Intraprostatic Tissue infection in catheterised patients in comparison to controls.
J Pak Med Assoc Jan ;54(1):20-4.

Objective: To determine the effect of indwelling urinary catheter on frequency of intraprostatic tissue infection and post-operative morbidity in patients with benign prostatic hyperplasia undergoing transurethral resection of prostate (TURP). Methods: Frequency of intraprostatic tissue and urinary infection, prevalent organisms, histopathology of prostatic tissue, post-operative morbidity were analyzed for 25 consecutive patients of clinically diagnosed benign prostatic hyperplasia who underwent TURP in cathertized and non-catherized groups. Results: Patients mean age was 62.27.9 years. In non-catherized group nocturia and frequency were the most common symptoms. Ninety two percent and 28% patients acquired intraprostatic tissue infection in catheterized and non-catherized group respectively, while 80% of catherized patients and 24% of the non-catherized patients had bacteruia. Catherized patients had E. coli as prevalent organism both in intraprostatic tissue and urine (34.8% and 40% respectively). E. coli, serratia and enterobacter were equally prevalent in intraprostatic tissue of non-catherized patients. Enterobacter was the prevalent organism in urine (50%) of these patients. There was no significant difference in the presence of non-specific inflammatory cells in the two groups. Catherized group showed significantly high frequency of fever >38.5C and hematuria for more than 24 hours. Conclusion: Catherization significantly increases the frequency of intraprostatic tissue infection as well as morbidity of TURP (JPMA 54:20;2004).
