A prospective, randomized trial comparing continuous bladder drainage with catheterization at abdominal hysterectomy

Area of Science:

• Urology
• Gynecologic Surgery
• Infectious Disease

Background:

• Urinary catheterization is common during gynecologic surgery.
• The choice between indwelling and in-out catheterization may impact patient outcomes.
• Understanding post-operative urinary complications is crucial for patient recovery.

Purpose of the Study:

• To compare infection rates and post-operative morbidity between indwelling urinary catheterization and 'in-out' catheterization.
• To evaluate the incidence of urinary retention and bacteriuria following different catheterization methods.
• To assess the implications for long-term bladder function after hysterectomy.

Main Methods:

• A randomized controlled trial involving 100 patients undergoing total abdominal hysterectomy.
• Patients were blindly randomized to receive either an indwelling Foley catheter or an 'in-out' catheterization.
• Follow-up data collected on urine retention, urinary symptoms, and infection.

Main Results:

• 36% of patients with 'in-out' catheterization experienced post-operative urinary retention versus 4% with indwelling catheters (P < 0.001).
• Urinary tract bacteriuria occurred in 29% of the indwelling catheter group compared to 13% in the 'in-out' group (P < 0.025).
• Indwelling catheterization showed significantly lower rates of urinary retention.

Conclusions:

• 'In-out' urinary catheterization during hysterectomy is linked to higher post-operative urinary retention.
• Indwelling catheterization appears to be a safer option regarding immediate post-operative urinary complications.
• The findings suggest potential implications for long-term bladder health, favoring indwelling catheterization.
