ABSTRACT

Objective:To discuss the diagnostic approaches and treatment choices of low-flow priapism.Methods:35 cases of patients suffered from the low-flow priapism in our hospital from September 2010 to October 2016 were selected and diagnosed with the low-flow (ischemic) priapism by combining cavernous blood gas analysisand and color duplex ultrasonography.The priapism lasted 12 to 240 h with a mean of 72 h.31 patients of them had ever been induced by Polysaccharide Sulfate.One appeared priapism after sexual life.One appeared priapism after micturition.2 of them were not known what drug they had taken.Results:The symptoms disappeared in 5 cases as a result of using cold compress,sedation method and intracavemous lavage in hospital.But 30 cases were still priapism.Their penis were in a flaccid state after they were performed with the operation of glandular cavemosum shunting.During the 6-24 months of follow-up,31 patients developed erectile dysfunction.Among them,13 cases were light to mid erectile dysfunction,10 cases were mildly and 8 cases were the worst.Conclusion:(1) Using cavernous blood gas analysis and color duplex ultrasonography is important way to diagnose priapism.(2) Cold compress,sedation method and intracavemous lavage are the first treatments for the the low-flow priapism.If they are not the effectual cure,the operation of glandular cavemosum shunting should be performed in time.
