Phimosis Surgery: Benefits, Risks & Aftercare

Phimosis surgery is usually done through circumcision, a procedure that removes the foreskin so the head of the penis can be exposed. It may be recommended when phimosis causes pain, trouble urinating, recurrent infections, or does not improve with other treatments.

Phimosis surgery is performed by a urologist or pediatric urologist using local or general anesthesia, depending on the person’s age and medical needs. The procedure is usually simple and quick, and it may help lower the risk of penile infections, urinary tract infections, penile cancer, and some sexually transmitted infections.

Recovery from phimosis surgery is usually fast, with pain and bleeding improving within about 10 days when wound care instructions are followed. Possible risks include bleeding, infection, narrowing of the urethral opening, uneven foreskin removal, or the need for another surgery, although these complications are uncommon.

How it's done

Phimosis surgery is performed by a urologist, or by a pediatric urologist in children, using local or general anesthesia depending on the patient’s age and health needs.

It is usually a simple and quick procedure that involves removing excess foreskin so the glans, or head of the penis, can be exposed.

A penile nerve block may also be used during the procedure to numb the area and prevent pain or discomfort. This helps keep the patient comfortable throughout the surgery.

Benefits of surgery

The goal of phimosis surgery is to remove the foreskin, or excess skin that covers the head of the penis. This makes it easier to expose and clean the glans, which may offer health benefits such as:

• Lower risk of penile infections, such as yeast infections
• Lower risk of urinary tract infections in men (UTIs)
• Lower risk of penile cancer

According to the CDC, male circumcision reduces the risk of HIV infection and certain STIs among heterosexual men, including high-risk genital HPV infection and genital herpes. However, it does not replace condom use, as condoms remain the most effective way to reduce the risk of STIs during sex.

Recovery and wound care

Recovery after phimosis surgery is usually straightforward, although healing time can vary depending on age. According to the American Academy of Pediatrics, the penis is usually fully healed about 1 week to 10 days after circumcision, while the NHS states that adult circumcision may take 4 to 6 weeks to fully heal.

During healing, nocturnal erections may cause mild discomfort or light bleeding, which is one reason the procedure may be easier to recover from in childhood.

After surgery, the doctor may recommend changing the dressing the next morning. To do this, the gauze should be gently removed and the area should be washed carefully with soap and water, without rubbing the wound or causing bleeding. The prescribed ointment should then be applied, and the area should be covered again with sterile gauze to keep it clean and dry.

Stitches may dissolve on their own or be removed by the doctor, depending on the type used.

To support recovery after circumcision, it is generally recommended to:

• Avoid physical exertion or strenuous activity for the first 3 days, and rest as much as possible
• Apply an ice pack to the area to reduce swelling or relieve pain
• Take pain medicine as prescribed by the doctor
• Avoid sex for at least 1 month after surgery, or until cleared by the doctor

After the healing period and proper wound care, the final results of the surgery can usually be seen.

Possible risks 

Phimosis surgery is usually performed in a hospital setting and has a low risk of complications. It is generally well-tolerated, and recovery is often quick.

Although rare, possible complications include bleeding, infection, narrowing of the urethral opening, removing too much or too little foreskin, uneven healing, or the need for another surgery.
