One hundred consecutive kidney transplantations with simultaneous ipsilateral nephrectomy in patients with autosomal dominant polycystic kidney disease.

PURPOSE: Surgical management of autosomal dominant polycystic kidney disease (ADPKD) in patients awaiting renal transplantation is a challenging task.

METHODS

From 1998 to 2009, a total of 100 consecutive renal transplantations with simultaneous unilateral nephrectomy were performed in 59 men and 41 women with ADPKD and end-stage renal failure. About 38% received kidney allografts from living donors. The ipsilateral polycystic kidney was removed at the time of renal transplantation. Immunosuppressive therapy was not modified. Cold ischaemia time was 155 (38-204 min) versus 910 min (95-2760 min) for living versus deceased donor transplantation. Mean weight of removed kidneys was 2002 g (414-8850 g). Mean follow-up was 3.0 years (0.8-10.0 years).

RESULTS

Overall patient and graft survival were 97 and 96% at 1 year and 93 and 80% at 5 years, respectively. Serum creatinine at current follow-up was 1.49 (0.8-2.8) mg/dL. Surgical complications, which might be associated with simultaneous nephrectomy requiring re-operation, occurred in 12% (lymphocele 4%, hernia 4%, post-operative haematoma or bleeding 4%). None of the patients died peri-operatively.

CONCLUSION

Renal transplantation with simultaneous unilateral nephrectomy in ADPKD is a reasonable procedure for patients suffering from massively enlarged native kidneys.
