Area of Science:

• Urology
• Surgical Technology
• Medical Imaging

Background:

• Laparoscopic partial nephrectomy (LPN) is a standard treatment for renal tumors.
• Complex renal tumors present surgical challenges, potentially leading to longer operative times and increased complications.
• Advanced imaging techniques are being explored to improve surgical outcomes.

Purpose of the Study:

• To evaluate the efficacy of three-dimensional visualization (3DV) imaging technology in improving outcomes for LPN in patients with complex renal tumors.
• To compare the results of LPN using 3DV preoperative planning and intraoperative navigation versus conventional 2D imaging.

Main Methods:

• A prospective randomized study involving 247 patients with complex renal tumors (RENAL score 7-9) was conducted.
• Patients were assigned to either a 3DV preoperative planning group (Group-A) or a conventional 2D imaging group (Group-B).
• All patients underwent retroperitoneal LPN, with Group-A utilizing 3D models for planning and navigation.

Main Results:

• Group-A demonstrated significantly shorter warm ischemia time (WIT) (20.81 vs. 27.72 min, P=0.001) and hospital stay (6.98 vs. 11.06 days, P<0.001) compared to Group-B.
• Reduced hemoglobin drop (10.19 vs. 16.32 g/L, P=0.001) and analgesic use (15.6 vs. 24.3 mg, P=0.003) were observed in Group-A.
• Faster ambulation (22.4 vs. 34.7 h, P<0.001) and flatus passage (28.1 vs. 41.3 h, P<0.001) indicated improved postoperative rehabilitation in the 3DV group.

Conclusions:

• Three-dimensional visualization (3DV) imaging technology significantly enhances precision and safety during LPN for complex renal tumors.
• 3DV imaging leads to reduced warm ischemia time, decreased blood loss, and accelerated patient recovery.
• The technology aids in preserving renal function and offers a superior approach for managing challenging renal masses.
