Objective The present study was designed to investigate the risk factors affecting bleeding during percutaneous nephrolithotomy. Methods The records of 218 patients with percutaneous nephrolithotomy procedure by a single surgeon were retrospectively reviewed.The mean age was 48 years ( range,19 -70).One hundred and forty six patients had staghore stones,and 7 patients had previous open or percutaneous nephrolithotomy histories.Forty-one patients had concomitant diabetes mellitus,and 89 cases had hypertension.The following factors including age,sex,BMI,diabetes status,hypertension status,stone type,calix of puncture,previous open or percutaneous nephrolithotomy history,number of accesses,size of accesses,operative time,and surgeon experience were analyzed.Univariate analysis and multivariate step regression analysis were used for statistical assessment. Results 207 procedures were successfully performed,and 11 patients failed because of difficulty to establish the accesses.Single-tract was used in 176 cases and multiple-tract was used in 31 cases.163 cases were performed via a 18 F access and 44 cases via a 24 F access.The mean operative time was 78.4 min.The overall blood transfusion rate was 7.7%,and stone type ( P =0.034),diabetes ( P =0.030),number of accesses ( P =0.019 ),size of accesses ( P =0.008) and operative time (P =0.001 ) were the risk factors affecting blood transfusion requirement.The average hemoglobin (Hb) drop after percutaneous nephrolithotomy procedures was 11.2 g/L,and stone type ( P < 0.001 ),diabetes ( P =0.015 ),number of accesses ( P =0.016),size of accesses ( P < 0.001 ) and operative time ( P < 0.001 ) were the risk factors affecting Hb drop.The following covariates including Hb drop:age,sex,BMI,previous open or percutaneous nephrolithotomy history,hypertension status,calix of puncture and surgeon experience were not risk factors affecting blood transfusion requirement and Hb drop.Multivariate stepwise regression analysis showed that diabetes ( OR =1.75 ),stone type ( OR =1.92),number of accesses ( OR =2.45 ),size of accesses ( OR =1.32) and operative time ( OR =1.66) significantly increased risk of bleeding. Conclusions Stone type,diabetes,number of accesses,size of accesses and operative time were the risk factors affecting blood loss during percutaneous nephrolithotomy.

Objective:To evaluate the perioperative safety of pancreaticoduodenectomy(PD)in elderly patients.Methods:Clinical data of 152 patients undergoing PD in Beijing Hospital between 2016 and 2019 were retrospectively analyzed.According to the age, patients were divided into the elderly group(age≥65 years)and the non-elderly group(age<65 years). The perioperative and postoperative parameters were compared between the two groups.Results:There was no significant difference in the operative time, intraoperative blood loss and intraoperative urine output between the elderly group and the non-elderly group(352.7±69.5)min vs.(359.0±94.4)min, (708.7±672.7) vs.(662.6±896.7)ml and(875.8±497.3)ml vs.(1010.6±568.2)ml, all P>0.05). The perioperative mortality, postoperative complications(Clavien-Dindo classification ≥ grade Ⅲ)and reoperation rate had no significant difference between elderly group and the non-elderly group(6.1% vs.1.2%, 21.2% vs.19.8%, 10.6% vs.8.1%, respectively, χ2=1.487, 0.048 and 0.272, all P>0.05). The incidences of operation-related complications, cardiovascular or cerebrovascular adverse events in elderly group were comparable to non-elderly group( P>0.05). The postoperative hospital stay had no significant difference between the elderly group and the non-elderly group[(28±19)d vs.(27±18)d, P>0.05]. Conclusions:PD is safe in elderly patients.Age is not a contraindication to pancreaticoduodenectomy.The comprehensive systemic evaluation, intraoperative delicate operation and enhanced perioperative management are necessary in the elderly patients undergoing PD.
