The level of obstruction was severe in 13 patients(More)
STUDY AIM Assessment of laparoscopic adrenalectomy in the management of operable non-small cell lung cancer (NSCLC) associated with solitary and synchronous adrenal mass. PATIENTS AND METHODS In a retrospective study, we reviewed 3 patients with operable NSCLC proved by pulmonary biopsy and an isolated synchronous adrenal mass shown by abdominal CT scan.(More)
OBJECTIVE To evaluate the functional and cancer results of radical prostatectomy with bladder neck preservation in the treatment of localized prostate cancer. MATERIAL AND METHOD From January 2000 to March 2006, 194 consecutive patients underwent open retropubic radical prostatectomy for localized prostate cancer. The bladder neck was technically(More)
OBJECTIVE This retrospective study evaluated the prognostic value of the initial or secondary status of pT1G3 bladder tumours. MATERIALS AND METHODS Between 1990 and 2000, 93 patients presented with T1G3 bladder tumour. Seventy-five patients, 54 with initial T1G3 and 21 with secondary T1G3, with no history of invasive bladder tumour, were included in the(More)
Flexible ureteroscopy combined with Holmium-YAG laser is an effective, reproducible and minimally traumatic diagnostic and therapeutic technique perfectly adapted to diseases of the upper urinary tract. This technology must be part of the therapeutic armamentarium of any centre involved in the management of urinary stones. The technical facilities must be(More)
Flexible ureterorenoscopy combined with Holmium-YAG laser is an effective and reliable technique for the management of renal stones. Cacchi-Ricci disease is a frequent urological malformation characterized by precalyceal stone formation, for which no preventive treatment is available at the present time. Some complicated forms are difficult to manage(More)
In 1980, Christol, Kamae, Mendès France and Rauzy stated in [3] an important theorem in automata theory. This theorem links sequences recognized by automata and algebraic formal power series. In 1994, Bruyère, Hansel, Michaux and Villemaire extended this theorem with a logical link in [2]. With theses two articles, we can translate the property for a formal(More)
