[Ureteroureterostomies: indications and results (author's transl)].

Thirteen unilateral ureteroureterostomies and twenty-five transureteroureterostomies (TUU) were performed since 1968. In 22 of these, a transureteroureterocutaneostomy (TUUC) was done. Indications, operative procedures, results and complications are discussed. No complications due to the anastomosis were found. In six cases stenosis of the ureterocutaneostomy was demonstrated which, in four instances, made another form of urinary diversion necessary. Ureteroureterostomies should only be performed with well functioning kidneys and with one well preserved ureter. TUUC is recommended in cases with at least one dilated ureter.
