Ureteral Stents Market – Insights
Ureteral stents are small tubes inserted into the ureter to treat or prevent a blockage that prevents the flow of urine from the kidney to the bladder. Ureteral stents are flexible in nature and approximately 10 inches in length. The most common application of ureteral stents is the treatment of kidney stones. Other applications include stricture (abnormal narrowing of the ureter), and tumors pushing the ureter, leading to a blockage. Moreover, swollen, inflamed, or damaged ureteral tubes in need of healing can have a stent placed to keep the kidney draining during the healing process.
The global ureteral stents market size was valued at US$ 492.6 million in 2017 and is expected to witness a CAGR of 5.7% over the forecast period (2018 – 2026).

Increasing prevalence kidney related disorders is expected to drive the ureteral stents market revenue
Rising prevalence of urolithiasis worldwide owing to changes in lifestyle such as lack of physical activity and dietary habits is the major factor driving the ureteral stents market revenue. Urolithiasis is a common urologic problem and constitutes a significant burden on the health care system. According to the National Health and Nutrition Examination Survey (NHANES) 2003 report, the prevalence of urolithiasis has increased over the last three decades in the U.S. and projected to experience economic burden, with an additional value of US $1.24 billion per year by 2030.
Along with elderly and adult population, kidney stones also affect children of all ages. According to the Journal of Urology 2015 data, ureteral stent placement is the most common procedures performed in approximately 20% of children with stones. The weighted average annual cost of care for pediatric urolithiasis is US $220 million per year.
Urinary incontinence (UI) is also a significant health problem worldwide with increasing geriatric population rate. It has a large economic and social impact on individuals and nation. According to the European Urology 2012 report, the Epidemiology of Lower Urinary Tract Symptoms (EpiLUTS) reported relatively high UI prevalence rates of 13.3% for men and 30.3% for women in the United Kingdom, Sweden, and the U.S.
Ureteral Stents Market Restraints
Ureteral stenting is associated with various side-effects such as irritation on voiding, pain and haematuria. Complications such as stent dysfunction and clinically significant urinary tract infections are also regularly observed. In most cases there is bladder irritation, typically causing frequent and/or uncomfortable urination. According to a research study published in National Center for Biotechnology Information (NCBI) 2009, stent discomfort can vary from one patient to another, and is believed to affect more than 80% of patients.
Furthermore, biofilms have been suspected to be the main reason for stent obstruction, stent dysfunction and clinically relevant infections leading to premature or emergency stent changes, antibiotic treatment and hospitalization. Biofilms lead to irritation and inflammation of the urothelium, which can worsen the symptoms.
Ureteral Stents Market - Regional Insights
On the basis of region, the global ureteral stents market is segmented into North America, Latin America, Europe, Asia Pacific, Middle East, and Africa. North America and Europe are expected to foresee significant growth in 2026 owing to increased number of urological surgeries, increasing prevalence of kidney stones and presence of major industry players. According to a European Urology study of 2012, in the U.S., kidney stone affects 1 in 11 people, and it is estimated that approximately 600,000 Americans suffer from urinary stones every year.
Asia Pacific ureteral stents market is expected to grow at highest CAGR due to increasing obesity and diabetes patient population prone to kidney disorders and developing healthcare infrastructure in the region. According to a research study published in Current Science journal 2005 data, in India, nearly 12% of patient had urinary stones and out of which 50% may end up with loss of kidney functions.

Ureteral Stents Market - Competitive Landscape
Key players operating in the global ureteral stents market include Applied Medical, Allium Medical, Bard Medical, B.Braun, Boston Scientific, Cook Medical, Coloplast, Conmed Corporation, Optimed, Olympus America, Pnn Medical A/S, Taewoong Medical, Teleflex, Uromed, and Urotech. Manufacturers in the ureteral stents market are focusing on development of less expensive products causing lower side effects than the available ones. Product innovation also comprises to address specific causes of stent’s failure, especially biofilm formation and encrustation.
Ureteral stents play an important role in a wide range of situations where urinary drainage is needed. It is used in case of intolerable acute renal colic and obstructive pyelonephritis; safety indications following endoscopic procedures include, ureteral perforation or edema, steinstrasse, history of renal failure, and kidney transplant. Ureteral stents are made from silicone-based material and other materials such as polyethylene, polyurethane, and metal. These stents are available in a wide range of diameters and sizes and are selected on the basis of individual patient anatomy. Majority of ureteral stents have curled pigtail structures on either end, which reduce stent movement.
Increasing prevalence of obesity is considered a major risk factor for kidney stone development, which in turn propels demand for ureteral stents. According to the National Health and Nutrition Examination Survey (NHANES), in 2014, kidney stones affected nearly 8.8% of adults in the U.S. Majority of these patients ultimately require surgical intervention. Stent placement is common at the time of stone surgery, mainly in the setting of extracorporeal shockwave lithotripsy and ureteroscopy.
Ureteral stents are important for management of several urologic and non-urologic conditions, however, hematuria, pain, infections, and encrustation are common side effects associated with these stents. Moreover, presence of the stent can result in bladder irritation in short-duration detrusor contractions, leading to a transient rise in bladder pressure. Furthermore, ureteral stent opens the VesicoUreteric Junction (VUJ), allowing urine to reflux whenever the bladder pressure rises, for instance, during a spasm or voiding.
Furthermore, long-term use of stents is associated with infection and precipitation of some salts in the urine, which can lead to build-up of crystalline deposits on the stent surface. Encrustation can cause blockages of the ureteral system, which makes stent removal painful and difficult. These factors are expected to reduce patient adherence for the procedures including ureter stent placement, which in turn hinders growth of the ureter stents market. However, precautions such as timely monitoring of stent location, change if chronically indwelling and removal of stents when no longer needed can avoid any associated complications.
