Abstract:
The influence of gram-positive cocci on the postoperative course of transurethral prostatectomy was analysed on 463 patients. The half of isolated cocci was Enterococcus, followed by S. epidermidis and S. aureus. The rates of postoperative urinary infection by gram-negative bacilli were nearly the same for patients with preoperative gram-positive cocci infection and those without any of bacteria (3/79 vs. 9/310). Patients who developed new infection with gram-negative bacilli had fever, in contrast to patients with new gram-positive cocci infection. Gram-positive cocci prolonged the postoperative pyuria but not so long as gram-negative bacilli. All these findings suggest that infection caused by gram-positive cocci is not so severe as that caused by gram-negative bacilli.
Insights
Gram-positive cocci infections prolong postoperative pyuria after transurethral prostatectomy but are less severe than gram-negative infections. Enterococcus was the most common cocci identified in this study.
Area of Science:
- Urology
- Infectious Diseases
- Microbiology
Context:
- Transurethral prostatectomy (TURP) is a common surgical procedure.
- Postoperative infections can complicate patient recovery.
- The role of specific bacterial types in TURP outcomes requires further elucidation.
Purpose:
- To investigate the impact of gram-positive cocci on the postoperative course of transurethral prostatectomy.
- To compare the severity of gram-positive cocci infections with gram-negative bacilli infections following TURP.
Summary:
- A study analyzed 463 patients undergoing transurethral prostatectomy.
- Enterococcus, Staphylococcus epidermidis, and Staphylococcus aureus were the predominant gram-positive cocci identified.
- Gram-positive cocci prolonged postoperative pyuria but did not significantly increase the rate of gram-negative urinary tract infections compared to patients without preoperative cocci.
- Patients with new gram-negative infections experienced fever, unlike those with gram-positive cocci infections.
Impact:
- Gram-positive cocci infections following TURP appear to be less severe than gram-negative infections.
- Findings suggest distinct clinical trajectories based on the causative pathogen in postoperative urinary tract infections.
- This information can aid in tailoring patient management and antibiotic strategies.
