Bladder lithiasis on tension-free polypropylene tape after TVT technique

We describe a case of a 74-year-old woman with a history of hysterectomy and subsequent placement of tension-free tape, according to TVT procedure, who presented with bladder lithiasis secondary to bladder perforation after placement of the aforementioned tape. The treatment included endoscopic lithotripsy for lithiasis removal and resection of distal and proximal ends of intra-bladder tape with the aid of endoscopic scissors, and photocoagulation of the resulting carved lesions with Holmium:Yag laser. The composition of lithiasis was magnesium ammonium phosphate with some calcium phosphate 1 month later, the patient feels asymptomatic; cystoscopy reveals complete restitution of bladder mucosa and absence of intra-bladder protrusion of the aforementioned material.
