ABSTRACT
Objective To compare the efficacy of three endoscopic surgery in impacted upper ureteral calculi treatment.Methods 218 patients with impacted upper ureteral calculi were treated with minimally invasive percutaneous nephrolithotomy (MPCNL),transurethral ureteroscope lithotripsy(URL)and retroperitoneal laparoscopic urerolithotomy (RLU)respectively.The operation safety,efficacy and complication were compared in the three groups.Results In the MPCNL group,URL group,RLU group one success rate of lithotripsy were 100.00%,85.19%,100.00% respec-tively.The mean operative time were (76.35 ±16.20)min,(46.26 ±15.30)min,(89.20 ±19.60)min respectively. Decreased hemoglobin values were (22.24 ±8.63)g/L,(4.15 ±1.89)g/L,(10.68 ±4.55)g/L respectively.The stone -free rates of one month postoperation were 96.32%,79.59%,100.00%.Length of hospital stay were (8.56 ± 2.13)d,(6.58 ±1.76)d,(9.79 ±2.14)d,respectively,the differences were statistically significant(t/χ2 =36.916, 27.629,all P <0.05).Conclusion MPCNL and URL for impacted upper ureteral calculi is safety and has good efficacy and less complications,but the MPCNL is recommended the first choice,some cases can try URL.
