If retrograde pyelography
shows a transection or injury from a crushing clamp or sealing device, we recommend ureteroureteral anastomosis or urethral neocystostomy depending on the extent and location of the injury.
Reports show that many of these children have undergone extensive investigations such as magnetic resonance imaging, electroencephalography (EEG), intravenous pyelography
, small-bowel biopsy, and gastrointestinal barium swallow and some cases have been treated with antiepileptic agents before the establishment of a diagnosis.
The inclusion criteria: (1) All the patients were diagnosed definitely as unilateral upper urinary tract calculi before operation with a plain film X-rays and/or intravenous pyelography
and/or computer tomography (CT) scan.
Acute anuria following intravenous pyelography
in a patient with myelomatosis.
Radiological evaluation was performed with ultrasonography, intravenous pyelography
, and computed tomography scans.
The accuracy of noncontrast helical computed tomography versus intravenous pyelography
in the diagnosis of suspected acute urolithiasis: a meta-analysis.
We performed retrograde pyelography
to show the typical appearance of anterior crossing vessels.
Moreover, the anastomotic line was assessed for leakage with ascending pyelography
In our centers we developed the same protocol of fluoroscopic monitoring for the important moments of URS and uretero pyelography
, position check for the guide wire, control of residual/migrated fragments, and the final position of the double J catheter.
The kidney was scanned by fluoroscopy to exclude residual stone fragments followed by retrograde pyelography
with closure of Amplatz sheath to check the integrity of the pelvicalyceal system.
While intravenous pyelography
(IVP) has been used historically to define the anatomy of the urinary tract, it has failed to adequately demonstrate tumor masses in several reported cases of TCC in children (Hoenig et al., 1996; Rodriguez, Burday, Sexton, Ahmad, & Pow-Sang, 2005).
The marked pelvicaliceal dilatation and hydronephrosis in the obstructed kidney (so-called pale kidney) and also precise location of the obstructed/injured segment were observed via the standard intravenous pyelography
facilitated by contrast agents (Figure 1).
