ABSTRACT
Objective To explore treatment methods of donor kidney with single calculus in living renal transplantation and their effect.Methods The treatment experience of donor kidneys with unilateral renal calculus in living renal transplantation of 3 cases was summarized,which were diagnosed before operation.The kidney with renal calculus was excised as the donor kidney;ureteroscopic lithotomy was conducted in vitro,and then renal transplantation was performed by routine operation.Results There was no early complication such as delayed graft function and acute rejection in 3 recipients after operation.Three pairs of donors and recipients were followed up for 34,45 and 62 months respectively.The color Doppler ultrasound examination of urinary system after renal transplantation showed that,new renal calculus and urinary tract obstruction did not occur in donor's preserved kidneys and recipient's transplant kidneys.Renal function of all donors and recipients was good.Three donors were followed up until now,and no abnormal urine routine was discovered.One recipient developed IgA nephropathy,which was considered to be recurrent nephropathy and had nothing to do with renal calculus.Conclusions The donor kidney with single calculus in living renal transplantation can be treated effectively by ureteroscopic lithotomy in vitro after donor kidneys are excised.
ABSTRACT
Objective To summarize the experience of retroperitoneal laparoscopic living donor nephrectomy.Methods Clinical data of 22 donors undergoing retroperitoneal laparoscopic living donor nephrectomy in the First Affiliated Hospital of Sun Yat-sen University from January 201 2 to May 201 4 were analyzed retrospectively.The ureter,renal vessel and perirenal fat were dissected by laparoscopic approach.Then the renal vessels were cut off and the kidney was extracted by hand through superomedial inguinal parallel incision.The surgical process and the postoperative follow-up of the donors were recorded.Results One right kidney and 21 left kidneys were extracted.The operations in 22 cases were performed successfully without conversion to laparotomy.The operation time was (1 23 ±31 )min.The length of kidney extracting incision was (7.2 ±0.5)cm.The intraoperative blood loss was 1 5-80 ml and the warm ischemia time was 60-1 50 s.The length of donor renal arteries was 2.0-3.2 cm.The length of renal veins was 1 .0-3.5 cm.The donors were followed up for 1 -21 months.The serum creatinine (Scr)levels at 1 d,1 week and 1 month after operation were (1 20 ±57),(95 ±25),(90 ±21 )μmol/L respectively.Two cases suffered from renal fossa hematoma and poor wound healing after operation respectively.The pain score of the donors was 0-5 at 1 week after operation and 0-1 at 1 month after operation.No donor had the perception that donating kidney had obvious impacts on the general health,but 1 donor felt it had some influence on physical strength.Conclusions It is safe to perform retroperitoneal laparoscopic living donor nephrectomy on the basis of strict donor selection.It has little impacts on the donor's quality of life with small surgical incision and mild postoperative pain.
