ABSTRACT

【Objective】 To investigate the safety and efficacy of flexible ureteroscope (FU) combined with retrograde ureteroscope (URS) in the treatment of lower ureteral calculi with ureteral atresia. 【Methods】 Clinical data of 7 patients treated during Jan.2018 and Jun.2021 were retrospectively analyzed. 【Results】 Ureteral calculi and ureteral atresia were successfully treated, without serious complications. Six to eight weeks after operation, CT examination showed that hydronephrosis was relieved to varying degrees and the ureteral stents were in good position, without residual stones. Six months after operation, there was no significant exacerbation of hydronephrosis and the renal function remained stable. 【Conclusion】 Anterograde FU combined with retrograde URS has high stone-clearance rate, small trauma and high safety in the treatment of ureteral stricture and ureteral calculi.
