FILLing Protocols for the Right Bladder Volume at the RIGHT Time (FILLRIGHT)

Summary

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?"

OTHER

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. Before ingestion of water, a suprapubic ultrasound examination will be performed to assess the bladder filling, and calculation of bladder volume using the standard formula (length × width × height × 0.52). During ultrasound examination, a self-assessment of urinary sensitivity using the Bladder Sensitivity Scale (BSS) will be conducted.

OTHER

Quantity B

Woman participants will drink 750 ml in 10 minutes. Before ingestion of water, an ultrasound examination will be performed to assess the residual post-void volume. Before ingestion of water, a suprapubic ultrasound examination will be performed to assess the bladder filling, and calculation of bladder volume using the standard formula (length × width × height × 0.52). During ultrasound examination, a self-assessment of urinary sensitivity using the Bladder Sensitivity Scale (BSS) will be conducted.

OTHER

Quantity C

Woman participants will drink 500 ml in 5 minutes. Before ingestion of water, an ultrasound examination will be performed to assess the residual post-void volume. Before ingestion of water, a suprapubic ultrasound examination will be performed to assess the bladder filling, and calculation of bladder volume using the standard formula (length × width × height × 0.52). During ultrasound examination, a self-assessment of urinary sensitivity using the Bladder Sensitivity Scale (BSS) will be conducted.

OTHER

Quantity D

Woman participants will drink 250 ml in 1 minutes. Before ingestion of water, an ultrasound examination will be performed to assess the residual post-void volume. Before ingestion of water, a suprapubic ultrasound examination will be performed to assess the bladder filling, and calculation of bladder volume using the standard formula (length × width × height × 0.52). During ultrasound examination, a self-assessment of urinary sensitivity using the Bladder Sensitivity Scale (BSS) will be conducted.
