New combined approach in metallic ureteral stenting to avoid urothelial hyperplasia: study in swine model.

Purpose: We assessed the therapeutic value of a new treatment option for ureteral strictures that may avoid urothelial hyperplasia, which is the main cause of metallic stent failure.

Materials And Methods: We used 24 pigs in this study. An experimental model of ureteral stricture was induced in all animals.

Association of steroid and xenobiotic receptor (SXR) and multidrug resistance 1 (MDR1) gene expression with survival among patients with invasive bladder carcinoma.

Unlabelled: What's known on the subject? and What does the study add? SXR and MDR1 are known as responsible for chemo and radiotherapy resistance in some cancers, like kidney cancer (MDR1). Invasive bladder cancer is an aggressive disease, with different behaviour upon its tumoral stage, and also within the same tumoral stage, therefore molecular markers are sought. This study shows a new molecular marker, which has shown as a predictor for bad prognosis cancers, therefore, allowing us for a better patient selection for aggressive therapies.

Ureteral double-J wire stent effectiveness after endopyelotomy: an animal model study.

Objectives: The aim of this experimental study was to assess the possibility of decreasing the size of the ureteral stents used after an endopyelotomy. To this end, an experimental study was performed which compared a ureteral double-J wire stent versus a standard 7F ureteral stent after endopyelotomy.

Methods: Twenty healthy female pigs were randomly divided into 2 groups: group I (double pigtail ureteral stent 7F) and group II (lumenless ureteral double-J wire stent, Zebrastent™, 0.

Atypical small acinar proliferation: review of a series of 64 patients.

Objective: To study the evolution of 64 patients initially diagnosed with ASAP (atypical small acinar proliferation).

Material And Methods: Between 1998 and the end of 2003, 64 patients were diagnosed at our centre with ASAP.

Results: The mean age of the patients assessed was 69 years (SD 6.

[The treatment of metastasic testicular pure mature teratoma].

Objective: Given the low frequency of testicular teratoma in relation to the rest of germ cell testicular tumors and the various treatment options for advanced stages, we report one case of advanced testicular mature teratoma with retroperitoneal adenopathy in which orchyectomy was performed after retroperitoneal lymphadenectomy, with the some pathology found in the primary tumor.

Methods: We do an update on the treatment for these stages with the possibility of beginning with chemotherapy leaving lymphadenectomy for residual masses, or the contrary, being most cases treated in a mixed way.

Conclusions: Without clear evidence for guidelines in these tumors, it is recommended to individualize the treatment for each patient, accordingly to tumor characteristics, probability of relapse and follow-up.

Epidermal naevus syndrome (Solomon's syndrome) associated with bladder cancer in a 20-year-old female.

Epidermal naevus syndrome was first described by Solomon et al. in 1968, based on a study of 12 patients. Herein we report the case of a 20-year-old female diagnosed with epidermal naevus syndrome at the age of 3 years.

Malignant mesothelioma of the tunica vaginalis. Report of a case without risk factors and review of the literature.

Malignant mesothelioma of the tunica vaginalis testis is an aggressive tumour with local recurrence being distant metastases the main feature of the clinical course. Usually appears over the fourth decade, having a strong relationship with occupational exposure to asbestos and long lasting hydrocele. We introduce a case of a 78-year-old caucasian male who developed a malignant mesothelioma without personal history of hydrocele or exposure to asbestos.
