Reconstruction of long ureteral obstructions using xenogenic acellular collagen membranes.

OBJECTIVE

Extensive stricture of ureter still poses a difficult challenge for urologic surgons, especially when its middle part is affected. We present a reconstructive method of long ureteral strictures with use of xenogenic collagen membranes as a scaffolding to promote new tissue growth in the area of extensive ureter defect.

PATIENTS AND

METHODS

Between 1980 and 2002 we applied and evaluated results of the new procedure in a total of 7 females and 3 males suffering from a various degree of hydronephrosis caused by extensive ureter stricture.

RESULTS

Early and long-term follow-up excretory urography demonstrated lack of obstruction in the operated ureter segment in all cases.

CONCLUSIONS

Easy surgical procedure, no complications after surgery excellent short and long-term results prove the efficacy and usefulness of the presented therapeutic option.
