ABSTRACT

Cavernous blood gas analysis in the diagnosis of priapism

The significance of blood gas analysis in the rapid and accurate diagnosis of priapism, enabling the distinction between low-flow and high-flow types deserves to be highlighted. It is a valuable tool in the clinical setting to guide timely intervention, especially in emergencies, and enhance patient outcomes, thereby reducing the risk of complications such as erectile dysfunction and penile fibrosis. We present a case of a 69-year-old male patient who developed priapism. Cavernosal blood gas analysis provided conclusive evidence of low-flow priapism, confirming veno-occlusive pathophysiology based on abnormal pH, pO2 and pCO2 values. The patient underwent venous blood aspiration from the corpora cavernosa, leading to complete penile detumescence and rapid resolution of the priapism. Laboratory medicine, through the analysis of cavernous blood gases, plays a pivotal role in accelerating the diagnostic path and the clinical management of priapism.
