Abstract
Objectives:
T1 ventral renal hilar tumors (VRHTs) represent a very special type of tumor, for which laparoscopic partial nephrectomy (LPN) by the retroperitoneal approach is challenging. In this study, we report our surgical technique and Trifecta results.
Methods:
Renal rotation technique has been established for retroperitoneal laparoscopic partial nephrectomy (RLPN) for VRHTs in our institution. Trifecta was used as a composite outcome measure for assessing quality of PLPN using this technique. A retrospective analysis of RLPN cases in 12 patients with VRHTs was performed.
Results:
Mean tumor size was 3.4 cm and median R.E.N.A.L. score was 8 (range 7–9). Mean warm ischemia time was 23.1 minutes, suture time 28.1 minutes, estimated blood loss 139.2 mL, operation time 122.8 minutes, and median hospital stay was 4 days. Three patients (25.0%) had Clavien-Dindo grade I–II complications. Seven patients (58.3%) achieved Trifecta. Postoperative pathological examination showed renal cell carcinoma in all cases with negative surgical margin. A median follow-up of 7 months revealed no local recurrence or distant metastases.
Conclusions:
Our Trifecta outcomes demonstrate that RLPN with renal rotation technique is feasible, safe, and effective for moderately complex VRHTs. The short-term functional and oncologic outcomes are promising; however, long-term follow-up is needed.
