Challenging Cases of Renal Cell Cancers With or Without Tumor Thrombus During the Covid-19 Pandemic.

ABSTRACT

BACKGROUND/AIM: Large or bilateral multiple renal cell carcinoma (RCC) without/with tumor thrombus (TT) in the renal vein (RV) or inferior vena cava (IVC) poses a challenge to the surgeon due to the potential for massive hemorrhage, tumor thromboemboli and dialysis, and the situation is more critical due to Covid-19 pandemic. We report our experience and measures in dealing with challenging cases of large or multiple RCCs without/with TT during the ongoing Covid-19 pandemic. PATIENTS AND METHODS: Between 4/2020-10/2020, five patients underwent RCC resection with/without TT. Patients 1 and 2 had RCCs/TT in RV; Patient 3 had RCC/TT supradiaphragmatic below right atrium; Patient-4 had a 26 cm RCC; Patient-5 had multiple RCCS as part of Birt-Hogg-Dube syndrome. RESULTS: Patients were preoperatively tested negative for Covid-19. Operation times were 105, 85, 255, 200 and 247 minutes for Patients 1-5. Estimated blood loss was 100, 50, 3,900,100 and 50 ml, respectively. Patient 3 underwent RCC resection en bloc with IVC/TT. Patients 1 and 2 underwent resections of RCC/TT in RV. Patient 4 underwent a 26 cm RCC resection. Patient 5 underwent laparoscopic bilateral radical nephrectomies. No immediate postoperative complications were reported. CONCLUSION: We successfully managed 5 challenging cases of RCCs despite the recommendations imposed by hospitals due to Covid-19 pandemic, with favorable outcomes.
