Objective To explore the influence of living donor renal transplantation on the safety of donors.Methods Sixty-two donors who underwent living donor renal transplantation in the First Affiliated Hospital of Xinjiang Medical University from April 2003 to April 2007 were selected as research objects.The operation time and length of stay of donors were recorded.The occurrence of postoperative complication and prognosis were observed.Postoperative follow up included serum creatinine (Scr),blood urea nitrogen (BUN),glomerular filtration rate (GFR),plasma albumin,hemoglobin,blood pressure and the influence of kidney donation on life and work.Results The operations of 62 donors were successful.One case developed pneumothorax during open nephrectomy and another case developed fat liquefaction and necrosis of incision.Both of them were cured after symptomatic treatment.Two cases developed pulmonary infection postoperation and were cured after the treatment of sensitive antibiotics and aerosol inhalation.The other cases recovered smoothly after operation.In 62 donors,the average postoperative length of stay was (8.2 ±2.6)d,and the follow-up time was (3.2 ±1 .1 )years.All of the donors survived without influence on life and work.No significant difference was observed in the changes of Scr,BUN,GFR,plasma albumin,hemoglobin,blood pressure of the donors before operation and 7 d,3 months,1 year,3 years,5 years after operation (all in P >0.05).Conclusions The living donor nephrectomy is safe and feasible.It is very important for assuring the safety of donors to examine living donor perfectly before operation,be careful during operation,and closely follow up after operation.

Objective To explore the application effect of prone split-leg position in percutaneous nephrolithotomy(PCNL).Methods A total of 79 patients with upper urinary tract stones who underwent surgery in our department from July 2021 to July 2022 were selected.According to the surgical position,the patients were divided into prone split-leg position group(n =35)and traditional prone position group(n =44).The two groups were compared regarding operation time,intraoperative blood loss,postoperative and preoperative hemoglobin changes,postoperative complications,one-stage stone free rate,and duration of hospitalization.Results The prone split-leg position group had significantly shorter operative time and higher one-stage stone free rate than those in the traditional prone position group[(69.6±20.7)min vs.(90.5±35.3)min,t =-3.280,P =0.002;97.1%(34/35)vs.79.5%(35/44),χ2 =3.984,P =0.037].There were 1 case of infection,3 cases of fever,and 1 case of bleeding in the prone split-leg position group,while 4 cases of postoperative fever and 2 cases of bleeding in the traditional prone position group,without significant difference in the incidence of complications between the two groups(χ2 =0.000,P =1.000).There were no statistical differences in intraoperative blood loss,number of working channel,hemoglobin changes,and duration of hospitalization(P>0.05).Conclusion Prone split-leg position PCNL can shorten the operation time,improve the one-stage stone free rate,and will not increase the risk of postoperative complications,with good safety and effectiveness.
