Intra- venous urography
infrequently demonstrates exist- ence of a fistula due to poor function of the affected kidney.3 In fact, a large number of these fistulae have been demonstrated radiographically, with oral contrast examinations such as CT and upper gastrointestinal series.
(IVU) study showed bifid pelvicalyceal systems bilaterally.
Imaging studies such as computerized tomography (CT) and retrograde urography
are helpful for identifying a carcinoma in the ureter.(2) Jaffe et al.(3) have shown the feasibility of CT and MRI for the early diagnosis of a ureteral stump tumor.
Patients and Methods: All patients who had renal calculi up to 2.5cm in size were selected for extra corporeal shock wave lithotripsy with Dornier MPL 9000 on the basis of clinical examination, laboratory investigations, X-Ray, intravenous urography
Historically, retrograde or intravenous pyelography had been the radiologic procedure of choice for the diagnosis of reno-alimentary fistula but CT urography
which is widely available today is a much more rapid and easier alternative.
UPJO in solitary kidney with intrarenal pelvis was detected in urography
images by CT scan (Figure 1).
provides a detailed anatomic depiction of the entire urinary tract in a single breath hold, thus allowing patients with haematuria to be evaluated comprehensively.
further possible application areas: - urography
, - computed tomography, - angiography, - digital subtraction angiography (dsa), - angiocardiography, coronary arteriography, interventional coronary arteriography, - fistulography, galactography.
Hemogram, coagulation profile, serum electrolytes, glucose, serum creatinine levels, urinalysis and urine culture, liver function tests, ultrasonography and intravenous urography
and CT urography
(In selected patients) were performed before the patients underwent PCNL.
Various imaging modalities are currently employed for determining the extent of carcinoma cervix including ultrasound, barium enema, intravenous urography
, computed tomography (CT), PET and MRI.
has been used to evaluate microscopic hematuria in the past, but now it is not preferred due to its low sensitivity (3).
A diagnosis of UPJ obstruction is made based on a CT urography
or intravenous pyelography with a typical appearance of a large pelvis with a high-riding ureter in the pelvis.
