Objective To explore the curative effect of combined use of minimally invasive percutaneous nephrolithotomy (MPCNL) and extracorporeal shockwave lithotripsy (ESWL) for the treatment of solitary renal staghorn calculi in patients with renal insufficiency. Methods Eight cases of solitary renal staghorn calculi associated with renal insufficiency were treated by a combination of MPCNL and ESWL. Results Stones were completely cleared away in 5 cases, while residual stones were found in 3 cases. No blood transfusion was required and no severe surgery-related complications were encountered. After surgery variable degrees of improvement in renal functions was observed. The serum creatinine (Cr) decreased from 289?166 ?mol/L pre-operation to 155?33 ?mol/L post-operation (t=4.69, P=0.004), and the blood urea nitrogen (BUN) decreased from 15.1?7.9 mmol/L to 8.3?1.9 mmol/L (t=4.00, P=0.005). The emission computed tomography (ECT) examinations showed the glomerular filtration rate (GFR) was elevated from 48.8?12.4 ml/s before operation to 63.0?8.4 ml/s after operation (t=4.68, P=0.003). Post-renal obstruction disappeared after operation. Follow-up for 0.5~4.5 years (mean, 2.8 years) in the 8 cases revealed no obvious changes in renal functions. Conclusions Combination of MPCNL and ESWL for solitary renal staghorn calculi associated with renal insufficiency is safe and effective.

Objective To evaluate the impact of donor age on graft short-term outcome after right lobe adult living donor liver transplantation (LDLT).Method Thirty living recipients were divided into 2 groups according to donor age:older donor group (O group,donor age ＞50,n =5) and younger donor group (Y group,donor age ＜30,n =25).Alanine transarninase (ALT),aspartate transaminase (AST),total bilirubin (TB),prothrombin time (PT) on the postoperative day 1 to 5 and graft liver regenerative ratio (LRR) on the postoperative month 0.5,1,3,and 6 between 2 groups were determined and compared.Result TB on postoperative day 1,2,3,4 and 5 was significantly higher in O group than in Y group there were significant differences between two groups (P＜0.01).There was no significant difference of other liver function parameters 2 groups (P ＞ 0.05).There was no significant difference in LRRs on the postoperative month 0.5,1,3 and 6 months postoperatively between 2 groups after LDLT (P＞0.05).Conclusion Although allografts from older donors in LDLT have prolonged jaundice than those of their younger counterparts,after strictly preoperative evaluation,donor age has little effect on short-term outcomes of graft after LDLT.

Objective To evaluate the impact of donor age on early remnant liver function and regeneration after right lobe adult living donor liver transplantation (LDLT) donation.Methods 43 living donors were divided into 2 groups:donor age ＞ 50,n =8,and donor age ＜ 30,n =35.Alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TB) and liver regenerative ratio (LRR) of donors between the 2 groups were compared.Results There were no significantly different in ALT,AST and TB on days 1,2,3,5 after LDLT between the 2 groups (respectively t =0.147,1.030,-0.903,0.013,0.043,1.362,0.817,0.003,1.121,0.241,1.061 and 0.943,all P＞0.05).There was significant difference between LRR on day 7 (t =-0.965,P =0.042),but the difference was not statistically significant in LRR when evaluated on day 15 after LDLT (t =0.585,P =0.385).Conclusions Remnant liver regeneration on the first week is reversely affected by donor's age after hepatectomy,while the influence of age decreases significantly after 2 weeks.

Objective To evaluate and compare liver regeneration between normal donors and recipients at the different stages after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-eight living donors and 63 recipients without complications were included in this study.We did CT volumetric measurement of the liver by using IQQA-Liver workstation.The relationship between graft volume measured by preoperative MSCT and intraoperative actual graft volume was evaluated.The liver regenerative ratio at different stages of donors and recipients after LDLT was calculated and compared.Result Preoperative measurement of total liver and grafts resulted in a mean volume of (1366.99 ± 234.75) cm3 (standard deviation) and (862.73 175.94) cm3 (VCT-right),respectively.Intraoperative volume of the grafts was (654.46 ± 151.23) ml (Vintraop).Corresponding pre-and intraoperative data were correlated significantly each other (r =0.795,P=0.000).Vintraop can be calculated with the equation:Vintraop =64.949 + 0.683 VCT-right.There was significantly difference in LRR between donors and recipients at 0.5,1,3 and 6 months after LDLT (P＜ 0.05).Conclusion The patterns of normal liver regeneration between donors and recipients after LDLT are different.The liver of donors regenerates more significantly and quickly than recipients.Liver volumetric measurement by using MSCT is a valid modality to evaluate liver regeneration after LDLT.

Objective To evaluate graft regeneration and influencing factors after right lobe adult living donor liver transplantation (LDLT) using MSCT.Method Sixty-three living recipients were included in this study.We measured graft volume periodically by using MSCT and IQQA-Liver workstation.The liver regenerative ratio (LRR) of different stages of recipients after LDLT was calculated and compared,and stepwise regression analysis was done to set up the regression equation.Result Within 0.5 month after LDLT,graft volume was increased rapidly,and LRR reached maximum [(106.11 + 30.90)％],then decreased slowly.There was significant difference in LRR among 0.5,1 month and 3,6 months after LDLT (P＜0.05).The following factors,including whether the graft containing middle hepatic vein or not,age and sex of recipients,had no significant influence on LRR after LDLT (P＞0.05).The status of liver function of recipients preoperatively had significant influence on LRR 0.5 month after LDLT (P＜0.05).There was significantly negative correlation between the graft volume and LRRs of recipients at different stages after LDLT (P ＜ 0.05).Regression equation could be derived.Conclusion Most evident graft regeneration occurs in early stage after adult LDLT.There are many and different factors influencing graft regeneration at the different stages after LDLT.Graft volumetric measurement by using MSCT is a valid modality to evaluate graft regeneration after LDLT.
