Some of the side effects that can result from the insertion of a urethral stent include irritation of the urinary bladder and a crystal coating on its surface. The irritation causes frequent urges to urinate, according to Urology West. Other side effects of the procedure include an increased risk of bacterial infection at the incision area, pressure in the urinary bladder as a result of presence of the ureteral stent and kidney bleeding, as stated by RadiologyInfo.org.
The side effects result from some of the related surgical procedures, including partial nephrectomy, urectomy, pyeloplasty, ureterolysis and transureteroureterostomy, as described by Mayo Clinic. These procedures involve the insertion of a urethral stent, a catheter or percutaneous nephrostomy which results in the side effects. The operation involving these procedures causes damage to the surrounding organs and allergic reactions due to the different medications and surgical instruments that they require.
The ureteral stent can also develop urinary tract infections when used with an underlying kidney infection and back pain when passing urine, especially on the side of the body where the stent is fixed, according to Urology West.
The stent may also become displaced, slipping into the bladder or even falling off. Urination may be difficult as the new valve becomes too strong, as the NHS details.
