We present an 85-year-old male patient with persistent irritative symptoms and recurrent bladder stones after being treated twice with cystolitholapaxy. The patient had a history of left inguinal hernia, repaired 24 years ago. The provisional diagnosis was recurrent stones due to a bladder outlet obstruction, and imaging revealed possible stones inside a bladder diverticulum. We did not expect the stones to be a complication of synthetic mesh, and eventually the stones failed to be crushed by mechanical lithotriptor. The patient was explored, the stones were removed, and we found the mesh penetrating the left wall of urinary bladder (UB) with dense adhesion to the left pelvic wall. For a radical cure, the mesh with part of the UB wall had to be removed and repaired, but in view of this unexpected event, the patient required general after spinal anesthesia. The postoperative procedure passed uneventfully.
