About this study

The etiology of the radiation cystitis is a pelvic irradiation generally performed as part of the treatment of prostate cancer. The incidence is 50,000 new cases per year. Approximately 35% of prostate cancer treatment is radiotherapy. The prevalence of haematuric radiation cystitis is 4-5% (about 800 patients). One of the complications of radiation cystitis is persistent hematuria. There is currently no curative treatment for this hematuria. There are few treatment options with a random probability of improvement of this symptomatology. These haematurias are rarely resolved spontaneously and most of the time involve emergency room management with +/- invasive procedures, sometimes by hospitalisation, always with a significant psychological impact on the patient. Furthermore, lifetime anticoagulant treatment considerably increases the likelihood of bladder bleeding. This is the case of patients being followed for Atrial Fibrillation Cardiac Arrhythmia (AFCA), which by definition carries a major cardioembolic risk, and who will be of particular interest in this study. In recent years, cardiologists have developed an alternative to anticoagulants: left atrial appendage closure or left atrial occlusion (LAO) . This procedure consists of inserting a nitinol prosthesis in the left atrium, the site of more than 90% of thrombi formation in non-valvular atrial fibrillation. This minimally invasive procedure lasts about 15 minutes and is performed during a 48-hour hospitalization. …
