Preoperative intermittent catheterization in patients with prostatic hypertrophy.

Area of Science:

• Urology
• Infectious Disease

Background:

• Urinary tract infections (UTIs) are a common complication following prostatectomy.
• Catheterization methods, indwelling vs. intermittent, may influence UTI risk.

Purpose of the Study:

• To compare the incidence of bacteriuria in patients undergoing prostatectomy based on their preoperative voiding status and catheterization method.
• To evaluate the effectiveness of intermittent catheterization versus indwelling catheterization in preventing bacteriuria.

Main Methods:

• Retrospective analysis of 259 patients undergoing transurethral or retropubic prostatectomy.
• Categorization of patients based on preoperative voiding status: spontaneous voiding, intermittent catheterization, or indwelling catheter.
• Comparison of preoperative and postoperative bacteriuria rates across different groups.

Main Results:

• Postoperative bacteriuria rates were 39% for spontaneous voiders, 50% for intermittent catheter users, and 84% for indwelling catheter users.
• Patients with indwelling catheters exhibited the highest preoperative (62%) and postoperative (84%) bacteriuria rates.
• Intermittent catheterization showed lower bacteriuria rates than indwelling catheterization.

Conclusions:

• Intermittent catheterization is associated with a lower risk of bacteriuria compared to indwelling catheterization in prostatectomy patients.
• Patients with urinary retention or residual urine should preferably use intermittent catheterization to minimize infection risk.
• Findings support the adoption of intermittent catheterization as a safer alternative to indwelling catheters for managing urinary issues post-prostatectomy.
