Brief summary
It is common practice to insert a Foley catheter into the bladder to drain urine during and after a lung resection. Recently, there has been increasing interest in the potential risks associated with this catheterization, particularly with regard to infection. As thoracic surgery adopts minimally invasive surgical techniques, the need for urinary catheterization during surgery is being questioned since these less invasive surgeries are known to result in less post-operative acute pain, shorter length of stay, and other outcomes that tend to decrease overall anesthetic needs for this patient population. Thus, there is a need to investigate whether patients who have had a minimally invasive lung resection truly need the Foley catheter at all. This will be achieved by assigning patients to either an experimental no-catheter group or the standard of care routine urinary catheter group to determine if patients with no catheter experience different rates of complications. This pilot study will primarily determine if there is a difference in post operative urinary complications between the groups. It is hoped that this study will definitively determine whether a Foley urine catheter is a necessary procedure in the course of a minimally invasive lung resection.
Detailed description
Urinary catheterization is standard practice during and shortly after lung resections. The standard practice is being questioned in an era where unnecessary interventions are being re-considered, particularly since urinary catheterization is not without a risk of adverse events. The study is being done to establish an evidence base to support widespread discontinuation or continuation of this standard practice. Consenting patients will be randomized to either the catheterized or non-catheterized arms. Patient urinary management will be managed as per an a priori-defined protocol that follows St. Joseph's Healthcare Hamilton (SJHH) institutional standards.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative urinary complications | From the time of surgery to post-operative Day 14. | Compating the difference in the rate of the occurrence of one or more of postoperative urinary tract infection, postoperative urinary retention requiring 1 catheterization, and postoperative urinary retention requiring more than 1 catheterization between the catheterized and the non-catheterized arms |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Post-operative Hypotension | During patient hospital stay (Estimated to be between post-operative day 0 and day 7) | Post-operative hypotension will be defined as systolic blood pressure less than 80 mmHg for \> 6 hours requiring active fluid resuscitation. The comparison will be made of rate of occurrence between the catheterized and non-catheterized arms to account for varied volumes of fluid intake that may confound observations |
| Total IV fluid administration | First 48 hours of the perioperative period | The comparison will be made of rate of occurrence between the catheterized and non-catheterized arms to account for varied volumes of fluid intake that may confound observations |
| Length of Hospital Stay | During patient hospital stay (Estimated to be between post-operative day 0 and day 7) | Comparing the total length of hospital stay between the catheterized and non-catheterized arms |
| Rate of peri-operative pulmonary complications | During patient hospital stay (Estimated to be between post-operative day 0 and day 7) | Pulmonary complications defined as Grade II or greater according to the Ottawa Thoracic Morbidity and Mortality (TM&M) scale (requiring treatment). The comparison will be made of rate of complication occurrence between the catheterized and non-catheterized arms |
| Rate of peri-operative cardiac complications | During patient hospital stay (Estimated to be between post-operative day 0 and day 7) | Cardiac complications defined as Grade I or greater according to the Ottawa Thoracic Morbidity and Mortality (TM&M) scale (no treatment required). The comparison will be made of rate of complication occurrence between the catheterized and non-catheterized arms |
| Validity of the bladder scanner tool relative to actual urine output | During patient hospital stay (Estimated to be between post-operative day 0 and day 7) | In patients who underwent a bladder scan for suspected urinary retention (Failure to pass urine within 8 +/-2 hours of de-catheterization or after surgery), it is necessary to measure how accurate the bladder scan procedure is relative to the actual amount of urine in the bladder. The bladder scanner will generate an estimate of the amount of urine in the bladder, but the accuracy is not known. The volume of urine collected from the catheter by nursing staff or as measured from a urine collection hat and compared to the reading from the bladder scanner |
