Ex : men, pregnant , diabetic , renal faliure , Hx of pyelonephritis , cath , AB resistant organism , immunocompromised ,recent hospotalization , recent AB exposure

7. Clinical features
Dysuria … expressed ? Frequency Urgency VS hesitation Tenderness …site ?? Sometime …gross hematuria What is characteristically ABSENT ?

8. diagnosis
1)Dipstick urine analysis Look for leuko est and nitrite (+) leuko est menas ? (+)nitrites mean ?

10. diagnosis
2)Urinalysis Clean catch midstream specimen ? Criteria : *Bacteruria : >1 organism/oil immersion field Bacteruria without pyuria isn’t reliable *pyuria : greater than or equal 10 leuko/micro L

11. Urine culture
Acute non complicated ?? Indicated in : 1)Asymptomatic bacteruria ??? When diagnosed ? In which patients ??? 2) Suspected pyelonephritis , complicated , recurrent UTI , suspicion of resistant organism *criteria : >= 10^5 CFU/mL , 2 to 4 is enough if symptoms & signs are present !

12. Complications
1)Upper spread (pyelonephritis / prostaties / urosepsis ) Risk factors : pregnancy , DM , VUR ! 2)During pregnancy : preterm labor , LBW . 3)Recurrence

13. Treatment
In acute uncomplicated : Bactrim 3 days ( oral TMP/SMX) & Nitrofurantoin 5-7 days We can also use : fosfomysin single dose or Fluroquinolones ( cipro 3 D regimen ) Urinary analgesic : phenazopyridine 1-3 days Don’t use nirtofurantoin or fosfomycin if PN is suspected !! If didn’t respond for short AB , treat for PN

14. Treatment
Pregnancy : Amicillin , amoxicillin or oral cephalosporins for days Avoid fluoroquinolones , fetal arthropathy

15. treatment
Men : as in uncomplicated but for 7 days
