  摘要:目的  探討Guy's結石評分(GS)預測經皮腎鏡碎石取石術(PCNL)術后結石清除率及利用改良Clavien分級方法(MCC)預測PCNL術后并發癥發生的可靠性。方法  選取2015年1月~2016年12月我院收治的155例行PCNL的腎結石患者(160個腎單位),所有患者根據術前泌尿系CT結果應用GS進行腎結石分組,利用術后KUB結果評估患者術后結石清除率,并且通過MCC預測患者術后并發癥的發生。結果  160個行PCNL的腎單位中,GS1、GS2、GS3及GS4分別為15、63、73和9個。每個組的結石最大直徑:GS1=25 mm,GS2=28 mm,GS3=48 mm,GS4=69 mm,差異具有統計學意義(P<0.05)。根據GS進行數據分析,四組手術時間[GS1=(32.50±14.10)min,GS2=(55.80±29.70)min,GS3=(80.80±35.10)min,GS4=(116.30±54.80)min],通道數[GS1=1個,GS2=(1.10±0.30)個,GS3=(1.20±0.50)個,GS4=(2.00±1.30)個],結石立即清除率(GS1=100.00%,GS2=87.30%,GS3=67.10%,GS4=66.70%),患者術后并發癥(GS1=6.70%,GS2=28.60%,GS3=31.50%,GS4=44.40%)比較,組間差異有統計學意義(P<0.05)。首次PCNL失敗的患者,無論最終再次PCNL成功與否,患者的結石最終清除率比較,差異無統計學意義(P>0.05)。結論  GS和MCC可精確評估患者經皮腎鏡術后結石清除率及有效預測患者術后并發癥的發生。

  Abstract:Objective  To investigate the accuracy of Gus's stone score (GS) in predicting stone clearance after percutaneous nephrolithotomy (PCNL) and the reliability of postoperative complications of PCNL using modified Clavien classification (MCC). Methods  A total of 155 patients with PCNL kidney stones (160 nephrons) admitted to our hospital from January 2015 to December 2016 were enrolled.All patients underwent GS for renal calculus according to preoperative urinary CT findings. Postoperative KUB results were used to evaluate postoperative calculus clearance, and MCC was used to predict postoperative complications. Results  Among the 160 nephrons of PCNL, GS1, GS2, GS3 and GS4 were 15, 63, 73 and 9 respectively. The maximum diameter of the stones in each group: GS1=25 mm, GS2=28 mm, GS3=48 mm, GS4=69 mm, the difference was statistically significant (P<0.05). According to GS data analysis, four groups of operation time [GS1=(32.50±14.10)min, GS2=(55.80±29.70)min, GS3=(80.80±35.10)min, GS4=(116.30±54.80)min], the number of channels [GS1=1, GS2=(1.10±0.30), GS3=(1.20±0.50), GS4=(2.00±1.30)], stone removal rate immediately (GS1=100.00%, GS2=87.30%, GS3 =67.10%, GS4=66.70%), the postoperative complications (GS1=6.70%, GS2=28.60%, GS3=31.50%, GS4=44.40%) were statistically significant (P<0.05).For the first time patients with PCNL failed, no matter whether the final PCNL was successful or not, the final clearance rate of the patients was not statistically significant (P>0.05). Conclusion  GS and MCC can accurately assess the rate of stone removal after percutaneous nephrolithotomy and effectively predict the occurrence of postoperative complications.
