[Sonography of the lower urogenital system].

A suprapubic transvesical sonography of the lower urogenital tract performed by a radiologist is part of a complete investigation of the abdomen. The application of endosonographical methods is mainly subject-related in gynecology and obstetrics as well as in urology. The ranking rate of suprapubic transvesical sonography is compared with endosonographical methods, and, as indicated, also with CT und MRI. Concerning pathological-sonographical details, it is referred to the relevant literature. The diagnostic accuracy depends on the experience and ability of the investigator.

[Ultrasound image of the gallbladder fossa after cholecystectomy in the immediate postoperative period].

70 patients clinically classified as n.a.d. were sonographically examined for evaluation of the gallbladder fossa within two weeks after cholecystectomy. Four marked signs were noted. In 35 patients (50%) we found homogeneous echogenic formations of triangular, band-like, or oval shape in the bed of the gallbladder. In 25 cases (35.7%) inhomogeneous structures were seen. In 6 cases (8.5%) cystic structures resembling the normal gallbladder were seen which were interpreted as representing seromas or liquified haematomas. In 4 patients (5.7%) the bed of the gallbladder was entirely normal. Whether the gallbladder bed was closed by sutures or not, had no statistically significant effect on ultrasound appearance.

[MRT of bladder carcinoma: tumor staging and gadolinium contrast behavior].

33 patients with tumours of the urinary bladder were studied via MR, both with and without the paramagnetic contrast medium Gd-DTPA. Results were compared with the final pathological classification after TUER and bimanual palpation. The signal intensity ratio of tumour tissue/fat and tumour/muscle were calculated on T1 weighted images and after GD-DTPA and examined for their statistical significance. The increase in signal intensity of the tumours was statistically significant (Wilcoxon test p less than 0.01). There was no advantage for the T2 weighted images compared with Gd-contrasted enhanced T1 weighted images. MRI staging was correct in 28 out of 33 cases (accuracy 84.8%). Because of the relatively short acquisition time of T1 weighted images and the specific tumour enhancement, administration of Gd-DTPA proved to be of help in the staging of the carcinoma of the bladder. Two small tumours and regressive changes in central areas of tumours were recognised after Gd-DTPA.

[Can ultrasound detect skeletal metastases?].

78 radiologically certified skeletal metastases--osteolytic as well as osteoplastic--were examined via sonography. A defect of the cortex could be seen in 82%, a periostal reaction in 28.2% and a concomitant soft tissue tumorous formation in 79.4%. In proving a soft part component sonography is superior to the conventional x-ray. Our study shows that osseous metastases can be verified by sonography.

[Size relations of the spleen and lymph nodes in normal and pathologic processes].

63 spleens and 79 lymph node specimens, both normal and diseased, were measured in three planes. The ratio of length to width and to thickness was established to determine if characteristic changes in proportion - in connection with the expansion of the respective organs - are evident. The healthy spleens did not differ markedly from the diseased ones, whereas striking differences were obvious among the diseased lymph nodes. Lymph nodes involved in malignant disease appeared globular, whereas those involved in inflammatory disease showed a longish and flattened shape.

Sonographic staging after nephrectomy for tumours.

Sonography for postoperative staging after malignant renal tumours was evaluated in this study based on multiple examinations in 63 patients. Sonography permits a critical examination of the liver, the abdomen in general, the retroperitoneal space, including the renal fossa and solitary kidney. Local recurrences after hypernephroma operation were found in 5.3% and after nephrectomy for renal pelvic carcinoma in 68%. Retroperitoneal lymph node metastases appeared in 17% of the patients operated on renal pelvic carcinoma and in 7.6% after hypernephroma operation. These data indicate that special attention should be drawn to the renal fossa after tumour nephrectomy. The higher incidence of recurrences in the renal fossa, and metastatic lymph node involvement in patients following nephrectomy for renal pelvic carcinoma compared with the situation after hypernephroma operation might be explained by the difference of the lymph drainage between the renal pelvis and renal parenchyma which, in addition, includes a separate ontogenetic development. The majority of secondary lesions in hypernephroma patients occur as lung and bone metastases which have been discovered by conventional X-ray examination. These data are not statistically evaluated in the study.

Sonography in blunt renal trauma.

In 27 patients with blunt renal trauma, sonography was used as diagnostic method. In principle, sonography was performed after the urogram. In 15 cases pathological findings were present: 5 subcapsular and perirenal hematomas; 3 ruptured kidneys and 1 renal pedicle injury; in 6 cases pre-existing lesions of the kidneys were present (1 cyst, 3 hydronephrotic kidneys and 2 tumors). A positive urogram and a pathological sonogram lead to the angiography in particular when the possibility of injury of other organs is suspected, or when urographically a nonfunctioning kidney simulates a lesion of the renal pedicle. The adoption of this diagnostic sequence is most economical, it provides the clearest findings and is the least irksome for the patients.

[Differential sonographic diagnosis in kidney failure. Uremia caused by tumor infiltration of both kidneys in malignant lymphoma].

Ultrasonography is in general an ideal addition to radiodiagnostic methods in diseases of the kidneys. In renal failure ultrasonography is an excellent independent diagnostic method, which can give good informations about the form, size and internal structure of the kidneys. The different causes of renal failure can be clarified. The typical sonographic patterns as in endstage kidneys, hydronephrosis, cystic dysplasia, acute and subacute glomerulonephritis are well known. A rare cause for renal failure is massive cellular infiltration of both kidneys in malignant systemic diseases of the lymphoreticular system. The sonographic picture of this condition is largely unknown and therefore two cases are demonstrated, which show considerable enlarged kidneys with a diminished irregular internal echo pattern.

[Diagnosis of subphrenic abscess by sonography (author's transl)].

The diagnosis of a subphrenic abscess by sonography is based mainly on the experience of the examiner. A short description of the normal subphrenium is given. The diagnostic criteria for a subphrenic abscess and the differentialdiagnosis are discussed. In 19 cases of subphrenic abscess in question the diagnosis was missed in two cases, giving a success rate of 89.5%.

[Sonographic findings in blunt renal trauma (author's transl)].

The kidneys are beautiful organs for ultrasonography, because of their position, well defined characteristic appearance and excellent acoustic qualities. This is highly important for assessing all pathologies leading to macromorphological changes of the kidneys including these in blunt renal trauma. We could'nt find any paper on this topic in the recent literature available for us. Our own material in renal blunt trauma includes 17 patients. There were no pathological findings in 7, and pathological findings in 10 of them. Sonographic accuracy in severe trauma of the kidney is about 100%, excluding hydronephrotic kidneys, which cannot always be distinguished from a bigger parapelvic cyst. Urogramm resp. Uronephrotomogramm should be performed and studied thoroughly. Exceptions are Iodine allergy and pregnancy.

[Acute renal vein thrombosis in infancy (author's transl)].

Two cases of acute renal vein thrombosis are presented. Instead of angiography, sonography was used to perform the diagnosis. After short discription of the etiology, clinic and roentgensymptomatology, the sonographic semiology is emphasized. In the discussion the sonographic differentialdiagnosis is reviewed and the possible therapeutic proceedings are mentioned. The value of sonography as non-invasive method, especially in newborn is therefore established.

Ultrasonic diagnosis of the retroperitoneal space.

A precondition for ultrasonic diagnosis of the retroperitoneum is an optimal preparation of the patient to eliminate flatulence in the intestines. If the large vessels of the retroperitoneum are well demarcated, the optimal examination conditions are present. Tumorous and cystic changes of 2 cm or more, can be visualized. Difficulties, however, in the coordination and the differentiation of retroperitoneal tumors from organic tumors (pancreatic tail, splenic and gynecological tumors) can arise. Tumor changes in the lymphatic nodes, the adrenal gland and the sympathetic trunk, tumors in the retroperitoneum from other causes, and aortic aneurysms are discussed.

[Sialographic findings in inflammations of the salivary glands (author's transl)].

The greatest part of all diseases of salivary glands are caused by inflammations. The differential diagnosis to other diseases, e.g. tumors, if of great importance. The sialography has hereby developed to an important diagnostic measurement. There is a discussion about the technique of the sialography and its simple performance as well as the high effectiveness of this X-ray examination. The X-ray morphology of different kinds of inflammations is various. The acute inflammations are characterized by narrowing of ducts, the subacute inflammations by the pathological staining of the parenchyma, and the chronic by the increased changes of the Stenon's or Wharton's duct, respectively of ducts with superior range.
