Event or Problem Description
It was reported that after a difficult urethral stent placement on (b)(6) 2024, the patient returned to the hospital presenting with urosepsis on (b)(6) 2024.An abdominal computed tomography (ct) scan was performed, and it was discovered that the stent had migrated (from renal pelvis into the bladder) and therefore had to be removed and a similar device placed.The doctor reports no abnormalities with respect to the standard design of the device (product apparently not compromised) however, the doctor complains of difficulties in the placement of the stent and unable to create an adequate seal curl in the upper urinary tract, thus led to migrating of the device.There were no delays reported during procedure.
