ABSTRACT
Objective To observe and assess the effect about bundles of cure Rule of three three in the treatment for residual stones after Flexible Ureteroscope.Methods 120 patients with a single stone after urinary lithotripsy were divided into two groups according to the different indwelling time.Two cases of the control group were rejected because of severe hematuria.The control group (n=58) was subjected to the regular education (drinking water 3 000 ml per day with moderate exercise);The experiment group (n=60) was subjected to the Rule of three three (drinking 3 cups of water in thc morning、midday and night,with contralateral position 30 minutes,hot towel applying and gently tapping the kidney region 30 minutes).Results The calculi discharge rate and the net rate of experiment group [86.67％ (52/60),55.00％ (33/60)] were higher than the control group [53.45％(32/58),18.97％(11/58)] 14 days after surgery.The difference was statistically significant (P ＜ 0.01).Further analysis showed that the discharge rate of residual stones in lower renal calyx in experiment group [86.67％(26/30)] was higher than the control group [32.14％(9/28)].The difference was statistically significant (P ＜ 0.01).Conclusions The bundles of cure called rule of three three can improve the discharge rate of residual calculi after flexible ureteroscope and increase the discharge rate of residual stones in lower renal calyx significantly.
