[The therapeutic dilemma of the early invasive bladder cancer]. / Le dilemme thérapeutique du stade micro-invasif du cancer de la vessie.

Transitional tumours of the bladder are classically divided in superficial (lesions of the mucosa and the submucosa) and invasive (infiltrating the detrusor) cancers. However, the recurrence and progression rate of submucosal urothelial cancers is highly variable. Therefore, management of such neoplasias is very challenging, some patients requiring a cystectomy, whereas others can be managed less invasively with endoscopic resection eventually associated with intravesical chemotherapy. We review herein the prognostic factors which help us to orientate our patients. We also emphasize the importance of the subclassification of the micro-invasive stage, and its practicability, which is reliable and simple, as opposed to the general belief.

[Treatment of symptomatic prostatic hypertrophy with the KTP-80 laser]. / Traitement de l'hypertrophie symptomatique de la prostate par le laser KTP-80.

Macroscopic per and post-operative hematuria contributes significantly to hospitalisation time and to the morbidity of conventional surgery of symptomatic prostatic hypertrophy. It requires in fact transient anti-coagulation interruption, so as eventually a window with platelet anti-agregants. The newly available 80-Watts Potassium-Titanyl-Phosphate laser markedly reduces post-operative hematuria, and allows operating the increasing population of patients under platelet anti-agregants, or event those who need therapeutic anticoagulation. This series reports on our initial experience with a technique which decreases remarkably post-operative catheterization and hospitalisation time, and whose obstruction relief is efficient, but needs to stand the test of time.
