The WaterWorks® Douching Device is indicated for the reduction or abatement of perceived vaginal odor with or without complaints of discharge in women with no infectious cause of vaginitis.
The Water Works® Douching Device is a reusable system consisting of a customized 32 ounce, water container, connecting hose and a stainless steel nozzle. A hose clamp for controlling water flow through the hose and a plastic loop to attach the container to a shower head are also provided. The container is filled with tepid tap water which flows through the hose to the nozzle. The water container is hung approximately 3 feet above the vagina (eye-level).
Here's a breakdown of the acceptance criteria and study details for the WaterWorks® Douching Device, based on the provided 510(k) summary:
Acceptance Criteria and Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Proportion of subjects meeting success criteria | WaterWorks® Group: 78% |
| (Implicit) No adverse effects on vaginal eco-system | Changes in lactobacillus score and Nugent Score were similar to the Control Group. |
| (Implicit) No significant increase in other adverse events | Other adverse events were similar in nature and frequency to the Control Group. |
Note: The document doesn't explicitly state numerical acceptance criteria for "no adverse effects" but rather compares the device's performance to the control group, implying that similar or better performance compared to the control satisfies this criterion.
Study Details
-
Sample size used for the test set and data provenance:
- The document states "A comparative, randomized, and blinded multicenter clinical trial." It does not explicitly state the total sample size for the test set; it only provides the proportion of subjects meeting the success criterion for the WaterWorks® Group (78%) and the Control Group (38.5%).
- Data provenance: Not explicitly stated, but clinical trials are generally prospective in nature. The country of origin is not mentioned.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the given text. Ground truth for clinical trials often involves clinical endpoints assessed by healthcare professionals, but the details of their role and number are absent.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This information is not provided in the given text.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No. This device is a physical douching apparatus, not an AI-assisted diagnostic or medical imaging device. Therefore, an MRMC study or AI-related effectiveness is not applicable.
-
If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done:
- No. As stated above, this is a physical device, not an algorithm. Standalone performance is not applicable.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "success criterion" for the clinical trial appears to be related to the "reduction or abatement of perceived vaginal odor with or without complaints of discharge." This suggests patient-reported outcomes or clinical assessment by healthcare providers based on pre-defined criteria.
- Adverse effects were quantified by changes in lactobacillus score and Nugent Score, which are objective laboratory/clinical measurements.
-
The sample size for the training set:
- This information is not applicable/not provided. The device is a physical product, not an AI model that requires a training set. The study described is a clinical trial to evaluate the device's performance directly.
-
How the ground truth for the training set was established:
- This information is not applicable/not provided. There is no "training set" in the context of this physical device's evaluation.

4. DEVICE DESCRIPTION
The Water Works® Douching Device is a reusable system consisting of a customized 32 ounce, water container, connecting hose and a stainless steel nozzle. A hose clamp for controlling water flow through the hose and a plastic loop to attach the container to a shower head are also provided. The container is filled with tepid tap water which flows through the hose to the nozzle. The water container is hung approximately 3 feet above the vagina (eye-level).
5. INTENDED USE
The WaterWorks® is indicated for the reduction or abatement of perceived vaginal odor with or without complaints of discharge in women with no infectious cause of vaginitis.
{1}------------------------------------------------
TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.
The WaterWorks® Douching Device is similar in design and method of operation the predicate device, Good Health Premium Fountain Style Personal Douche and Enema System. Both systems are gravity fed and intended to be filled by the user with tap water.
7. PERFORMANCE TESTING
A comparative, randomized, and blinded multicenter clinical trial of the Water Works and the predicate device demonstrated that the proportion of subjects in the WaterWorks® Group meeting the success criterion was 78 percent versus a success rate of 38.5 percent for subject in the Control Group. Fisher's exact test comparing the overall success proportions (78.0% for Water Works versus 38.5% for Control) rejects the null hypothesis of no difference at a significance level less that 0.0001. Adverse affects on the vaginal Eco-System were quantified by changes in the lactobacillus score and the Nugent Score according to pre-defined criteria. Results for the WaterWorks Group were similar to that of the Control Group. Other adverse events occurring in both Groups were also similar in nature and frequency.

Dear Ms. Robinson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
