Patient demographics,<br>degree of hydronephrosis, tumor diameter from computed tomography, and pathologic report were collected. Data were analyzed to determine correlations.</p> <p><strong>Results:</strong>  In renal pelvic tumor, higher degree of hydronephrosis correlated with higher pT stage (p=0.022) but no significant difference was shown in ureteral<br>tumor (p=0.352). For tumor diameter in both renal pelvis and ureter, there were no correlations with pT stage (p=0.128 and p=0.625). For tumor location, higher pT stage was more common in renal pelvic tumors (p=0.001) and high tumor grade correlated with high pT stage (p=0.037).</p> <p><strong>Conclusion:</strong>  In this study, there was significant correlation between the preoperative degree of hydronephrosis and pT stage in renal pelvic transitional cell carcinomas; however, none was found in ureteric tumors. The reason may be that smaller ureteric lumen caused early symptoms, which concerned patients.</p>}, number={2}, journal={Insight Urology}, author={Amornporncharoen, Treerat and Wongwattanasatien, Nattapong and Choonhaklai, Vorapoj and Choonhaklai, Vorapoj and Chittchang, Viroj and Pumpaisanchai, Somkiet and Thaidumrong, Tanet and Sindhubodee, Sermsin and Kosrisirikul, Chawawat and Huabkong, Matchima}, year={2020}, month={Dec.}, pages={9–16} }
