Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 65
Abstract
BACKGROUND The PCN catheter urine culture is important in cases of complicated urinary tract infections, especially in obstructive uropathy. It is therapeutic as well as diagnostic. The aim of this study was to compare the results of urine cultures obtained either from urethral or percutaneous nephrostomy (PCN) catheters. MATERIALS AND METHODS This study included 78 consecutive patients that underwent PCN at our institution with complicated urinary tract infections (UTIs) between July 2016 and June 2017. Results of urine cultures obtained from the urethral and nephrostomy catheters were compared. RESULTS This study included 56 male and 22 female patients. Mean age of the patients was 15 - 55 years. The main indications were obstructive uropathy due to urolithiasis and PUJO complicated with pyonephrosis 43 (55%), malignant disease (n= 20; 25%), pregnancy (n= 4; 5%) and others (n= 11; 15%); 13 patients had diabetes mellitus. The most common causative organisms were Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Blood cultures showed the same results for the PCN and bladder urine cultures. The urethral urine culture was positive in 71 patients, while the PCN urine culture in 76 patients. CONCLUSION PCN is an important treatment for the management of pyonephrosis. Cultures from the PCN yield valuable information that is not available from urethral urine cultures and is a guiding tool for antibiotic therapy selection.
