A foreign body retained in the urinary bladder can provide a nidus for stone formation. Trichobezoar is a rare condition whereby a hairball is found in the human stomach or gastrointestinal tract. Trichobezoar cases have been reported in the urinary bladder and represent a rare complication of foreign bodies, called ‘‘hair nidus or hairball,’’ in patients with chronic catheterization.
Here we report a 56-year-old male patient with paraplegia and a long-term indwelling catheter in neurogenic bladder presented with repeat catheter falling out. Chronic catheter was related to thoracic spinal cord dysfunction after the patient undergoing emergent hemiarch replacement due to DeBakey type I aortic dissection 6 years previously. Cystoscopy revealed many small stones caused by hair encrusted together. The stone-coating hairball was smoothly extracted with the aid of cytolithotripsy.
