Endometritis, post surgical infection, mastitis, genital tract infection, perineal cellulites, respiratory complication from anaesthesia, retained product of conception, urinary tract infection and septic pelvic phlebitis are the post partum infection. To find out urinary tract infection in caesarean section. This prospective cohort study was conducted in the Department of Gynae and Obstetrics, Holy Family Red Crescent Medical College Hospital from August 2003 to January 2004 over a period of six months. Two hundred pregnant patients age between 15 to 42 years, both primi & multipary, pre term, term and post term cases were included in this study. Patients having fever prior to caesarean section were excluded from this study. Out of 200 caesarean section cases history of previous caesarean section (33.5%), Fetal distress (31%), preeclampsia (9.5%), cephalopelvic disproportion (8%), placenta praevia (6.5%) obstructed labour (4.5%), bad obstetric history (3.5%), early rupture of membrane (3.5%). Term delivery was 77%, preterm was 16.5% and post term was 6.5% in this study. 43.0% cases was primi para and 56.5% was multipara. 22 (11.0%) cases of study population had a history of UTI during pregnancy and only 29 (14.5%) cases developed urinary tract infection. Out of 29 cases only 3 (13.6) cases had a history of urinary tract infection during pregnancy. But there was no wound infection after caesarean section in this study. Urinary tract infection is probably due to improper aseptic precaution during catheterization. Organism isolated from urine were pseudomonas (44.8%), Klebsilla (24.1 %), E.coli (20.7%), proteus (10.3%). In this study, 29 (14.5%) cases developed UTI following caesarean section and only 3 03.6%) cases had a history of UTI during pregnancy.
