Ureteric Stent - Side Effects and Complications

Side Effects and Complications

The main complications with ureteral stents are dislocation, infection and blockage by encrustation. Recently stents with coatings, such as heparin, were approved to reduce infection and encrustation to reduce the number of stent exchanges.

Other complications can include increased urgency and frequency of urination, blood in the urine, leakage of urine, pain in the kidney, bladder, or groin, and pain in the kidneys during, and for a short time after urination. These effects are generally temporary and disappear with the removal of the stent.

Stents often have a thread, used for removal, that passes through the urethra and remains outside the body. This thread may cause irritation of the urethra. This may be increased for patients who were born with Hypospadias or other conditions that required a similar corrective surgery. Care must be taken to ensure that the thread is not caught or pulled, which may dislodge the stent.

While the stent is in place, patients may carry on with most normal activities, however the stent may cause some discomfort during strenuous physical activity. Work and other daily activities may continue as normal. Sexual activity is also possible with a stent, but stents with a thread may significantly hinder sex. The stent also can rest on the prostate gland in men and with ejaculation/orgasm the prostate may have movement that is discomforting to the patient and similar to severe cramping or irritation. One should approach sex differently with a stent exercising caution and certainly using some type of protection to prevent transmission of some sexually transmitted diseases.
