Q
Why do uncircumcised males get more urinary tract infections than those who are circumcised?
A
Because the foreskin can hold pathogens inside

121
Since hypertension plays a good role in most kidneys problems how are we going to help aid the patient with hypertension who has AKI?
Well the most common cause of hypertension in aki is over expansion of the ECF and plasma.
Usually we are going to be given kids beta blocks like labetalol and sodium nitroprusside
