Improving quality of life since 1987

Urinary tract obstructions are debilitating illnesses causing pain, suffering and health risk to patients of all ages. Though some patients can be treated pharmaceutically, many are left with the dire choice between surgery and catheters both of which risk impacting their lives permanently through undesired side-effects, complications, discomfort and a dependency on medical attention.

Pnn Medical was founded in Denmark in 1987 with the mission of improving quality of life for people suffering from urinary tract obstructions by developing and bringing to market the most minimally invasive solutions causing fewest side-effects, least discomfort and lowest degree of medical dependency enabling patients to continue living their lives to the widest possible degree.

Pnn is an acronym for “primum non nocere” (first do no harm) – the Hippocratic oath sworn by medical graduates across the world to put patient welfare at the highest of priorities.
