Small renal tumors are increasingly diagnosed and are frequently treated by nephron-sparing surgery. Tumors can be ablated by radiofrequency (RF) energy, which allows the operator to create very localized necrotic lesions. Radiofrequency interstitial tumor ablation (RITA) has been used in human kidneys in an ex vivo experiment to assess the necrotic lesions(More)
Since the advent of reversible androgen deprivation, its use for a short period of time (usually 3 months) before radical prostatectomy has been advocated by an increasing number of urologists without clear and definitive proof of its advantage. Most authors have demonstrated downsizing of the prostate by some 30-50%. Clinical downstaging was demonstrated(More)
PURPOSE With the arrival of new oral therapies the question arises about the role of surgery in patients with vascular impotence. We compared the sexual satisfaction rate in patients with arterial and/or venous impotence treated with 4 surgical techniques with long-term followup. MATERIALS AND METHODS Surgery was performed in 130 patients with vascular(More)
After mastectomy and radiation for breast cancer, two patients were found to have persistent elevated CEA in their serum. This finding was erroneously attributed to occult metastases for the first patient and to local recurrence for the second. Overlooked medullary thyroid carcinoma (MTC) was the causal disease in both patients. A review of the literature(More)
Urolithiasis has an incidence of about 12% in men and about 5% in women before the age of 70 years. Several epidemiological factors are involved in the predisposition to the urinary stone disease, notably: age, sex, race, climate, geography, profession, social class, nutritional factors and inherent genetic particularities. A number of physicochemical(More)
Great interest has been generated recently in preoperative androgen deprivation for clinical stage B ou C (T2 ou T3) prostate cancer. The influence of neoadjuvant hormonal therapy on down-staging and down-grading is still controversial. To assess the influence of preoperative androgen deprivation on serum PSA levels, we compared pre- and post-treatment(More)
Metabolic evaluation remains cornerstones in the treatment and prevention of recurrence in patients with urolithiasis. The various chrystallographic, biological and radiological investigation should be done only in patients presenting recurrence and/or given risks factor of recurrences. The choice of the investigation is guided by the knowledge of the(More)
Diagnosis of the stone is based on anamnesis, physical examination and radiological investigation. Anamnesis and physical examination need to be supported by knowledge of the neuroanatomy of the urinary upper tract. Radiological investigation should be both non toxic and effective. Gold standard radiological examination in the evolution of urolithiasis(More)
