The pediatric acute scrotum.

The pediatric acute scrotum can be a diagnostic dilemma. The history, physical examination, and appropriate tests are important. The correct diagnosis will be arrived at if the systematic approach is remembered (Figure 14). In cases where testicular torsion cannot be ruled out (such as an epididymitis or torsion of the appendix testis where torsion of the testis is mimicked), the patient will need scrotal exploration. It is hoped that with further availability of scanning and expertise by pediatric surgeons the false negative exploration will decrease in number. Remember, occasionally a patient will require scrotal exploration with biopsy of the epididymis to delineate the underlying cause. In most cases of epididymitis, effort should be made to identify the cause by culture of urine, urethral discharge, or appropriate fluid from the epididymis. Urological evaluation will be necessary in the younger boys, particularly those with recurrent episodes, to rule out congenital anomalies. Only by following this systematic approach can clinicians hope to preserve gonadal function and achieve best care of their patients.
