What is the diagnosis for a patient with mild left hydroureteronephrosis secondary to a 2mm calculus at the left ureterovesical junction, hematuria (blood in urine), and few bacteria, with urinalysis showing 11-29 red blood cells (RBC) per high power field (hpf)?

Differential Diagnosis for Left Hydroureteronephrosis and Urinalysis Results

  • Single Most Likely Diagnosis
    • Urinary tract infection (UTI) with ureteral obstruction: The presence of bacteria and blood in the urine, along with the finding of a 2mm calculus at the left ureterovesical junction, suggests a UTI complicated by a ureteral obstruction. The obstruction is likely causing the hydroureteronephrosis.
  • Other Likely Diagnoses
    • Ureteral stone with associated inflammation: The 2mm calculus could be causing inflammation and irritation in the ureter, leading to the blood and bacteria in the urine.
    • Pyelonephritis: The presence of bacteria and blood in the urine, along with the hydroureteronephrosis, could indicate an infection of the kidney (pyelonephritis).
  • Do Not Miss Diagnoses
    • Ureteral tumor or cancer: Although less likely, a tumor or cancer in the ureter could be causing the obstruction and hydroureteronephrosis. This diagnosis would have significant implications for treatment and prognosis.
    • Septic shock or urosepsis: If the UTI is severe and untreated, it could lead to septic shock or urosepsis, which are life-threatening conditions.
  • Rare Diagnoses
    • Tuberculosis of the urinary tract: This is a rare condition that could cause similar symptoms, including hematuria and urinary tract obstruction.
    • Sarcoidosis or other granulomatous diseases: These conditions could cause inflammation and obstruction in the urinary tract, although they are relatively rare.
    • Foreign body in the ureter: Although unlikely, a foreign body in the ureter could cause obstruction and hydroureteronephrosis.
