Kidney transplantation is indicated for end-stage renal disease. Autosomal dominant polycystic kidney disease (ADPKD) causes structural degeneration of the kidney and eventually becomes end-stage renal disease. ADPKD patients usually have several renal and nonrenal complications. We analyzed our kidney transplantation activities between 1991 and 2010 regarding ADPKD. We followed up with patients to December 31, 2016. Data were collected as patient and graft survival rates, the prevalence of polycystic manifestation of the gastrointestinal tract and other organs, and the attendance of urinary tract infection. Among the 734 kidney transplantations, 10.9% (n = 80) had an ADPKD. Four patients (5%) had diverticulum perforation. The prevalence of post-transplantation urinary tract infection was higher in ADPKD patients (55.9%) compared to non-ADPKD patients (44.1%). The 1-, 3-, and 5-year overall survival rates in ADPKD recipients versus non-ADPKD patients are 77.5%, 70.0%, and 67.5% versus 86.4%, 83.0%, and 80.1%, respectively. Patients with ADPKD were transplanted at an elder age compared to others (median: 47.5 years vs. 39.9 years). Female patients had longer graft survival times than males. ADPKD implies multiple cystic degeneration of the kidneys; however, it can cause structural degeneration in other organs. It is typical for ADPKD patients to have an acute abdominal-like syndrome. Immunosuppressive drugs can hide the clinical picture, which makes early diagnosis difficult.
