Clinical observation of hand-assisted laparoscopic live donor nephrectomy / 中南大学学报(医学版)

OBJECTIVE@#To investigate the feasibility and advantage of hand-assisted laparoscopic live donor nephrectomy in renal transplantation.@*METHODS@#Six living relative donors received retroperitoneal left-side laparoscopic nephrectomy. The operating time of nephrectomy, the warm ischemic time, the recovery time of allograft and donors were recorded and analyzed.@*RESULTS@#The mean operating time of nephrectomy was 150 minutes, the mean warm ischemic time was 3.5 minutes, and the mean time of micturition after graft reperfusion was 82 seconds. The donors recovered rapidly and returned to normal within 30 days . The urine volume and renal function of the 6 recipients were normal without complications in the following 3 months.@*CONCLUSION@#Hand-assisted laparoscopic live donor nephrectomy is feasible with short operating time and warm ischemic time; the donors experience less pain, and recover rapidly. This technique may be widely used in living donor nephrectomy.

Treatment of renal calculi with percutaneous nephrolithotomy / 中华泌尿外科杂志

Objective To evaluate the feasibility and efficacy of percutaneous nephrolithotomy (PCNL)in treating renal calculi.Methods The data of 118 patients with renal calculi who had underg- one PCNL from July 2002 to August 2004 were retrospectively analyzed.There were 86 men and 32 women. The mean age was 39 years(range,7-68 years).Of the 118 cases,11 had pelvic calculi,16 had calyx cal- culi,35 had pelvocalyceal calculi,54 had staghorn calculi,and 2 had bilateral renal calculi.The mean stone size was 2.5 cm?1.5cm(ranged from 2.0 cm?1.0 cm to 4.5cm?4.0cm).Results Of the 118 ca- ses,112 underwent one-stage PCNL,and 6,two-stage PCNL.The procedure was performed by single tract in 114 cases,and by two tracts in 4 cases.Lithotomy was done by one session in 60 cases,by 2 sessions in 42 cases,and by 3 sessions in 16 cases.The total stone clearance rate was 81.4%.The mean operative time was 120 min,and mean hospital stay was 15 d.No blood transfusion was needed during operation,and only one patient experienced bleeding(about 500 ml)after 4 d postoperatively,and was cured by conservative treat- ment such as blood transfusion and anti-inflammation.No major complications were observed in other pa- tients.Conclusions PCNL has advantages of minimal trauma,less blood loss,fewer complications,and is safe and effective in treating renal calculi,especially for patients who will have the second procedure.
