Core Tip

Core Tip: Ureteral stents are commonly used in urology and with appropriate care, it is considered a safe and easy procedure to manage ureter obstruction. However, due to multiple factors, its removal may be delayed which can result in stent calcification and infection. Even longer prolongation can lead to renal function decrease and parenchymal thinning from long-term obstruction which may require invasive procedures such as nephroureterectomy. Research on new stent material and specialized medical recordings dedicated to tracking stented patients are a few of the many ways that have been devised to prevent complications. Most importantly, thorough medical follow ups and detailed patient education is necessary in all cases to ensure the patients’ safety.
