[Perineal urethrostomy: results, clinical, statistical and terminological aspects]

The analysis of the results of perineal urethrostomy for urethral stricture in men for the period from 2000 to 2020 is presented in the article. We identified 29 original articles devoted to this technique, including 4 Russian and 25 foreign publications. In two studies, there were more than 100 patients, four studies included from 51 to 77 men, and in remaining studies less than 50 patients were analyzed. Complete data on all pre- and postoperative aspects of perineal urethrostomy were provided only in a few studies. In the overwhelm of cases, perineal urethrostomy was performed after one or several unsuccessful reconstructive procedures and only in few patients it was done prior to various types of urethroplasty. It was not possible to establish any association between etiological factors and localization of urethral stricture among these patients. The incidence of pan-urethral stricture ranged from 28.6% to 100%. Only in one study the average stricture length was 2 cm, while in all other studies it was 5 cm or more. Postoperative follow-up was on average 14 to 62 months. Treatment success with perineal urethrostomy ranged from 0% to 100%, but in most studies it was 75% or more. The most common perineal urethrostomy technique used included Blandy technique, and Johanson and 7-flap techniques.
