[Bladder leiomyosarcoma in a young man with a transplant. Report of a case]. / Leiomiosarcoma vesical en joven trasplantado. Aportación de un caso.

Contribution of one case of a 24-year-old patient, with a renal graft, who was diagnosed with vesical leyomiosarcoma. Radical cystectomy with ureterosygmoidostomy was performed.

[Bladder paraganglioma. Report of a case and review of the Spanish literature]. / Paraganglioma vesical. Presentación de un caso y revisión de la literatura española.

Paragangliomas are rare tumours of the bladder accounting for 0.06% of all vesical tumours. This paper reports one case of vesical paraganglioma in a young female patient that has the singularity of being associated to melanin pigmentation.

[Ureteroscopy with pseudoanalgesia in the treatment of ureteral lithiasis]. / La ureteroscopia con sedoanalgesia en el tratamiento de la litiasis ureteral.

Presentation of the results obtained in 35 patients with ureteral lithiasis treated over a two-year interval by means of ureteroscopy with pseudoanalgesia at the Hospital Insular, with a 89% success rate. We conclude that in selected cases, the use of peg ureteroscopy or pneumatic lithotrite is a valid therapeutical option since it is well-tolerated and has the benefit of a short or null hospitalization.

[Wunderlich's syndrome as the first manifestation of a renal angiomyolipoma]. / Síndrome de Wunderlich como primera manifestación de un angiomiolipoma renal.

OBJECTIVES: We present a case of renal angiomyolipoma presenting as Wunderlich syndrome. METHODS: The clinical and radiological features of the spontaneous perirenal hematoma are analyzed. RESULTS: Because it is a benign tumor, treatment of renal angiomyolipoma is by conservative surgery; however, this is not always possible. CONCLUSIONS: In patients with renal angiomyolipoma, treatment by nephrectomy or conservative surgery will depend on the hemodynamic status of the patient.

[Urinary bilharziasis. Comments on 10 cases]. / Bilharziosis urinaria. Comentarios sobre 10 casos.

Urinary bilharziasis is a parasitic disease caused by Schistosome haematobium which is prevalent in several African and Middle East countries. The closeness of the Canary Islands to the African continent and a greater population mobility have allowed us to diagnose and treat ten patients, all of them natural of this region. This paper outlines the case-reports, and reviews this parasitic disease which seriously affects the urinary tract and which must be specifically contemplated both in emigrants and occasional visitors from endemic regions.

[Renal adenocarcinoma with multicystic pattern]. / Adenocarcinoma renal con patrón multiquístico.

One growth pattern of renal carcinomas is the multicystic of multilocular cysts one, of which few cases have been published but which according to Hartman represent 15% of total cases. This variant of the renal tumour arouses great diagnostic and therapeutical uncertainties with multicystic kidney, biopsy after surgery being the test which provides true diagnosis. Presentation of two clinical cases and review of this condition.
