INTRODUCTION: The effects of dilatation and increased pressure in the ureter and renal pelvis following ureterorenoscopy (URS) are not well documented. The purpose of the prospective study was to ...

Prenatal Hydronephrosis (PNH) is caused in fetal infants identified by obstruction in the urine production, it leads to the enlargement of the kidney in fetal infants. Hydronephrosis is a common ...

The excretory urogram revealed less than the normal physiologic dilatation of the renal pelvis, with prompt excretion and good concentration of the radiopaque material . It is of ...

In contrast, animal studies showed relative safety when exposure was during early gestation, whereas exposure in later in pregnancy was associated with dilation of renal pelvis and tubules.

• 50081: Percutaneous nephrolithotomy or pyelolithotomy, lithotripsy, stone extraction, antegrade ureteroscopy, antegrade stent placement, and nephrostomy tube placement, when performed, including ...

Diuretic renal scintigraphy plays a critical diagnostic role by providing a physiologic means for differentiating between obstructive and nonobstructive hydronephrosis and by assessing the function of ...

Diuretic renal scintigraphy is critical in differentiating between obstructive and nonobstructive hydronephrosis. Under physiologic conditions, urine may pool in the renal pelvis during hydronephrosis ...

These new CPT codes were 50436 (dilation of existing tract, percutaneous, for an endourologic procedure including imaging guidance [eg, ultrasound and/or fluoroscopy] and all associated radiological ...

Results: Renal scintigraphy of 41 hydronephrotic patients validated that 19 patients had non-obstructive bilateral pelvic dilation while the remaining 22 with mild to severe obstruction.

Having straight access to the renal pelvis allows uncomplicated passage of the guide-wire down the ureter, increasing the safety of subsequent tract dilation. Moreover, over-passing the calyces opens ...
