Patient-specific 3D printed kidney models improved comprehension and satisfaction compared to conventional 2D CT scans in PCNL patients.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is a crucial treatment for large renal stones and has a high success rate. Patients require comprehensive information about the procedure to make informed decisions. Effective communication between patients and physicians is essential for treatment adherence and postoperative recovery. Utilizing three-dimensional (3D) models has been shown to improve comprehension of complication and increasing confidence in both treatments and surgeons. METHOD: This study involved 40 individuals planned for PCNL surgery, aged 18 to 80, confirmed through computed tomography (CT) scans. They were divided randomly into 2D and 3D groups. The 3D group received detailed information using patient-specific 3D printed kidney models, while the 2D group received education based on conventional 2D CT scan. After the educational session, participants completed a survey to assess their comprehension. Following surgery, participants rated their satisfaction on scale of 1-10. This study aimed to compare the effectiveness of 3D models in patient comprehension and satisfaction in PCNL surgery. RESULT: The analysis was performed on 40 individuals (23 males, 17 females). Each group comprises 20 participants, with similar demographic and stone feature characteristics. Participant ages ranged from 32 to 66 years with a mean (SD) of 50.0 (8.52) and no significant age or gender differences were seen between the groups. Patients in the 3D group showed significantly higher comprehension in various aspects and satisfaction levels (-values<0.05). CONCLUSION: Incorporating personalized 3D printed models in PCNL surgery has been shown to enhance the patients' comprehension of renal stone features and PCNL procedure. It also increases postoperative satisfaction.
