ABSTRACT
Background:
Urologists still encounter challenges when it comes to the surgical management of tumors located on the posterior lip and posterior renal hilar region. We propose a trans-retro-peritoneal (TRP) technique to address the difficulties associated with posterior hilar tumors during retroperitoneal laparoscopic partial nephrectomy (LPN). Its efficacy was evaluated in a retrospective case-control study.Methods:
The patients with posterior hilar tumors (≤7 cm) that underwent retroperitoneal LPN were included. The TRP technique allowed the posterior hilar tumor completely visible by incising the ventral peritoneum and rotating kidney ventrally during retroperitoneal LPN, which was applied in 36 cases, while the conventional retroperitoneal LPN was performed in 22 cases. Perioperative data were analyzed to evaluate the efficacy of TRP-LPN.Results:
In TRP-LPN group, the TRP technique was successfully performed in all the patients without converting to open surgery or radical nephrectomy. The warm ischemia time was significantly shorter in TRP-LPN group than conventional LPN group (20.3 vs. 28.5 min, P<0.001). Furthermore, the mean estimated blood loss in TRR-LPN group was significantly less than that in conventional LPN group (86.5 vs. 90.9 mL, P<0.05). The mean operation time and recovery time of gastrointestinal function were similar between two groups. No severe complications occurred, and no positive surgical margin was found. The rate of Trifecta achievement was 50.0% (18/36) and 31.8% (7/22) respectively for TRP-LPN and conventional LPN (P=0.175). After mean follow-up of 21 months, no recurrence or metastasis occurred in all cases.Conclusions:
Our findings, as demonstrated by the Trifecta outcomes, support the feasibility and efficacy of TRP-LPN in managing posterior renal hilar tumors. This approach may be considered as an efficient option for surgical management of such tumors.
