Experience with autosomal dominant polycystic kidney disease in patients before and after renal transplantation: a 7-year observation

Transplant Proc. Jan-Feb 2009;41(1):177-80. doi: 10.1016/j.transproceed.2008.10.034.

Abstract

Objective: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the presence of multiple cysts in both kidneys. Symptoms of the disease may arise either from the presence of cysts or from increasing loss of kidney function. First symptoms usually appear in the third decade of life: lumbar pain, urinary tract infections, arterial hypertension, or renal colic due to cyst rupture or coexistent nephrolithiasis. An early diagnosis, male gender, large kidneys by sonography, arterial hypertension, hematuria, and urinary tract infections are predictive factors of a faster progression of the disease. Our aim was to establish the indications for nephrectomy among symptomatic ADPKD patients before kidney transplantation and to assess the risks of posttransplantation complications among ADPKD patients without nephrectomy.

Patients and methods: The observed group consisted of 183 patients with ADPKD among whom 50 (27.3%) underwent kidney transplantation during a 7-year observation period (2000-2007). Among those subjects were 3 groups: (I) nephrectomy preceding transplantation; (II) nephrectomy during kidney transplantation; and (III) without nephrectomy.

Results: Among group I before transplantation we observed: arterial hemorrhage, wound infections, and splenectomy 4 weeks after ADPKD nephrectomy; afterward we observed: urinary tract infections and contralateral cyst infection. Among group II we only observed 1 case of wound infection. Among group III we observed: ascending urinary tract infections, cyst infections, and cyst hemorrhage. Cyst hemorrhage and cyst infections led mainly to ADPKD kidney nephrectomy. During the observation time, 80.95% of grafts were functioning.

Conclusions: Unilateral nephrectomy is a well-founded preliminary surgical treatment before kidney transplantation. Bilateral nephrectomy before or during transplantation eliminates ADPKD complications and does not significantly increase general complications. The greatest numbers of complications and of graft losses were observed among the group without pretransplantation nephrectomy.
