Abstract:
Erosion of metal surgical staples is a rare but described surgical complication. Staple erosion in a bladder may present with hematuria, urinary tract infection (UTI), bladder pain, or fistula. We present a 64-year-old male with a history of urothelial carcinoma treated by cystoprostatectomy with neobladder reconstruction. Over the next two to three years, he developed hematuria and had multiple urine cytologies suspicious for cancer. The cystoscopic evaluation revealed staple line erosion but no cancer. We believe this to be the first published case of symptomatic staple erosion in a neobladder. Clinicians should be aware that staple line erosion in a neobladder can occur and mimic malignancy recurrence.
