Urological double-pigtail stents have been used for decades to facilitate the drainage of urine from the kidney to the bladder and to relieve pain caused by ureteral obstruction. It is seen by urologists as a simple and effective routine procedure. Despite this, the stents are poorly tolerated by the body, seriously affecting the quality of life of some patients. Several studies have cited bothersome symptoms such as urgency, dysuria, incontinence, haematuria, incomplete emptying and lumbar pain. Unfortunately, it is not always known what causes these symptoms, although it is widely cited that the material of the coil in the bladder irritates this organ.
For this reason, various efforts have been made over the years to prevent and treat these stent-related symptoms. By making various adjustments in the materials and coatings used, but also by looking at the effect of temperature on the stent, attempts have been made to find a solution to reduce the pain of the patient. While these changes have certainly added value, no decisive solution has yet been found.
That is why our manufacturer Rocamed has begun to rethink the design of the double-pigtail stent, as the double-curl shape has remained unchanged for years. Based on research showing that less material in the bladder could reduce patients’ discomfort and through close contact with urologists, they have developed a product that the market demanded; a stent with a curl at the top and a suture at the bottom. Replacing the lower portion of the double-pigtail stent with a 0.3 French suture showed a significant reduction in urinary symptoms. The JFil stent, as Rocamed has called the “pigtail suture stent” (PSS), represents a medical advance in the field of stent tolerance in the ureter.
Mayumana Healthcare sees the JFil stent as an important step in the further development of future stents.
