Assessment Of Diagnostic Performance Of Saline Sonourethrography In The Evaluation Of Male Anterior Urethral Stricture In Black Lion Specialized Hospital Addis Ababa University Addis Ababa Ethiopia
IntroductionrnPurpose of this study was to evaluate the efficacy of saline Sonourethrography (SUG) inrndetection and evaluation of male anterior urethral strictures compared with retrogradernurethrography (RUG). Anterior male urethral stricture disease is a major health problemrnrepresenting a significant part of the workload of the radiologist and urologist. Its managementrnremains a challenge to both the urologist and the patients. The appropriate choice of managementrnof anterior urethral stricture depends largely on a reasonable, safe and high diagnostic yield ofrnpreoperative imaging methods. rnrnMethodsrnHospital based prospective cross-sectional study was used at Tikur Anbessa specialized hospitalrnfrom October 2020 – September 2021. The study participants were all patients on work up forrnclinically suspected anterior urethral stricture that came to urology department & radiologyrndepartment at TASH. There were a total of 44 patients involved in this study. Data was collectedrndirectly by interviewing the patients and as well as by reviewing Salinesonourethrography andrnretrograde urethrography imaging’s done for the patients using a structured questionnaire. Therndata was analyzed using SPSS software and results were presented using text, tables and graphs.rnThe results of both methods (Salinesonourethrography and Retrograde urethrography) wererncompared. Retrograde Urethrography was considered as the gold standard for this comparison. rnrnResultrnIn 68.18% of the patients (30 patients) anterior urethral stricture was identified by retrogradernurethrography. Most of the patients with anterior urethral stricture were in the age group of 41-60rnyears (41.9%). The two most common presenting symptoms were weak stream and dysuria eachrncomprising 38.7% and 32.3% respectively. The most common site of stricture was bulbar urethrarnand the most frequent length of stricture was short segment stricture. Moderate degree ofrnSpongiofibrosis was the mostly identified degree of Spongiofibrosis. The sensitivity andrnspecificity of SSU were 86.66% and 92.85% respectively and the PPV and NPV were 96.29%rnand 76.47% respectively.
