Early Foley Catheter Removal after Segmental Colectomy With Colovesical Fistula Closure for Patients With Complicated Diverticulitis: A Single-Arm, Prospective Trial.

Benjamin Gallant et al. · Annals of surgery · 2026
Background

CVF secondary to diverticulitis are typically treated with segmental resection and CVF closure, followed by postoperative bladder decompression using a Foley catheter.

Purpose

To evaluate the safety of early Foley catheter removal after segmental colectomy with colovesical fistula (CVF) closure in patients with diverticulitis.

Methods

This single-arm prospective trial (NCT05235204), conducted at a tertiary academic center from 6/2019-10/2025, included patients undergoing segmental colectomy with CVF closure for diverticular CVF.

90.8%
Results
Most patients had their urinary catheter removed early after bladder-bowel surgery
More results

65 patients were studied.

Of these, 56 (86.2%) underwent CVF closure without bladder repair, seven (10.8%) required single-layer bladder repair, and two (3.1%) required two-layer bladder repair.

All post-repair intraoperative leak tests were negative.

More results

Readmission occurred in 4 patients (6.2%) within 30 days and 7 (10.8%) within 90 days.

“
Conclusion · 1 of 2

Our study demonstrates the safety of early Foley removal, with no bladder leaks, Foley reinsertions, or CVF recurrences observed.

Conclusion · 2 of 2

Early Foley removal should be considered for adoption as routine clinical practice following closure of CVF due to diverticulitis.
