Objective:

To systematically evaluate the quality of postoperative pain management after minimally invasive and open surgical kidney procedures using the Quality Improvement in Postoperative Pain Management (QUIPS) project.

Approach:

• Study Design: A prospective observational study was conducted involving 116 patients undergoing nephrectomy or partial nephrectomy.
• Data Collection: Data were collected using standardized methods as part of the QUIPS project, focusing on pain intensities, analgesic needs, side effects, patient satisfaction, and hospital stay length.

Key Findings:

• Patients undergoing minimally invasive procedures reported lower postoperative pain scores compared to those undergoing open surgery (pain on exercise: median 6 [IQR 4–8] vs. 7 [IQR 5–8], p = 0.050).
• The need for opioids was higher in patients who had open procedures [25/62 (40.3%) vs. 11/54 (20.4%); p = 0.021].
• Patient satisfaction scores were high across both surgical groups [minimally invasive: median 8 [IQR 6–10]; open: median 8 [IQR 6–9]; p = 0.905].
• Robot-assisted procedures were associated with the lowest pain scores [pain on exercise: median 5 [IQR 4–7]; maximum pain: median 6 [IQR 5–8]; minimal pain: median 0 [IQR 0–2]] and the shortest hospital stays [median 7 days (IQR 6.8–9)].

Interpretation:

Postoperative pain remains a significant issue after kidney surgery, indicating a need for tailored pain management strategies based on the surgical approach.

Limitations:

• The study was limited to a single institution.
• Pain management protocols were not standardized across all patients, which may affect the generalizability of the findings.

Conclusion:

Different surgical modalities may require procedure-adapted pain management strategies based on the findings of this study.
