A uroscopy flask, also known as a "matula", is a piece of transparent glass – this is imperative as colorations, along with any deformations, in the glass may lead to a misdiagnosis – that is circular at the bottom, while there is a thin neck at the top, and an opening for the patient to urinate in.

The temperature at which the urine is examined is a very important factor to consider in the process of uroscopy. When a patient urinates, the urine will be warm, so it is necessary for it to stay warm for proper evaluation. The external temperature should be the same as the internal temperature.

Another problem with urine cooling is that it would become thicker. The longer that it had to cool down the more likely it was that the crystals in it would bond together, causing it to thicken. This could lead to a false diagnosis, that is why doctors usually inspected the urine quickly.
