Diagnosis-based segmentation of the kidney stone market comprises ultrasound, intravenous pyelography (IVP) or intravenous urogram, CT scan and X-ray.
The diagnosis is carried by general ultrasound, urinalysis, intravenous pyelography. The chronic pyelonephritis treatment varies with patients who reports more pain than others with suitable treatment types.
Retrograde pyelography is performed with the C-arm at 0-degree angle to delineate the intrarenal collecting system and exact location of the stone(s).
He was readmitted to hospital and arranged for cystoscopy and left retrograde pyelography, which confirmed urine extravasation from an interpolar calyx.
On the second day, antegrad pyelography showed passage to the bladder without extravasation.
Diagnosis via imaging has traditionally been by antegrade pyelography, and more recently clinicians have begun to utilize CT intravenous pyelography.
The incidence of fusion anomalies appears in three age groups: in small children HSKs are diagnosed as part of a combination of malformations, in young adults during diagnosis of delayed menarche as a part of Turner syndrome (Glodny et al., 2009), while detection of HSK in adults is incidental during routine radiological procedures (transabdominal ultrasounds, computed tomography or intravenous pyelography) performed on them for other reasons.
This ureteric catheter is used to perform realtime fluoroscopic contrast and/or air pyelography; which helps in making the puncture accurately into the intended calyx.
Radiography, intravenous pyelography and radionuclide studies are not preferred in routine practice for the evaluation of neonatal kidneys due to radiation risks and difficulties in application.
the system is used in particular for transurethral (eg transurethral resection of bladder tumors, transurethral resection of the prostate, cystoscopy, double j-abutment, ureterorenoscopy) and percutaneous (eg percutaneous nephrostomy, percutaneous nephrolithotripsy) surgeries, as well as videotropic examinations and radiographic-urological (eg, abdominal overview imaging, iv pyelography, retrograde pyelography, retrograde urethrography, micturition cystourethrogram) and pediatric x-ray examinations.
Following the discovery of various contrast materials that could be installed into the urinary tract, new applications were introduced, including cystography in 1903 and retrograde pyelography in 1906 [1].
