Background: Increasing the living-donor pool by accepting donors with an isolated medical abnormality (IMA) can significantly decrease the huge gap between limited supply and rising demand for organs. There is a wide range of variation among different centres in dealing with these categories of donors. We reviewed studies discussing living kidney donors with IMA, including greater age, obesity, hypertension, microscopic haematuria and nephrolithiasis, to highlight the effect of these abnormalities on both donor and recipient sides from medical and surgical perspectives. Methods: We systematically searched MEDLINE, ISI Science Citation Index expanded, and Google scholar, from the inception of each source to January 2011, using the terms ?kidney transplant?, ?renal?, ?graft?, ?living donor?, ?old?, ?obesity?, ?nephrolithiasis?, ?haematuria? and ?hypertension?. In all, 58 studies were found to be relevant and were reviewed comprehensively. Results: Most of the reviewed studies confirmed the safety of using elderly, moderately obese and well-controlled hypertensive donors. Also, under specific circumstances, donors with nephrolithiasis can be accepted. However, persistent microscopic haematuria should be considered seriously and renal biopsy is indicated to exclude underlying renal disease. Conclusion: Extensive examination and cautious selection with tailored immunosuppressive protocols for these groups can provide a satisfactory short- and medium-term outcome. Highly motivated elderly, obese, controlled hypertensive and the donor with a unilateral small stone (<1.5 cm, with normal metabolic evaluation) could be accepted. Donors with dysmorphic and persistent haematuria should not be accepted. A close follow-up after donation is crucial, especially for obese donors who developed microalbuminuria.
