Abstract
Introduction
Purpose of this study was to evaluate the efficacy of saline Sonourethrography (SUG) in
detection and evaluation of male anterior urethral strictures compared with retrograde
urethrography (RUG). Anterior male urethral stricture disease is a major health problem
representing a significant part of the workload of the radiologist and urologist. Its management
remains a challenge to both the urologist and the patients. The appropriate choice of management
of anterior urethral stricture depends largely on a reasonable, safe and high diagnostic yield of
preoperative imaging methods.
Methods
Hospital based prospective cross-sectional study was used at Tikur Anbessa specialized hospital
from October 2020 – September 2021. The study participants were all patients on work up for
clinically suspected anterior urethral stricture that came to urology department & radiology
department at TASH. There were a total of 44 patients involved in this study. Data was collected
directly by interviewing the patients and as well as by reviewing Salinesonourethrography and
retrograde urethrography imaging’s done for the patients using a structured questionnaire. The
data was analyzed using SPSS software and results were presented using text, tables and graphs.
The results of both methods (Salinesonourethrography and Retrograde urethrography) were
compared. Retrograde Urethrography was considered as the gold standard for this comparison.
Result
In 68.18% of the patients (30 patients) anterior urethral stricture was identified by retrograde
urethrography. Most of the patients with anterior urethral stricture were in the age group of 41-60
years (41.9%). The two most common presenting symptoms were weak stream and dysuria each
comprising 38.7% and 32.3% respectively. The most common site of stricture was bulbar urethra
and the most frequent length of stricture was short segment stricture. Moderate degree of
Spongiofibrosis was the mostly identified degree of Spongiofibrosis. The sensitivity and
specificity of SSU were 86.66% and 92.85% respectively and the PPV and NPV were 96.29%
and 76.47% respectively.
