1.Weigh the clean urine pad and record the weight before the examination; 2.Please empty your bladder and put on the urine collection pad; 3.Steps of the examination: (1) Drink 500ml of sodium-free liquid within 15 minutes; (2) Walk for half an hour, including climbing up and down a flight of stairs; (3) Do the following tests for the rest of the time: ①Stand up from your seat 10 times; ②Cough hard 10 times; ③Run in place for 1 minute; ④Bend down and pick up small objects on the ground 5 times to pick up small objects on the ground; ⑤ wash hands under running water for 1 minute. 4.If the pad is wet, please remove the pad and replace it with a new one. 5.Please avoid urinating on your own during the examination, and delay urination as much as possible if you have an urge to urinate. 6.If you have to urinate during the examination, the examiner will record the duration of the examination and the volume of urination. and schedule you for another test as needed; 7. At the end of the test, remove the collection pad and drain the urine into the collection device as instructed; 8. Record the amount of urine voided and weigh the pad; 9. Weigh the pad in grams at the end of the one-hour pad experiment, subtracting the weight of the clean pad. Record the weight grams of leaking urine (1 gram is equivalent to 1 ml of urine). Judgment of the results: ① urine pad weight gain >1g is positive; ② pay attention to the presence of weighing errors, sweating and vaginal secretions when the urine pad weight gain >2g; ③ urine pad weight gain <1g suggests basic dryness or experimental error. Mild incontinence: 1h leakage ≤ 1g; moderate incontinence: 1g < LH < span> leakage < 10g; severe incontinence: l0g ≤ 1h leakage < 50g; very severe incontinence: 1h leakage ≥ 50g. Caution: weight equal to 1g maybe due to weighing error, sweating or vaginal discharge; fecal incontinence should be considered and weight corrected.
