Differential Diagnosis for Invasive Procedure for Placing Urine Catheter

• Single most likely diagnosis:
  • Urinary Retention: This is the most likely diagnosis as the patient is undergoing an invasive procedure for placing a urine catheter, which is commonly done to relieve urinary retention.
• Other Likely diagnoses:
  • Neurogenic Bladder: This condition can cause urinary retention or incontinence due to nerve damage affecting bladder control, making catheterization necessary.
  • Benign Prostatic Hyperplasia (BPH): Enlargement of the prostate can obstruct urine flow, leading to the need for catheter placement.
  • Urinary Tract Obstruction: Blockages in the urinary tract, such as kidney stones, can prevent normal urination, necessitating catheterization.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
  • Septicemia from Urinary Tract Infection (UTI): If the patient has a UTI, especially one that has ascended to the kidneys (pyelonephritis), catheterization could introduce bacteria into the bloodstream, leading to septicemia, a potentially life-threatening condition.
  • Post-Renal Acute Kidney Injury (AKI): Obstruction of urine flow can lead to AKI, which is a medical emergency requiring prompt intervention.
• Rare diagnoses:
  • Spinal Cord Injury: Though rare, if the patient has suffered a spinal cord injury, it could result in neurogenic bladder, necessitating catheterization.
  • Malignant Obstruction: Tumors in the urinary tract can cause obstruction, requiring catheter placement for urine drainage.
  • Congenital Anomalies of the Urinary Tract: Certain birth defects can affect the urinary system, potentially leading to issues that require catheterization.
