Abstract

Introduction and hypothesis: Postoperative urinary retention is common after urogynecologic procedures. Our objective is to determine the efficacy of force of stream (FOS) assessment without a visual analog scale for postoperative catheter management.

Methods: We conducted a retrospective cohort study of 110 women undergoing an inpatient gynecologic procedure. They were asked to subjectively assess FOS after surgery without a visual analog scale. If it was 50% or better than the usual preoperative void, they were discharged home without a catheter. If < 50%, the catheter was replaced and the patients were sent home and asked to follow up in 3 to 5 days for another void trial.

Results: Average age was 56.9 ± 10.2 years; 63.6% underwent surgery for pelvic organ prolapse, 23.6% underwent sling for urinary incontinence, and 12.7% underwent a combination of both. Force of stream was > 50% in 93.6% of the patients; 6.4% had force of stream < 50% and hence were discharged home with a Foley catheter. Only two patients (1.8%) were discharged without a Foley catheter and returned to the emergency department for signs of urinary retention. Sensitivity, specificity, positive and negative predictive values were 77.8%, 100%, 100% and 98.1%, respectively.

Conclusion: The subjective assessment of flow of stream is a reliable and safe method to assess postoperative voiding. Given it is less invasive than backfilling the bladder and easier than using a bladder scan, it should be the primary method to assess postoperative voiding.

Keywords: Force of stream; Urogynecology; Voiding.
