[Percutaneous renal biopsy with a semi-automate device].

Background: The percutaneous renal biopsy is a fundamental investigation in the diagnostic procedure for renal diseases. The introduction of the kidney localisation by real-time ultrasounds made the procedure more effective and safe. The use of semi-automated and automated biopsy devices seems to go in the same way.

[Prevention of postoperative scrotal edema].

The authors describe the technique of scrotal elevation and compression for the prevention of postoperative scrotal hematoma. This technique was used in 30 patients undergoing hydrocelectomy, spermatocelectomy or epididymectomy. There have been no untoward effects associated with this technique and this technique is applicable to a wide variety of scrotal procedures.

[Bladder hemangioma. Presentation of a case and review of the literature].

The clinical presentation, the localization, the subject's age, the therapy and the lesion's histological type recall the main features of this neoplasia.
