Abstract
RATIONALE: Segmental testicular infarction (STI) is a rare urologic disease with low incidence and rarely reported clinically; its clinical manifestations are complex and easily confused with other testicular diseases, leading to diagnostic difficulties. We reviewed a patient with unilateral STI and present the following report. PATIENT CONCERNS: The patient presented to the hospital with sudden right scrotal pain for 14 hours. DIAGNOSES: Segmental testicular infarction. INTERVENTIONS: The patient was diagnosed with STI. We gave the patient a subcutaneous injection of low-molecular-weight heparin and anti-inflammatory treatment. OUTCOMES: After 4 days of treatment, the testicular pain had subsided. When the patient was reevaluated 2 weeks later, his pain symptoms had subsided completely, and a scrotal color Doppler ultrasonography revealed that the right testicle had returned to normal. LESSONS: Early diagnosis and timely treatment are crucial for improving prognosis. Color Doppler ultrasound is an effective tool for initial screening of testicular blood flow. For patients with testicular infarction, we should perform individualized treatment to preserve testicular function as much as possible.
