[Urologic complications following vascular prosthetic interventions in the aortofemoral area]. / Urologische Komplikationen nach gefässprothetischen Eingriffen im aorto-femoralen Bereich.

ABSTRACT

After vascular graft surgery within the pelvic area, urological complications occur in about ten percent of the patients. Overlooking 310 cases, four patients suffered from ureteral lesions and 21 patients had ureteral obstructions. Possible causes for ureteral obstructions are positioning of the ureter between vessel and prosthesis, hematoma, lymphoma, anastomotic aneurysm, prosthesis infection, Morbus Ormond as well as trophical lesions of the ureter wall. Use of ureteral splint could prevent surgical intervention in many cases. Application of prophylactic pre-operative splinting is recommended in case of large aneurysm, previously injured kidney and single kidney.
