目的:总结从化地区复杂性肾结石晶体化学成份特点,为预防其复发提供依据。方法:检测从化地区95例复杂性肾结石患者的结石晶体的化学成份,同时分析患者的相关临床资料。结果:本组95例复杂性肾结石患者中,结石晶体为混合成份91例(95.8%),其中草酸钙+磷酸钙47例(49.5%)、草酸钙+尿酸7例(7.4%)、草酸钙+磷酸钙+尿酸9例(9.5%)、草酸钙+磷酸钙+磷酸镁铵25例(26.3%)、草酸钙+磷酸钙+胱氨酸3例(3.2%);结石晶体为草酸钙成份4例(4.2%)。结论:从化地区复杂性肾结石以混合成份为主,应加强病因诊断并采用针对多种病因的积极的复发预防性治疗。
OBJECTIVE: To summarize the characteristics of chemical composition of complex renal calculus in Conghua area, and to provide basis for prevention of recurrence. Methods: The chemical composition of stone crystals in 95 patients with complex renal calculi in Conghua area was analyzed. The clinical data of patients were also analyzed. Results: Of the 95 patients with complex renal calculus, 91 (95.8%) were stone crystals, of which 47 were calcium oxalate and calcium phosphate (49.5%), 7 were calcium oxalate and uric acid (7.4% 9 cases (9.5%) of calcium + calcium phosphate + uric acid, 25 cases of calcium oxalate + calcium phosphate + magnesium ammonium phosphate (26.3%), 3 cases of calcium oxalate + calcium phosphate + cystine (3.2% 4 cases (4.2%). CONCLUSIONS: The complex renal calculi in the Conghua area are dominated by mixed ingredients. Etiologic diagnosis should be strengthened and aggressive relapse prophylaxis for multiple etiologies should be used.
