Presentation as a novelty of the application of endoscopic methods in the display of the renal artery (angioscopy). Review of findings seen in the renal artery of a donor corpse with polytraumatism using direct view with a MiniScope-type rigid urethroscopy and the possible future application of this technique.
We report on a 72-year-old male patient with fibrous ureteral polyp which had been diagnosed following the incidental finding of a ureteral filling defect on radiographic evaluation for prostatism and gross intermittent hematuria of several months. We underscore the low frequency of this disorder and the therapeutic implications of differential diagnosis to distinguish this condition from other causes of ureteral filling defects.
We make an evaluation of 66 ureteroscopies (URS) carried out in our Service over a period of 18 months. In 55 cases it was done for therapeutic purposes in ureteral lithiasis, and in 11 cases it was for diagnostic purposes. In the treatment of lithiasis resolutive effectivity at the first attempt was 68%, in 9% ureterolithotomy had to be performed due to the impossibility of approaching the calculus, and in 23% supplementary treatment was carried out by means of external litrotripsy. In the diagnostic field, effectivity was 72%. Notable complications arose in 6 cases (9%), 6 ureteral perforations, in three of which a urinoma was formed, all settled with a double J catheter. Open surgery was not resorted to in any case. No sequelae were observed and this technique therefore showed itself to be safe and effective.
A case is described of a urethral foreign body of long evolution, introduced for masturbatory purposes and which had its clinical origins as a periurethral abscess. We comment on the diagnostic steps and the therapeutic attitude followed.

Increased production of prolactin by the pituitary is a factor to be taken into account as a cause of peneal erectile dysfunction (PED), which varies depending on the series from 1 to 16%. 1,2,7 We contribute in this paper one patient with infertility and erectile dysfunction secondary to a prolactin-producing pituitary tumour, prolactin plasma levels returning to normal after treatment with bromocriptine, which also achieved a remission of the clinical picture.
