They were  prospectively randomized into 2 groups .Group I  receive 10 ml of  2% lidocaine hydrochloride gel at 4 ◦C and Group II receive 10 ml of  2% lidocaine hydrochloride gel at room temperature (22 ◦C). After instillations of the gel and at the end of cystoscopy the patients were immediately asked to score the pain level using a NUMERIC RATING SCALE (NRS) FOR PAIN</p> <p><strong>Result:</strong> A total of 70 male patients were enrolled in the study then were randomized into 2 groups . No significant differences in patient age and numbers of previous cystoscopy between the two groups . The pain scores were analyzed using the Mann-Whitney U test. Pain perception scores during gel instillation were not statistically different between the groups ( P= 0.496 ). Pain perception scores during cystoscopic procedure in group I were statistically lower than in group II (<em>P < </em>0.05) </p> <p><strong>Conclusion: </strong>Transurethral cooled  2% lidocaine gel significantly reduced the pain during cystoscopy  when compare  with instillation of  room temperature 2% lidocaine hydrochloride .But did not significantly reduce pain perception score during gel instillation</p>}, number={2}, journal={Insight Urology}, author={Chansirirattanakul, Thongchai and Thaidumrong, Tanet and Choonhaklai, Vorapot and Chittchang, Viroj and Pumpaisanchai, Somkiat and Wongwattanasatien, Nattapong and Sindhubodee, Sermsin and Kosrisirikul, Chawawat and Huabkong, Matchima and Duangkae, Somjith}, year={2018}, month={Dec.}, pages={28–34} }
