Objective:
To evaluate the effectiveness of integrating 3D digital holographic reconstruction and intraoperative navigation with case-based learning (CBL) in enhancing the educational outcomes of laparoscopic partial nephrectomy training for urology residents.
Methods:
A prospective randomized controlled trial was conducted at the Second People's Hospital of Hefei from August 2021 to May 2024. A total of 120 urology residents were randomly assigned to either a combined teaching group (3D holography + CBL, n = 60) or a conventional CBL-only group (n = 60). The experimental group utilized reconstructed CT/MRI DICOM data rendered into interactive holographic models via Microsoft HoloLens 2 for real-time anatomical visualization and intraoperative guidance. Key outcome measures included post-training performance (theoretical and practical scores), self-directed learning ability, teaching satisfaction, critical thinking disposition, and knowledge retention at 1-, 3-, and 6-month follow-ups.
Results:
The combined teaching group demonstrated significantly superior outcomes across all measured domains (P < 0.05). Post-training scores were higher in theoretical knowledge (44.58 ± 2.09 vs. 40.28 ± 2.96), practical skills (44.63 ± 2.69 vs. 40.00 ± 2.64), and total score (89.21 ± 4.33 vs. 80.28 ± 5.55). Additionally, the group showed enhanced self-directed learning (4.38 ± 0.74 vs. 3.07 ± 0.73), higher teaching satisfaction (4.30 ± 0.74 vs. 3.15 ± 0.58), and improved critical thinking, notably in analyticity and cognitive maturity. Longitudinal assessments revealed better knowledge retention at all time points, with 6-month total scores of 76.92 ± 2.25 vs. 60.77 ± 5.97.
Conclusions:
Integrating 3D holographic reconstruction and intraoperative navigation into CBL teaching significantly improves urology residents' comprehension, critical thinking, surgical preparedness, and long-term knowledge retention during laparoscopic partial nephrectomy training. This multimodal teaching model may serve as a valuable adjunct to traditional residency training frameworks.
