Abstract

Abstract:

Objective

To evaluate the efficacy,safety and cost of electronic flexible ureteroscopy lithotripsy (FURS) and mini percutaneous nephrolithotomy lithotripsy (PCNL) in the treatment of 2~3 cm pelvic calculi.

Methods

Fifty six patients with single pelvic calculi (2~3 cm) were treated in Zhangjiagang Traditional Chinese Medicine Hospital from January 2015 to August 2016. 32 cases in flexible ureteroscopy group, and 24 cases in mini percutaneous nephrolithotomy group. The operative time, stone-free rate, blood transfusion, postoperative procalcitonin and CRP, rates of complications, hospitalization time after operation, overall expenditure were compared between the two groups

Results

The operative completion rate of FURS group was 93.8%(30/32), and 100% in PCNL group; the stone-free rate of FURS was 90.6%(29/32), and 91.7%(22/24) in PCNL group, procalcitonin were (0.9±0.2) μg/L and (0.8±0.1) μg/L; CRP were (19.6±0.3) mg/L and (17.1±0.2) mg/L; incidences of complications were 3.1%(1/32) and 16.7% (4/24). And differences between the two groups mentioned above were not statistically significant (P>0.05). The operative time of FURS and PCNL were (98±2) min, and (54±8) min respectively, hospitalization time after operation were (5.1±1.6) d and (9.3±1.7) d respectively; total cost were (3.3±0.6) and (2.5±0.8) ten thousand yuan respectively; the differences were statistically significant (P<0.05).

Conclusion

Compared with PCNL, FURS can be the first choice in treating solitary pelvic stone (2~3 cm).
