Acute Penile Pain in Pediatric Patients

Immediate Life-Threatening Considerations

Testicular torsion is a surgical emergency requiring intervention within 6-8 hours to prevent testicular loss, characterized by abrupt onset of severe pain, negative Prehn sign, and requires immediate urological consultation 1
Testicular torsion can occur at any age and must be excluded, with a bimodal distribution peaking in neonates and postpubertal boys 1
In children with sickle cell disease, priapism presents as prolonged painful erection and requires urgent treatment if lasting more than 4 hours to prevent irreversible tissue damage 2, 3
Emergency treatment for priapism includes penile puncture, blood aspiration, saline flushing, and potential suprarenin injection if detumescence cannot be achieved 4

The American Academy of Pediatrics recommends considering the onset and duration of penile pain, with sudden onset suggesting torsion or trauma, and gradual onset suggesting infection 1
Underlying conditions such as sickle cell disease increase the risk of priapism 2, 3
Physical examination priorities include inspecting for swelling, erythema, discharge, ecchymosis, and foreskin position, as well as palpating the testicles for position, tenderness, and masses 1
Transillumination can help differentiate hydrocele from solid masses or hematomas 5

For suspected torsion or trauma, immediate urological consultation is necessary without delay for imaging if high clinical suspicion 1
Surgical exploration within 6-8 hours is recommended for torsion, and urgent repair is necessary for corpus cavernosum rupture 1
For infectious causes, warm water soaks, topical antibiotic ointment, and oral antibiotics may be used, depending on the severity of the infection 1, 3
For paraphimosis, manual reduction is the first line of treatment, and emergency urological consultation is necessary if reduction is unsuccessful 1
For priapism in sickle cell patients, hydration and analgesia are recommended for episodes less than 4 hours, and emergency intervention with exchange transfusion or leukapheresis, plus penile aspiration and irrigation, is necessary for episodes lasting 4 hours or more 2, 3, 4

Prolonged painful erection lasting > 4 hours is a urological emergency because irreversible corporal tissue damage can occur; urgent treatment is required. 6
The recommended emergency procedure consists of penile aspiration, saline irrigation, and, if detumescence is not achieved, injection of an alpha‑adrenergic sympathomimetic agent. 6

Children may experience penile or scrotal discomfort secondary to a urinary tract infection; typical laboratory findings include pyuria and bacteriuria on urinalysis. 7

Although uncommon, epididymitis can present with gradual onset of scrotal pain and swelling; abnormal urinalysis (pyuria/bacteriuria) may be present. 7
Management includes scrotal elevation and support, plus a 10‑day course of oral cephalexin (25–50 mg/kg/day divided q6–8 h). 7

This condition is usually self‑limiting and resolves within 3–10 days. 7
Recommended outpatient care: scrotal support and a follow‑up visit within 24–48 hours to confirm improvement. 7

Effective strategies include distraction (videos, games, conversation), parental presence, application of cooling sprays or ice, and comfortable positioning with scrotal support. 7

Lichen sclerosus may produce penile pain by causing foreskin tightening (phimosis) and painful erections; characteristic findings include porcelain‑white plaques, areas of ecchymosis, and fissuring. (Dermatology guideline) 8
Lichen sclerosus with striking ecchymosis can mimic signs of sexual abuse, yet the two conditions are not mutually exclusive. (Dermatology guideline) 8

All U.S. states mandate reporting of any suspected child abuse to the appropriate authorities. (CDC/MMWR recommendation) 9
When there is evidence of genital trauma, penetration, or other signs suggestive of abuse, clinicians should obtain sexually transmitted disease (STD) screening. (CDC/MMWR recommendation) 9
STD evaluation is indicated when any of the following are present: genital trauma, clinical signs of an STD, or a disclosed history of sexual abuse. (CDC/MMWR recommendation) 9
A thorough social history that includes age‑appropriate, sensitive questioning for possible abuse should be performed in all children presenting with penile pain. (CDC/MMWR recommendation) 9
If abuse is suspected, STD testing must use highly specific assays to minimize false‑positive results that could have serious legal consequences. (CDC/MMWR recommendation) 9
