Other Mechanical Complications of Indwelling Ureteral Stent

Indwelling ureteral stents are commonly used in urologic surgeries to maintain the patency of the ureter and facilitate the drainage of urine from the kidney to the bladder. While these devices are generally safe and effective, they can also lead to a variety of mechanical complications that may require additional intervention.

1. Migration: One of the most common complications of indwelling ureteral stents is migration, which occurs when the stent moves out of its intended position. This can cause discomfort, pain, and obstruction of the urinary tract. In severe cases, migration may require surgical removal of the stent.
2. Fracture: Ureteral stents are designed to be flexible and resilient, but they can still fracture or break under certain conditions. This may occur if the stent is subjected to excessive tension or compression, or if it becomes twisted or kinked. Fractured stents may cause irritation, infection, or obstruction, and may require replacement or removal.
3. Encrustation: Indwelling ureteral stents can become encrusted with minerals and other substances found in urine, particularly in patients with a history of urinary tract infections or metabolic disorders. This can lead to blockage, infection, and discomfort, and may require removal of the stent.
4. Perforation: In rare cases, indwelling ureteral stents can perforate the ureter or bladder, causing pain, bleeding, and infection. This may occur if the stent is inserted too deeply or if there are underlying anatomical abnormalities. Perforated stents require surgical intervention to repair the damage.
5. Compression: Ureteral stents can compress surrounding tissues and structures, leading to nerve damage, blood vessel compression, or other complications. This may occur if the stent is inserted too tightly or if it becomes twisted or displaced. Compression can cause pain, numbness, or other sensory or motor deficits.

If you are experiencing any discomfort or complications related to an indwelling ureteral stent, it is important to seek medical attention promptly. Your doctor can evaluate your condition and recommend appropriate treatment, which may include stent replacement or removal, medication, or other interventions.

Remember, while indwelling ureteral stents are generally safe and effective, they can also lead to various mechanical complications. By staying aware of the potential risks and seeking prompt medical attention when necessary, you can help ensure the best possible outcome for your urologic health.
