Other Studies:
CT abdomen and pelvis with and without contrast: severe left hydronephrosis with ureteropelvic junction (UPJ) obstruction without apparent stone or mass. An adjacent lower pole renal vein may cross over the ureter but hard to tell. Delayed excretion prevents enhancement of the collecting system and ureter.
<br>Renal ultrasound: moderate-severe left hydronephrosis. <a href="CaseStudyImages/CS1WhenLowerBackPain-1195.jpg" title="Case Photo #1" data-lity><b>Case Photo #1</b></a>
<br>Lasix-challenged renal scintigraphy: severe function asymmetry between kidneys with no evidence of significant function contribution by the left kidney in the 30-minute study. <a href="CaseStudyImages/CS2CS1WhenLowerBackP-1195.jpg" title="Case Photo #2" data-lity><b>Case Photo #2</b></a>
