Frequently asked questions about the product mediNiK®.

mediNiK® solves the problem of residual stone fragments during endoscopic removal (URS) of renal stones, which can lead to new stone formation. Both hydrogel components bind residual stones within seconds. The stone fragments bound by the gel can then be effectively and quickly removed by the grasping methods used in flexible URS.

In combination with stone retrieval basket:
By removing significantly more kidney stone fragments < 1 mm than conventional ureteroscopy, mediNiK® can reduce the risk of stone recurrence by minimizing residual fragments that can serve as nuclei for new stone formation.

In combination with suction:
Fragment removal with FANS alone can be challenging in difficult-to-reach areas, such as the lower renal calyx. Larger fragments may require further fragmentation to allow efficient aspiration, and excessive negative pressure may pose a risk of mucosal injury. mediNiK® complements FANS by capturing stone fragments within a hydrogel and facilitating their removal, including from difficult-to-reach areas. Larger fragments can also be aspirated within the hydrogel, reducing the need for extensive dusting and shortening laser time.

Depending on the type and size of the renal stone, more than 1000 small fragments can be removed by mediNiK® during a single operation.

No. The certification of mediNiK® is currently valid only for use as part of URS.

The unique hydrogel does not stick to surfaces. However, it may become trapped e.g. in the extraction basket, even when this is open. To prepare the extraction basket for the next retrieval procedure, we recommend wiping off the hydrogel on a coarse sterile gauze.

Yes, mediNiK® is a medical product based on natural raw materials. Almost all the raw materials in the two components - K1 (basic substance) and K2 (activator) - are found in everyday foods and medical products. Its biological safety has been proven in studies in accordance with DIN EN ISO 10993.

The data obtained to date regarding the use of mediNiK® in patients do not indicate any allergic reactions due to administration of the hydrogel. If there are any indications of an allergic reaction after using mediNiK® , you should consult a doctor immediately.

mediNiK® is intended for professional use only and can therefore not be obtained outside the medical field. Healthcare professionals can obtain the product from FARCO-PHARMA GmbH.
