Spontaneous renal calyceal and ureteric rupture secondary to intravenous contrast during computed tomography intravenouspyelogram Upper urinary tract rupture in the absence of trauma is typically related to ureteric calculi causing obstructive nephropathy. Spontaneous extravasation of contrast during CT intravenous pyelography (CT IVP) is infrequently reported. Two cases, who underwent CT IVP
Guy's Stone Score (GSS) Based on IntravenousPyelogram (IVP) Findings Predicting Upper Pole Access Percutaneous Nephrolithotomy (PCNL) Outcomes To predict the success rate and complications following percutaneous nephrolithotomy via the upper pole using the Guy's Stone Score (GSS) based on the findings of a preoperative intravenouspyelogram (IVP). . Two hundred and twenty-seven renal
Imaging the urologic patient: the utility of intravenouspyelogram in the CT scan era. An opportunity exists to evaluate the quality of care in patients undergoing intravenouspyelogram (IVP) imaging and to define the role of IVP in the computed tomography scan era. Medical records were reviewed for patient demographics, inpatient versus outpatient setting, indication for IVP, physician
urothelial carcinomas may present with pain resulting from obstruction by the tumor.Urothelial carcinomas are often multifocal—the entire urothelium needs to be evaluated if a tumor is found. In patients with bladder cancer, upper urinary tract imaging is essential for staging and surveillance. This can be accomplished with ureteroscopy, retrograde pyelograms during cystoscopy, intravenouspyelograms
anatomy, such as an ultrasound, CT scan and intravenouspyelogram (IVP). Lower tract evaluations include video/urodynamics to determine bladder and sphincter function, cystograms to evaluate for vesicoureteral reflux and cystoscopy to evaluate bladder anatomy.• It should be noted that an urodynamic study (UDS) is an important evaluation for determining bladder function and should be performed after
. Radiography Intravenous Urography There is limited evidence to support the use of radiography with IV urography (IVU) (also referred to as IVpyelogram [IVP]) for initial imaging of patients with asymptomatic unilateral hydronephrosis with unknown cause. US Abdomen There is relatively limited evidence to support the use of US of the abdomen for initial imaging of patients with asymptomatic
compared with KUB alone or intravenouspyelogram (IVP) (conditional recommendation and low certainty)Recommendation 4: For pregnant patients or children suspected of renal colic, the panel suggests abdominal USG compared to NCCT or other imaging modalities (conditional recommendation and low certainty).Explanation: The panel placed a higher value on reducing radiation exposure and a lower value
be appropriately investigated with kidney/bladder ultrasound. * In most cases, kidney/bladder ultrasound is the preferred initial investigation. * Kidney/bladder ultrasound and computed tomography intravenouspyelogram (CTIVP) are often used to evaluate the upper urinary tract of patients with microscopic hematuria. * Traditional intravenouspyelogram (IVP) is still a valid test, however, it is no longer . 2. Computed Tomography IntravenousPyelogram (CTIVP)Strengths: detection of renal calculi, small renal and pararenal abscesses, small renal tumors, upper tract urothelial tumors. Limitations: high cost and limited availability in some areas, equivalent to 2-3 years background radiation exposure. Note: CTKUB (non contrast CT) and single phase contrast enhanced CT (CT abdomen
on a combination of radiographic procedures (e.g., intravenouspyelogram and computed tomographic scans) and, more recently, ureteroscopy and biopsy.The advent of rigid and flexible ureteroscopic techniques has permitted endoscopic access to the ureter and renal pelvis. This may permit greater accuracy in preoperative definition of the stage and grade of an upper tract neoplasm. In addition, fulguration
. (Clinical Principle) Discussion × DiscussionCT scan of the abdomen and pelvis, using IV contrast with immediate and delayed phases is preferred in order to elucidate both the location of renal lacerations and the presence of contrast extravasation from collecting system injuries. Standard intravenouspyelogram (IVP) may be used in rare cases where CT is not available, but is inferior. Ultrasound may
