Patients who have urinary catheters in place upon hospital admission for transurethral resection of the prostate (TURP) are at increased risk of post-operative urinary tract infections (UTIs), investigators reported at the 24th Annual European Association of Urology Congress in Stockholm.

Of 599 TURP patients, 196 (32.7%) were aged 65 years and younger and 403 (67.3%) were older than 65. The rates of UTI following TURP were 9.2% and 11.2% in the two groups, a non-significant difference.

Post-operative UTIs developed in 17.3% of patients with urinary catheters on admission compared with 6.7% among those without catheters at admission, according to findings presented by Mete Çek, MD, of Taksim Teaching Hospital in Istanbul, Turkey, and colleagues. UTIs developed in 13.2% of patients who were receiving antibiotics before and until TURP versus 7.8% who were not receiving antibiotics.

Of the men who did not have catheters on admission or who had a catheter in place for seven days or less, 7.9% experienced a post-operative UTI compared with 19.1% of patients who had catheters in place for more than a week. In addition, post-operative UTIs developed in 18.7% who had a catheter replaced within the last week preoperatively compared with 9.9% of those who did not have a catheter replaced.
