Urgent Care Evaluation of Pain and Swelling in the Scrotum
What Urgent Care Clinicians Need to Know
Testicular pain accounts for 0.5% of emergency department visits annually in the United States and is a common presenting concern in acute care settings, including urgent care. This issue presents a systematic, evidence-based approach to the urgent care evaluation and management of scrotal or testicular complaints, including sensitive history-taking and physical examination, appropriate use of laboratory testing and ultrasonography, diagnosis and initial management of common conditions, and identification of patients who require referral to a specialist or the emergency department.
Testicular torsion is the most worrisome cause of acute testicular pain, and testicular salvage is greatest within the first 6 hours of symptom onset, so surgical intervention should never be delayed for imaging when torsion is strongly suspected. The issue also covers epididymo-orchitis, testicular cancer, hydrocele, spermatocele, varicocele, trauma, and rarer causes of scrotal pain and swelling.
Why This Topic Matters in Urgent Care
- Testicular pain and swelling range from benign conditions to time-sensitive urologic and surgical emergencies, and testicular torsion should be treated as emergent until proven otherwise.
- Testicular torsion was the fourth most common diagnosis associated with litigation in a review of pediatric malpractice claims, underscoring the medicolegal and health risks of missed or delayed diagnosis.
- No single history finding, physical examination sign, or ultrasound result can reliably confirm or exclude testicular torsion in isolation, so clinical suspicion should guide urgent referral rather than any one test.
- Sensitive history-taking and a chaperoned, respectful physical examination are essential to accurate evaluation and require deliberate attention to patient comfort, dignity, and trust.
- Recognizing which patients can be safely managed in urgent care versus which require emergency transfer or specialist referral is central to preventing testicular loss, impaired fertility, and other complications.
Clinical Content at a Glance
Clinical Q&A
- How can clinicians approach sensitive history-taking and physical examination while maintaining patient comfort, dignity, and trust?
- Clinicians should explain the purpose of personal questions and the examination, offer a chaperone in accordance with institutional policy, ask guardians or partners to step out when appropriate to allow candid disclosure, and use clear, nonjudgmental, age-appropriate language throughout.
- Which clinical examination findings are most useful when evaluating a patient with testicular or scrotal pain?
- Key findings include the Brunzel sign, Ger sign, cremasteric reflex, whirlpool sign on ultrasound, Prehn sign, blue dot sign, and cough impulse, but no single finding should be used alone to confirm or exclude testicular torsion.
- Which patients can be safely managed in urgent care, and which require emergency transfer or specialist referral?
- Patients with concerning symptoms such as sudden or severe pain, nausea or vomiting, abnormal physical examination findings, significant trauma, or serious infection require immediate transfer to an emergency department with surgical and urology capability, while stable patients with conditions such as uncomplicated epididymitis or epididymo-orchitis may be treated and discharged from urgent care with appropriate follow-up.
- What is the best way to risk-stratify a patient with suspected testicular torsion to determine if ultrasound is needed?
- The Testicular Workup for Ischemia and Suspected Torsion (TWIST) score can assist with risk stratification, but scores should not be relied upon alone to exclude torsion, and any patient with a high-risk score or strong clinical suspicion should be urgently referred.
- How does management of epididymo-orchitis differ based on a patient's sexual practices?
- Rather than using age alone to guide antimicrobial selection, clinicians should consider the patient's sexual practices and exposures, since patients who engage in receptive anal intercourse are at higher risk for enteric organisms in addition to gonorrhea and chlamydia.
Case Snapshots
CASE 1 — Testicular Torsion Presenting as Abdominal Pain:
A 14-year-old boy reports lower abdominal pain, but after his mother steps out for a chaperoned exam, he describes sudden left testicular pain with nausea; exam reveals a high-riding testis with horizontal lie and scrotal edema. The issue walks through recognizing torsion despite an initial abdominal-pain complaint and arranging emergent surgical transfer.
CASE 2 — Partially Treated Epididymo-orchitis:
A 40-year-old man develops urethritis and a dull scrotal ache after a high-risk sexual encounter, declines empiric ceftriaxone, and returns a week later with continued testicular pain. The issue explores how enteric organisms and incomplete STI treatment can drive persistent epididymo-orchitis.
CASE 3 — Testicular Cancer Presenting as Low Back Pain:
A 52-year-old former coal miner with a history of bilateral orchiopexy for cryptorchidism presents with low back pain, breast swelling, and scrotal heaviness he attributes to aging. The issue reviews why cryptorchidism history and gynecomastia should raise suspicion for testicular cancer.

Risk Management Pitfalls
- Not performing a urogenital examination because the patient reported his pain as abdominal
- Discharging a patient home after manual detorsion improved his pain without arranging definitive surgical exploration and bilateral orchiopexy
- Using age alone, rather than the patient’s sexual practices and exposures, to select empiric antimicrobial therapy for epididymo-orchitis
- Treating only the patient’s acute concern without providing education on prevention, such as use of an athletic protector or testicular self-examination
- Assuming one testicle being larger than the other is normal without evaluating for a varicocele or testicular mass
