    Which common purpose is served by both cystoscopy and retrograde pyelography tests? items. If you are uncertain about a question, eliminate the choices that you believe are wrong and then call on your knowledge, skills, and abilities to choose from the remaining responses. What diagnostic tools are used to locate the position of renal calculi? retrograde pyelography and cystoscopy: stones in the renal pelvis can be extremely painful and cause _____ whith their sharp surfaces. tissue trauma: A nephrostomy tube may be placed in the _____ for drainage. renal pelvis: What incision will give good kidney exposure.

    The _____ bulb or cone-tip catheter is used to occlude the ureteral orifice during imaging studies when a contrast medium is injected during retrograde pyelography.   Percutaneous surgery is based on needle and guidewire access to the kidney and the upper urinary tract. Once guidewire access is obtained, various catheters can then be placed into the kidney, either for drainage or for facilitation of antegrade intrarenal or ureteral endoscopic procedures.

    urolithiasis. Although ultrasonography is readily available,quickly performed and sensi-tive to renal calculi, it is virtually blind to ureteral stones (sensitivity: 19 percent), whichCited by:   Intravenous urography is a test that uses X-rays and a special dye to help assess your kidneys, ureters, bladder and urethra..

Renal catheterization and pyelography will usually differentiate. In the absence of renal infection, a high leucocyte count will perhaps indicate appendicitis. The general practitioner will be the one whom the patient calls to relieve the agony of an attack of renal colic.

Upper urinary tract rupture during intravenous pyelography resulting in extravasation of contrast from the pelvicalyceal system and ureter is rarely described. 1 2 The majority of cases in the literature of spontaneous renal calyceal rupture or ureteric rupture in the absence of trauma are related to ureteric calculi and other uncommon aetiologies such as malignancy, pregnancy, posterior urethral valves, Author: Tatenda Calvin Nzenza, Derek Barry Hennessey, Tim Dunshea, Nathan L Lawrentschuk.

Intravenous urography (IVU), also referred to as intravenous pyelography (IVP) or excretory urography (EU), is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and the urinary exam has been largely replaced by CT urography.

Terminology. Some prefer the term "urogram" to refer Pyelography during operation for renal calculus book visualization of the kidney parenchyma, calyces, and pelvis after. Ureter could be catheterized to only 3 cm. PERFORATION OF URETER DURING RETROGRADE PYELOGRAPHY COMMENTS With the increased use of retrograde pyelog raphy in the diagnosis of urinary tract diseases, there has been a concomitant increase in the number of cases of traumatic perforations of the ureter and renal by: 8.

the open operation to treat renal calculi gradu-ally []. We used percutaneous nephrolithoto - my (PCNL) to treat renal calculus which the diameter was larger than 2 cm [4].

While with the increasing complete clearance rate of renal calculi, the complication rate of the treatment also increased. To solve this problem, two kinds. Two weeks after operation, anterograde pyelography through the nephrostomy tube was performed (Fig. 9) which did not show hydronephrosis, and compression in the right kidney and tube was still inside the renal sinus, cyst cavity was not noticed and the shape of the calyx had become normal.

After this, the double J stent was removed by ureteroscopy, and patient had no discomfort after stent by: 1. Renal calculi or renal stones consist of aggregates of crystals and small amounts of proteins and glycoproteins.

Different types of stones occur in different parts of the world. Studies have shown that 4% of the total population has stones in the urinary tract. Aetiology The exact aetiology is unknown, the various predisposing factors may be.

Surgery Surgery may be indicated for recurrent UTI if diagnostic test-ing indicates calculi, structural anomalies, or strictures that contribute to the risk of infection. Table 26–1 lists major causes of urinary tract obstruction that may contribute to UTI.

Client and Family Teaching •The bladder is filled with dye solution and X-rays are takenFile Size: 63KB. When only 1 kidney was involved, the risk of left renal calculus was greatest for both dogs and cats, but bilateral renal involvement was relatively common in both species (19% and 9%, respectively).

the renal pelvis and allowing part of the opaque solution to drain away; some of the solution may adhere to the calculus and cast a shadow. Shadows near the Line of the Ureter.?Extraureteral shadows can be differentiated by ureterography during pyelography, owing to the presence of some sodium iodide in the lumen of the ureter.

Intravenous Pyelography (Pyelogram) (IVP) – test to visualize the kidneys, ureters, and bladder. A radiopaque substance is intravenously injected, and x-rays are taken.

Abnormal results can indicate renal calculi, kidney or bladder tumors, and kidney disease. KUB (Kidney, Ureter, Bladder) – flat-plate x-ray taken of the abdomen. Staghorn calculus almost comprises of entire caliceal system and pelvis.

It jeopardises the function of the kidney. Intravenous pyelogram is used to detect the excretion pattern of the kidney.

Of these 15 patients, 5 were diagnosed perioperatively and 10 were diagnosed postoperatively. Of the colon injuries, 66% occurred during left-sided PCNL procedure and 34% occurred in right-sided PCNL procedure. In right-sided injuries, all patients had horseshoe kidney or previous history of renal by: 4.

Retrograde Pyelography. Retrograde pyelography is performed when the ureters are poorly visualized on other imaging studies or when samples of urine need to be obtained from the kidney for cytology or culture. Patients who have severe allergies to contrast agents or impaired renal function can be evaluated with retrograde pyelography.

When a renal calculus is branched, there is no doubt concerning the shadow it casts. X-rays usually confirms 90% of the renal stones except the pure uric acid stones.

When a stone is found, exposures are made during full inspiration and full expiration to see whether the stone moves slightly with the kidney during respiration. (a) KUB radiography reveals a lower pole renal calculus in the left kidney.

(b) Intravenous pyelography shows the calculus causing dilatation of the upper calyx. An intravenous pyelogram (IVP) is a type of X-ray that looks at your kidneys and bladder and the ducts (ureters) that connect them. It’s not used very often.

Other imaging tests, like CT scans. Staghorn calculus. (a) Plain film radiograph (inverted image) demonstrates staghorn calculus (arrow) in the right kidney. (b) Retrograde pyelography reveals staghorn calculus involving the middle and lower pole calyces of the right kidney.

(c) Nephrectomy specimen, bivalved, from a patient with recent sepsis and nonfunctioning kidney. Reasons for performing a retrograde pyelogram include identification of filling defects (e.g.

stones or tumors), as an adjunct during the placement of ureteral stents or ureteroscopy, or to delineate renal anatomy in preparation for surgery.

Retrograde pyelography is generally done when an intravenous excretory study (intravenous pyelogram or contrast CT scan) cannot be done because of renal ICD An intravenous pyelogram (IVP), also called an intravenous urogram (IVU), is a radiological procedure used to visualize abnormalities of the urinary system, including the kidneys, ureters, and a kidneys, ureters, and bladder x-ray (KUB), which is a plain (that is, noncontrast) radiograph, an IVP uses contrast to highlight the urinary code: d  Renal vein thrombosis (RVT) with flank pain, and hematuria, is often mistaken with renal colic originating from ureteric or renal calculus.

Especially in young and otherwise healthy patients, clinicians are easily misled by clinical presentation and calcified RVT. A year-old woman presented with flank pain and hematuria suggestive of renal calculus on by: 2.
