Ureteric Obstruction
Observe the obstructive lesion near the lower end of the right ureter. On simultaneous retrograde examination, the lower margin of the obstructing lesion is clearly demarcated.
Intravenous pyelogram
Intravenous pyelogram (IVP) (1 hour post-dye injection) showing right hydronephrosis, hydroureter, dilated renal pelvis and calvx.
UPJ Obstruction
Congenital UPJ Obstruction & Hydronephrosis
Congenital utero-pelvic junction (UPJ) obstruction & hydronephrosis. This image demonstrates severe hydronephrosis of the right kidney. Retrograde pyelography demonstrates an obstruction at the UPJ. The obstruction in this patient was congenital.
Stone CT
Non-contrast CT for renal colic.
Left Image: shows right-sided pelvicaliectasis relative to the left-sided renal collecting system.
Right Image: shows calculus in the distal right ureter as the cause.

Hydronephrosis
Hydronephrosis of left kidney on ultrasound caused by a left upper ureteric stone seen on abdominal X-ray (red arrow).
Renal Angiograms
Left Image: Normal renal arterogram.
Right Image: Renal artery stenosis. This is a renal angiogram demonstrating renal artery stenosis of the left renal artery
Peyronie’s Disease
Peyronie’s Disease is a fibrous cavernositis. The disease begins as a fibrous area which gradually thickens and extends along the shaft of the penis inconfluence or as separate fibrous plaques. Calcification is not infrequent. Also note the transcervical fracture of the left hip.
Kidneys
Polycystic kidneys in newborn
Intravenous Pyelograms
Left Image: Normal intravenous pyelogram. The relevant anatomy is labeled on the image.
Right Image: Left bifid ureters. This is an IVP demonstrating bifid ureters on the left side.
Cystitis
Cyclophosphamide Induced Cystitis
Cyclophosphamide induced cystitis. This patient presented with gross hematuria after recent treatment with cyclophosphamide. Cyclophosphamide is excreted by the kidney. The direct contact with the bladder mucosa leads to cystitis. Approximately 10% of patients on this drug have this complication. The figure rises to 40% for those patients receiving high-dose treatment.
