[The psoic bladder or Boari's knell. 4 cases (author's transl)]

Repairing a pelvic ureter is always an ideal when the kidney above it is still functional. But this operation imposes technical artifices when direct urtero-vesical implantation is not possible. Referring to four cases, the authors show the value of the psoic bladder and compare it with the tubulate vesical strip and vesical bipartition.
