ABSTRACT
Objective To explore clinical application of neotype controllability artificial nephrohydrosis in percutaneous nephrolithoto-my. Methods 400 patients with renal lithiasis or superior segment ureter lithiasis in our hospital were divided into group A and group B. 200 cases of group A received neotype controllability artifiicial nephrohydrosis;200 cases of group B received conventional artificial nephro-hydrosis. The puncture duration, amount of bleeding and times of puncture of the two groups were compared. Results 195 cases in Group A were developed renal tract for PCNL effectively,157 cases were developed renal tract for PCNL effectively in Group B. The puncture duration, amount of bleeding and times of puncture of group A and group B were respectively (1. 8 ± 0. 7) vs. (2. 5 ± 1. 2) min,(112. 7 ± 51. 0) vs. (270. 2 ± 89. 3) mL,(1. 1 ± 0. 2) vs. (1. 8 ± 0. 7) times. The differences were significant. Conclusion Neotype controllability artificial nephrohydrosis can develop renal tract for PCNL effectively.
