[Results of Johanson's urethroplasty (author's transl)].
In the period 1951-1974 urethroplasty according to Johanson was carried out in 467 patients. In 391 patients the repair was complete. The authors set forth the pathogenesis and localization of the stenoses and traumas that require plastic correction and point out the various improvements in operative technique that have been developed in recent years. In only 16 of the 391 patients was the Johanson method attended by adverse results; 8 patients had to undergo a further urethral bougienage. Out of 931 interventions in 467 patients, 4 died--none since 1967. Complications were valvular necrosis, suture dehissence hematoma, and abscess formation; such complications were seen in 6% of patients in the early operations. After modification of the surgical procedure this figure was reduced to 3%. Recurrence of stricture occurred in 63 cases. These were controlled after repeating the operation.
