To evaluate the role of Doppler ultrasound in reducing hemorrhagic events during percutaneous nephrolithotomy (PCNL) in solitary kidney calculi through a comparative analysis.
We retrospectively reviewed the charts of urolithiasis patients who had undergone ultrasound-guided PCNL in our department from March 2021 to December 2024 and identified 76 eligible patients. Patients were stratified into two cohorts based on Doppler flow detection technology application: Group 1 (Doppler-mode, = 29) and Group 2 (conventional mode, = 47). Relevant patient characteristics, operative variables, and postoperative data were collected and analyzed, focusing on bleeding complications and stone-free rate (SFR).
No significant difference was found between the two groups regards to basic characteristics (gender, age, body mass index, stone size, pre-operative serum creatinine). The puncture time shows significant longer in Group 1 compared to Group 2 (173.1 ± 39.6 vs. 111.4 ± 29.9 s, = 0.02). However, the hemoglobin loss reveals no significant difference between the two groups (17.5 ± 5.6 vs. 21.7 ± 6.3 g/L, = 0.19). There were no significant differences in the operation duration ( = 0.47), transfusion rate ( = 0.15), postoperative creatinine ( = 0.80), overall complication ( = 0.07), final stone-free rates ( = 0.38) between the two groups.
Doppler flow technology fails to confer superior benefits in ultrasound-guided PCNL for solitary renal calculus, with no definitive necessity established for hemorrhage risk mitigation.
通过对比分析，评估多普勒超声在减少孤立肾结石经皮肾镜取石术（PCNL）期间出血事件中的作用。
我们回顾性分析了2021年3月至2024年12月在我院接受超声引导下PCNL的尿路结石患者的病历，确定了76例符合条件的患者。根据多普勒血流检测技术的应用情况，将患者分为两组：第1组（多普勒模式，n = 29）和第2组（传统模式，n = 47）。收集并分析相关患者特征、手术变量和术后数据，重点关注出血并发症和结石清除率（SFR）。
两组在基本特征（性别、年龄、体重指数、结石大小、术前血清肌酐）方面无显著差异。与第2组相比，第1组的穿刺时间明显更长（173.1±39.6 vs. 111.4±29.9秒，P = 0.02）。然而，两组之间的血红蛋白损失无显著差异（17.5±5.6 vs. 21.7±6.3 g/L，P = 0.19）。两组在手术时长（P = 0.47）、输血率（P = 0.15）、术后肌酐（P = 0.80）、总体并发症（P = 0.07）、最终结石清除率（P = 0.38）方面均无显著差异。
在超声引导下的孤立肾结石PCNL中，多普勒血流技术未能带来更好的益处，在降低出血风险方面没有明确的必要性。
