摘要:目的? 探討Guy's結(jié)石評分(GS)預(yù)測經(jīng)皮腎鏡碎石取石術(shù)(PCNL)術(shù)后結(jié)石清除率及利用改良Clavien分級方法(MCC)預(yù)測PCNL術(shù)后并發(fā)癥發(fā)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(jié)石患者(160個腎單位),所有患者根據(jù)術(shù)前泌尿系CT結(jié)果應(yīng)用GS進行腎結(jié)石分組,利用術(shù)后KUB結(jié)果評估患者術(shù)后結(jié)石清除率,并且通過MCC預(yù)測患者術(shù)后并發(fā)癥的發(fā)生。結(jié)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(jié)石最大直徑:GS1=25 mm,GS2=28 mm,GS3=48 mm,GS4=69 mm,差異具有統(tǒng)計學(xué)意義(P<0.05)。根據(jù)GS進行數(shù)據(jù)分析,四組手術(shù)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(shù)[GS1=1個,GS2=(1.10±0.30)個,GS3=(1.20±0.50)個,GS4=(2.00±1.30)個],結(jié)石立即清除率(GS1=100.00%,GS2=87.30%,GS3=67.10%,GS4=66.70%),患者術(shù)后并發(fā)癥(GS1=6.70%,GS2=28.60%,GS3=31.50%,GS4=44.40%)比較,組間差異有統(tǒng)計學(xué)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(jié)石最終清除率比較,差異無統(tǒng)計學(xué)意義(P>0.05)。結(jié)論? GS和MCC可精確評估患者經(jīng)皮腎鏡術(shù)后結(jié)石清除率及有效預(yù)測患者術(shù)后并發(fā)癥的發(fā)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.
