Evaluation of the Effects of Recipient/Donor Gender on Early/Late Postoperative Renal Graft Functions by Renal Scintigraphy

Abstract

Objectives: We discuss the effects of recipient/donor gender on renal allograft functions using scintigraphic parameters obtained 3 days after renal transplant and 1 year after transplant. Materials and Methods: This retrospective study included 76 renal allograft recipients (group one, 38 males; group two, 38 females).

Patients underwent scintigraphic imaging with Tc- 99m DTPA on postoperative day 3 and 1 year after transplant. We used the Hilson perfusion index, maximum renal activity/background activity, ratio of renal activity at 20 minutes to renal activity at 3 minutes, time- to- peak activity, and glomerular filtration rate to measure quantitative parameters.

Results: On postoperative day 3, the Hilson perfusion index, maximum renal activity/background activity, the ratio of renal activity at 20 minutes to renal activity at 3 minutes, time- to- peak activity, and glomerular filtration rate values for male/female recipients were similar (P = .65, P = .77, P = .38, P = .10, P = .99). The gender of donors was compared with the above- mentioned scintigraphic parameters of the recipients, and no statistically significant differences were found (P = .24, P = .25, P = .44, P = .29, P = .13). At 1- year follow- up, values obtained from group 1 and group 2 recipients were similar. After 1 year, chronic rejection developed in 15.7% of group 1 recipients and in 10.5% of group 2 recipients; acute rejection developed in 21% of group 1 recipients and in 23.6% of group 2 recipients. There were no statistically significant differences between the occurrence of acute rejection and the gender of recipients or donors (P = 1.00, P = .45).

Conclusions: We observed no statistically significant differences between renal graft functions and gender of the recipients/donors during the early/late posttransplant period.
