Role of Grayscale and Color Doppler Ultrasonography in the Diagnosis and Outcome Analysis of Testicular Torsion

Introduction. Liver diseases with disturbances of hepatic and splanchnic circulation lead to the portal hypertension, with or without a portal vein thrombosis. Objective. This study was based on the testing of hypothesis that more data and more precise diagnosis in patients with disorders of portal circulation can be obtained by using color Doppler ultrasonography (CDU) and computed tomography (CT) with contrast. Methods. The study was conducted from February 2011 to May 2014 and it comprised 120 patients who were suspected to have portal hypertension or already had clinical confirmation of the portal hypertension, patients with hepatitis, and some patients with hematological diseases. The first group of 40 patients was examined by conventional ultrasonography and CDU, the second group by contrast CT, and the third group of patients was examined by both methods (CDU and contrast CT). After six months of adequate therapy, the patients had control examinations with the same diagnostic technique used during their first examination. Results. Retrospective analysis showed that CDU is more sensitive than CT in the assessment of presence and age of thrombi (CDU 93.9%; CT 86.1%). CT gives precise data in detection of portosystemic collaterals. Sensitivity of CT is 100% and its specificity is 67%. Cumulative sensitivity and specificity for most parameters were increased in patients with portal hypertension when both methods were applied. Conclusion. This study emphasizes the possibility of early and more accurate diagnosis achieved when combining two radiological techniques (CDU and contrast CT scan), which is not the case when these methods are used separately.

Doppler Study

INTRODUCTION: Ultrasonography is extremely well suited to study of scrotum and its contents. Ultrasound is simple to perform, quick, non-invasive, low cost effective, easily reproducible, widely available and does not involve irradiation of gonads.It is very helpful in differentiating intratesticular and extratesticular pathologies. Ultrasound is the modality to differentiate solid from cystic lesions of testes and with the introduction of color Doppler, it becomes easiear to assess the viability of testis in cases of torsion and guiding the treatment accordingly. USG is helpful in differentiating torsion/ischaemia of testis from the acute inammatory pathologies. Role of other Modalities: CT and MRI have dominated imaging of other regions of the body, they have certain restrictions in evaluation of scrotal diseases. Computed Tomography delivers radiation to gonads, On the contrary, MRI imaging is expensive and not readily obtainable. Radionuclide scan helps in equivocal presentations to assess vascularity within the testis in setting of torsion but its readily availability and cost is the main set back. AIM: To assess the role of high frequency gray scale and color doppler ultrasonography in evaluation of epididymorchitis. MATERIAL & METHODS: SAMPLE: 50 cases of scrotal pathology were taken using High-frequency real time gray scale ultrasonography and Color Doppler . Patients were referred to our department for scrotal ultrasonography and Doppler study by department of Urology and department of Surgery of SRMS IMS Bareilly. RESULTS: In the present study total evaluated cases of epididymoorchitis were 15,among them 11 cases were acute and 4 cases were of chronic epididymoorchitis.. Majority of cases were having unilateral involvement with 1 case of B/L involvement. USG gray scale found heterogenous echogenicity or reduced echogenicity in acute EPO while the echogenicity was reduced with calcication in chronic EPO. .Doppler study found increased vascularity in majority of cases of acute EPO with reactive hydrocele while vascularity was either normal or increased in chronic EPO without any reactive hydrocele. CONCLUSION: High-frequency gray scale USG helps in clear evaluation of anatomical structural alterations associated with acute scrotal inammatory diseases, and color Doppler USG is highly sensitive in diagnosing acute scrotal pathology. In addition, Color Doppler USG accurately differentiates between testicular ischemia and torsion from acute inammatory diseases in acute painful scrotal conditions.
