What are the common causes of balanoposthitis?

Patient's question:

A week ago, the redness and swelling of the glans had already started to reappear, with some itching. I didn't pay much attention to it. Yesterday, it started to develop pus in some areas, and it became very painful when wearing clothes or accidentally touching it. What are the common causes of balanoposthitis?

Doctor's answer:

Treatment with Medication
1. Local Treatment Always maintain local cleanliness to prevent irritation. Use anti-inflammatory drugs for soaking or wet dressing. For cases where purulent fluid in the preputial sac cannot drain properly, perform longitudinal incision and drainage of the prepuce along the back, followed by cleaning and post-infection control circumcision.
2. Special Treatment For infections with clear etiology, implement specific solutions. For candidal balanitis, local treatment is applied. For Trichomonas vaginalis infections, oral anti-inflammatory drugs can be administered.
3. Systemic Treatment When the patient has severe infection, suspected necrotizing balanitis, accompanied by fever and inguinal lymphadenopathy, systemic antibiotics should be used.
