Overview
Visual Internal Urethrotomy is an endoscopic treatment for selected urethral strictures. A specialized instrument is introduced through the urethra and the scar tissue causing narrowing is carefully incised to widen the urinary passage.
Common Symptoms
Weak urine stream, difficulty urinating, straining, spraying of urine, prolonged urination, recurrent urinary infections and urinary retention.
Possible Causes
Previous catheterization, urinary instrumentation, trauma, infection, previous urethral surgery and inflammatory conditions.
Diagnosis
Evaluation may include urine tests, uroflowmetry, post-void residual measurement, urethrography and urethroscopy.
Treatment & Procedures
A urethroscope is introduced through the urethra. The narrowed segment is identified and the scar tissue is carefully incised to improve the urinary passage.
Recovery & Follow-up
A urinary catheter may be kept temporarily. Follow-up is required to assess urinary flow and monitor for recurrence.
Benefits
Minimally invasive procedure, no external incision, relatively short procedure and potential improvement in urinary flow in appropriately selected patients.
