Risk of recurrent stricture following internal urethrotomy. Prospective ultrasound study of distal male urethra.

A group of 60 patients was examined prior to surgery in a prospective ultrasound study of the distal male urethra to predict the individual rate of stricture recurrence after internal urethrotomy. The patients were divided into 2 groups according to the ultrasound findings. One group had no evidence of scarred tissue and no recurrence was predicted. The other group did have periurethral scarring and stricture recurrence within approximately 6 months was predicted. We present the ultrasound findings and discuss the accuracy of the predictions. Correct prognoses were made in 92.9% of cases.
