Abstract:
To analyze types of urinary calculi and patients' clinical characteristics, and to explore the strategies for prevention and treatment of urinary calculi.
Methods: A total of 1 849 patients with urinary calculi were treated in the Department of Urology, the Third Xiangya Hospital of Central South University. The components were analyzed by infrared spectroscopy. The relationship between stone composition and clinical parameters was analyzed according to the clinical characteristics of the patients.
Results: The proportion of calcium oxalate stone or uric acid stone in male (84.1% or 7.7%) was higher than that in female (78.4% or 4.2%). The older patients were more likely to be diagnosed as uric acid stone. The proportions of uric acid stone in patients <18 years old, 18-<41 years old, 41-<66 years old, and ≥66 years old were 0.0%, 1.6%, 6.6%, and 12.4%, respectively. There was no significant difference in the proportion of stones in patients with different BMI. There were no significant difference in the stone composition between the patients with or without urinary tract infection, hypertension or diabetes. The proportion of uric acid stones in patients with acidic urine was higher than the other types. The proportion of uric acid stones in patients with elevated creatinine (12.1%) was higher than that in the patients with normal creatinine (4.5%).
Conclusion: Elderly patients, or patients with high uric acid and renal insufficiency are more prone to uric acid stones. Regulation of urinary pH may be an important strategy for preventing and treating urinary calculi in Hunan Province.
