Early Removal of Urinary Catheters in Patients After Rectal Surgery: a Prospective Study

All patients undergoing anterior resection (rectosigmoid), low anterior resection,
abdomino-perineal resection, total proctocolectomy with ileal pouch-anal anastomosis,
sigmoid colectomy, and coloanal anastomosis will be included in the study. All patients will
undergo standard pre-operative work-up prior to the operation. As part of the operative
note, the level of the anastomosis must be documented.

1. All patients will have foley catheters removed between 0600 and midnight of
post-operative day 3 (Day 0 being the day of operation).

2. All patients will undergo bladder ultrasound prior to catheter removal.

3. All patients will undergo bladder ultrasound by nursing staff six hours after catheter
removal, and after voiding the first time after catheter removal, or if the patient
experiences symptoms of urinary retention.

6. Patients who meet definition of urinary retention (>100cc post-void residual) will
undergo intermittent straight catheterization every six hours or with symptoms. For those
who refuse intermittent straight catheterization, a indwelling urinary catheter will be
inserted and left in for 24 hours before removal.

7. For patients who have low urine output indicating under-resuscitation, indwelling
catheters will be re-inserted and removed when ongoing resuscitation measures are completed.

8. For patients who are actively undergoing fluid resuscitation on post-operative day 3 will
not have their urinary catheters removed until resuscitation and monitoring is complete.

9. Patients who report symptoms of benign prostatic hypertrophy (BPH) and/or are already on
medications for BPH will be continued on those medications starting on post-operative day 1.

10. Patients who have persistent urinary retention when they are otherwise ready to be
discharged home will be sent home with a leg bag and follow up in urology clinic for voiding
trial in 1-2 weeks.

11. Urinalysis/urine culture will be performed for symptomatic patients.
