Definition of Risk Factors
Demographic information, comorbidities, medication histories,
biochemical profiles, reports of urodynamic testing and surgical
procedures were collected from the CMUH–CRDR. Comorbidities of diabetes
mellitus, hypertension, cardiovascular diseases, psychosis, menopausal
syndrome and constipation were defined by the International
Classification of Diseases, 9th/10thRevisions, Clinical Modification (ICD-9-CM and ICD-10-CM) codes, and
medication histories for hypertension, diabetes, and hormone replacement
therapy (HRT) were recorded within 1 year before the index midurethral
sling surgery (Supplementary Table 1 ). Biochemical profiles of
blood glucose, liver function, renal function, and complete blood count
were obtained within 1 year prior to the index procedures. Reports of
urodynamic testing, such as uroflowmetry information and urethra
pressure profiles, were obtained within 3 years prior to the index
procedures. Surgical information extracted from the operation database
included length of operation, American Society of Anesthesiology (ASA)
score, wound contamination classification, anesthesia type, and sling
type.
