Summary

This study will test four different water-drinking plans in 20 healthy women to see which one gives the best bladder filling for a pelvic ultrasound. Participants will drink different amounts of water on different days, and researchers will measure bladder volume and comfort. The goal is to find a protocol that provides a full enough bladder for a clear image without causing discomfort.
