Abstract：
Percutaneous nephrolithotomy (PCNL) is an endourological method applied as the standard or tubeless method for kidney stone treatment. In a retrospective cohort study, 88 surgery units involving 75 children up to 18 years old with kidney stones who underwent the surgery for 8 years in Shahid Beheshti and Boo-ali hospitals in Hamadan with one of the two methods of standard or tubeless PCNL were evaluated and compared considering the success rate of operation, hemoglobin, hematocrit drop, need for medications, need for blood transfusion, duration of surgery, and the length of hospital stay. Among the 88 units studied, 47 cases were operated with the standard PCNL and 41 cases by tubeless method. In children operated by standard and tubeless PCNL, the complete success rate of operation was 87.2% and 100% (P = 0.006), the need for blood transfusion was 2.1% and 0% (P = 1.00), the need for opioids was 27.7% and 14.6% (P = 0.134), the decrease in hemoglobin was - 1.82 ± 0.94 and -1.30 ± 0.98 mg/dl (P = 0.024), the decrease in hematocrit was - 5.40 ± 2.66 and -3.52 ± 3.11 mg/dL (P = 0.003), the mean surgery duration was 109.30 ± 53.27 and 101.46 ± 31.92 min (P = 0.414), the duration of postoperative hospitalization was 3.38 ± 1.76 and 2.46 ± 1.27 days (P = 0.007), and the frequency of fever was 23.4% and 7.3% (P = 0.04), respectively. The success rate of kidney stone surgery in children with the tubeless PCNL is higher than the standard method, and its complications are lower.
摘要：
经皮肾镜取石术（PCNL）是一种泌尿外科方法，可作为肾结石治疗的标准或无管方法。在一项回顾性队列研究中，评估并比较了88个手术单元，涉及75名18岁以下的肾结石儿童，他们在哈马丹的ShahidBeheshti和Boo-ali医院接受了8年的手术，采用标准或无管状PCNL的两种方法之一进行了手术。手术成功率，血红蛋白,血细胞比容下降,需要药物，需要输血,手术持续时间,以及住院时间的长短。在研究的88个单位中，47例采用标准PCNL，41例采用无管法。在由标准和无内胎PCNL操作的儿童中，手术完全成功率分别为87.2%和100%(P=0.006),输血需求为2.1%和0%(P=1.00)，阿片类药物的需求量分别为27.7%和14.6%(P=0.134),血红蛋白下降为-1.82±0.94和-1.30±0.98mg/dl（P=0.024），血细胞比容下降为-5.40±2.66和-3.52±3.11mg/dL（P=0.003），平均手术时间为109.30±53.27和101.46±31.92min(P=0.414),术后住院时间分别为3.38±1.76和2.46±1.27天(P=0.007),发热频率分别为23.4%和7.3%(P=0.04),分别。无管化PCNL患儿肾结石手术成功率高于标准方法,其并发症较低。
