Scan Before You Catheterize: A Capstone Change Project on Postoperative Urinary Retention After Joint Replacement
Introduction
Urinary retention after surgery is a common problem that nurses manage many times a week, often without a standard approach. On orthopedic units, where many patients receive spinal anesthesia and opioids after hip or knee replacement, the question of when to catheterize a patient who has not voided is often answered by habit, by the clock or by whoever is on shift. This capstone proposes a nurse-driven bladder scan protocol for patients after total joint replacement. Its central argument is that measuring before acting protects patients from two opposite harms: bladders stretched too far and catheters placed without need.
The Problem on the Unit
The composite 28-bed orthopedic unit in this project performs about 840 hip and knee replacements a year. A review of 420 consecutive patients over six months found that 96 had at least one straight catheterization after surgery. For 37 of those 96 patients, 38.5 percent, no bladder scan was documented before the catheterization, and in 11 patients the first catheterization drained more than 800 milliliters, a volume that risks bladder overdistension injury. Another 21 patients had indwelling catheters placed on the day of surgery without a documented retention episode. Two patients developed catheter-associated urinary tract infections. Nurses described inconsistent practice: some scanned routinely, others waited for patient discomfort, and many were unsure what volume should prompt catheterization.
Evidence
Postoperative urinary retention is common and has recognized causes. A comprehensive review of anesthetic and perioperative considerations described how spinal anesthesia, opioids, anticholinergic drugs and large intravenous fluid volumes can impair bladder emptying, and recommended assessment of bladder volume by ultrasound to guide catheterization rather than relying on symptoms alone (Baldini et al., 2009). Overdistension can damage the detrusor muscle, while unnecessary catheterization adds infection risk and discomfort.
Retention is especially frequent after joint replacement. In a prospective observational study of patients undergoing fast-track total joint replacement of the lower limb, 46.3 percent were catheterized for urinary retention, and spinal anesthesia was associated with retention (Scholten et al., 2018). Infection guidance recommends avoiding indwelling catheters when possible, using intermittent catheterization when needed, and using portable ultrasound to assess urine volume and reduce unnecessary catheterization (Gould et al., 2010). Together, the evidence supports routine bladder volume measurement and clear volume thresholds to guide action.
Nursing measures matter alongside the scan. Helping patients sit or stand to void, providing privacy, running water and adequate pain control can resolve many episodes without a catheter, and early mobilization after joint replacement supports normal bladder function. The protocol therefore pairs scanning with these simple interventions before catheterization at moderate volumes.
The Proposed Protocol
The protocol, approved as a standing nursing order, applies to adults after hip or knee replacement without an indwelling catheter.
Table 1
Nurse-Driven Bladder Scan Protocol After Joint Replacement
| Situation | Nursing action |
|---|---|
| Has not voided within 6 hours of arrival on the unit, or reports urgency or discomfort | Perform bladder scan |
| Scan under 400 mL | Encourage voiding with privacy and upright position; rescan in 2 hours |
| Scan 400 to 600 mL without discomfort | Assist to commode or bathroom; rescan in 1 hour if unable to void |
| Scan over 600 mL, or over 400 mL with discomfort | Straight catheterization per standing order; document volume |
| Two straight catheterizations within 24 hours | Notify surgeon or hospitalist to consider indwelling catheter and review medications |
| After voiding, if symptoms suggest incomplete emptying | Post-void scan; notify provider if residual over 300 mL |
Note. Thresholds are proposed values to be finalized with the orthopedic surgeons, anesthesia and urology.
Change Theory, Stakeholders and Readiness
Lewin's change model guides the project. Unfreezing will use the unit's data, especially the 11 patients with volumes over 800 milliliters, to show that current practice is inconsistent. Moving will introduce the protocol through education and champions. Refreezing will build the protocol into the postoperative order set and nursing flowsheet so that scanning prompts appear automatically.
Stakeholders include orthopedic surgeons and anesthesia providers, who must approve the standing order; staff nurses and nursing assistants, who will perform scans and support voiding; urology, which will review thresholds; the infection prevention team; and patients. Readiness is moderate: nurses support a clear protocol, but the unit has only one bladder scanner, often shared with another floor. Purchasing a second scanner was identified in pre-implementation as a condition for starting.
Implementation
Implementation will take four months. In month one, the protocol and standing order will be approved, and a second scanner purchased. In month two, nurses will complete a 30-minute session on scanner technique, interpretation and the protocol, with a return demonstration; nursing assistants will be trained in measures that help patients void. Month three will be a pilot on day and evening shifts, with champions reviewing every catheterization. In month four, the protocol will extend to all shifts. Patients will receive a short explanation before surgery that the nurse will check their bladder with a painless ultrasound if they have not voided.
Evaluation
Evaluation will compare six months after full implementation with the six-month baseline. Outcome measures are the proportion of catheterizations preceded by a documented scan, with a target of 95 percent from a baseline of 61.5 percent; the number of first catheterizations draining over 800 milliliters, with a target of zero from a baseline of 11; and the number of indwelling catheters placed without a documented retention episode, with a target of 50 percent fewer than the baseline of 21. Balancing measures include total straight catheterizations, length of stay and patient reports of discomfort. Catheter-associated urinary tract infections will be tracked, though numbers will be small. Results will be shared monthly with staff and at the end of the evaluation with the orthopedic quality committee.
Conclusion and Professional Growth
This project replaces inconsistent, habit-driven decisions about urinary retention with a simple, evidence-based rule: measure before acting. The protocol protects patients from both overdistended bladders and unnecessary catheters, gives nurses clear authority to act, and can be evaluated with data the unit already records. Developing it has changed how I see my role. Early in the RN to BSN program, I would have treated urinary retention as a task. Leading this project taught me to see it as a system problem that nurses are well placed to solve with evidence, data and collaboration.

How this NUR 490 Module 7 example is structured
The final capstone brings every earlier deliverable together, so the paper follows the life of the change from start to finish. It opens with the problem on the unit, measured over six months. The evidence section shows how common retention is after joint replacement and what harms follow from both overdistension and unnecessary catheters. The proposed protocol is set out in a decision table. Change theory, stakeholders and readiness come next, followed by the implementation timeline and the evaluation measures with baselines and targets. The conclusion connects the project back to the writer's professional development, which the capstone is designed to demonstrate.

NUR 490 Module 7 questions, answered
What does the NUR 490 Module 7 final capstone usually require?
The final capstone typically brings the change project together: every earlier piece of the project, from the problem and its evidence through the change model, the people involved and each stage of planning, and often a reflection on how the student has grown. It should read as one coherent project rather than separate assignments. Your guidelines set length and required components.
How do I combine earlier capstone parts into one paper?
Start from a single thesis about the change, then revise each earlier part so it leads into the next, removing repeated background and updating details that changed. Add transitions that explain why each stage follows from the one before, and make sure the evaluation measures match the problem data you started with.
Can the capstone focus on reducing a common nursing task?
Yes. Many strong capstones reduce low-value or poorly timed care, such as unnecessary catheters, tests or interruptions, and replace it with a clearer, evidence-based process. The key is showing the harm of current practice and a safe, practical alternative.
