[Clinical evaluation of vesicoureteroneostomy. II. Efficacy of surgery by Boari's method in eight and the psoas-hitch method in eight cases].

Vesicoureteroneostomy was performed by Boari's method on 8 patients and the psoas-hitch method on 8 patients during the 16 years from 1969 to 1986. Although Boari's method without the formation of a submucosal tunnel was employed for the initial 4 patients, the formation of this type of tunnel was a general principle for all patients thereafter. In choosing the surgical method, the psoas-hitch method was assigned to patients in whom it was possible to extend the urinary bladder to the upper part of the common iliac vessel and in whom the ureter allowed the formation of a submucosal tunnel, and Boari's method was assigned to those in whom it is was not possible to reach the ureter or to form a submucosal tunnel or in whom the ureter would be tensed. The mean length of the resected section of ureter was 75 mm for Boari's method and 43.2 mm for the psoas-hitch method. Follow-up observations revealed the presence of VUR in 2 patients who underwent surgery by the initial form of Boari's method and in 1 patient who underwent surgery by the psoas-hitch method. There was no ureteral stenosis or renal hypofunction in any of the patients.
