A Calcified Foreign Body in the Bladder due to a Displaced Tack: An Unusual Complication After Laparoscopic Incisional Hernia Repair

We report a rare complication caused by a displaced tack after laparoscopic incisional hernia repair. A 41-year-old woman treated 11 months earlier for a suprapubic incisional hernia (Pfannenstiel laparotomy) received a laparoscopic repair with a bilaminar mesh fixed with tacks. Seven months later, she presented miccional irritative symptoms and chronic lower abdominal pain. Leucocyturia and microhematuria were present, and computerized tomography showed 2 calcified nodules in the bladder wall. Cystoscopy confirmed 2 calcified foreign bodies in the bladder due the tack fixation. She underwent an intra-abdominal laparoscopic exploration, which showed the protrusion of a mesh in the urinary bladder. The tacks were removed and a partial laparoscopic cystectomy including mesh protrusion was performed. The patient was discharged from hospital 4 days later without postoperative complications. At follow-up 24 months after surgery, she remains well with no pain, urinary symptoms, or hernia recurrence.
