OBJECTIVE Mapping of transrectal ultrasonographic (TRUS) prostate biopsies is of fundamental importance for either diagnostic purposes or the management and treatment of prostate cancer, but the localization of the cores seems inaccurate. Our objective was to evaluate the capacities of an operator to plan transrectal prostate biopsies under 2-dimensional(More)
A 57-year-old woman was found to have an inferior vena cava involvement of a known sinusal angiomyolipoma incompletely resected three years beforehand. Intravascular extension into the IVC of angiomyolipoma has rarely been reported. We present a new case and reconsider the literature about this uncommon complication of a benign renal tumor.
BACKGROUND AND PURPOSE Percutaneous renal access in the context of percutaneous nephrolithotomy (PCNL) is a difficult technique, requiring rapid and precise access to a particular calix. We present a computerized system designed to improve percutaneous renal access by projecting the ultrasound puncture tract onto fluoroscopic images. MATERIALS AND METHODS(More)
AIMS To study clinical and urodynamic data along with immediate and long-term morbidity of surgical management of neurogenic bladder in spinal cord injury (SCI) patients METHODS Single-center retrospective study of 61 SCI patients with neurogenic detrusor overactivity (NDO) related urinary incontinence and/or sphincter weakness incontinence who underwent(More)
Basing themselves on 149 cases, the authors describe the spinal neurophysiology of ejaculation in spinal man, and put forward certain hypotheses. They suggest that the reflex of seminal emission is a lumbar reflex, which may be dependent on conductive factor originating in the upper neurological structures, and that the orthosympathetic system, which leaves(More)
AIMS To review the indications and to assess the functional outcomes after placement of a new temporary urethral stent (TUS) in men with lower urinary tract dysfunction. METHODS We retrospectively reviewed the data of men with prostate obstruction and concomitant high-risk surgical status or neurological diseases between 2006 and 2008. TUS placement was(More)
The purpose of this study was to assess urodynamics parameter changes induced by acute sacral neurostimulation (SNS) in spinal cord injury (SCI) patients with neurogenic detrusor hyperreflexia. Fourteen SCI patients with urge incontinence owing to a hyperreflexive bladder were prospectively evaluated. Neurostimulation was performed on the root that obtained(More)
OBJECTIVES To describe a new approach to the pudendal nerve from a dorsal direction in terms of topographic anatomy and to discuss pudendal nerve neurophysiology in light of the rationale behind pudendal nerve stimulation to treat lower urinary tract disorders. MATERIALS AND METHODS Cadavers of four women aged 78-87 yr were studied. After placing the(More)
