Giant stercoral stone and catheterization difficulty.
An unusual case of giant calcification in the midline of the pelvis is reported herein. An 84-year-old male, whose urination was managed by clean intermittent self-catheterization (CIC), presented with catheter insertion difficulty. The patient had a history of transurethral operations for benign prostatic hyperplasia and small bladder stones. Kidney, ureter and bladder (KUB) X-ray of post-enhanced computed tomography (CT) suggested a giant ball-shaped calcification in the bladder. A recurrent bladder stone was suspected. However, pelvic CT scan revealed that the giant calcification was, in fact, situated in the rectum. Thus, a diagnosis of giant stercoral stone was made. After the stone was removed manually, the patient had no difficulty in inserting the catheter. His prior complaint may have been caused by urethral bladder neck obstruction due to the giant stercoral stone.
