ZHAO Yihua,JIANG Xumin,HUANG Wei, et al. Application of establish standard percutaneous renal access by ultrasound-guided “improved one-step method” in percutaneous nephrolithotomy[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2014, 44(12): 913-916.
Abstract：Objective: To investigate the safety and efficacy of establishing standard percutaneous renal channel using ultrasound-guided “improved one-step method”. Methods: A total of 131 patients with urinary calculi underwent percutaneous nephroscope lithotripsy using ultrasound-guided “improved one-step method” to establish standard percutaneous renal channel in our department from April 2013 to July 2014. The operation process and results of 131 cases were now retrospectively analyzed. Results: Channel in one hundred and thirty-one patients through the “improved one-step” was success fully established, I period of single-channel was establisbed in 122 cases, dual-channel in 8 cases, three-channel in 3 cases and II stage of new channel in 1 case, the time for setting up a single channel was 6 minutes on average. In the process of establishing channel, expanded too deep in 5 cases, including the upper urinary tract perforation in 3 cases and contralateral renal parenchyma injury in 2 cases. None of the patients suffered from severe loss of blood or destruction of adjacent organs during intraoperative or postoperative. Conclusion: As a technology of establishing standard percutaneous renal channel, it is safe and convenient and effective, which is worth of clinical promotion.
