[Follow-up of the FlowSecure artificial urinary sphincter].

The AMS-800 artificial urinary sphincter has been the only prosthesis available for treatment of stress urinary incontinence refractory to other therapeutic modalities for the past 25 years. The relatively high rate of complications occurring with the AMS-800 device during this time led to introduce a number of changes in its design that resulted in a new prostheses, the FlowSecure artificial sphincter. The FlowSecure artificial urinary sphincter is an adjustable prosthesis filled with normal saline without contrast.

[Antibiotic prophylaxis in transrectal prostate biopsy].

Introduction: Transrectal ultrasound-guided needle biopsy of the prostate is a safe technique, but it is not complication-free, and its most serious complications are genitourinary infections (GUI) and the conditions they cause. The purpose of antibiotic prophylaxis is to reduce this GUI incidence rate. However, no established guidelines exist and there are significant differences among centres where this procedure is performed.

Surgical implantation of the new FlowSecure artificial urinary sphincter in the female bladder neck.

Objective: To report implantation of the new FlowSecure artificial urinary sphincter with conditional occlusion in a female bladder neck, describe surgical technique and suggest minor modifications to accommodate the device for universal female implantation.

Patient And Methods: A spina bifida female patient with urodynamically proven stress incontinence due to sphincteric incompetence associated to atonic detrusor was implanted with the new artificial sphincter. Operating time was one and a half hours.

[Papillary and cavitary monohydrate calcium oxalate lithiasis: comparative study of etiological factors].

Objectives: The monohydrate calcium oxalate lithiasis (MCO) is divided in two groups depending on the morphologic-crystal structure: papillary (anchorage point on a renal papilla lesion) and cavity (formed in a cavity with low urodynamic capacity). The minimal differences between urinary biochemistry of MCO makers in comparison with healthy population suggests that other factors different than urine biochemistry (professional activity, dietetic habits, systemic diseases) may be related with lithogenesis. The objective of this work is to study such factors, and compare them in both groups of MCO lithiasis (papillary and cavity).
