ABSTRACT

In recent years, with the rapid development of rigid ureteroscopy and flexible ureteroscope lithotripsy in the field of urology, great changes have been made in the treatment of urinary calculi. Although flexible ureteroscope lithotripsy is easy to be damaged and expensive to maintain, it has high technical requirements for doctors, but it does not need to establish other traumatic channels, but uses the natural cavity of human urinary system, It has been paid more and more attention by urologists and has a good development prospect. Stone free rate is an objective index to judge the efficiency of flexible ureteroscope lithotripsy. The stone free rate and treatment after flexible ureteroscope lithotripsy have always been a difficult problem. Many scholars at home and abroad have studied the influencing factors of stone free rate after flexible ureteroscope lithotripsy, studies have shown that large stone load, hard stone composition, narrow angle of renal pelvis and calyceal and severe hydronephrosis are the main risk factors leading to the reduction of postoperative one-time stone free rate. In this paper, the research results in this field at home and abroad will be summarized.
