Abstract
- Objective : to assess safety of left renal vein (LRV) ligation during circular resection of the inferior vena cava in right-side kidney carcinoma with tumor venous thrombosis. Materials and methods . We selected medical data of 63 renal cell carcinoma patients with tumor venous invasion undergone nephrectomy, thrombectomy, IVC resection with LRV ligation (Group 1; n = 29 (46.0 %)) or preservation of venous outflow from the contralateral kidney (Group 2; n = 34 (54.0 %)). Median age of study participants was 56.0 + 8.8 years (range: 32—72 years); a male to female ratio was 1:1.9. Such parameters as age, gender, median glomerular filtration rate (GFR), stages of chronic kidney disease (CKD), blood loss, and duration of surgery were comparable across the two groups ( р >0.05 for all parameters). Median follow-up was 32.8 months (range: 1—226 months). Results. We observed no significant changes in median GFR in the late postoperative period compared to baseline among patients with ligated LRV (65.7 vs 71.2 mL/min/1.73 m2; р >0.05) and patients with preserved venous outflow from the contralateral kidney (60.6 vs 68.4 mL/min/1.73 m2; р >0.5). Patients that underwent LRV ligation were less likely to have reduced GFR compared to those with normal contralateral renal venous outflow (34.5 % vs 44.1 %; p >0.05). However, participants with ligated LRV had CKD upstaging (from stage 0—I to stage I—II) more frequently than participants with preserved venous outflow (27.6 % vs 5.9 %; р = 0.022). None of the patients developed stage III CKD after LRV ligation. Conclusion . LRV ligation during circular resection of the IVC in right-side renal cell carcinoma patients with tumor venous thrombosis does not lead to a clinically significant decrease in long-term deterioration of renal function.
