[Stasis priapism secondary to PGE1: transformation into high-flow priapism]. / Priapismo de éstasis secundario a PGE1: transformación en priapismo de alto flujo.

Since vasoactive agents were first introduced for the diagnosis and treatment of Erectile Dysfunction (ED), the most feared side effect has been priapism. The arrival of Prostaglandin E1 (PGE1) limited to a large extent the incidence of this complication due to its fast systemic and intracavernous metabolism. A case of stasis priapism following a low dose PGE1 injection (10 mcg) after 48 hours evolution and its surprising conversion to high flow priapism after the surgical procedures performed to solve this complication is presented here.

[Cyst of the seminal vesicle. Importance of transrectal echography in this type of malformations]. / Quiste de vesícula seminal. Importancia de la ecografía transrectal en este tipo de malformaciones.

Presentation of one case of seminal vesicle cyst with no associated anomalies. Review of diagnostic procedures useful in this type of disease, illustrating the relevance of transrectal ultrasound scanning due to its high specificity and low morbidity. Comments on the therapeutical options for this entity.

[Ectopic opening of the ureter into the ejaculatory duct. Use of ultrasound-directed vesiculography in the diagnosis of this type of malformation]. / Desembocadura ectópica de uréter a conducto eyaculador. Utilidad de la vesiculografía directa ecodirigida en el diagnóstico de este tipo de malformaciones.

We report a right mesonephric duct malformation consisting of an ectopic ureter opening into the ejaculatory duct, ipsilateral renal agenesia, ipsilateral seminal vesicle cyst, and contralateral renal malrotation. The diagnostic methods considered useful in this condition are described, including direct ultrasound-guided vesiculography, a technique which, in our experience, is easy to perform and has proved to be very useful.
