| Summary points: | A 63-year-old spinal cord injury patient with a nonfunctioning Brindley sacral anterior-root stimulator presents with a continually blocking urethral catheter. This case report details the patient's history, findings from cystoscopy and electrohydraulic lithotripsy, biopsies, computed tomography, and histological studies, and treatment outcome, and includes some images. The authors discuss the likely factors which decrease the risk of vesical malignancy in patients with a satisfactorily functioning stimulator. |
