Direct Visual Internal Urethrotomy (DVIU) in the Management of Male Urethral Strictures. A Single Center Experience about 44 Patients

Abstract

Introduction: Male urethral stricture is one of the oldest urological disorders. Many techniques have been proposed to treat them, including endoscopic internal urethrotomy (DVIU). Material and Methods: To evaluate the contribution of this technique in the treatment of urethra narrowing, a retrospective study on the records of patients with urethral stricture treated with endoscopic internal urethrotomy between January 2014 and December 2021 in the urology division of the Souro Sanou University Teaching Hospital. Results: A total of 44 male patients with urethral stricture were treated with this technique and 48 procedures were performed. The average age of the patients was 53.2 ± 18.2 years. The etiology of the stricture was dominated by iatrogenic, infectious, traumatic and idiopathic causes in 43.2% (n = 19), 27.3% (n = 12), 20.4 % (n = 9), and 9.1% (n = 4) respectively. The location of the stricture was bulbar in 72.7%, and the anterior penile urethra in 15.9%. The overall success rate was 72.7% with satisfactory urination without dysuria, evaluated after removal of the urinary catheter, at three months this rate fell to 69.1%, and at 6 months this rate was 67.5%. Five cases (5) of extravasation of blood or irrigation fluid into the scrotum were reported and managed conservatively as well as two (2) cases of false routes with postoperative oedema of the penis were observed. Conclusion: DVIU is a simple technique, free of major morbidity and requiring only short-term hospitalization. It can be proposed as a first-line treatment for urethral stricture.
