微创经皮肾取石术治疗孤立的肾盏结石

Treatment of isolated calyceal calculi with mini-percutaneous nephrolithotomy

目的探讨微创经皮肾取石术治疗孤立的肾盏结石的方法和疗效。方法回顾总结22例采用B超引导微创经皮肾钬激光碎石取石术治疗孤立的肾盏结石。结石长径大小1．5～2．5cm，平均（2．1士0．3）cm，其中多发结石3例，肾盏积水（2．0～2．8）cm，平均（2．6士0．2）cm。其中上组盏结石3例，中组盏5例；下组盏16例。黠杲22例患者全部全部取石成功，术后4～7d复查腹部平片未发现残留结石，拔出肾造漏管。未发生大出血等严重并发症。手术时间26～45min，平均（34．6±5．2）min。术后住院5～8d，平均（6．1士2．1）d。瞎论微刨经皮肾取石术治疗孤立的肾盏结石安全、有效，适用于肾盏积水〉2cm、因解剖特点预期体外冲击波碎石效果不佳的肾盏结石患者。精准的经皮肾穿刺是成功的关键。

Objective To evaluate the feasibility and efficacy of mini-percutaneous nephrolithotomy （MPCNL） for isolated calyceal calculi. Methods Data of 22 patients with isolated calyceal calculi who had undergone MPCNL with ultrasonic guidance were retrospectively analyzed. Of the 22 cases, 3 had sup-calyceal calculi, 5 had meta.calyceal calculi and 16 hypo-calyceal calculi. The mean stone diameter was （2.1 ± 0.3）cm. The mean operation time was （34. 6 ±5.2）min. Results All operations succeeded. None of the 22 patients had residual calculi under KUB or complications such as massive hemorrhage. Conclusions MPCNL has advantages of minimal trauma, little blood loss, and few complications. It is safe and effective in treating isolated calyceal calculi.
