Boys are usually circumcised to prevent or treat problems such as foreskin and phimosis, reduce the risk of infection and improve hygiene. The main indications for circumcision include difficulty urinating due to phimosis, recurrent balanitis, foreskin incarceration, difficulty in hygiene and cleaning, and reducing the risk of sexually transmitted infections.
1. Difficulty urinating due to phimosis
Phimosis refers to the inability of the foreskin to evert out to expose the glans. In severe cases, it may cause difficulty in urinating or a thinning of the urine line. Long-term poor urination may cause urinary tract infection or abnormal bladder function. For such cases, doctors may recommend using erythromycin ointment to relieve inflammation, or conservative treatments such as foreskin dilation. If this is not effective, circumcision may be required. After surgery, the wound needs to be kept dry and strenuous exercise should be avoided.
2. Recurrent balanitis
Excessive foreskin can easily accumulate smegma, which can breed bacteria and cause repeated inflammation, manifested as redness, swelling, pain or increased secretion. If it occurs more than three times a year, surgical intervention may be needed. In the acute stage, clotrimazole cream combined with potassium permanganate solution can be used for soaking, but the radical cure still requires removal of the excessive foreskin. It is recommended to wear loose cotton underwear after surgery and disinfect the wound regularly.
3. Foreskin incarceration
Failure to reposition the foreskin after forcible eversion may cause incarceration, resulting in blood circulation disorder of the glans penis, severe pain and swelling. Emergency treatment requires manual reduction or incision of the stenotic ring. In the later stage, surgery is usually recommended to prevent recurrence. Incarceration for more than 6 hours may cause tissue necrosis and requires immediate medical attention. Penile erection should be avoided during the postoperative recovery period, and sedative drugs can be taken at night.
4. Difficulty in hygiene and cleaning
Excessive foreskin will make cleaning more difficult, especially after puberty, the secretion of smegma will increase, which may induce odor or infection in the partner. Daily cleaning requires turning over the foreskin and cleaning thoroughly, but some children resist care due to pain. In cases where hygiene cannot be maintained, surgery can significantly reduce the chance of urinary tract infection. It is recommended to rest in bed for the first three days after surgery and use iodophor to disinfect the wound.
5. Reduce the risk of infection
Research shows that circumcision reduces the risk of sexually transmitted infections such as HIV, as well as penile cancer and cervical cancer in the female partner. However, surgery is not absolutely necessary and requires comprehensive evaluation of individual circumstances. Sexual intercourse is prohibited within 6 weeks after surgery. If bleeding or fever occurs during the recovery period, timely follow-up is required.
Postoperative care requires keeping the wound clean and dry, and rinsing it with saline every day to avoid urine contamination. Eat a light diet and consume more oranges and kiwis, which are rich in vitamin C, to promote healing. Wear loose-fitting clothing during recovery and avoid frictional activities such as cycling. If abnormal bleeding, suppuration or persistent pain occurs, you should return to the hospital for examination immediately. Those who have not had surgery should keep opening and cleaning their skin every day, teach children the correct cleaning methods, and seek medical attention promptly if they find redness, swelling or itching.
