title: [Low-flow priapism associated with systemic lupus erythematosus and nephrotic syndrome].
abstract: OBJECTIVE
  To present a case of priapism associated with systemic lupus erythematosus and nephrotic syndrome.
  
  
  METHODS
  A 29-year-old male patient with a history of multiple pathologies consulted at the emergency services with painful priapism of 12 hours' duration. The intracavernosal aspirated blood had a venous appearance. Among the risk factors analyzed, systemic lupus erythematosus and nephrotic syndrome are recognized to cause hypercoagulability, a condition that can lead to low flow priapism.
  
  
  RESULTS
  There was no response to lavage-aspiration or intracorporeal administration of an alpha-adrenergic agonist. The high surgical risk of the patient advised against surgery. The priapism gradually diminished until complete remission on the sixth day. The patient has remained without spontaneous erection.
  
  
  CONCLUSIONS
  Systemic lupus erythematosus and nephrotic syndrome can cause low flow priapism. The best treatment is by prevention with adequate antithrombotic prophylaxis.
