Course for chronic urethritis
After treating the external opening, 5–10 ml of solution is injected into the urethra, the canal is clamped for 5–15 minutes so that the drug comes into contact with the mucous membrane of the entire anterior urethra, then the patient urinates. Instillations are prescribed after the infection has been eliminated by culture, when burning, discharge, and itching persist; drugs are selected according to stage (antiseptics for residual inflammation, regenerating agents for dryness and scarring of the mucous membrane). A course of 5–10 procedures every other day is combined with medications and physiotherapy.
Why are instillations performed?
Instillation is the introduction of a drug directly into the bladder or urethra through a catheter, which creates a high local concentration without systemic action. It is used for chronic and interstitial cystitis, radiation cystitis, chronic urethritis (antiseptics, hyaluronic acid, heparin, drugs for mucosal restoration), as well as in oncourology - intravesical BCG and chemotherapy after TUR of a bladder tumor to prevent relapses.
How it goes
After treating the external opening of the urethra and introducing an anesthetic gel into the bladder, a thin catheter is inserted, residual urine is removed, 20–50 ml of solution is injected, and the catheter is removed. The drug is held for 30 minutes - 2 hours (with BCG - 2 hours, changing position). Course - from 6 to 10 procedures with an interval of 2 days to a week; oncology regimens - 6 weekly induction, then maintenance.
