CONGENITAL URETERAL VALVE

Abstract

The congenital ureteral valve, which rarely occurs, constitues a primary cause for the obstruction of the upper part of the urinary tract. However, the origin of its developement is still unaccounted for.
The literature has supplied us with only ten cases of this deformity. The purpose of this paper is to present additional three cases.
Case NO. 1: The patient, a 24-years old male, had valve in his right ureter. He had, in addition, right hydronephrosis of moderate degree and ureteral calculus.
Case No. 2: The patient, a 29-years old female, was found to have duplicated left kidneys, one of the duplicated ureters having valves. There was hydronephrosis of severe degree above those valves.
Case No. 3: The patient, 57-years old female, had valves in the right ureter and hydronephrosis of severe degree in the right kidney.
Nephroureterectomy was performed on the above three patients with rather satisfactory results.
