• Resumen

  • Background: This study aimed to investigate the prevalence of urolithiasis and its association with systemic diseases among inpatients in a top hospital of China.

    Methods: This cross-sectional study included all inpatients in Peking Union Medical College Hospital (PUMCH) from 1 January 2017 to 31 December 2017. Patients were divided in two groups, the urolithiasis group and non-urolithiasis group. Subgroup analysis according to payment type (General or VIP ward), hospitalization department (surgical or not) and age was performed with patients in the urolithiasis group. Additionally, Univariable and multivariable regression analyses were performed to determine factors associated with urolithiasis prevalence.

    Results: 69518 hospitalized cases were included in this study. The age was 53.40 ± 15.05 and 48.00 ± 18.12 years, and the male-to-female ratio was 1.7:1 and 0.55:1 in the urolithiasis and non-urolithiasis groups, respectively (p < 0.01). Among all patients, urolithiasis had a prevalence of 1.78%. The rate depending on payment type (5.73% versus 9.05%, p < 0.01) and hospitalization department (56.37% versus 70.91%, p < 0.01) were significantly lower in urolithiasis group compared to the non-urolithiasis. Urolithiasis rate also showed age differences. Female was independent protective factor of urolithiasis, while age, hospitalization in the non-surgical department and payment type of general ward were risk factors of urolithiasis (all p < 0.01).

    Conclusions: Gender, age, hospitalization in the non-surgical department and the socioeconomic status, specifically, the payment type of general ward, are independently associated with urolithiasis.
