OBJECTIVE To evaluate our results of retrograde laser endopyelotomy for uretero-pelvic junction obstruction. MATERIAL AND METHODS Retrospective study of 27 consecutive retrograde laser endopyelotomies performed on 24 patients over a six years period (June 1999 to July 2005). Sixteen stenoses were primary. 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)
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)
INTRODUCTION Neuroendocrine cancer of the prostate (NECP) is a rare entity. Screening for this tumour, although not systematic, may have therapeutic implications. The authors retrospectively evaluated 6 cases of NECP observed in the department between September 1998 and May 2002. MATERIAL AND METHODS The diagnosis was based on immunohistochemical analysis(More)
The current management of hormone-refractory metastatic prostate cancer is purely palliative. The use of chemotherapy in this indication was revised in 1996, based on the results of studies with a combination of mitoxantrone and prednisone. This combination demonstrated a significant improvement of quality of life (+48%) and pain (+30%), but without any(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)
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)
