Ischaemic Priapism: A Complication of Self-Administered Hyaluronic Acid Gel as an Injectable Filler for Penile Augmentation.

BACKGROUND

Injectable hyaluronic acid (HA) gel has emerged as a widely used soft tissue filler for surgeries. In penile reconstructive surgery, HA gel has been employed for penile or glans augmentation in selected patients diagnosed with micropenis. This augmentation technique involves injecting the gel into submucosal tissue and increasing the size of the penis for approximately 1 year. A few studies have investigated the possible complications correlated with medically assisted penile injections of HA gel. However, no previous reports have shown the complications of self-administered HA injection. This case report aims to present the first documented case of ischaemic priapism as a complication of self-administered HA injection.

CASE PRESENTATION: We present the case of a 43-year-old male who self-administered a 20 mL injection of HA into the dorsal side of his penis. The injected material probably reached the corpora cavernosa, leading to priapism within a few hours. However, the patient did not seek medical attention until 72 h later. The first two initial conservative attempts of blood drainage were unsuccessful because the gel had obstructed vein drainage, causing the penis to remain in a state of priapism. The final treatment approach involved shunting, high enoxaparin doses and oral Effortil administration.

CONCLUSIONS

While complications from medically assisted HA injections have been documented, this case report sheds light on the complications arising from self-administered penile injections. Priapism is a severe medical condition that requires immediate treatment to avoid potentially serious long-term consequences. Healthcare providers and patients must acknowledge its symptoms and its appropriate course of treatment, especially in the context of penile medical injections.
