| 1 | Analysis of the effect of holmium laser flexible ureteroscopic intrapelvic drainage in the treatment of parapelvic renal cysts显示文摘Objective:To explore the efficacy,safety,and feasibility of holmium laser flexible ureteroscopic intrapelvic drainage in the treatment of parapelvic renal cysts.Methods:From September 2012 to February 2019,a total of 18 patients,aged from 28 to 62(meanstandard deviation[SD]:46.50±9.14)years,were diagnosed with parapelvic renal cysts and treated by holmium laser flexible ureteroscopic intrapelvic drainage.There were 10 males and eight females.All of the parapelvic renal cysts were unilateral,and two cases were complicated with pyelolithiasis.The diameters of the cysts ranged from 4.1 cm to 8.2 cm.Results:All the patients completed the operation successfully in one stage without conversion to open surgery;in two cases,it was difficult to find the cysts during the operation,and the localization was completed by B-ultrasound and percutaneous injection of methylene blue.The mean operative time was 33.89(SD:9.68;range:22-54)min,and the mean hospitalization time was 2.67(SD:0.91;range:2-5)days.Three months and 6 months of follow-up were performed after surgery.The cysts disappeared in 13(72%)cases,and the diameter of the cysts in five(28%)cases decreased by more than 50%.Conclusion:Holmium laser flexible ureteroscopic intrapelvic drainage in the treatment of parapelvic renal cysts is simple,safe,and effective,and can be used as the first choice for the treatment of parapelvic renal cysts. | Yuanshen Mao Wenfeng Li Jun Da Mingxi Xu Yiwei Wang Yufei Gu Weixin Pan Zhong Wang | 2023 | Asian Journal of Urology2023，10，2： | 0 |
| 2 | A novel spherical-headed fascial dilator is feasible for second-stage ultrasound guided percutaneous nephrolithotomy:A pilot study显示文摘Objective:In second-stage percutaneous nephrolithotomy(PCNL),because the hydronephrosis has been decompressed,the dilated renal pelvis has resolved and the space is small.Consequently,introduction of the tip of the Amplatz dilator can cause injury to the opposite side of the renal-pelvic mucosa.In this study,we report the experimental and initial clinical performance of a spherical-headed fascial dilator developed specifically for second-stage PCNL.Methods:The novel spherical-headed dilator was compared with existing tapered-headed dilators in configuration and in puncture resistance utilizing a static puncture test.Subsequently,a pilot clinical study was conducted during which patients scheduled to undergo second-stage PCNL from June 2019 to October 2019 in our center were enrolled.A typical ultrasound guided PCNL procedure was performed with the exception that the new spherical-headed fascial dilator was substituted for a tapered-headed one.Results:Experimentally,stab resistance against polyethylene film was significantly increased using the novel spherical-headed dilator compared to the traditional tapered-headed dilators(p<0.005).In the clinical study,the novel dilators were successfully introduced into the renal pelvis and passed down the collecting system in all eight second-stage PCNL cases.There were no cases of renal pelvic perforation or brisk hemorrhage nor need for transfusion. | Yiwei Wang Liheng Gao Mingxi Xu Wenfeng Li Yuanshen Mao Fujun Wang Lu Wang Jun Da Zhong Wang | 2021 | Asian Journal of Urology2021，8，4： | 0 |
