Computed tomography of ureteral obstruction [PDF]

American Journal of Roentgenology, 1982
Although hydronephrosis can usually be diagnosed by urography and/or pyelography, the etiology of the obstruction may not be apparent. Computed tomography (CT) is usually helpful in evaluation of these cases. In 36 cases in which CT was performed solely to determine the cause of ureteral obstruction of uncertain etiology, it proved to be of value in 33

The Pathophysiology of Ureteral Obstruction

Journal of Endourology, 1993
Ureteral obstruction can have a variety of causes intrinsic or extrinsic to the kidney. The effects of obstruction are examined from the perspectives of duration, severity, totality, and the presence of complicating factors. There is a difference in the postobstructive pathophysiology depending on whether one or both ureters were obstructed.

Procidentia and Ureteric Obstruction

British Journal of Urology, 1975
Summary3 cases of renal failure, due to procidentia, presenting as emergencies are described. The upper urinary tracts of 4 asymptomatic patients with procidentia were investigated; dilatation was found in 1 instance only.We would like to thank Miss A. Bigby and Mr Harron Thomson for allowing us to study the latter cases in this presentation, also Dr D.

Unilateral ureteral obstruction: beyond obstruction

International Urology and Nephrology, 2013
Unilateral ureteral obstruction is a popular experimental model of renal injury. However, the study of the kidney response to urinary tract obstruction is only one of several advantages of this model. Unilateral ureteral obstruction causes subacute renal injury characterized by tubular cell injury, interstitial inflammation and fibrosis.

Transient Ureteral Obstruction After Ureteral Stenting

Journal of Urology, 1982
Transient distal ureteral edema and obstruction have been recognized complications of retrograde ureteral catheterization for years. Similar changes in the proximal ureter may be induced by antegrade (percutaneous) ureteral intubation and are being more widely recognized as radiologists become more involved in upper urinary tract percutaneous ...

Tandem Ureteral Stents for Malignant Ureteral Obstruction

Journal of Endourology, 2020
Objectives: Malignant ureteral obstruction (MUO) is a devastating complication of cancer, and it is commonly treated by drainage via percutaneous nephrostomy (PCN). The objective of this study was to determine the efficacy, safety, and functional outcome of tandem ureteral stents (TUS) in the management of MUO.

Ureteral Stasis in Cervicoprostatic Obstructions

European Urology, 1980
A urodynamic study of patients with prostatic adenoma or other types of cervicoprostatic obstructions demonstrate that ureteral stasis is not a consequence of a direct compression of the intramural ureter by the adenoma but is secondary to dynamic disturbances.

Bilateral Ureteral Obstruction

JAMA, 1964
Dr. Dale E. Wenlund: This 63-year-old man was well until about one and a half years prior to the present admission, when he had a cholecystectomy. He subsequently noted a painful bulge in the region of the subcostal scar. Because of pain and anorexia, he lost 30 lb (1.36 kg) during the next 18 months and was unable to work.
