Outcome

Type Measure Description Time frame Safety issue
Other Cutaneous Injury Occurrence of cutaneous injury, such as erythema, blistering or rash occuring below the site of transducer placement 5 minutes after LOTUS intervention
Other Heart rate Heart rate will be measured at baseline, during LOTUS intervention, and immediately after LOTUS intervention has ended. Baseline and 15 minutes after start of Intervention, and 5 minutes after end of intervention.
Primary Glomerular Filtration Rate (GFR) Absolute change in glomerular filtration rate, GFR, measured by Tc-99m DTPA (diethylenetriamine pentaacetic acid) imaging (Gates Method) in the treated kidney(s) from baseline to during LOTUS Baseline and 15 minutes after start of Intervention
Secondary Percent change in GFR Percent change in GFR in the treated kidney(s) from baseline to during LOTUS. Baseline and 15 minutes after start of Intervention
Secondary Blood Pressure Blood pressure is measured at baseline, during LOTUS intervention, and immediately after LOTUS intervention Baseline and 15 minutes after start of Intervention, and 5 minutes after end of intervention
