Abstract

Objective: To evaluate the safety and effectiveness of reverse suture technique during RLPN for dorsal lower pole renal tumors. Methods: A retrospective analysis of the clinical data of all patients with dorsal lower pole renal tumors underwent RLPN using reverse suture technique in our hospital from March 2015 to March 2020. All surgeries involved the reverse suture technique, following the same procedure: Reveal and block the renal artery with an artery clamp, completely remove the tumor, defects of the vascular and collecting system were repaired and the continuous reverse suture technique was used for suture of renal parenchyma. Variable analysis included operative time, blood loss, and warm ischemia time, and positive margin rate, length of hospitalization and perioperative complications. Results: Among the 11 patients, 6 were male and 5 were female. The average age was 56.8 ± 6.8 years old. The tumor diameter was 3.4 ± 0.6 cm. The warm ischemic time was 28.1 ± 5.8 min. All surgeries were successful without conversion to radical nephrectomy or open partial nephrectomy. The average estimated blood loss was 116.4 ± 29.1 ml. The mean operative time was 124.9 ± 28.5 min, the drain removal time was 4.4 ± 1.4 days, the average length of hospitalization was 8.3 ± 1.6 days, and all patients recovered well after the operation without major complications. Conclusion: The reverse suture technique is safe and effective for management of dorsal lower pole renal tumors during RLPN for selected patients.
