Abstract:
Objective To explore the application value of reserved guide wire in percutaneous nephrolithotomy (PCNL) for complex kidney calculi.
Methods From May 2014 to September 2017, 63 patients with complex kidney stones were evaluated in our hospital, including 34 cases of staghorn stones with a mean size of (4.8±1.8) and 29 with multiple stones. The distribution of kidney calculi was observed before the establishment of the channel. A guide wire was reserved and fixed, and then a percutaneous renal channel was established according to the reserved guide wire for PCNL.
Results The kidney calculi were completely removed by one-stage operation in 52 cases (82.6 %). Eleven patients underwent the second-stage operation with a total removal rate of 95.1%. The operation time was (83.5±40.8) min and the length of hospital stay was (8.2±3.7) d. No pleural, intestinal canal, liver and spleen injuries occurred. No blood transfusion and renal vascular embolism were observed.
Conclusion For patients with complex kidney calculi, the reserved guide wire can simplify the surgical procedures, accurately puncture the kidney calices, improve the calculi removal rate of PCNL and shorten the operation time, which is worthy of clinical promotion.
