On clinical examination, what accidental finding has NO connection to renal cancer?
unilateral hydrocele
bilateral varicocele
calcifications at the renal area on plain KUB film
painless hematuria
Correct Answer :
A. unilateral hydrocele
testicular hydroceles have nothing to do with renal cancers. Blocking the IVC by tumor thrombi could result in bilateral varicocele.

What is false on comparing Tc-99m DTPA to Tc-99m MAG3?
DTPA provides better quality images with renal insufficiency

DTPA provides an excellent measurement of GFR
in pediatrics, MAG3 provides better quality images than DTPA
