[Gunshot bladder trauma: case report and literature review]. / Traumatismo vesical por arma de fuego: presentación de un caso y revisión de la literatura.

OBJECTIVE: To report one case of gunshot bladder trauma and to review its diagnosis and treatment in the related literature. METHODS: We report the case of a 43-year-old-male with an abdominal firearm wound and gross haematuria. Imaging diagnosis by abdominal and pelvic CT and CT-cystography. Surgical treatment. RESULTS: CT-cystography showed extraperitoneal bladder rupture. Exploratory laparotomy to evaluate for other associated injuries. Bladder wall surgical closure and ureteroneocystostomy with transvesical technique because of complete distal ureter tear. Broad spectrum antibiotherapy. Favourable progress. The patient was discharged at 14th day. CONCLUSIONS: Firearm bladder traumas are a rare entity. Surgical exploration and closure is mandatory. In haemodynamicaly stable patients, abdomen and pelvis CT and CT-cystography allow us to rule out associated injuries and to classify the bladder trauma type. Ureteral damage associated in 5-8,9%, diagnosed during surgical exploration. Broad-spectrum antibiotherapy in all patients.

[Malignant vesico-prostatic fibrous histiocytoma]. / Histiocitoma fibroso maligno vesicoprostático.

Among the adult bladder sarcomas it's extremely rare as an histological variety the malignant fibrous histiocytoma. We present a case of a 25 years old young male with bladder and prostate both affected, successfully treated with radical surgery and poliquimiotherapy. We also reviewed the bibliography about this neoplasias up to now.

[Giant retroperitoneal hemangiopericytoma]. / Hemangiopericitoma retroperitoneal gigante.

We present a new case of retroperitoneal hemangiopericytoma with the special feature of a big size tumour. Due to this feature and also to the hypervascularitation we proceeded a preoperative arterial embolization that made possible its complete removal. We did a bibliographic review showing the fundamental clinic pathologic and therapeutical basic aspects of this tumours.
