retrograde pyelography

Retrograde urography Imaging A method for visualizing the renal collecting system–ie, the pelvis and lower urinary tract, based on the excretion of radiocontrast after injection into the renal pelvis or ureter via a ureteral catheter Indications Suspected kidney disease–eg, pyelonephritis, kidney stones, or right upper quadrant colic

Traditionally, the diagnosis of duplicated renal collecting system and delineation of ectopic ureter orifices are made with ultrasound, IVP, retrograde pyelography, and cystoscopy.
The retrograde pyelography demonstrated duplicated renal collecting systems on the left and a fine developing degree of right lower pole moiety; it did not show the upper pole moiety on the right, which suggested that the ectopic ureter was on the right side and the ectopic orifice might be inserted extravesically.
Furthermore, the surgeon can do retrograde pyelography through a virtual ureteral catheter.
Adenocarcinomas of the stomach, lung, colon, pancreas and breast, in addition to lymphoma, sarcoma and carcinoids, have been repeatedly mentioned as causes of MRPF.[sup.1] The incidence of ureteral involvement in neoplasia is 0.2%.[sup.2] The phenomenon of MRPF is due to the ability of scirrhous tumours, such as adenocarcinomas, to produce an extracellular desmoplastic reaction.[sup.3] The increase in soft tissue density around the ureters on CT, the ureteral appearance on retrograde pyelography and the desmoplastic reaction seen on the histologic sections taken from the peritoneal implants suggest that distal bilateral ureteral obstruction in our patient was the result of MRFP.
The 2009 group included 49 patients identified with AKRI secondary to BUO confirmed by ultrasonography (US) and/or computerized tomography (CT); in 1982, most (48/50) patients were diagnosed with cystoscopy and retrograde pyelography.
The integrity of the upper urinary tract should also be evaluated with an intravenous pyelography, a retrograde pyelography or a pyridium test.[sup.10] A cystography may demonstrate a tract or retrograde filling of the uterine cavity.
Cystoscopy and retrograde pyelography were performed on the patient.
Upper urinary tract disease was assessed with CT and/or intravenous pyelography and/or retrograde pyelography. The distal ends of the ureters were sent for FS and later embedded in paraffin for subsequent permanent H&E sections.
