RESUMEN
Objective To explore the effect of MPCNL in the treatment of complex proximal ureteral calculi.Methods 90 cases were involved in treatment of complex proximal ureteral calculi in our hospital.MPCNL group were 45 cases and U RL group surgery were 45 cases.Results The operation time,bleeding,single surgery success rate,stone-free rate after surgery success for URL and MPCNL were(34.8 ± 10.5) minutes and ( 112.5 ± 12.4) minutes,(12.5 ± 4.6)ml and (51.3 ±3.7)ml,71.1％ and 95.6％,91.1％ and 97.8％ respectively(P ＜ 0.05).Conclusions The operntive time of URL is shorter,blood loss of URL is less than those of MPCNL,but the success rate of surgery and stone-free rate of URL is not higher than those of MPCNL.Both treatment methods are safe and reliable without serious complications.
