Abstract

Abstract:

Objective

To investigate the efficacy and safety of needle- perc nephroscope for treatment of renal calculi in pediatric patients.

Methods

From September 2019 to June 2020, 20 children with renal calculi were treated with needle-perc nephroscope and holmium laser lithotripsy under general anesthesia in our hospital. The operation time, postoperative hemoglobin decline, postoperative pain score, hospitalization time and complications were observed.

Results

Twenty two sides of 20 cases of renal calculi were successfully punctured, including 16 cases of single puncture, 4 cases of 2 times of puncture, and 2 sides of 3 times of puncture. The average operation time was (45±12) min, the average decrease of hemoglobin was (5.5±0.8) g/L, the average postoperative pain score was (3.5±0.5) points, and the average day of postoperative hospitalization was (3.7±0.9) d. There were 3 cases of Clavien grade I complications with renal colic and 2 cases of Clavien grade II complications with body temperature ≥38.0℃ after operation. No blood transfusion cases and no Clavien III complications occurred. The stone-free rate at one month was 86.36% (19/22).

Conclusion

Percutaneous nephrolithotomy with needle-perc nephroscope for the treatment of small renal calculi in pediatric patients is safe and effective, with high stone-free rate, low complications and short hospitalization time.
