Complete detailed history, examination and investigations like urine for culture and sensitivity, and radiological investigations were carried out. Results: Out of total no. of 60 cases sent for urine culture, 44 cases were culture positive. E. coli is isolated in 32 cases (53.3%). Klebsiella in 7 cases (11.6%) and pseudomonas in only 3 cases (5%) and proteus in 2 cases (3.3%). Out of total no of cases, 60 cases, 15 cases were presented with predisposing factors like vesical stones in 8 cases (13.3) noted on plain X-ray of abdomen, where as hydronephrotic changes were seen in 7 cases (11.6%). Conclusion: Organism isolated in present study E. coli (53.3%) was commonest organism isolated, then followed, by Klebsiella, Pseudomonas and Proteus.
