In all patients, 24-h pad test using Kitchen scale with accuracy of 1 g weight of total number of pads used by patients for 24 h was done and pad weight difference (post soakage weight- pre soakage weight) was taken in all cases. Incontinence was graded as follows:
Mild incontinence: 24 h leak1.3–19 g
Moderate incontinence: 24 h leak20–74 g
Severe incontinence: 24 h leak75 g or more
Vitamin D (serum 25 0H D) levels were measured by electrochemiluminescence immunoassay (ECLIA) using Roche Elecsys 2010 immunoassay analyser and in the Department of Endocrinology, AIIMS, New Delhi. Patients were divided as follows:
Vitamin D levels >30 ng/ml: Sufficient
Vitamin D levels 20–30 ng/ml: Insufficient
Vitamin D levels <20 ng/ml: Deficient
Correlation of vitamin D was made with different grade of SUI as per ISI grading and pad test.
