Background: Tumor-infiltrating neutrophils and lymphocytes play essential roles in promoting or combating various neoplasms. This study aimed to investigate the association between tumor-infiltrating neutrophils and lymphocytes and the neutrophil-to-lymphocyte ratio in the progression of urothelial carcinoma. Methods: A total of 106 patients diagnosed with urothelial carcinoma were was. Pathological examination for tumor grade and stage and for tumor-infiltrating neutrophils, both CD4 and CD8+ T lymphocytes, as well as the neutrophil- to-lymphocyte ratio were evaluated. Results: The presence of neutrophils and the neutrophil-to-lymphocyte ratio correlated with high-grade urothelial neoplasms. In both low- and high-grade tumors, the lymphocytes increased during progression from a non-invasive neoplasm to an early-invasive neoplasm. CD8+ T lymphocytes increased in low-grade non–muscle-invasive tumors compared to non-invasive tumors. Additionally, there was a significant decrease in CD8+ T lymphocytes during progression to muscle-invasive tumors. Conclusions: Our results suggest that tumor-infiltrating neutrophils and CD8+ T lymphocytes have a significant effect on tumor grade and progression.

Purpose: To compare the safety and efficacy of xylocaine gel and ketorolac as opioid-sparing analgesia compared with pethidine for shock wave lithotripsy (SWL) pain. Materials and Methods: A single-blinded randomized controlled trial (RCT) was performed in 132 patients with renal and upper ureteral stones amenable to treatment with SWL. The first patient group received intravenous (IV) pethidine and placebo gel; the second group received IV ketorolac plus placebo gel; the third group received lidocaine gel locally plus normal saline IV. Stone disintegration was classified as none (no change from basal by kidney, ureter, bladder X-ray or ultrasound [US] imaging), partial (fragmented and >4-mm residual fragments), and complete (≤4-mm residual fragments). Stone disintegration was assessed by kidney-ureter-bladder X-ray and US imaging. Pain was evaluated by use of the Numeric Pain Rating Scale (NPRS). Results: The NPRS scores were highest in the xylocaine group at 10, 20, and 30 minutes (p=0.0001) with no significant difference between the ketorolac and pethidine groups, except at 10 minutes (p=0.03) and a near significant difference at 30 minutes (p=0.054) in favor of ketorolac. Results for stone disintegration (none, partial, and complete, respectively) were as follows: 25 (50.0%), 23 (46.0%), and 2 (4.0%) for pethidine; 19 (35.8%), 23 (43.4%), and 11 (20.8%) for ketorolac; and 26 (89.7%), 3 (10.3%), and 0 (0.0%) for lidocaine (p=0.008). Conclusions: Ketorolac is a safe and more effective alternative to morphine derivatives for SWL analgesia. Lidocaine gel should not be used as mono-analgesia for SWL.
