How to Use Phimostop
Phimostop is a medical device designed to treat phimosis (tight foreskin) in a progressive and non-invasive way. The treatment is based on the gradual use of tuboids with increasing diameters, helping to improve the elasticity of the foreskin without the need for surgery.

Instruction for use
- 1. Select the appropriate tuboid: choose the tuboid that best fits your condition, ensuring it can be applied without causing pain or excessive pressure.
- 2. Preliminary hygiene: before use, thoroughly clean the hands, the tuboids, foreskin, and glans.
- 3. Insertion: moisten both the tuboid and the foreskin to facilitate insertion.
Insertion of the tuboids
The tuboids are numbered from 1 to 22, each with an increasing diameter, allowing for the gradual expansion of the foreskin. Based on the severity of the phimosis, the appropriate cuboid should be selected

How to insert tuboids from 1 to 9:
- Gently pull down the foreskin as much as possible without forcing it.
- Insert one corner of the tuboid’s protruding base into the foreskin.
- Rotate the tuboid to insert it completely.
- Use the thumb and index finger to pull both the inner and outer foreskin up over the tuboid.
How to insert tuboids from 10 to 22:
- Gently pull down the foreskin as much as possible without forcing it.
- Position the base of the tuboid on the glans.
- Use the thumb and index finger to pull both the inner and outer foreskin up over the tuboid.
Securing the Tuboid
Lower the tuboid’s flaps and secure it to the penis by applying tape on both sides of the foreskin.
Duration of use
Each tuboid should be worn for at least 72 hours until an improvement is noticed, allowing progression to the next size. If the larger tuboid causes pain, it is recommended to return to the previous one and continue using it for at least another 72 hours.
Preventive use
For individuals prone to recurrent phimosis (e.g., due to diabetes), it is recommended to wear the most suitable tuboid periodically (e.g., one night per week) to maintain foreskin elasticity.
