Concomitant MAZE procedure during cardiac surgical procedures: is there any survival advantage in conversion to sinus rhythm?
The surgical MAZE procedure has a high conversion rate, however, our data did not show improved survival in patients who converted to SR prior to discharge.
The fate of severe megaureter seems strongly influenced by congenital renal damage secondary to a developmental abnormality of the ureteric bud. A poor resolution rate has to be expected in these cases; surgery must be reserved for symptomatic cases but has no influence on pre-existing renal damage.
