Abstract

Object: To evaluate the relationship between imaging characteristics of kidney stones and results of small tunnel percutaneous lithotripsy technique at Military Hospital 103. Research subjects and methods: Descriptive, longitudinal, nonrandomized study on 289 patients indicated for mini-PCNL at Military Hospital 103 from July 2017 to July 2019. Result: The stone-free rate gradually decrease with the size of the kidney stones, the stone-free rate is highest in the group with size L ≤ 3 (cm), with a rate of 94.02-100%. The overall treatment results of patients gradually decrease with the size of kidney stones, the best overall treatment results are in the group with size L ≤ 3 (cm) with a rate of 91.52-100%. The group of patients with 1 stone had the highest stone-free rate after surgery at 88.83%. The stone-free rate was highest in groups S0 and S1 with a rate above 99%. The group of patients with stones that do not overlap the image on the KUB film and are not distributed into small calyces has a higher stone clearance rate than the group of patients with stones that overlap the image and are distributed into small calyces. The level of radiopaque of the stone does not affect the stone-free rate. Conclusion: The size, number, location of the stones and the characteristics of the stones overlapped on the KUB film and distributed into small calyces are related to the success rate of the mini-PCNL technique.
