ABSTRACT
BACKGROUND:
Renal function after left renal vein (LRV) ligation following en bloc resection of segmental inferior vena cava (IVC) and right kidney is understudied. We assessed the impact of LRV ligation on postoperative renal function following en bloc resection of segmental IVC and right kidney.METHODS:
We retrospectively reviewed 28 patients who underwent LRV ligation during en bloc resection of segmental IVC and right kidney. Patient demographics, tumor characteristics, intraoperative factors, complications, length of hospital and intensive care unit (ICU) stay, and patient survival were collected. Pre- and postoperative renal function was retrospectively analyzed.RESULTS:
Twenty patients underwent robot-assisted surgery and eight patients underwent open surgery. The median operative time was 162 min and estimated blood loss was 350 mL. Ten patients had normal renal function and 12 patients had an initial increase in creatinine but improved gradually. Six patients developed acute renal failure; five patients gradually recovered in 5-32 days after temporary hemodialysis. Renal replacement therapy significantly correlated with maximal anterior-posterior diameter of the LRV (p = 0.001). Complications were observed in 11 cases, four of which were Clavien-Dindo grades I-II. Thirteen patients were alive with no recurrence, nine patients were alive with metastasis, and six cases died during the follow-up period.CONCLUSIONS:
LRV ligation following en bloc resection of segmental IVC and right kidney is feasible, with no significant long-term impact on renal function. The maximum anterior-posterior diameter of the LRV is a reliable method for predicting renal replacement therapy in the absence of collateral circulation.Key words
