Characteristics of the urethroplasty and our approach-Experience in patients with urethral stricture.

OBJECTIVE: Urethral stricture is a common pathology with different etiologic factors in different age groups and societies. In our research, patients who underwent urethroplasty because of urethral stricture were evaluated in terms of etiology, localization, surgical technique and demographic characteristics. MATERIAL AND METHODS: One hundred and sixty-three patients with a mean age of 53.43±16.5 years, operated between January 2008 and May 2016 because of urethral stricture were retrospectively included in the study. Diagnosis of the urethral stricture was established based on the complaints of the patient, results of urinalysis, urine culture, uroflowmetry, retrograde urethrography and/or voiding urethrography, and urethroscopy in case of need. Postoperative success for the patients was determined based on urinary flow rate and maximum flow rate of over 15 mL/sec were evaluated as success. RESULTS: Etiologic factors for urethral stricture included trauma in 40 (24.5%), urethral catheterization in 45 (27.6%), endoscopic procedure in 59 (36.2%), infection in 10 (6.2%), idiopathic etiologies in 9 (5.5%) out of 163 patients. Mean length of the stricture was 3.6±1.7 cm. While the indicated number of patients had buccal mucosa graft (n=73, 44.7%), penile skin flap (n=21, 12.8%), Heineke-Mikulicz repair (n=5, 3.0%), and end-to-end anastomosis (n=64, 39.1%). Mean follow-up period was 43.2±33.7 months. Buccal mucosa graft was applied as ventral (n=32, 43.8%), dorsal (n=22, 30.2%), and dorsolateral (n=14, 19.2%) onlay, and transventrally dorsal inlay (n=5, 6.8%) grafts. Average success rates were 83.5% (n=61/73) in buccal mucosa, 76.2% (n=16/21) in penile skin grafts; 85.9% (n=55/64) in end-to-end anastomosis and 80.0% (n=4/5) in Heineke-Mikulicz repair. CONCLUSION: Our assumption is that urethroplasty procedures have satisfactory long-term results, regardless of the location and size of the stenosis. According to our clinical experience, deciding on the most appropriate surgical technique by assessing each patient individually in experienced centers will increase success rates.
