Recently, Mr. NQK (29 years old) had a dull pain and swelling in his left testicle, which gradually increased over 2 weeks, accompanied by a constant low-grade fever. The young man went to the hospital for examination and treatment but did not get better, so he went to the emergency room at Nguyen Trai Hospital (HCMC).
At the Emergency Department, after examination and consultation, the doctors diagnosed the patient with left testicular and epididymitis, so he was transferred to the Department of Urology for treatment.
After 7 days of intravenous antibiotic treatment combined with strong anti-inflammatory and pain relievers, the patient's left testicle was less swollen, pain was gone, fever was gone, and the infection was within normal limits. However, the patient still complained of difficulty urinating, straining to urinate, and a feeling of not being able to urinate completely.
Taking the patient's medical history, the treatment team noted that 3 years ago, the young man had been stabbed in the chest and had to undergo surgery, but during the surgery, a urethral catheter could not be placed, and the bladder had to be opened to the skin.

The patient was found to have a long urethral stricture (Photo: Doctor).
Performing a urethroscopic examination and cystography, the doctors noted that the patient had a narrow penile urethra, 2cm from the opening of the urethra, with a narrow segment 4-5cm long. The patient was prescribed urethral reconstruction surgery, by grafting oral mucosa (the soft skin layer inside the mouth).
According to Dr. Phan Lien Khuong, Head of the Department of Urology, during the surgery, the treatment team made an incision to remove a thin piece of mucosa from the mouth area, 1.5x6cm long, processed and sutured the graft to the remaining mucosa of the urethra.
Next, the patient was stopped from bleeding, the corpus spongiosum and foreskin were sutured closed, and the grafted area was bandaged. After surgery, the patient was given a combination of antibiotics for several days. Three weeks after surgery, the young man had his urethral catheter removed. Currently, the patient urinates normally, feels comfortable, and has no infection, etc.
Speaking to Dan Tri reporter, Master, Doctor Vo Duy Tam, a member of the surgical team, shared that urethral stricture is a complicated disease. The choice of treatment depends largely on the location and length of the narrowed segment.
In cases of long penile urethral stricture, where end-to-end resection is not possible, the method of reconstruction using autologous grafts has many advantages. In particular, reconstruction of the urethra using oral mucosal grafts gives good results, with a high success rate according to medical literature (82-89%).

Currently, the Department of Urology of Nguyen Trai Hospital has gradually developed and implemented the above technique.
Doctors advise people that urethral stricture can be caused by many different reasons, from congenital, autoimmune to acquired (such as after trauma, after urethritis, due to medical intervention...) but all lead to difficult urination and other urinary disorders.
Therefore, if you feel that you have urinary obstruction (including difficulty urinating, having to strain to urinate, taking a long time to urinate, weak or small urine stream, not being able to urinate completely...) you should go to the doctor to be checked and screened for urethral stricture.
Especially in cases with risk factors such as: History of urethritis, genital trauma, previous medical intervention (urinary tract endoscopy, urethral catheter placement...) examination is necessary.
"Do not be subjective with symptoms of difficulty urinating, because they can lead to complete loss of bladder function as well as affect the activity of the urinary tract, potentially leading to kidney failure," the doctor warned.
