[Perforation of sigmoid diverticula. A complication following allogenic kidney transplantation].

In the early post-operative follow-up after allogenic kidney transplantation sigmoid perforation due to diverticula is a life-threatening complication. As immunosuppression is indispensable perforation is favoured. Due to pharmacotherapy the risk of sepsis is implied because clinical symptoms might be masked. Reference is made in this paper to four cases to describe clinical course, diagnostic and surgical approaches as well as diagnostic-therapeutic consequences for the patient of the waiting list.
