RESUMEN
Objective To summary the clinical data of pediatric renal transplantation from multiple renal transplant centers in China,and analyze the factors influencing the therapeutic outcomes of pediatric renal transplantation.Methods From March 1986 to May 2010,the clinical data of 138 children who underwent renal transplantation in eight centers of renal transplantation in China were retrospectively analyzed.Results The one-year patient and graft survival rate was 99.3％ and 95.7％respectively.Acute rejection episodes occurred in 38 cases (27.5％),15 cases suffered delayed graft function (DGF),and graft functions were returned to normal in all recipients within one month.Moreover,other complications included transplant renal artery stenosis in 8 cases (5.8％),ureteral necrosis in 2 cases (1.4％),urinary fistula in 5 cases (3.6％),hypertension in 57 cases (41.3 ％),hyperlipidemia in 38 cases (27.5％),hirsutism in 32 cases (23.2％),drug-induced liver damage in 26 cases (18.8％),urinary tract infection in 25 cases (18.1％ ),gingival hyperplasia in 22 cases (15.9％),pulmonary infection in 21 cases (15.2％),bone marrow suppression in 12 patients (8.7％),herpes simplex in 10 cases (7.2％),and diabetes in 8 cases (5.8％).The body weight was increased by 4 to 13 kg and the body height was increased by 2 to 7 cm during the first year posttransplantation. Conclusion The careful perioperative management, rational use of immunosuppressive agents,strengthening the follow-up management of children and social support,and improving compliance were the key points to obtain good outcomes in pediatric renal transplantation.

Objective To study the changes of the semen quality and the spermatogoa ultrastructure in uremic patients before and after renal transplantation. Methods The semen was analyzed and spermatogoa were investigated under scanning electron microscopy (SEM) in 8 patients before and after renal transplantation and 5 normal volunteers. Results In uremic patients, there was significant decreases in sperm motility, survival rate and sperm density. Under SEM, the deletion of the acrosome, distinct vacuoligation in the nucleus, deficiency of the postacromal and postnuclear ring and ~absence of the middle segment of mitochondrial sheath were found. After renal transplantation, the semen main parameters were significantly improved (P
RESUMEN
Objective To investigate the semen variation of the uremia patients after renal transplantation. Methods The semen samples from 10 uremia patients before (group A) and after (group B) renal transplantation and 12 normal volunteers(group C) were analyzed,and the main semen parameters of the 3 groups were compared. Results The mean sperm motilities of groups A,B and C were (13.8? 2.8 )%、(48.3?7.2)% and (63.8?3.6)%,respectively,the vitalities were (24.2?4.1)%、(76.3?3.9)% and (80.4?2.2)%,and the normal sperm morphologies were (15.6?2.3)%、(17.7?1.9)% and (33.8?3.7)%.The sperm motility and vitality of group B were significantly improved than group A(both P 0.05). Conclusions The successful renal transplantation can improve the semen parameters of the uremia patients.
