I say, and with God's success: If urine splashes like the heads of needles on the garment or body, it is excused due to necessity, even if the garment becomes full, as long as one takes precautions as much as possible; because it is not possible to avoid it, thus its ruling is lifted. See: Tabyin al-Haqaiq 1: 75, and Al-Wiqayah p. 132, and God knows best.
