Balanitis is inflammation of the glans penis[1] and is a common condition affecting an estimated 3-11% of males. Balanitis can occur in males at any age. Morbidity is associated with the complications of phimosis.[2, 3, 4] Balanitis involving the foreskin and prepuce is termed balanoposthitis. According to European guidelines outlining the current management of balanoposthitis, the aims of management are to minimize sexual dysfunction and urinary dysfunction, exclude penile cancer, treat premalignant disease, and diagnose and treat STIs.
Predisposing factors include poor hygiene and overwashing, use of over-the-counter medications, and nonretraction of the foreskin.[5] Though uncommon, a complication of balanitis (usually only in recurrent cases) is constricting phimosis, or inability to retract the foreskin from the glans penis. Other complications of balanitis may include meatal stenosis and possible urethral strictures; urinary retention; and vesicoureteral reflux.
Balanitis xerotica obliterans (BXO), or penile lichen sclerosus, is a progressive sclerosing inflammatory dermatosis of the glans penis and foreskin. BXO is uncommon in children.[2, 3, 4, 6, 7, 8, 9, 10]
Uncircumcised men with poor personal hygiene are most affected by balanitis. Lack of aeration and irritation because of smegma and discharge surrounding the glans penis causes inflammation and edema. Though uncommon, complications of balanitis include phimosis and cellulitis. Meatal stenosis with urinary retention may rarely accompany balanitis. In very few cases, balanitis may contribute to the "buried penis syndrome." Diabetes is the most common underlying condition associated with adult balanitis.[11, 12, 13] Older age has been identified as a risk factor for candidal balanitis. Zoon’s balanitis is a disease of older men who are uncircumcised.[5]
If the patient is able to retract the foreskin and does not have uncontrolled diabetes, he may be discharged to follow up with a urologist.
Bacitracin should be used for children, and clotrimazole in adults, and possibly a steroid cream.

Patients with balanitis usually present with the following complaints:
Penile discharge
Pain or difficulty with retraction of foreskin
Impotence
Difficulty urinating or controlling urine stream (in very severe cases)
Inability to insert a Foley catheter
Tenderness and erythema of the glans penis
Itching
Systemic symptoms such as fever and nausea are uncommon
Observe the patient with balanitis for the following signs and symptoms:
Signs of sepsis
Uncontrolled diabetes
Inability to retract foreskin
Inability to urinate
Physical examination findings may include the following:
Erythema and edema of glans penis or foreskin
Foul odor
Discharge
Ulceration and/or plaques
Phimosis (uncommon)
Signs of urinary obstruction (rare)
Meatal stenosis
Bladder distension
Ballooning of the foreskin when voiding
Lymphadenopathy
Diabetes is the most common underlying condition associated with adult balanitis.[11] In a study of patients with type 2 diabetes mellitus, treatment with dapagliflozin (2.5 mg, 5 mg, or 10 mg once daily) was found to be associated with an increased risk of vulvovaginitis or balanitis, related to the induction of glucosuria. According to the authors, events were generally mild to moderate, were clinically manageable, and rarely led to discontinuation of treatment. For dapagliflozin 2.5 mg, 5 mg, and 10 mg, infections were reported in 4.1%, 5.7%, and 4.8% of patients, respectively, as compared to 0.9% in patients with type 2 diabetes who were given placebo.[14, 15]
Other causes include the following[16] :
Poor personal hygiene
Chemical irritants (eg, soap, petroleum jelly)
Edematous conditions, such as congestive heart failure (right-sided), cirrhosis, and nephrosis
Drug allergies (eg, tetracycline, sulfonamide)
Morbid obesity
Several organisms and viruses cause balanitis, including the following:
Candidal species (most commonly associated with diabetes)
Group B and group A beta-hemolytic streptococci
Neisseria gonorrhoeae
Chlamydia species
Anaerobic infection
Human papilloma virus
Gardnerella vaginalis
Treponema pallidum (syphilis)
Trichomonal species
Borrelia vincentii and Borrelia burgdorferi
Balanitis xerotica obliterans (lichen sclerosus) is a chronic dermatosis identified by whitish plaques involving the glans and foreskin (shown in the image below).[2, 3, 17]
Zoon balanitis is a reddish velvety lesion on the glans.[18, 19, 20] It is typically found in older, uncircumcised males. It can be asymptomatic or pruritic or may cause dysuria.[21]
Reiter disease consists of circinate and eroding lesions on the glans.
Complications of balanitis may include meatal stenosis and possible urethral strictures; urinary retention; and vesicoureteral reflux.
In a study of 250 patients after circumcision for balanitis xerotica obliterans (lichen sclerosus), approximately 20% required a subsequent operation for meatal stenosis. According to the authors, precircumcision topical steroids may help decrease this rate of subsequent meatal pathology. They added that submission of the foreskin for histologic analysis should always be considered, because the prognosis differs for lichen sclerosus and nonlichen sclerosus histology. Those patients with balanitis xerotica obliterans who later underwent meatal procedures rarely underwent a meatal procedure at circumcision and were less likely to have received preoperative topical steroids, as compared to patients who did not need a subsequent meatal procedure.[22]
Laboratory studies for uncomplicated balanitis are not typically necessary but may include the following, when clinically appropriate:
Serum glucose test (as part diabetes screening)
Culture of discharge
Syphilis serology test
Wet mount
Potassium hydroxide (for Candida)
HIV and human papilloma virus titers in selected cases
Ultrasonography or bladder scan is used to detect urinary obstruction in severe balanitis.
Patients presenting with balanitis but without phimosis should receive the following recommendations and treatment[5, 23] :
Gentle retraction of the foreskin daily and soak in warm water to clean penis and foreskin.
In pediatric patients and patients with mild balanitis xerotica, a 2-month trial of antifungals may be attempted; the patient or mother should retract the foreskin gently and apply 0.05% betamethasone twice a day. This applies to children older than 3 years. Success is seen particularly in male children older than 10 years compared with those aged 3-10 years. Success ranges from 65-95%.
Topical steroids have had only limited success in patients with moderate-to-severe balanitis xerotica obliterans. These patients are more likely to have distal scarring of the foreskin.
In recurrent cases, 1% pimecrolimus cream was used instead of steroids, with a 64% success rate.[24]
Apply bacitracin (not Neosporin) for pediatric patients if bacterial infection is suspected.
Apply topical clotrimazole for adult men with probable candidal balanitis.
Obtain a culture of discharge in complicated cases such as those with associated cellulitis, then treat empirically with appropriate antibiotics (typically first-generation cephalosporin).
A study of 1185 boys concluded that fluticasone proprionate 0.05% was effective and safe in treating associated phimosis, with successful results in 91.1% of patients.[25]
Patients presenting to the ED with phimosis and severe urinary obstruction as a complication of balanitis should receive the following care (recommended that surgical intervention be performed by a urologist, if available):
Steroid cream and gentle retraction of the foreskin, if the phimosis is not too tight, may be used before surgery is contemplated.[26, 27]
Without damaging the glans penis, dilate the foreskin using a clamp. If the glans penis is adherent to the foreskin, the procedure may be contraindicated. Local anesthesia, analgesia, and/or sedation may be required.
Perform a dorsal slit incision by cutting the foreskin over the dorsal shaft of the penis to enlarge the foreskin opening. This procedure requires local anesthesia and, possibly, sedation.
Perform a formal circumcision (preferably in the operating room).[28, 29]
Circumcision is not a preventive treatment of balanitis in those younger than 3 years.
Consult a urologist if a dorsal slit incision or circumcision is contemplated.
Deterrence/prevention of balanitis includes the following measures:
Proper personal hygiene
Control of diabetes and other chronic medical disorders
Weight reduction for patients who are obese
If the patient is able to retract the foreskin and does not have uncontrolled diabetes, he may be discharged to follow up with a urologist.
Circumcision should only be suggested, if the patient fails outpatient conservative therapy, particularly in children.
Patients should receive the following instructions:
Topical therapy - Bacitracin in children and clotrimazole in adults and possibly a steroid cream
Education - Improve personal hygiene by retracting the foreskin daily and cleaning the glans penis with water
European guidelines have been published regarding management of specific balanitides[5] :
The goal of balanitis therapy is to eradicate infection and prevent complications.
Therapy must cover all likely pathogens in the context of the clinical setting.
Broad-spectrum antifungal agent that inhibits yeast growth by altering cell membrane permeability. For adult use, especially those with a positive history of candidiasis in a sexual partner.
Prevents transfer of mucopeptides into growing cell wall, which inhibits cell wall synthesis and bacterial growth. More commonly used in pediatric patients or patients who are not sexually active.
These agents have anti-inflammatory properties and cause profound and varied metabolic effects. Corticosteroids modify the body's immune response to diverse stimuli.
For treatment of inflammatory dermatoses responsive to steroids. Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing capillary permeability. Affects production of lymphokines and has inhibitory effect on Langerhans cells.
Regulates key factors responsible for the immune response.
First nonsteroid cream approved in the US for mild-to-moderate atopic dermatitis. Derived from azcomycin, a natural substance produced by fungus Streptomyces hygroscopics var. ascomycetous. Selectively inhibits production and release of inflammatory cytokines from activated T-cells by binding to cytosolic immunophilin receptor macrophilin-12. The resulting complex inhibits phosphatase calcineurin, thus blocking T-cell activation and cytokine release. Cutaneous atrophy was not observed in clinical trials, a potential advantage over topical corticosteroids. Indicated only after other treatment options have failed.
