Contrastive Study On Negative Pressure Combined With Ureteroacopy And Flexible Ureteroscopy Lithotripsy In The Treatment Of Less Than 2 Cm Kidney Stones

Objective:To compare the clinical effect of negative pressure combined with ureteroacopy(NPCU)and flexible ureteroscopy lithotripsy(FURL)in the treatment of kidney stones,and to discuss the efficiency and safety of the two kinds of surgical procedures for treating kidney stones(stone diameter:<2cm).Method:This study selected January 2017 to January 2018 in the Department of China-Japan Union Hospital of Jilin University Urology confirmed a diagnosis: 72 cases of kidney stones were retrospectively analyzed,All patients in the group were diagnosed as unilateral single or multiple kidney stones(stone diameter:<2cm)by assistant examination such as urinary ultrasound,Abdominal KUB,Intravenous Pyelography and CT and CTU of urinary system.In the patients with renal pelvis,renal upper calices,renal middle calices,no related contraindications,and history of ureteral surgery,urological anatomy and other anomalies associated with the results of analysis and those who have renal tuberculosis or kidney cancer.Among them,including the negative pressure combined with ureteroacopy(NPCU group)for patients with kidney stones 34 Cases,flexible ureteroscopy lithotripsy(FURL group)treatment of kidney stones in 38 patients.Retrospective analysis of gender,age,BMI,diameter of stone,stone position,stone distribution Ureteral Acess Sheath(UAS),operation time,postoperative complications,the stone-free rates in postoperative 1 day and 1 month,average hospitalization time;Research results:1?In all cases,the whole patients were successfully finished and without serious ureteral injury(piercing.,breaking stripping),without severe renal hemorrhage,without septic shock.2?There was no statistical difference between the two groups in age,sex,BMI,calculus diameter,stone position and stone distribution(P> 0.05).3 ? The stone-free rates of NPCU group and FURL group of postoperative 1 month were 32/34(94.11%)and 35/38(92.10%)respectively;The postoperative complications were 2/34(5.88%)and 4/38 10.52%)respectively;The operative time were(39.15±10.20)min,and(38.94±11.22)min respectively;Average hospitalization time.were(4.05 ± 1.69)days and(4.18 ± 1.65)days respectively;There was no statistical difference between the two groups(P> 0.05).4?Success rate of placement Ureteral Acess Sheath in NPCU group and FURL group were 32/34(94.11%)and 28/38(73.68%),and the stone-free rates of postoperative 1 day were 29/34(85.29%)and 23/38(60.52%).There were statistically difference(P <0.05).Conclusion:Negative pressure combined ureteroscope(Shuotong ureteroacopy)is a safe and effective treatment for <2cm of kidney stones,which is an improved method for treating kidney stones through natural channels of the human body.
