[High flow arterial priapism secondary to post-traumatic bilateral arterio-cavernous fistula. Highly selective embolization with autologous blood clot].
High flow arterial priapism is rare and characterized to a prolonged non-painful partial erection. Arteriocavernous fistula, rarely bilateral, is associated with penile or perineal trauma (genitoperineal area). Review of the literature, in only eleven cases this fistula is bilateral. Different treatments with non common norm has been used. We report a case of a 27 years old male who presented high flow priapism secondary to bilateral postraumatic arterio-cavernous fistula. Autologous blood clot was used for fistulas embolization to minimize the risk of impotence in this young patient. No complications was registered. Eight months later the patient had normal erectile function and no fistula was detected on ultrasonography doppler. We consider arteriography with highly selective embolization using re-absorbable agents obtains the best results, the least risks and complications in this process.

[Traumatic urethral disruption in women. A rare entity. Report of two cases].
We present two cases of urethral disruption in women, a very uncommon situation because of the anatomical features. Yet it must be always suspected in all women under a pelvic politraumatism, for eviting important problems. Both cases are traffic politraumatized young girls presenting with pelvic fracture, among others. The surgery performed was combined suprapubic-transvaginal approach, even in one a previous endoscopic realinement was done, who also needed endoscopic complementary treatment: electrofulguration of a fistulous bridge. Outcome of both is fine, achieving good continence. We also make a literature review.

[Bladder choriocarcinoma: retrospective analysis of the de-differentiation of a transitional-cell papillary bladder carcinoma. Apropos of a case].
OBJECTIVE: To report a case of choriocarcinoma of the bladder during the different periods of its evolution. The anatomopathological study showing dedifferentiation of a transitional cell tumor is presented and the histogenesis of this rare tumor is discussed. METHODS: A case of a rapidly progressing transitional cell tumor of the bladder that dedifferentiated into choriocarcinoma is presented. The pathological findings of the first resections of the transitional cell tumor that progressed to choriocarcinoma are presented and the histogenesis is discussed. RESULTS/CONCLUSIONS: Choriocarcinoma of the bladder is very rare, highly malignant and carries a poor prognosis. Its origin is widely accepted to be in the dedifferentiation of a transitional cell tumor. The use of immunohistochemistry and the positivity of HCG support the diagnosis.

[Asymptomatic bladder paraganglioma. Report of a case].
Paragangliomas are tumors which arise from collections of neuroepithelial cells (paraganglion system) scattered throughout the body and rarely in the urinary bladder. In this work, we described a case of bladder paraganglioma, not suspected in a 64-year-old male who showed occasional total hematuria as only symptom. Cystoscopically, it was diagnosed as a rounded, not papillary tumor, one centimeter in diameter on account of which it was subjected to TUR. Confirmed the diagnosis, a partial cystectomy and a limited regional lymphadenectomy were subsequently practised. Posterior evolution, after a year, was completely favourable. The main clinicopathologic characteristics of this entity are revised.
