Sub-urethral support techniques using synthetic sling are the current gold standard in the treatment of stress urinary incontinence. We report the case of a 60-year-old female patient with a personal history of stress urinary incontinence treated with suburethral TVT sling in 2008. Intraoperative cystoscopy was normal. Six years later the patient had recurrent urinary tract infections caused by Escherichia Coli, resistant to all appropriate antibiotics. The patient underwent ultrasound which objectified intravesical stone measuring 2.5 cm on the major axis; post-void residual urine volume was zero. Fibroscopy showed intravesical sling surrounded by a large calcification. Our patient underwent conservative treatment, which consisted of endoscopic section of the intravesical portion of the sling with preservation of the sub-urethral portion. The calculi was fragmented using Lithoclast. Functionally, our patientis is continent.
