What is the lowest Gleason score for prostate cancer?

A

6

Q

Investigation of suspected renal stone

A

FIRST do ultrasound and then if you think there is a stone, do non-contrast CT (NON-CONTRAST)
- if you use contrast then it basically becomes invisible

(can be difficult to identify and treat because might be missed if poor bowel preparation)
