[Bacteriuria after Radical Prostatectomy: Importance of Bacterial Count].

Area of Science:

• Urology
• Infectious Diseases
• Nephrology

Background:

• Post-radical prostatectomy patients may experience discomfort potentially linked to urinary tract infections (UTIs).
• The management of asymptomatic bacteriuria in this population requires careful consideration to avoid unnecessary antibiotic use.

Purpose of the Study:

• To evaluate the necessity of antibiotic treatment for patients with low bacterial counts in urine following radical prostatectomy.
• To determine the utility of urine dipstick tests in ruling out significant bacteriuria in post-operative urological patients.

Main Methods:

• A prospective study followed 100 consecutive patients post-radical prostatectomy with initial midstream urine bacterial counts of 10^4 CFU/ml.
• Patients were managed without antibiotics during inpatient rehabilitation, with follow-up urine dipstick tests and cultures performed before discharge.

Main Results:

• No symptomatic UTIs were observed during the average 15.2-day follow-up period.
• Unremarkable urine dipstick findings (negative for leukocyturia, hematuria, and nitrituria) correlated with the absence of relevant bacteriuria (≥10^5 CFU/ml).
• Of 15 patients with bacterial counts ≥10^5 CFU/ml, only 4 (27%) presented with systemic infection symptoms and were treated with antibiotics; the rest were monitored.

Conclusions:

• Antibiotic treatment should be reserved for post-radical prostatectomy patients with confirmed bacteriuria and clear systemic signs of infection (fever, chills, leukocytosis).
• Negative urine dipstick results reliably exclude significant bacteriuria (≥10^5 CFU/ml) in this patient cohort.
• Conservative management and targeted antibiotic therapy for symptomatic cases are effective in preventing complications.
