OBJECTIVE: This study was carried out to compare the diagnostic accuracy of transvaginal sonography (TVS) and transvaginal saline contract sono hysterography (TVSCSHG/SCSH/SHG) using histopathology diagnosis as the gold standard.\nPATIENTS & MATERIALS: This was a prospective study at the radiology department of Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital. Two hundred and fifty consecutive patients were counseled and evaluated by TVS and TVSCSH after informed consent. However, only seventy five patients who had surgery or endometrial biopsy and histological diagnosis within two months after TVS & SCSH were included in the study. Predictive values, sensitivity and specificity were calculated by correlating their results with final diagnosis.\nTVSCSH had 100% diagnostic accuracy for submucous polyps, submucous fibroid, adhesion/synechiae and endometrial cancer with sensitivity, specificity, NPV and PPV of 100%. TVS, on the other hand had diagnostic accuracy of 89.3%, 88.0%, 93.3% and 98.7% for polyps, submucous fibroid, adhesion/synechiae and endometrial cancer respectively.\nThough the diagnostic accuracy of SCSH was 98.7% for endometrial hyperplasia, it was still slightly better than 92% for TVS. The TVSCSH sensitivity, NPV and PPV for endometrial hyperplasia were all better than that of TVS.\n45.3% (34) of the patients were normal while 41 (54.7%) patients had abnormalities. Submucous fibroid was the commonest abnormalty (41.5%) followed by synechiae (19.5%) while endometrial cancer was the least (4.9%)\nConclusion: Transvaginal saline contrast sonohysterography should be used routinely for evaluation of patents with abnormal uterus bleeding.\nOur results showed that sonohysterography is the more accurate of the two modalties with a superior diagnostic accuracy of 100% agreement with the gold standard (histology) for all but one of the uterine cavity lesions.
Evaluation of urethra strictures may be performed by different imaging modalities. However retrograde urethrography (RUG) has remained the gold standard. Recently, saline contrast urethrography is considered as an alternative to RUG in the assessment of urethra pathology. This technique offers the advantage of cost effectiveness and nonexposure to radiation.\nAIMS AND OBJECTIVES: The aim of this study was to sonographically (SUG) and radiologically (RUG) evaluates anterior urethra in males with clinical suspicion of urethral strictures and compares radiological and surgical findings.\nPATIENTS AND METHODS: One hundred patients with symptoms and signs of urethral stricture were selected from urologic clinic of Ladoke Akintola University Teaching Hospitals in Oshogbo and Ogbomosho. These patients had RUG, SUG and surgery. The findings on the urethra were compared and analyzed using statistical package for social sciences (SPSS) 18.0 for windows. \nRESULTS: The age range of the patients was 18 years to 80 years with a mean and modal age of 55.42±15.04 years and 61-70years respectively. The commonest symptom was urinary dribbling 71(94.7%) while Infection, reported in 46.7% was the highest attributable factor. Both SUG and RUG correlated well with surgical findings but SUG had a better sensitivity, 98.6% compared to of 95.0% for RUG. The bulbar strictures 67(89.3%) were significantly (p-value of 0.001) more than penile strictures 3(4.0%). Majority of the bulbar strictures were found in the 6th and 7th decades with 24% and 25.3% of the patients respectively, while majority of the penile strictures occurred in the 4th decade (2.7%). Both procedures correlated well with surgery with Pearson correlation values of 0.996 and 0.938 for SUG and RUG respectively. Periurethral spongiofibrosis (37patients) and calcifications (19 patients) were seen only on SUG while RUG detected urethral diverticulum(3 patients), which were not visualized on SUG. Both SUG and RUG correlated well with surgical findings but SUG had a better sensitivity, 98.6% compared to of 95.0% for RUG.\nCONCLUSION: Both RUG and SUG are useful in stricture detection and location. However, SUG had higher sensitivity and correlation with surgical findings in this study compared to RUG.\nCONCLUSION: Both RUG and SUG are useful in stricture detection and location. However, SUG had higher sensitivity and correlation with surgical findings in this study compared to RUG.
