Urological emergencies are diseases with an unpredictable but worsening trend. Since some of them potentially life-threatening, they require urgent treatment. In urology, the emergencies are urinary obstruction, obstructive pyelonephritis, gross hematuria with clot retention, priapism, penile fracture, Fournier's gangrene, Testicular torsion, and paraphimosis.

Testicular torsion is one of the leading causes of acute testicular pain in pubertal age. Waiting too long for diagnosis and treatment might cause loss of the testis that has to be removed because of irreversible necrosis.
