Direct Visual Internal Urethrotomy (DVIU)
Direct visual internal urethrotomy (DVIU) is a surgery to repair a narrowed section of the urethra in male patients.
This procedure is generally used to treat urethral stricture, a narrowing of the urethra at any point from the bladder to the tip of the penis, which can cause difficulty with urination and changes in ejaculation.
During the procedure, a contrast liquid is injected into your urethra. An X-Ray is taken to reveal the location of the stricture. Then, your doctor inserts a small scope into the urethra to repair a narrow segment of the stricture. Your surgeon may inject a medication into the stricture to reduce recurrence. A catheter is placed to divert urine around the healing area.
After the Procedure
Generally, you will have a urinary catheter for two to three days. You may see a small amount of blood in your urine. You should experience immediate improvement of the urine stream after catheter removal. Your doctor will monitor your urine stream for several months.
