at the injection site. Further evaluation revealed discharging sinuses and secondary ulcers. Despite initial improvement, the wounds failed to heal adequately and required specialist referral for consideration of reconstructive surgery. The injection of foreign substances into the penis, though attempted for sexual benefits, often results in dissatisfaction and requires surgical reconstruction. Close follow-up and regular physical examination are crucial to monitor disease progression and ensure appropriate, timely management. Awareness of the harms associated with the injection of foreign substances into the penis can help reduce this practice.
