BackgroundTo analyze the association between the principal immunosuppressive drugs (mycophenolate mofetil, calcineurin inhibitors and mammalian target of rapamycin [mTOR] inhibitors) used in the routine management of kidney transplant patients and the development of postoperative surgical complications. Materials and MethodsWe analyzed 415 kidney transplants, studying the influence of various immunosuppressive regimens on the main postoperative surgical complications. ResultsThe mean follow-up for the entire group was 72.8 months (± 54.2 SD). Patients treated with myeophonolate mofetil (MMF) and cyclosporine (n = 121) experienced a higher frequency of wound eventration odds ratio [OR], 5.2; 95% confidence interval [CI], 1.2–23.5; P = .03) compared with azathioprine and cyclosporine (n = 71). Compared with transplant recipients treated with tacrolimus and MMF (n = 181), transplant recipients treated with cyclosporine and MMF (n = 121) had a significantly greater frequency of wound eventration (OR, 3.7; 95% CI, 1.5–9.5; P = .005), urologic (OR, 2; 95% CI; 1.02–3.9; P = .04), wound (OR; 2.2; 95% CI; 1.07–4.6; P = .03), late (OR, 1.7; 95% CI; 1.01–3.03; P = .04), and Clavien grade 3 surgical complications (OR; 1.9; 95% CI, 1.1–3.37; P = .01). Patients treated with mTOR inhibitors (n = 26) had higher rates of lymphocele (OR, 3.6; 95% CI, (1.1–11.4; P = .002) compared with those who received tacrolimus (n = 197). ConclusionsNew immunosuppressive drugs have improved short-term functional results; however, in some cases they seem to increase surgical complications rates.
