[Bladder paraganglioma. Report of a case and review of the Spanish literature].

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. A review is made of cases treated in Spain, adding some comments on the signs and symptoms presented, as well as the diagnostic and therapeutical methods used in this unusual condition.

[Bladder leiomyosarcoma in a young man with a transplant. Report of a case].

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. The rarity of vesical sarcoma, both in normal population or among those undergoing transplantation, as well as the greater tendency of transplanted patients to suffer malignant neoplasia, are emphasised.

[Ureteroscopy with pseudoanalgesia in the treatment of ureteral lithiasis].

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].

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].

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].

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.

[Enterocystoplasty in the treatment of interstitial cystitis].

OBJECTIVE: To evaluate supratrigonal cystectomy and enterocystoplasty in patients with interstitial cystitis. METHODS: We reviewed four women with interstitial cystitis with infructuos conservative treatment and performed supratrigonal cystectomy and enterocystoplasty. All the patients fulfilled the NHI criteria with increased voiding frequency by night (mean 7.3 times). In 3 cases urodynamic study was available. We used is the four patients ileon as segment for the enterocystoplasty. RESULTS: Mean postoperative follow up was 60 months. In all cases the suprapubic pain disappeared and night voiding frequency reduced (mean 2.2 times). We don't have mayor complications. One patient needs self catheterism 3 years after surgery. CONCLUSION: In patients with interstitial cystitis to be operated supratrigonal cystectomy and enterocystoplasty is the most effective method.

[Transurethral resection of ureteral tumor].

A patient with a tumor in the right pelvic ureter is described herein. Following diagnosis by ureteroscopy, the patient underwent TUR utilizing a ureteroresectoscope. No short- or long-term complications were observed. The scant number of cases in the literature and the advantages afforded by this technique (noninvasive, short duration of hospital stay, etc.) prompted us to report this case.
