SUMMARYAn 86-year-old woman underwent routine catheter replacement in the community. The new catheter failed to drain urine. Attempts to remove the catheter failed, both by the community nurse as well as by the urology team in the hospital. A CT scan confirmed that the catheter balloon was inflated in the distal right ureter. The patient was started on antibiotics and listed for cystoscopy under general anaesthetic. The catheter was visualised entering the right ureter and the balloon punctured using a wire under image intensifier guidance. Once removed, a new catheter was inserted. Very dilated ureteric orifices were noted. Post operatively the patient required HDU support for 48 h due to sepsis and on recovery was discharged home. The key learning point in this case is to always consider catheter misplacement in the ureter if it is not draining well and the patient presents with pain.
