Renal hilar tumors, especially those adjacent to renal arteriovenous and renal pelvis, pose a significant challenge in surgical treatment. In this case, a middle - aged male patient presented with a right renal hilar tumor. The proximity of the tumor to critical structures makes it difficult to achieve complete tumor resection while preserving renal function and the integrity of renal hilar structures. Robotic laparoscopic partial nephrectomy has emerged as a promising approach, but it requires high - level surgical skills and precision.

The patient underwent a comprehensive pre - operative evaluation, including imaging studies such as computed tomography (CT) and magnetic resonance imaging (MRI) to accurately assess the tumor's location, size, and relationship with surrounding structures. The robotic laparoscopic partial nephrectomy was performed using the da Vinci surgical system. During the operation, the surgical team carefully dissected the tissues around the renal hilum, identified and protected the renal arteriovenous and renal pelvis. The tumor was then resected with a margin, and the renal parenchyma was reconstructed.

The operation was successfully completed. The tumor was completely resected, and the renal hilar structures, including the renal arteriovenous and renal pelvis, were preserved. The patient's post - operative recovery was uneventful. There were no significant complications such as massive bleeding, urinary leakage, or renal function impairment. Follow - up imaging studies showed no signs of tumor recurrence, and the patient's renal function remained stable.

Robotic laparoscopic partial nephrectomy is an effective and safe treatment option for right renal hilar tumors, even when the tumor is close to the renal arteriovenous and renal pelvis. This approach allows for precise dissection and tumor resection while minimizing damage to surrounding critical structures. However, it requires a skilled surgical team and careful pre - operative planning. Further studies with larger sample sizes are needed to confirm these findings and optimize the surgical technique for better outcomes in patients with similar conditions.
