anterior urethrotomy

Urethral stenosis is extensive, can not be treated with urethral dilatation, or can be treated with urethroplasty and urethroplasty because of the long stenosis or multiple urethral resection of the urethra, which can cause urethral anastomosis. . There are many surgical methods, and urethrotomy and urethroplasty can be completed in one stage or in stages. Staged, first urethrotomy, open the urethral stenosis or occlusion, or artificial hypospadias, 3 to 6 months, then urethroplasty. Treatment of diseases: urethral stricture Indication Anterior urethrotomy is suitable for multiple stenosis or long stenosis of the corpus cavernosum, which cannot be treated by urethral dilatation or urethral anastomosis. Surgical procedure 1. Cut the urethral stricture A metal urethral probe is inserted from the outer urethra, and its tip is blocked at the distal end of the stenosis. The tip of the probe is tilted toward the ventral side of the penis, where the penile skin, subcutaneous tissue, and corpus cavernosum are cut until the tip of the probe is exposed. 2. Formation of artificial urethra fistula After the urethra is incision, the penis or scrotal skin, subcutaneous tissue and stenotic urethra are cut longitudinally along the incision. The length of the incision should reach 1 cm of the normal urethra at both ends. The urethra is examined with a F2024 metal urethra probe. After confirming that there is no stenosis, the wound edge of the skin and the urethra is sutured intermittently with a silk thread to form an artificial urethra.
