ABSTRACT

Objective To study the safety and feasibility of tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel.Methods Eighty patients after conventional percutaneous nephrostolithotomy are selected and divided into two groups according to the principle of randomization.Control group adopts conventional percutaneous nephrostolithotomy calculi lithotripsy with renal pelvis drainage tube placement whereas the experimental group adopts tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal channel.Both experimental group and control group will be scientifically and statistically analyzed via the incidence and the dose of using sedative for alleviating pain after operation,hospital stay,level of hemoglobin,and the occurrence of complications such as continuate hemorrhage,infection,urinary extravasation,etc.Results The operation of both groups are successful in phrase Ⅰ.The incidence and the dose of using sedative in control group are obviously higher than that in experimental group(45％ vs 20％).However,the incidence of postoperative complications like infection and hemorrhage and hospital stay between two groups are undifferentiated in statistics(P ＞ 0.05).Neither the experimental group nor the control group has perinephric hematoma,and seven cases of control group have urinary leakage after remove of fistula.Conclusion Tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel is safe and feasible and it can reduce the incidence of postoperative pain and avoid urinary leakage.
