Abstract:
Congenital midureteric obstruction is a rare entity which can be caused by either ureteric valves or strictures. We report our experience with four patients with midureteric obstruction due to stricture over a six-year period. The condition needs to be differentiated from obstruction of the pelviureteric and vesicoureteric junctions. Obstruction can be initially screened by ultrasound and confirmed by a radionuclide scan with furosemide challenge. Retrograde ureteropyelography and/or intravenous urography may be required to define the level of the stricture.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
