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 1.71 and 0.551 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 (AU)
