Methods: Patients with upper ureteral calculi who received lithotripsy in Pengzhou Hospital of Traditional Chinese Medicine between February 2015 and March 2017 were selected and randomly divided into two groups;RIRS group received combined retrograde intrarenal surgery and the Mini-PCNL group received mini-percutaneous nephrolithotomy. 3 d after surgery;the contents of liver and kidney function indexes and stress hormones in serum as well as the expression of CD4+T cell transcription factors in peripheral blood were measured. Results: Serum ALT;AST;γ-GT;BUN and Cr contents of RIRS group 3 d after surgery were not significantly different from those of Mini-PCNL group;and HO-1;ET-1;ACTH;Cor and YKL-40 contents in serum as well as RORγt and T-bet mRNA expression in peripheral blood were significantly lower than those of Mini-PCNL group while Gata-3 and Foxp3 mRNA expression in peripheral blood were higher than those of Mini-PCNL group. Conclusion: Combined retrograde intrarenal surgery for upper ureteral calculi activates less stress response and inflammatory response than mini-percutaneous nephrolithotomy.展开更多
