Rigid ureteroscopy, a neglected choice for stent removal: a randomized controlled trial to compare rigid ureteroscopy, flexible cystoscopy, and rigid cystoscopy

Abstract

After patients arrived at the hospital, data collection staff collected their baseline information, including age, height, weight, phone number, and reason for stent placement, and then used visual analog scale (VAS) scores to assess the baseline pain situation, which is a 10-cm ruler and the observer indicates his/her pain level by making a mark. [...]a total of 150 patients were included in this study, and all patients participated in follow-up telephone interviews. In different groups, no significant differences were discovered in age, male to female ratio, body mass index, disease composition, or VAS score [Supplementary Table 1, http://links.lww.com/CM9/B155]. [...]statistical analysis was performed on the hematuria days of each group.
