The goal of this clinical trial is to compare the Kosmos Automatic Bladder Volume to the manual annotated bladder volume in participants across gender (male and female), age (children ages 7-17 and adults 18-89), and BMI strata (low to normal and high BMI). The hypothesis it aims to evaluate is: The Pearson correlation coefficient between Kosmos estimated bladder volume and manually annotated bladder volume will yield more than 0.90.

Participants will:

• Have their full bladders scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System by both a nurse and sonographer.
• Participants will void and measure their urine volume.
• Participants empty bladders will be scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System again by both a nurse and sonographer.
• Three sonographers will manually annotate the pre- and post-void exam images for each patient to calculate the manually annotated bladder volume.

Inclusion Criteria:

• Read and sign an English consent form, or assent form, in the case of a minor child

• Read and complete an English demographic and general health survey, or have an LAR complete it for them in the case of a minor child

• Give consent for participation, or assent in the case of a minor child

• Able and willing to comply with study requirements

• Follow fluid consumption requirements prior to the study visit

• Those aged 7 years through 89 years, healthy as well as individuals with pelvic region abnormalities (if applicable), including but not limited to:

  i) Bladder cancer ii) Thickened bladder wall iii) Bladder stones iv) Current bladder or urinary tract infection

Exclusion Criteria:

• Adults over 89 years old
• Children under the age of 7
• Persons who are pregnant
• Persons who report an empty bladder upon arrival at their scheduled study visit
• Children in foster care, as a foster parent may not legally consent for a foster child
• Those who cannot or refuse to sign their consent or assent (including those with an LAR willing to provide consent)
• Those who cannot provide informed consent or whose LAR cannot provide consent
• Those who cannot speak or read English
• Participants from ECHO-010 Bladder AI Training and Validation Data Collection Study
