[Surgical treatment of ureterocele]

From 1971 the authors operated on 6 patients with ureterocoele type B (Uson), using a modified Hutch-Chisholm method. Following the removal of the ureterocoele and reconstruction of the detrusor muscle, the hiatus of the ureter and the vesicular wall, the ureter is placed on the reconstructed muscle whereas its free end is fixed to the trigone. Covering the ureter with vesical mucosa is not necessary; in cases with large ureterocoeles that is not even possible. The regenerative capacity of the vesical mucosa is great and rapid and covers the intravesicular part of the ureter without causing damage to the ureteral orifice or to its valvular function. In all 6 patients the results were good at the control examination 3 to 6 years postoperatively.
