Diverticulitis and polycystic kidney disease.
Patients with adult polycystic kidney disease (PKD) have previously been shown to have an increased incidence of complicated diverticulitis after renal transplantation. The purpose of this study was to assess the risk of diverticulitis in the PKD population. We retrospectively reviewed patients with advanced PKD, defined as end-stage renal failure requiring dialysis. Patients were obtained from a single nephrology group practice between January 1985 and January 1997, or from all patients being evaluated or actively considered for renal transplantation at our institution as of May 1997. The incidence and severity of diverticulitis in these patients was compared with that observed in a similar cohort of patients with end-stage renal disease due to other etiologies. The study population consisted of 184 renal failure patients, 59 with PKD and 125 with other causes of end-stage renal disease. Twelve (20%) patients with PKD had a history of active diverticulitis, whereas only 4 (3%) of the non-PKD controls had diverticulitis (P = 0.0003, Fisher's exact test). Six of the 12 PKD patients required surgical intervention. Patients with renal failure due to PKD experience a significantly higher rate of diverticulitis than do other patients with end-stage renal disease. Furthermore, diverticulitis is frequently severe in PKD patients, with 50 per cent requiring surgical intervention. These data suggest that diverticular disease may be an extrarenal manifestation of polycystic kidney disease.
