Low‐flow priapism: risk factors for erectile dysfunction

摘要: Objective To evaluate our policy of managing priapism for the success rate treatments, potency afterward, complications, and risk factors responsible erectile dysfunction in these patients. Patients methods The study included 50 patients (mean age 37.1 years, range 22–66) with a diagnosis (1981–1999). Their records were reviewed; 35 available long-term evaluation. Factors assessed duration priapism, history previous recurrent attacks, possible underlying causes (e.g. haematological disorders, medications or trauma), relation to sexual stimulation, pain, any attempt at management. A complete blood screen gases corporal aspirates. Duplex ultrasonography was used all impotent their follow-up. Early late complications reviewed, asked about function before recurrence. Results median (range) 48 (6–240) h; almost half presented > 48 h after onset priapism. Sixteen (32%) reported whom seven had treatments. main cause idiopathic intracavernosal injection papaverine. All initially treated by aspiration ephedrine; if this failed prolonged (> 48 h) various shunts used. hospital stay significantly shorter among papaverine-induced brief In follow-up 66.4 months, 3–220) only 15 (43%) preserved function, more likely (  48 h) from other than 20 men evaluated Doppler severe echo-dense penile fibrosis high end-diastolic velocities suggesting veno-occlusive incompetence except two. five cavernosography showed extensive venous leakage irrespective site shunt. MRI heterogeneous areas low signal intensity, corresponding haemosiderin deposition fibrosis. On univariate analysis final result management (complete detumescence not), presence influenced function. multivariate logistic regression first remained significant. Conclusions Low-flow > 48 h, failure maintain management, marked during are most significant dysfunction, achieve detrimental.
