Abstract
This study evaluated the efficacy and safety of 3D printing technology combined with percutaneous nephrolithotomy in the treatment of complex renal calculi. Ninety patients with complex renal calculi were randomly divided into a 3D printing group (45 patients) and a control group (45 patients). In the 3D printing group, a patient-specific 1:1 3D printing model was established based on the patient's thin-layer CT scanning data. A 3D printing model was used for preoperative communication between doctors and patients. Preoperative puncture training, channel design, residual stone prediction, and percutaneous nephrolithotomy were performed under the guidance of a 3D printing model and B-ultrasound. The control group was treated with the conventional B-ultrasound-guided puncture method. Results suggest that there was a statistically significant difference between the two groups (P < 0.05). The overall score of the doctor-patient communication objects in the 3D printing group was 19.32 ± 1.57 points, and in the control group, it was 14.51 ± 2.13 points. The operation time of the 3D printing group was 103.21 ± 13.49 min, and that of the control group was 126.12 ± 25.87 min. The calculi clearance rate of the 3D printing group was 96%, while that of the control group was 80%. The incidence of postoperative complications was 6.67% in the 3D printing group and 22.22% in the control group. Compared with traditional percutaneous nephrolithotomy, 3D printing technology combined with percutaneous nephrolithotomy can significantly enhance the effectiveness of doctor–patient communication, shorten operation time, reduce operation bleeding, improve the stone clearance rate, reduce the incidence of complications and shorten the length of hospital stay. The proposed method is thus a safe and effective method to treat complex renal calculi.

We evaluate the therapeutic effect of 3D printing combined with percutaneous nephroscopy in the treatment of complex renal calculi
PCNL has become the gold standard for the treatment of staghorn calculi, multiple renal calculi or lower calyceal calculi due to its advantages of less trauma, less bleeding, a high stone clearance rate and protection of renal tissue
Summary
Nephrolithiasis is a common disease affecting urinary tract, which seriously affects the renal function of patients. Percutaneous nephrolithotomy is commonly used in the clinical treatment of complex renal calculi, but there is a high risk of complications and a high incidence of bleeding and infection[4]. For simple renal calculi, compared with open operations, percutaneous nephroscopy has the advantages of minimum trauma, less bleeding and fewer c omplications[7]. Traditional B-ultrasound or X-ray guidance can be successfully completed, but for complex renal calculi, due to its complex operation and long operation time, the incidence of complications is h igh[8]. Been performed on this combination’s application to complex renal calculi. We evaluate the therapeutic effect of 3D printing combined with percutaneous nephroscopy in the treatment of complex renal calculi
