Overview

There are several life-threatening causes of back pain, including spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. These should be evaluated alongside other possible causes of back pain by carefully assessing the nature of the pain, and obtaining a thorough patient history.

 ==Overview==
-There are several life-threatening causes of back pain which need to be evaluated for first, which include; spinal cord or cauda equina compression, aortic dissection, aortic aneurysm, vertebral osteomyelitis, epidural abscess, and metastatic cancer. The other possible causes of back pain can be evaluated for by carefully assessing the nature of the pain, and obtaining a thorough patient history.

+*To rule out [[anemia]]

+*To rule out [[nephrolithiasis]]
+BUN and serum creatinine
+*To assess kidney function
+Urine culture
+*To rule out [[urinary tract infection]]
+|Voiding cystourethrography
+*May demonstrate [[vesicoureteral reflux]]

+*Dilation of collecting system
+*Annular stricturing
+IVP
+*May demonstrate a hydronephrotic kidney
+*Used to map out entire urinary system
+CT and MRU
+*Provides detail about the urinary system such as;
+**Renal vasculature
+**Renal pelvis anatomy
+**Location of crossing vessels
+**Renal cortical scarring
+**Ureteral fetal folds in the proximal ureter
+Doppler
+*Used to detect cross vessels associated with obstruction

+*May demonstrate aberrant renal vessels
