Bladder-flap plasty in disturbances of urine transport.

Abstract

Late results of the bladder-flap method Boari--Mezö fulfilled expectations only in the correction of ureteral lesions of gynaecological origin. With appropriate technique even 5 to 10 cm long sections of the ureter can be replaced and in one-third of the cases the late results, too, are good. The authors are convinced that Boari plasty is not an anti-reflux operation and the results are poor in cases of specific ureteral stricture. The operation is recommended for the correction of congenital malformations, fibrous periureteritis and strictures after nephrolithotomy when the strictures are long and simple ureteral neoimplantation is technically impossible.
