not sure if a tube injection/change (76080/49424/75984/49423) would be best for this or 51705/51710 with a mod? TECHNIQUE: Following informed consent, and verification of the correct patient identity and planned procedure, the anterior lower abdomen, including the indwelling suprapubic drain, was prepped and sterilely draped. Local anesthesia around the drain was administered using 2% Lidocaine. Contrast was injected through the tube and spot film imaging was performed as a baseline cystogram. Review the images failed to identify the bladder. A small tract was identified from the subcutaneous pocket in which the catheter was positioned, which extended toward the region bladder. Over wire the catheter was exchanged for 5-French Berenstein catheter. Additional contrast was injected in attempts at defining a tract to the bladder, but ultimately to no avail. Therefore, over wire a new 10-French MPD drain was introduced into the subcutaneous cavity. The tube was sutured to the skin and placed to gravity drainage. FINDINGS: The existing suprapubic catheter was not in the bladder, but was instead coiled in the subcutaneous tissues. The tract to the bladder could not be identified. INTERPRETATION: The existing suprapubic catheter was not in the bladder, but was instead coiled in the subcutaneous tissues. The tract to the bladder could not be identified.
