Increased incidence of gastrointestinal surgical complications in renal transplant recipients with polycystic kidney disease.

We had the impression that, although our renal transplant recipients with polycystic kidney disease (PKD) had excellent long-term renal graft function, they had an increased incidence of postoperative gastrointestinal (GI) complications.


Over a 10-year period (1987 through 1996), 1467 renal transplants were performed in 1417 patients; 145 of these transplants involved PKD recipients. In the PKD group, 18 patients (12.4%) developed a posttransplant complication necessitating GI surgery (PKD-GI), an incidence twice that in the non-PKD recipients (73 patients or 6.2%, non-PKD-GI).


PKD and non-PKD recipients displayed no significant difference in mortality. The PKD patients had better long-term renal graft survival than the non-PKD patients (P=0.08). There was no difference in mortality (P>0.6) or renal graft survival (P>0.6) between the PKD-GI and PKD-non-GI groups. The PKD-GI group had no increased mortality over the non-PKD-GI patients (P>0.6), despite a higher incidence of GI surgical complications in the PKD group versus the non-PKD group (overall: 12.4 vs. 6.2%, P<0.01; within 90 days of transplant: 7.6 vs. 3.3%, P<0.02) and a greater propensity for small and large bowel complications (overall: 9.0 vs. 2.6%; P< 0.001; less than 90 days: 6.9 vs. 2.0%, P<0.002). The PKD-GI recipients tended toward less long-term graft loss than their non-PKD-GI counterparts (11.1 vs. 27.4%; P=.22). The PKD-GI recipients suffered no acute rejection episodes within 90 days after their GI operation versus 11 of 73 non-PKD-GI recipients (O vs. 15.1%; P=0.075).


PKD recipients of renal grafts should be watched closely early after transplant because of their increased risk of GI complications. These complications resulted in no increase in mortality or graft loss compared to non-PKD recipients with GI complications despite the PKD group's higher incidence of bowel perforation and increased age at time of transplant.
