Bacteriology of urinary tract infection associated with indwelling J ureteral stents.

Purpose: To investigate the microorganisms responsible for urinary tract infection (UTI) and stent colonization in patients with indwelling J ureteral stents and to compare the antimicrobial susceptibility pattern of the isolates from urine and J stents in order to establish the etiologic agents of bacteriuria and colonized stents in such patients and provide baseline data on an antibiotic policy for the urology unit.

Patients And Methods: Midstream urine from 250 patients requiring J stent insertion was investigated microbiologically prior to stent insertion and on the day of stent removal. After stent removal, 3 to 5 cm of the tip located in the bladder was also sent for culture.

Factors predisposing to urinary tract infection after J ureteral stent insertion.

Purpose: We determined the group of patients most likely to have bacterial infection or colonization of J stents inserted to relieve ureteral obstruction.

Materials And Methods: Midstream urine from 250 consecutive patients who required indwelling J stent insertion obtained before stent insertion and on the day of stent removal was analyzed by microbiological testing. At stent removal 3 to 5 cm.
