Abstract Objective To investigate the effect of continuous suture of renal pelvis, renal parenchyma and renal capsule on wound suture after removal of renal pelvis tumor. Methods Four healthy male Chinese rural dogs were selected. After successful anesthesia, the operation was performed according to the human open kidney partial resection procedure. The sutures of the renal pelvis mucosa, submucosa, muscular layer and renal layer were sutured continuously. The operation time, intraoperative blood loss, arterial block time, postoperative recovery time, and perioperative complications were observed. Results The operation time of renal artery occlusion, local occlusion time, renal artery occlusion time and local occlusion time were (39.00±2.16), (37.50±4.30), (10.25±2.50), (8.45±1.81) min, respectively. The amount of bleeding in the renal artery block partial nephrectomy and suture was (54.50±4.21) mL, and the amount of hemorrhage during local partial nephrectomy and suturing was (57.50±9.58) mL. After the anesthesia waken up, they could move in place. The next day, they were given food and returned to normal after a week. Conclusion The operation time is short, the amount of bleeding is small, the recovery is fast, and there are no serious complications such as major bleeding and urinary leakage after operation. It effectively prevents and eliminates two common complications after partial nephrectomy, which lays a foundation for its clinical application.
