8. juni 2026 opdateret af: University Hospital, Brest

FILLing Protocols for the Right Bladder Volume at the RIGHT Time

The goal of this clinical trial is to compare evaluation of oral hydration protocols for the right optimal bladder filling prior to pelvic ultrasound.

The main question it aims to answer is which quantity of water should patiente drink before a pelvic ultrasound.

Woman participants will drink 4 differents quantity of water over 4 differents days:

  • Quantity A : 1000 ml in 15 minutes
  • Quantity B : 750 ml in 10 minutes
  • Quantity C : 500 ml in 5 minutes
  • Quantity D : 250 ml in 1 minutes

The order of the hydration protocols will be randomized.

All procedures are performed in the same way:

  • Before ingestion of water, the patient should urinate band (the volumen will be measured) an an ultrasound examination will be performed to assess the residual post-void volume
  • The patiente drinks water and the time was collected

  • Every 5 minutes during the procedure :

    • A suprapubic ultrasound examination will be performed to assess the bladder filling and to calculate of bladder volume using the standard formula (length × width × height × 0.52)
    • The Bladder Sensation Scale (BSS) was collected.
  • When the score to BBS reaches 3, the procedure should be stopped and the patiente should urinate band (the volumen will be measured). Then a last ultrasound examination will be performed.

After each procedure, the patiente answer at this question: "On a scale from 1 (very poor) to 10 (excellent), how would you rate the acceptability of ingesting the required hydration volume?"

Andet: Quantity A

Woman participants will drink 1000 ml in 15 minutes.

Before ingestion of water, an ultrasound examination will be performed to assess the residual post-void volume.

Foranstaltningsbeskrivelse
Tidsramme
Bladder volume
Tidsramme: Inclusion

The cumulative duration, for each protocol, during which two conditions are met:

  • Bladder volume greater than 150 ml
  • Blader Sensation Scale (BSS) score ≤ 2 The BSS is a medical tool used to evaluate and quantify how a patient perceives bladder fullness. The scale typically ranges from 0 to 4 .

Each score represents what the patient feels at a specific moment:

0: No sensation - The bladder is empty, or the patient feels absolutely nothing.

  1. First desire to void - The patient feels the bladder is starting to fill, but it can easily be ignored for a long time.
  2. Normal desire to void - The usual feeling that prompts a person to go to the restroom. The urge can be postponed if the person is busy.
  3. Strong desire to void / Urgency - The bladder is full. The urge is strong and uncomfortable; it is becoming difficult to delay.
  4. Urgent / Painful desire to void - The urge is so intense that it causes discomfort, pain, or fear of leakage. The patient must go immediately.

Minimum time
Tidsramme: Inclusion

Inclusion
Bladder volume
Tidsramme: Inclusion

Absolute and relative difference between the actual urine volume and the ultrasound-estimated volume just before voiding at the end of the procedure, adjusted after ultrasound estimation of post-void residual urine.

Before ingestion of water, the patient should urinate band (the volumen will be measured) an an ultrasound examination will be performed to assess the residual post-void volume.

When the BSS score reaches 3, the procedure should be stopped and the patiente should urinate band (the volumen will be measured). Then a last ultrasound examination will be performed.
Inclusion
Acceptability for each protocol
Tidsramme: Inclusion
Cumulative acceptability score for each protocol on a scale from 1 to 10. Response to the question: "On a scale from 1 (very poor) to 10 (excellent), how would you rate the acceptability of ingesting the required hydration volume?"
