Endoscopic treatment for bulbar-membranous urethral obliteration: evaluation of the efficacy and safety

Introduction. The problem of endoscopic treatment for urethral strictures and obliterations remains unresolved. It is necessary to note that the effectiveness depends not only on the right indications, but also on the surgical technique and the study of the postoperative period management.Objective. To evaluate the efficacy and safety of endoscopic treatment of patients with bulbar-membranous urethral obliteration.Materials and methods. The study included 103 patients aged 20 to 89 years with bulbar-membrane urethral obliteration, who, for some reason or another, cannot perform urethroplasty. The patients underwent endoscopic recanalization of the urethra under X-ray control with further circular transurethral electroresection (TUR) of the scar tissues in the urethral obliteration zone (after 6 – 7 days).Results. The average age of the patients was 61.1 ± 18.3 years. After the operation, self-urination was restored in all patients. The average maximum urine flow rate (Q max) before discharge from the hospital was 12.6 ± 0.5 ml/s. Throughout the follow-up period, Q max tended to increase and at the end of the study (36 months) reached values of 16.5 ± 0.5 ml/s. During the first year of follow-up, 18 (17.5%) patients developed recurrent urethral stricture. Seventeen (16.5%) patients underwent repeated circular TUR of scar tissue in the zone of recurrent stricture. The effectiveness of the treatment was 90.0%.Conclusion. Endoscopic urethral recanalization followed by TUR of scar tissue in the obliteration zone is an effective and safe method in the treatment of bulbar-membranous urethral obliteration with length less than 1.0 cm.
