Double-blind comparison of iodamide and diatrizoate for excretory urography.

A double-blind comparison of meglumine iodamide and Renografin 60 (52% meglumine diatrizoate and 8% sodium diatrizoate) for bolus excretory urography was performed. Doses of 0.8 cc/kg. to a maximum of 55 cc were administered to fifty patients, twenty-five receiving each drug.There is a suggestion that iodamide may be superior to diatrizoate in pyelocalyceal opacification while being equal to diatrizoate in parenchymal opacification and in types and severity of side-effects.

[Quality control in urography using non-ionic contrast media (iopamidol) and induced hydration].

A trial was carried out with the aim to overcome the limits of the non ionic contrast medium (cm) in the urographic evaluation of ureters and bladder (poor distention and high density). 200 urographies have been performed in patients with normal renal function (group 1: sodium iodamide; group 2: iopamidol; group 3: iopamidol with glucose solution; group 4: iopamidol and injection of glucose solution after 15'). The scores ascribed to the four groups have been compared: in the comparison between ionic and non ionic cm a slight advantage of iodamide is evident, particularly in the evaluation of calyces and ureters. By adding glucose solution to iopamidol after 15', an improvement in the quality of the urogram has been obtained, but not statistically significant.

[Perirenal extravasation of contrast media during urography].

The authors report on 28 cases of contrast medium extravasates during urography. Own results and those obtained by other authors in respect of clinical findings, diagnosis and therapy are discussed. Our experiences have shown that an aggressive diagnostic or therapeutic approach is not indicated, since the sequels of these extravasates have no special clinical importance. As a rule, treatment is unnecessary, especially inpatient observation. Hence, our experiences confirm the trend to proceed as conservatively as possible.

Simplifying radiological examinations. Can it really be done in urography?

The value of commonly used routine films obtained at excretory urography was assessed in 565 patients. For a high level of confidence following films are recommended: Initial zonographic cut over the kidneys. A-P film covering bladder, ureters and as much as possible of the kidneys. Immediate post contrast medium injection film. Plain film or zonographic (tomographic) cut over the kidneys 10 min. later. Immediate post compression film. (Possible) post void film. The shorter urograms suggested by other authors are probably giving such a low level of confidence that other examinations may be requested as supplements.

A 16 deg. wedge pad for urography.

With the patient supine the long axis of the kidney has an average 16 deg. (SD 5,8 deg.) distal ventral inclination to the horizontal table top plane. A 100 cm long wedge shaped pad with a 16 deg. angle to be placed under the patient's shoulders and back during urography to bring the long axis of the kidney parallel to the horizontal plane is described. This method gives simultaneous good visualization of both the upper and lower outlines of the kidneys on a single tomographic cut.

[Reservations in the routine use of preoperative urography in colorectal carcinomas].

The diagnostic utility of preoperative intravenous urography (IVU) carried out in patients with carcinoma of the large bowel is still controversial. In the period between 1978 and 1984 only 8 out of the 347 patients undergoing surgery for carcinoma of the large bowel showed urinary tract involvement at operation. IVU had been carried out in 106 patients before surgery. The survey results agreed with histological reports in 103 case records: 101 true negative, 2 true positive. Two false positive cases and one false negative were also found. Among the eight patients who at surgery revealed urinary tract involvement, only in three IVU had been proposed; in the remaining 5 cases it had not been requested. It may be suggested that the early recognition of colon carcinoma does not allow the neoplasia to further develop in the urinary tract, at least not in as high a percentage as in the past. We therefore deem it necessary to use at first less invasive and faster methods, such as echography, limiting IVU to those cases where a well-grounded clinical suspicion or a previously executed echography suggest deeper investigation.

Transient gas-filled appendix developing during excretory urography.

Gas-filled appendix is well recognized in association with appendicitis, and in acute abdominal conditions associated with bowel distension. 3 patients who developed gas-filled appendix in the course of excretory urography are reported. The phenomenom is thought to result from the reported property of ionic contrast materials to produce anticholinesterase activity and histamine release, either or both of which could produce increased bowel tone and consequent displacement of cecal gas into the appendix.

Iohexol and ioxithalamate for intravenous urography. A comparative parallel study.

Omnipaque (iohexol) 350 mg I/ml has been compared with Telebrix (ioxithalamate) 380 mg I/ml in 48 patients undergoing intravenous urography. The contrast medium dose corresponded to 400 mg I/kg body weight. No cardiovascular reactions (BP and pulse rate) were observed. Subjective reactions occurred somewhat more frequently after Telebrix than after Omnipaque. Sensation of warmth was significantly less with Omnipaque (p less than or equal to 0.05). The overall radiological quality was equally good for the two contrast media.

[Risk of incompatibility reactions in the repeated use of contrast media in urography].

In a prospective study 260 urographies were evaluated regarding clinical compatibility. In altogether 11% of the patients mild incompatibility reactions were observed (heat sensation, urticaria, nausea, vomiting). 29% of the patients with known prior contrast agent incompatibility suffered from anaphylactoid symptoms mostly of a subjective type (heat sensation, nausea). There was no statistically significant difference in the frequency of objective symptoms (urticaria, vomiting) between patients with prior contrast media incompatibility (3%) and patients who had tolerated previous contrast media applications without symptoms (2%).

[The crescent sign in childhood urography].

The crescent sign is a rare roentgenological symptom in excretory urography of infantile hydronephrosis. The orign is a presence of contrast material in the collecting renal tubule of the atrophic renal parenchyma. That is displaced at the renal circumference. The disappearance of the crescent sign represents the prognostic for the reparative potence of the renal parenchyma after the therapy of the obstructive uropathy in two own case.

Benign transient eosinophilia following intravenous urography.

Eosinophilia, a component of the allergic response, may occur after the use of iodinated radiographic contrast media for intravenous urography. A benign transient elevation in differential eosinophil count was seen in 21 of 101 patients following the injection of iodinated contrast agents for that purpose.

Routine high dose excretory urography.

Radiologic evaluation of 316 excretory urograms utilizing a single 50 ml injection of a 50 to 60 per cent tri-iodinated contrast medium indicated that these studies are of better quality than those previously obtained with the injection of 30 ml. The low incidence of side effects coincides with recent reports in the literature that this dosage level is safe. High dose intravenous drip infusion pyelography was necessary only in selected cases. High dose excretory urography is recommended for routine use.

Excretory urography. A superfluous routine examination in patients with prostatic hypertrophy?

The problems about the value of excretory urography as a preoperative diagnostic examination in patients with benign hypertrophy of the prostate are discussed. On the basis of IVPs, renal function, and absence of hematuria and/or infection in 500 consecutive patients who were to undergo prostatic surgery, it is concluded that IVP is a superfluous examination. In patients with impaired renal function (Se-creatinine greater than 1.5 mg%) IVP showed abnormalities in 41.3%. In patients with normal renal function and urinary tract infection IVP revealed abnormalities in 20.6%. In patients with normal renal function and microscopic hematuria IVP showed abnormalities in 19.2%. It is thus concluded that IVP should be undertaken in patients with impaired renal function (Se-creatinine greater than 1.5 mg%) and may be considered in patients with normal renal function with hematuria or infection.

Preoperative evaluation of patients with bladder outlet obstruction with particular regard to excretory urography.

During the last 15 years excretory urography has been a routine preoperative diagnostic procedure for patients with bladder outlet obstruction in our department and, perhaps, for many more years in other urological centers. There are 2 reasons that this investigation should be done: 1) to detect abnormalities of the upper urinary tract that can be important indicators to operate or for the postoperative course and 2) to detect abnormalities in the bladder that should be corrected simultaneously with the prostatectomy or that can interfere with the procedure.

[Roentgen diagnosis of interstitial nephritis (pyelonephritis) by excretory urography and renovasography. Indications and diagnostic value of both methods including elektronic harmonization (author's transl)].

The roentgen signs of pyelonephritis may well be demonstrated by intravenous or infusion excretory urography. Discrete lesions of the calyces are better demonstrable by means of electronic magnification and harmonization. Inflammatory disease of the kidneys have characteristic patterns of vascular formation in renal arteriography. Electronic magnification and harmonization allow to detect initial stages of this illness.

Intravenous urography in children: is routine tomography useful?

We have evaluated the usefulness of routine nephrotomography in pediatric uroradiology. We reviewed all of the intravenous urograms done on children under 12 years of age, over a period of 18 months. In only 13 of 81 examinations (16%) was additional information obtained from tomography. It made no difference whether the patient could or could not cooperate during the study. In view of the cost of the extra films and the increase in radiation exposure, we therefore concluded that routine nephrotomography in pediatric intravenous urography is not indicated.
