Abstract

Objective To explore risk factors and development of upper urinary tract lithiasis in young soldiers by assessing the relevance between serum electrocyte, routine urine test. Methods 255 young soldiers suffered from upper urinary tract lithiasis were involved in this research. Other 377 health young soldiers were considered as control. Serum levels of K, Na, Cl, Ca, CO2-CP, and urine pH and urine specific gravity (SG) were analyzed between these two groups. Results There was significant difference in serum K, Na, Cl, Ca, urine pH, and SG. Logisitic regression analyses showed that K and urine pH were protective factors, while Na, Ca, and SG were risk factors for upper urinary tract lithiasis in young soldiers. The risk equation was established by logistic regression:Y=exp(-140.56-1.91×K+0.36×Na+4.25×Ca1.59×pH+92.72×SG)/[1+exp(-140.56-1.91×K+0.36×Na+4.25×Ca-1.59×pH+92.72×SG)]. Conclusions Serum K, Na, Ca, and urine pH and SG may play role in pathogenesis of upper urinary tract lithiasis, and the use of risk equation may contribute to preventing and curing this disease with individualized pattern.
