Hi young lady, you do have both gastrointestinal and urinary problems from the information provided. The CT scan
will give us some information about how your kidneys and gallbladder
look. Are you having any white discharge per vagina which is contaminating the urine? Infection of the urinary tract
is the most common cause of pus cells in the urine. Repeat the culture. If repeated cultures are negative and there is no kidney stone on CT scan, you will need tests to look for causes of 'Sterile pyuria'. Blood in stools is not due to gallstones nor urine infection - it needs further assessment. Most commonly it is due to haemorrhoids (piles), but a doctor (surgeon/ GP) should examine you to confirm or negate this.
