An Unusual Case of Bladder Wall Erosion Due to Prolonged Use of a Coudé Tip Urethral Catheter in a 79-Year-Old Man.

We present the case of a 79-year-old man with long-term lower urinary tract obstruction managed with a coudé tip urethral catheter, who had an incidental finding of posterior bladder wall erosion diagnosed at cystoscopy for prostate enucleation. The posterior bladder wall erosion was treated conservatively. This rare but serious complication highlights the potential risk of prolonged use of rigid, curved-tip catheters and the need for careful catheter selection and regular reassessment in patients requiring long-term indwelling urinary drainage.
