Application value of ultrasonography in penile diseases / 中华男科学杂志

Penile disease is one of the male urological diseases. Although the penis is a small organ, once the problem occurs, it often brings great trouble to the patient. Therefore, the accurate diagnosis of penile disease is particularly important. High-frequency ultrasonography, with its advantages of noninvasiveness, safety, low cost, easy operation and reproducibility, can clearly show the structure and blood flow of the penis and has a significant value in the diagnosis and follow-up of penile diseases such as vascular erectile dysfunction, priapism, penile injury, penile neoplastic and non neoplastic nodules. Meanwhile, the development of new technologies such as shear wave elastography (SWE) and contrast enhanced ultrasound (CEUS) has made up for the shortcomings of traditional ultrasound imaging, expanded the application of ultrasound in penile diseases, and improved the efficiency of ultrasound diagnosis of the diseases. This article focuses on the application value of ultrasound in erectile dysfunction, priapism, penile cavernous injury and penile tubercle, as well as the latest progress in such new technologies as SWE and CEUS applied to penile diseases.

Contrast of Ultrasonography in Diagnosis for Hepatorrhexis with Operative Exploration (Report of 120 Cases) / 中国普外基础与临床杂志

Objective To discuss the diagnosis value of ultrasonography in hepatorrhexis. Methods The contrast of ultrasonography for 120 cases of hepatorrhexis with operative exploration was made. Results All of the 120 patients were examined with ultrasonography, fragmentation of liver parenchyma in 55 cases, dehiscence of liver parenchyma in 38 cases, liver subcapsular hematoma in 12 cases, and spontaneous rupture of liver cancer in 7 cases. All of the 120 patients were confirmed hepatorrhexis with laparotomy. The positive diagnostic rate of ultrasonography in the hepatorrhexis was 93.3%.Conclusion Ultrasonography is valuable for diagnosing hepatorrhexis and it is one of the important diagnostic approaches.

B-mode Ultrasonic Diagnosis of Complications in Hepatic Hydatidosis / 中华超声影像学杂志

Hydatidosis is the largest parasific disase in human being. The patients often contract hydatidosis in the childhood. The slow growth of hydatid cysts in the organ involved may lead to a protracted course of disease. In the early stage of the diseases, there are no distinct subjecive symptoms. Early diagnosis is difficult by routine examination. The complications of hydatidosis causing serious damage to the organs may often lead to sudden death. It is essential to make an early and correct diagnosis and give treatment. B-mode ultrasonography not only detects the location, dimension and chracteristics of hydatid cysts but also shows the pathological changes of the various complications caused by hydatidosis and faciliates to select the best program of operation. B-mode ulttasonography is the method of choice in the diagnosis of hydatidosis. In this series of 931 patients with hepatic hydatid disease, the diagnostic accuracy rate of B-mode ultrasonography reached 98. 8%.

Diagnosis of intraorbital angioma by color Doppler ultrasonography / 眼科

Nineteen eyes of 18 patients with intraorbital angioma were studied by color Doppler ultrasonography and the results were compared to the diagnosis of CT (16 eyes), MRI (5 eyes) and pathology (5 eyes). Blood flow images in intraorbital angioma were detected in 15/19 eyes (78.95%), and blood flow spectrums were analyzed in 7/19 eyes (36.64%). It is suggested that color Doppler ultrasonography be helpful to the identification of the intraorbital angioma.
