Urethral Stricture Surgery in Korea

Urethral Stricture Surgery in Korea: Advanced Solutions for Restoring Urinary Flow

Urethral stricture is a challenging urological condition characterized by the narrowing of the urethra, the tube that carries urine from the bladder out of the body. This narrowing, caused by scar tissue, can significantly impede urine flow, leading to a range of uncomfortable and potentially serious symptoms. When conservative treatments fail, urethral stricture surgery becomes necessary to restore normal urinary function. South Korea's leading urology centers are at the forefront of providing advanced and highly successful surgical solutions for urethral strictures, attracting patients seeking expert care.


Understanding Urethral Stricture

A urethral stricture occurs when scar tissue forms inside the urethra, making the tube narrower. This scarring can result from various factors:

  • Trauma or Injury: The most common cause, often from a direct injury to the perineum (e.g., straddle injury), pelvic fractures, or even medical procedures like catheterization or prostate surgery.
  • Infection: Past urinary tract infections (UTIs) or sexually transmitted infections (STIs) like gonorrhea or chlamydia can cause inflammation and subsequent scarring.
  • Inflammatory Conditions: Certain chronic skin conditions, such as lichen sclerosus, can affect the genital area and lead to urethral scarring.
  • Previous Surgeries: Procedures involving the urethra or prostate can sometimes lead to stricture formation as a complication.
  • Congenital: Rarely, some individuals are born with urethral narrowing.
  • Cancer: Though less common, cancer of the urethra or prostate can cause strictures.

Symptoms of Urethral Stricture:

Symptoms often develop gradually and can include:

  • Weak or slow urine stream
  • Difficulty starting urination (hesitancy)
  • Straining to urinate
  • Dribbling after urination
  • Feeling of incomplete bladder emptying
  • Frequent urination or increased urgency
  • Pain during urination (dysuria)
  • Urinary tract infections (recurrent)
  • Blood in urine (hematuria) or semen
  • Inability to ur urinate (acute urinary retention) – a medical emergency.


Diagnosing Urethral Stricture in Korea

Korean urologists utilize a comprehensive diagnostic approach to pinpoint the exact location, length, and severity of the stricture, which is crucial for planning the most effective surgical treatment.

  • Medical History and Physical Exam: Detailed discussion of symptoms and a physical examination.
  • Urine Flow Test (Uroflowmetry): Measures the speed of urine flow. A slow or weak flow can indicate obstruction.
  • Post-Void Residual (PVR) Urine Test: Measures how much urine remains in the bladder after urination, indicating incomplete emptying.
  • Retrograde Urethrogram (RUG): An X-ray procedure where contrast dye is injected into the urethra to visualize the narrowing.
  • Antegrade Urethrogram: If the stricture is in the back part of the urethra, dye may be inserted into the bladder to visualize the stricture from above. Often performed with RUG.
  • Cystoscopy: A small, flexible scope with a camera is inserted into the urethra to directly visualize the stricture, assess its characteristics, and sometimes allow for initial therapeutic attempts (like dilation).


Surgical Treatment Options for Urethral Stricture in Korea

For symptomatic urethral strictures, surgical intervention is often the definitive treatment, especially for recurrent or severe cases. Korean urologists are highly skilled in a range of advanced surgical techniques.

  1. Urethral Dilation:
  • Procedure: Involves inserting progressively thicker rods or balloons into the urethra to stretch and widen the stricture.
  • Considerations: This is a minimally invasive initial approach, but it often provides only temporary relief. Strictures frequently recur after dilation, requiring repeat procedures. It may be used for short, non-dense strictures.
  • Drug-Coated Balloon Urethral Dilatation: A newer method where a balloon coated with an anti-proliferative drug (like paclitaxel) is used to dilate the stricture and simultaneously deliver medication to prevent scar tissue regrowth. This aims to improve long-term outcomes compared to plain balloon dilation.
  1. Direct Vision Internal Urethrotomy (DVIU) / Optical Internal Urethrotomy:
  • Procedure: A cystoscope with a small knife or laser is inserted into the urethra, and the stricture is cut open. A catheter is usually left in place for a few days to weeks to keep the urethra open during healing.
  • Considerations: Like dilation, DVIU is minimally invasive but has a high recurrence rate (often 50-70%) especially for longer or denser strictures. It is typically considered for short (less than 1-2 cm), non-complex strictures, or as a first-line treatment in some cases. Many Korean urologists utilize this approach, similar to global trends for initial management.
  1. Urethroplasty (Urethral Reconstruction Surgery):
  • Procedure: Considered the "gold standard" with the highest long-term success rates (85-90% or higher), urethroplasty involves open surgical repair or reconstruction of the urethra. It is a more complex procedure, but it aims for a permanent cure.
  • Types of Urethroplasty commonly performed in Korea:
  • Excision and Primary Anastomosis: For short strictures (typically in the bulbar urethra), the scarred segment of the urethra is completely removed, and the two healthy ends are reconnected. This offers excellent success rates.
  • Substitution Urethroplasty (Graft or Flap Urethroplasty): For longer strictures or those where excision and anastomosis are not feasible, tissue is used to augment or replace the narrowed part of the urethra.
  • Buccal Mucosa Graft Urethroplasty: Tissue taken from inside the cheek is a common and highly successful graft material due to its robust blood supply and resistance to shrinkage. This technique is widely adopted in Korea, with clinics using it for reconstruction.
  • Skin Flaps: Tissue from the penis or scrotum can also be used, though less common than buccal grafts.
  • Considerations: Urethroplasty is more invasive, requires a longer recovery period (with a catheter typically in place for 2-4 weeks), but offers the best chance for a definitive cure and avoids repeated procedures. Korean surgeons are highly experienced in these complex reconstructive techniques.

Cost of Urethral Stricture Surgery in Korea

The cost of urethral stricture surgery in Korea is generally competitive and can be significantly more affordable than in countries like the United States, while maintaining high standards of care and advanced facilities.

  • Urethral Dilation/Internal Urethrotomy: These less invasive procedures are generally less expensive, ranging from USD 1,000 - USD 3,000+.
  • Urethroplasty (Open Reconstruction): This more complex surgery, depending on the type (excision/anastomosis vs. graft/flap), the length and complexity of the stricture, and the hospital/surgeon, can range from USD 5,000 to USD 15,000+. Bookimed indicates that urethroplasty costs in Korea can be around USD 11,000.

These figures are estimates and can vary. It's essential to get a detailed quote from your chosen clinic, which should include all aspects of care (anesthesia, facility fees, surgeon's fees, hospitalization, follow-up).


If you are experiencing symptoms of a urethral stricture, consulting with a qualified urologist in Korea is the crucial first step. They can accurately diagnose your condition and guide you toward the most effective surgical solution to restore your urinary health and quality of life.
