HISTORY: RED BLOOD CELLS IN URINE; hematuria
COMPARISON: None ;    

TECHNIQUE: CT of the abdomen and pelvis is performed before and following
intravenous 100 mL of
Isovue-300.  No oral given. ; This study was performed using dose reduction
techniques to include
automated exposure control and/or adjustment of the mA and/or kV according to
patient size.

FINDINGS: Precontrast imaging reveals a 7.5 mm round calculus in the right renal
pelvis.  There is
surrounding thickening and hyperenhancement of the urothelium in the renal
pelvis and proximal right
ureter.  There is no distal ureteral calculus or hydronephrosis on either side. 
No calculi seen in the
left kidney.

After contrast, no suspicious enhancing lesion identified in the kidneys.  No
striated nephrogram
observed.

Abdomen CT: Remaining major solid organs are intact.  No adenopathy. 
Gallbladder appears normal.  No
mesenteric or retroperitoneal adenopathy.  No dilated bowel.

Pelvic CT: Normal appendix.  Normal-appearing bladder and prostate.  Scattered
phleboliths are noted.  No
free fluid or adenopathy.  No enhancing bladder lesion or bladder calculus.

Lung bases: Clear

Bones: Thoracic lumbar spondylosis.  Bilateral hip osteoarthritis.

IMPRESSION:
1.  7.5 mm calculus in the right renal pelvis without hydronephrosis
2.  Associated surrounding pyelitis and ureteritis is noted; consider urinary
tract infection and
correlate with urinalysis.
3.  Thoracolumbar spondylosis and bilateral hip arthropathy
