Prostate Radiotherapy Bladder Volume Reproducibility Improves with Nurse-Led Support
A NURSE-LED bladder management approach improved bladder volume reproducibility and reduced repeat imaging in prostate hypofractionated radiotherapy.
In a retrospective analysis, investigators evaluated 60 patients with prostate cancer receiving hypofractionated radiotherapy at 51.6 Gy in 12 fractions. Twenty patients received intervention from a Certified Nurse in Radiation Oncology nursing, while 40 received standard nursing guidance alone. The newer intervention combined dehydration risk assessment with handheld bladder ultrasound guidance from the first treatment session.
Bladder Volume Reproducibility Was Significantly Higher
The study found no significant difference in bladder volume at treatment planning between groups. However, mean bladder volume reproducibility during treatment was significantly better in the nurse-led intervention group at 96.5% versus 86.9% in the standard care group. The predefined goal was at least 70% reproducibility, calculated by comparing treatment bladder volume with planning bladder volume.
This finding is clinically relevant in hypofractionated prostate radiotherapy, where consistent bladder filling is especially important for maintaining treatment accuracy and limiting unnecessary variation in organ position.
Fewer Repeat CBCT Scans May Reduce Radiation Exposure
The intervention also improved treatment workflow. In the nurse-led group, treatment began after the first cone-beam computed tomography scan in 95.4% of sessions, compared with 80.0% in the previous intervention group. This suggests fewer repeat CBCT acquisitions were needed before treatment could proceed.
The nursing intervention focused on identifying patients at risk of inadequate bladder filling before treatment rather than reacting after poor reproducibility had already been seen on imaging. Patients with dehydration risk underwent individualized fluid management and repeat bladder scanner checks before entering the treatment room.
The authors concluded that Certified Nurse in Radiation Oncology nursing intervention can strengthen bladder volume reproducibility and help reduce CBCT frequency, potentially lowering imaging-related radiation exposure for patients undergoing prostate hypofractionated radiotherapy.
