  • Title: Pre- and postoperative urographic findings in posterior urethral valves.
    Author: Eklöf O, Ringertz H.
    Journal: Pediatr Radiol; 1975 Nov 24; 4(1):43-6. PubMed ID: 1233454.
    Abstract:
    In a series of 65 male infants and children, all with the diagnosis of posterior urethral valves, pre- and postoperative urographic findings were reviewed. In addition changes occurring in the bladder, and the implication of vesico-ureteral reflux were assessed.--Preoperatively diagnosed impairment of kidney function and concommitant dilatation of the upper urinary tract, with some exceptions. Remained fairly unchanged at postoperative examinations In the case of marked vesico-ureteral reflux, permanent kidney function annihilation was significantly commoner than with slight or no reflux.--Although, as a rule, both the upper urinary tract and the bladder were affected, there were cases of posterior urethral valves with a normal appearing bladder. As the intravenous urography do not exclude the urethral abnormality, voiding cysto-urethrography has to be included in the primary radiological exploration of all cases with urological problems. Key words: Intravenous urography, non-functioning kidney, upper urinary tract dilatation, voiding cysto-urethrography, posterior urethral valve, bladder outflow obstruction.
