Piesis Sign Distinguishing Non-Ischemic Priapism in a Child

To differentiate between non-ischemic and ischemic priapism is imperative in clinical settings because the treatment of these two conditions is different and urgency of treatment too. Patient’s history and Doppler color flow ultrasound contribute to the diagnosis. However, in situations where radiological investigations are not readily available in odd hours, a clinical test described in this report, the Piesis test, may be convenient. We herein report a 10-year-old boy with non-ischemic priapism diagnosed successfully with Piesis test.
