[Retrograde balloon catheter dilatation of urethral stenosis--experience in benign prostatic hypertrophy and postoperative urethral stricture].
Retrograde transurethral balloon dilatation of urethral stenosis was performed in five patients: four patients with benign prostatic hypertrophy and one with urethral stricture following open prostatectomy. Significant resolution of symptoms of dysuria was seen in four patients throughout the follow-up period of 12 to 18 months. A balloon diameter of 25 mm was considered to be necessary for prostatic hypertrophy. The unsatisfactory result in one patient with prostatic hypertrophy was believed to be caused by incomplete dilation due to a small balloon diameter. Mild transient hematuria was seen in all cases. Only one patient with postoperative urethral stricture complained of pain during balloon inflation, while other patients with prostatic hypertrophy did not complain of any apparent pain. We conclude that this technique is a safe and effective method of treatment for prostatic hypertrophy and other urethral strictures.
