RESUMO
INTRODUCTION: The aim of this study is to evaluate the percentage of patients developing vesical overactivity after the realization of a continent stoma without bladder enlargement. MATERIAL AND METHOD: This is a retrospective monocentric study between January 2007 and April 2021. Patients undergoing an isolated continent urinary diversion for neurological or non-neurological reasons were included. The data collected concerned the clinical symptoms of bladder overactivity and their treatment as well as the pre- and postoperative urodynamic information. RESULTS: During the period, 9 patients were included. The main indications for continent urinary diversion were patients with spinal cord injury. Clinical bladder overactivity was found postoperatively in 78% (7) of the patients, and detrusor overactivity in 57% (4) of them. The main symptoms were urinary incontinence (67%) and pollakiuria (56%, 5 patients). Most of the patients benefited from associated treatments (78% pre- and postoperative), mainly anticholinergic drugs. No patient required botulinum toxin injections preoperatively, compared with 6 (67%) postoperatively. The time of initiation of these injections varied between 3 and 8 months postoperatively. CONCLUSION: Isolated continent urinary diversion seems to induce or increase bladder overactivity. A larger multicentric study is necessary to validate our hypothesis.
