[Renal arteriovenous fistula, up-date and presentation of a new case]. / Fístulas arteriovenosas renales, actualizacíon y presentación de un nuevo caso.

Renal arteriovenous fistulae (AVF) conform a pathology the urologist is not used to see. The basic purpose of this paper is to collect and update the current knowledge of this renal-vascular disorder, quite frequently forgotten when establishing the likely causes of haematuria. The paper describes the etiology of renal AVF and their generation mechanisms, as well as clinical presentations they can have. A most appropriate diagnostic method is still selective renal arteriography, which usually evidences the anomaly through indirect arteriographic signs. However, when the lesion is small it can be difficult to detect it. Finally, a discussion of therapeutical possibilities, both conservative and radical, and a case recently treated in out unit are presented.

[Ectopic ureter in seminal vesicle with cystic dysplasia. A clinical case and review of the literature]. / Uretér ectópico en vesícula seminal con displasia quística. Caso clínico y revisión de la literatura.

A new case of ureter ectopic abouchement in seminal vesicle with cystic dysplasia is presented in one asymptomatic male attending the clinic on an infertility consultation. Suspected diagnosis was based on right kidney absence observed on abdominal echography, associated to severe oligoastenozoospermia seminograms and decrease in ejaculation volume. The computerized axial tomography revealed changes of the ipsilateral seminal vesicle. Diagnosis was confirmed by deferentovesicullography. Malformation embryological and anatomical aspects, as well as accompanying ipsilateral kidney dysplasia are commented. A review of both national and international literature is made supporting the unusual character of the clinical case presented.
