Appendicitis and low-flow priapism in children.

Priapism is a sustained erection that is maintained for over 4 hours in the absence of sexual stimulation [Postgrad Med J. 2006;82(964):89-94; J Urol. 2003;170:1318-1324]. Distinction is made between low- and high-flow variants [J Urol. 2003;170:1318-1324; Cardiovasc Intervent Radiol. 2002;25(4):326-329]. Low-flow priapism (LFP) and acute appendicitis are rarely associated. Including ours, there are 4 cases reported in the literature, all of which have occurred in children. The complications of LFP are potentially serious and include loss of the phallus altogether. Treatment of LFP is should be prompt and is the same irrespective of the etiology.
