This multi-institutional study revealed that elevated pre-NLR was significantly associated with worse pathological features such as tumor grade 3, advanced pT stage, positive LVI, and lymph node involvement in RNU specimens, and elevated pre-NLR was an independent risk factor of disease recurrence and cancer-specific mortality in UTUC patients treated with RNU.

High visceral fat area was a positive predictive biomarker for better recurrence-free survival after curative surgeries for localized clear cell renal cell carcinomas; however, body mass index was not a predictor.

Serum Krebs von den Lungen 6 was elevated compared with baseline in all cases with interstitial lung disease. Some patients who developed mild interstitial lung disease during everolimus treatment could continue to receive the treatment. Even when severe interstitial lung disease developed, withdrawal of the drug and short-term use of high-dose steroids resulted in rapid recovery. Prompt recognition of interstitial lung disease exacerbation as well as exclusion of progressive disease or infection is of primary importance.

Using UBS prevents suture slippage and enables tieless anastomosis. VUA using a UBS may relieve surgeon stress because a rapid and secure anastomosis is achievable.
