[False image of renal artery aneurysm during intravenous urography. A previously unreported sign (author's transl)].

A rounded shadow of the renal sinus was observed, during the late vascular period of intravenous urography, in a true profile film of the kidney. Interpreted as being due to an aneurysm, a series of investigations were instituted, including more particularly angiography. It was finally demonstrated that the image corresponded to the segment of origin of a rectiliniar renal vein, seen axially. An observation of this type has not been previously reported, and raises certain questions on the practical attitude to adopt in such cases.

[Infusion urography in the topical differential diagnosis of tumors of the internal genitalia].

The results of studying the infusion urography findings in 64 patients with ovarian tumors and uterine fibromyomas indicated the possibility of using this method in the topic diagnosis of tumors of internal genitalia due to the effect of contrasting. Uterine fibromyomas are characterized by a homogenous accumulation of a contrast substance by the tumor. In ovarian neoplasms the effect of tumor contrasting is frequently absent. In a number of cases it is of a nonhomogenous character (the symptom of a "rim or "border").

[Acute renal failure following intravenous urography. 4 cases (author's transl)].

The authors report on 4 cases of acute oligo-anuric renal failure that followed intravenous urography (IVU) independently from myeloma or cardiovascular collapse. Eighty other cases can be found in the literature. Post-IVU renal failure only occurs in patients already presenting with chronic renal insufficiency, those with diabetic or geriatric arterial disease being particularly at risk. It is reversible in only one out of two cases when serum creatinine levels exceed 440 mumol/l. The various triiodide contrast media with a high osmolality are equally nephrotoxic. The pathophysiology and prevention of this complication of IVU are discussed.

[Anaphylactoid shock during intravenous urography. Possible interaction between complement and fibrinolytic systems (author's transl)].

Shock associated with deep coma was induced by an injection of methylglucamine iodotalamate for descending urography to a 56-years old man without any history of atopy. Under intensive care the acute symptoms were controlled, and consciousness returned to a normal level within 15 days, but the patient remained with right-side monoplegia. Biological investigations showed a fall in total haemolytic complement (CH50) and in C1, C4, C2 and C3 components, as well as in B-factor. Acute fibrinolysis and hypocalcaemia were also present. Two main mechanisms seem to be responsible for the accident : intolerance to the drug, with direct activation of the complement and fibrinolytic systems ; and an immuno-allergic reaction where the contrast medium behaved like an hapten, which became antigenic in the body.

[MR urography with the T2-weighted turbo-spin-echo sequence].

Tumor-induced dilatation of the urinary tract is difficult to diagnose in the distal part of the ureter, including the stenosis, by ultrasound and X-ray. Often on account of renal insufficiency and allergy, i.v.-contrast media cannot be used. The present study should show the suitability of fast T2-weighted (turbo-) spin-echo sequences (T2-TSE) for MR-urography (MRU). Seven patients (62.3 +/- 6.1 years) were examined in the coronal plane with T2-TSE sequence (TR = 4500 ms, TE = 160 ms) and an MRU was calculated by using the MIP method (maximal intensity projection). This technique enabled urogram-like morphological representation of dilated urinary tract including stenosis in 6 of 7 patients. Assuming a high magnetic field homogeneity, MRU by using a T2-TSE-sequence, without i.v.-contrast media administration, can visualize the urinary tract dilatation and localize tumor-induced stenosis.

[Correlation of urography, ultrasonography and computer tomography with clinical findings in examinations of the kidneys and retroperitoneum. Possibilities of diagnostic errors].

The authors prospectively and retrospectively mutually compared the diagnostic value of urography, ultrasonography (USG), and computer tomography (CT) in four patients, with the diagnosis misstated prior to operation. The most valuable findings were provided by CT. Mere utilization of these methods does not exclude the possibility of diagnostic misstatements. In three patients the ultimate diagnosis was assessed on the basis of operative revision and in one patient, by means of cytologic examination of the renal punctate. Owing to retrospective evaluation of examinations, diagnostically valuable symptoms which could have lead to the correct diagnosis, were distinguished. Hence, examinations must necessarily be evaluated in complex with the general clinical state. (Fig. 6, Ref. 14.).

Measurement of plasma contrast levels during excretory urography.

Ultraviolet spectrophotometry permits easy measurement of plasma levels of intravenously injected contrast media. The initial results are described from the determination of plasma methylglucamine iothalamate (Conray 60) levels during routine excretory urography in 10 normal patients. This simple procedure has many potential applications in the investigation of contrast media physiology.

[Study of children with urinary tract infections. Does intravenous urography play any role?].

Ninety children referred to hospital with urinary tract infections (UTI) were investigated by intravenous urography (IVU), ultrasonography (US) and 99m-Tc dimercaptosuccinic acid scan (DMSA). Fifty-eight children also had a micturition cystourethrography performed. In 36 (40%) of the children at least one result was abnormal. In 29 children IVU was abnormal, 10 had abnormal US and 16 had abnormal DMSA. Six of the 58 children had vesicoureteric reflux in eight kidneys. In 16 children IVU was the only examination with an abnormal result, and in ten of these the findings were considered important for treatment or prognosis. In conclusion, IVU is an important supplement to US and DMSA in investigation programs for children with UTI. IVU should be performed in cases of renal scarring or dilatation and in children with recurrent infections.

[Gonadal dosis in intravenous urography and voiding cystourethrography of children (athor's transl)].

Measurements of gonadal doses of 92 children during intravenous urography and voiding cystourethrography are reported. The high deviation of doses in the testes is discussed. The application of a lead protector for the testes is demanded to decrease exposure by a factor 15 in the central beam and a factor 1.3-2 in scattered radiation. By choice of spot film radiography instead of large radiography the ovarian dose is reduced to a factor 7-40. The gonadal dose is clearly lower if 70 mm technique instead of large film technique is used. A correlation between area ionisation product and gonadal dose could not be found; therefore the genetic radiation dose cannot be calculated by data recorded as required by law.

Post-voiding roentgenograms in routine intravenous urography.

57 patients were studied to determine the validity of post-voiding films in routine urography. It was discovered that if the post-voiding film was delayed by as much as five minutes after the patient had actually voided, a significant error was introduced. The post-voiding film must therefore be obtained immediately after voiding and even a short delay, which is not uncommon in busy Radiology Ddepartments, may result in a false impression of incomplete voiding.

Is routine excretory urography necessary at first diagnosis of bladder cancer?

PURPOSE: We determined whether routine excretory urography (IVP) at initial diagnosis of bladder cancer is useful in screening the upper urinary tract for clinically inapparent urothelial tumors. MATERIALS AND METHODS: IVPs and ultrasound findings of 314 patients with bladder cancer were reviewed retrospectively. RESULTS: Only 1 silent upper urinary tract tumor was detected with IVP (0.3%), resulting in nephroureterectomy. IVP had no further therapeutic consequences except for destruction of an asymptomatic prevesical stone. IVP was followed by ureterorenoscopy in 5 patients with negative results. Upper urinary tract obstruction could be documented equally well by sonography in all cases. CONCLUSIONS: Routine IVP at first diagnosis of bladder cancer is unnecessary.

[In adult urology, when should ultrasonography, computed tomography, intravenous urography be requested?].

The authors recall the indications for the medical imaging examinations most frequently used in adult urology, depending on the organ, syndrome or disease to be investigated. The indications for intravenous urography (IVU) are increasingly rare, but it remains the reference examination to study the pyelocaliceal cavities. Ultrasonography, combined with KUB, generally provides a diagnosis, especially in the emergency setting. Computed tomography (CT) is the reference examination for the investigation of all types of renal lesions, but also lesions of other organs, especially in the case of neoplastic disease.

Excretory urography before prostatectomy.

A study of the pre-operative excretory urograms of 205 patients who had prostatectomy for benign prostatic hyperplasia, over a 5-years period is presented. Seventy-four per cent (74.1%) of the urographic abnormalities were a direct result of prostatic enlargement found on clinical examination. The significant upper tract abnormalities found in 11.0% of the cases were duplex kidneys (3.4%), poor renal excretion (3.8%) and small kidneys (3.8%). None of these was a contraindication to prostatectomy when the blood urea and creatinine levels became normal. No upper tract tumour nor calculus was found in these patients. We conclude that, for the management of patients presenting with urinary retention from BPH, routine pre-operative excretory urography has little or no value and is not worth the expense and delay.

[Study of immunological parameters in radiography and excretory urography].

Some immunological parameters (levels of serum complement, content of circulating immune complexes, and serum concentrations of immunoglobulins) were examined in patients after excretory urography by using triombrast and after X-ray studies without applying any contrast substance. Some changes were found in the activity of complement and in the concentration of immunoglobulins following intravenous triombrast injection. In addition, the above parameters were evaluated in patients with adverse reactions during the contrast study. The findings are discussed in terms of the immunotropic effects of triombrast.

[Imaging studies of excretory urography and computed tomography scan for patients suffering from renal colic].

Renal colic mainly due to urolithiasis is one of the most common morbid conditions in urology and commonly seen in the urology emergency clinic. Imaging studies were performed to evaluate the upper urinary tract of 29 patients suffering from renal colic in the 2 years between November, 1994 and October, 1996. After intramuscular injection of the analgesic (pentazocine, 15 mg), all 29 patients were examined by excretory urography (IVP) at the time of the first visit. In some patients abdominal plain computed tomography (CT) scan was performed consecutively even when extravasation of the contrast medium was not seen. Spontaneous peripelvic extravasation was seen in 14 patients (11 males and 3 females) with urolithiasis; 7 of them were diagnosed by IVP, 5 by IVP plus CT scan and 2 with CT scan only. IVP imaging study followed by plain abdominal CT scan is useful even when the contrast medium is not extravasated on IVP in patients suffering from renal colic.

A comparison of noncontrast computerized tomography with excretory urography in the assessment of acute flank pain.

PURPOSE: We compare noncontrast enhanced computerized tomography (CT) and excretory urography (IVP) in the evaluation of acute flank pain. MATERIALS AND METHODS: A total of 40 consecutive patients presenting to the emergency department with acute flank pain were evaluated with noncontrast CT, films of the kidneys, ureters and bladder, and IVP. The patients were treated according to the clinical picture. All 40 sets of evaluations were later assessed randomly by an independent consultant radiologist for the presence, size and location of a stone, ureteral dilatation and secondary signs of ureteral obstruction. RESULTS: Of 40 patients 12 had no calculus and 28 had a calculus confirmed on removal or documented passage of a stone. Absence of a stone was based on clinical and radiological followup with clinical resolution. CT revealed all 28 calculi and no calculus in 11 of 12 patients with 100% sensitivity and 92% specificity. IVP demonstrated 18 calculi (64% sensitivity) and no calculus in 11 of 12 patients (92% specificity). Ureteral obstruction was seen in 28 of the 40 patients, and CT and IVP were equivalent in detection (100% sensitivity). Films of the kidneys, ureters and bladder alone demonstrated 15 of 28 stones (54% sensitivity). CONCLUSIONS: Noncontrast CT is an accurate, safe, rapid technique to assess acute flank pain, and the evaluation of choice for patients who would otherwise require IVP for diagnosis.
