[Pharmacologic prevention of postoperative cystitis]

Area of Science:

• Urology
• Infectious Diseases
• Pharmacology

Context:

• Postoperative cystitis is a common complication following surgical procedures.
• Bacterial adherence to the urothelium is a key factor in developing cystitis.
• Current prophylactic drug options include nitrofurantoin and trimethoprim with clotrimoxazole.

Purpose:

• To compare the efficacy of nitrofurantoin and trimethoprim with clotrimoxazole in preventing postoperative cystitis.
• To assess the impact of these drugs on bacterial adherence to the urothelium.
• To evaluate the tolerability and optimal usage of these agents in a surgical context.

Summary:

• Nitrofurantoin significantly reduced postoperative cystitis rates in both abdominal (12.3% to 2.3%) and vaginal (46.1% to 9.6%) operations.
• Trimethoprim with clotrimoxazole showed a less pronounced effect, reducing rates in vaginal operations (46.1% to 24.5%) but not significantly impacting abdominal operations (12.3% to 12%).
• Nitrofurantoin requires daily administration and has tolerability issues, while trimethoprim with clotrimoxazole offers a single-dose pre-operative option suitable for short-term catheterization.

Impact:

• Nitrofurantoin demonstrates superior efficacy in preventing postoperative cystitis, particularly after vaginal surgeries.
• Trimethoprim with clotrimoxazole is a viable, albeit less potent, alternative for specific patient groups and procedures.
• Drug selection should consider efficacy, patient tolerability, and duration of catheterization to optimize cystitis prevention strategies.
