Abstract

Objective: To compare the infection rate and post-operative morbidity between in-dwelling urinary catheterization and 'in-out' catheterization at the time of routine total abdominal hysterectomy.

Patients and methods: The study comprised 100 patients who were blindly randomized to have either an indwelling Foley catheter or an 'in-out' catheterization at the time of surgery. Follow-up data on the retention of urine, urinary symptoms and infection were obtained.

Results: Of the 95 patients with complete data, 36% of those undergoing in-out catheterization had urinary retention after operation, requiring bladder emptying, compared with 4% of those receiving an indwelling catheter (P < 0.001). In addition, 29% of the catheterized group had urinary tract bacteriuria compared with 13% of the uncatheterized group (P < 0.025).

Conclusion: This randomized controlled trial showed that in-out urinary catheterization at the time of routine abdominal hysterectomy was associated with a significantly higher incidence of post-operative urinary retention compared with in-dwelling catheterization, and may have implications for long-term bladder function.
