Objective To analyze the early renal function of donors after nephrectomy.Methods Clinical data of 467 cases of living kidney donors during the period from April,2010 and November,2014 in our center were retrospectively analyzed.Data on serum creatinine (Scr),glomerular filtration rate (GFR),serum uric acid (UA),and urine microproteins before operation and three days,seven days,one month and three months after operation were collected to evaluate the impact of nephrectomy on early renal function after operation for donators.Results Before operation and three days,seven days,one month,three months after operation,the average serum creatinine (Scr) level was (59.9±12.8),(85.8±21.0),(91.2±21.3),(92.8±21.6),(91.0±21.3) μmol/L,respectively; The GFR were (113.5±25.3),(75.1± 17.9),(70.3± 15.2),(68.5± 16.0),(69.5± 15.1) ml/min,respectively; The levels of uric acid were (292.60±79.58),(142.18±55.28),(228.41±66.39),(321.31± 83.72),(346.61±87.21) μmol/L,respectively; All these data above-mentioned after operation reached statistical significance compared with that before operation (P ＜ 0.05).Parameters including urine IgG,urine albumin,urine retinol-binding protein and urine β2-microglobulin post-operation time point were significantly different when compared with relative parameters pre-operation (P ＜ 0.05).Conclusions Nephrectomy has significant influence on GFR,uric acid,and urine microprotein for donors in the early stage after operation.It's worth to evaluate nephrectomy's long-term effect on the renal function of donors in clinical practice.

Objective:To explore the clinical risk factors of post-transplantation diabetes mellitus (PTDM) and establish a risk prediction model in kidney recipients.Methods:The clinical data and postoperative bedside measurements of blood glucose (BG) were retrospectively reviewed for 305 renal transplant recipients at First Affiliated Hospital of Zhejiang University School of Medicine from October 2018 to August 2019.According to whether or not PTDM occurred, they were assigned into two groups of PTDM (n=34) and non-PTDM (n=271). Risk factors were screened through single/multi-factor Logistic regression and PTDM prediction model was established.Results:The incidence rate of PTDM was 11.15%(34/305). Logistic regression analysis indicated that deceased donor, age ≥40 years, female, pre-hemoglobin A1c (Pre-HbA1c) and postoperative bedside BG value ≥11.1 mmol/L were the correlated factors for the occurrence of PTDM.Among them, female ( OR=3.13, 95% CI: 1.28-7.61), Pre-HbA1c ( OR=2.05, 95% CI: 1.12-3.74) and BG ≥11.1 mmol/L at 4pm Day 2/3 post-operation ( OR=19.08, 95% CI: 4.34-83.87) were risk factors for the occurrence of PTDM, The area under the model curve was 0.86 (95% CI: 0.79-0.93) with a Jordan index of 0.65, a sensitivity of 82.8% and a specificity of 82.3%. Conclusions:Female, Pre-HbA1c and fasting BG at 4 pm Day 2/3 post-operation ≥ 11.1 mmol/L are risk factors for the occurrence of PTDM.The prediction model has a decent predictive value.It is conducive to early clinical interventions and lowering the incidence rate of PTDM.
