The Winter procedure as management for prolonged low-flow priapism: a case report.

Priapism is a prolonged penile erection that is not associated with sexual stimulation. Although the time course has not been formally defined, it is usually considered to be one that lasts for more than 4-6 hours. Low-flow (ischemic) priapism is usually associated with sickle cell disease, hemoglobinopathies, neoplastic syndrome, anticoagulant therapy, psychotropic medication or idiopathic causes.

Retrocaval ureter: report of two cases and literature review.

Retrocaval ureter is a rare congenital anomaly in which the ureter passes behind, and is compressed by, the inferior vena cava. Its etiology is assumed to be abnormal embryologic development of the inferior vena cava as a result of atrophy failure of the right subcardinal vein in the lumbar portion. We report two cases of retrocaval ureter and review the relevant literature.
