目的 探讨一次性电子输尿管软镜治疗老年患者2.0～3.0 cm非下盏肾结石的疗效和安全性.方法 2021年1月～2022年12月我院78例老年患者2.0～3.0 cm非下盏肾结石,按照术式分为FURL组[一次性电子输尿管软镜碎石术(flexible ureteroscope lithotripsy,FURL)42 例]和 MPCNL 组[微通道经皮肾镜碎石术(minimally invasive percutaneous nephrolithotomy,MPCNL)36例],比较2组手术时间、碎石时间、术后血红蛋白下降值、术后疼痛视觉模拟评分(Visual Analogue Scale,VAS)、住院时间、术后1周和4周结石清除率(stone free rate,SFR)、二次治疗率和并发症发生率等.结果 所有患者均顺利完成手术.FURL组血红蛋白下降值(4.4±1.6)g/L,显著低于MPCNL组(24.7±4.6)g/L(t=-25.342,P=0.000);FURL组术后疼痛VAS评分(1.6±0.4)分,显著低于MPCNL组(5.6±0.9)分(t=-25.642,P=0.000);FURL组碎石时间(82.5±10.2)min,明显长于 MPCNL 组(53.8±8.4)min(t=13.437,P=0.000);FURL 组手术时间(98.3±12.5)min,与MPCNL组(96.7±11.8)min比较差异无统计学意义(t=0.555,P=0,581);FURL组住院时间(3.5±1.5)d,显著短于MPCNL组住院时间(8.6±1.7)d(t=-13.947,P=0.000).FURL 组并发症发生率 26.2％(11/42),与 MPCNL 组 27.8％(10/36)差异无显著性(x2=0.025,P=0.875).FURL组二次治疗率19.0％(8/42),与MPCNL组11.1％(4/36)差异无显著性(x2=0.938,P=0.333).FURL 组术后 1 周 SFR 54.8％(23/42),明显低于 MPCNL 组 86.1％(31/36)(x2=8.943,P=0.003);FURL 组术后 4 周 SFR 90.5％(38/42),与 MPCNL 组 91.7％(33/36)差异无显著性(x2=0.000,P=1.000).结论 一次性电子输尿管软镜治疗老年患者2.0～3.0 cm非下盏肾结石效果显著,具有创伤小、恢复快、出血少、并发症发生率低、住院时间短等优势,值得在临床上推广应用.
Abstract
Objective To evaluate the efficacy and safety of single-used flexible ureteroscope lithotripsy(FURL)in the treatment of 2.0-3.0 cm non-lower-pole renal stones in elderly patients.Methods A total of 78 elderly patients with non-lower-pole renal stones measuring 2.0-3.0 cm admitted to our hospital were included in this study.Based on the surgical procedure,the patients were divided into the FURL group(42 cases of FURL with holmium laser lithotripsy)and the MPCNL group[36 cases of minimally invasive percutaneous nephrolithotomy(MPCNL)with holmium caser lithotripsy].Various parameters including operation time,stone fragmentation time,postoperative decrease of hemoglobin(Hb)level,postoperative Visual Analog Scale(VAS)for pain,hospitalization duration,stone-free rate(SFR)at 1 week and 4 weeks after surgery,secondary surgery rate,and incidence of complications were compared between the two groups.Results All the patients successfully underwent surgery.The decrease of Hb in the FURL group was(4.4±1.6)g/L,significantly lower than that in the MPCNL group[(24.7±4.6)g/L,t=-25.342,P=0.000].The postoperative VAS scores of the FURL group was(1.6±0.4)points,significantly lower than that of the MPCNL group[(5.6±0.9)points,t=-25.642,P=0.000].The stone fragmentation time in the FURL group was(82.5±10.2)min,significantly longer than that in the MPCNL group[(53.8±8.4)min,t=13.437,P=0.000].The operation time in the FURL group was(98.3±12.5)min,and there was no statistically significant difference compared to the MPCNL group[(96.7±11.8)min,t=0.555,P=0581].The hospitalization time in the FURL group was(3.5±1.5)d,significantly shorter than that in the MPCNL group[(8.6±1.7)d,t=-13.947,P=0.000].The incidence of complications in the FURL group was 26.2％(11/42),and there was no significant difference compared to the MPCNL group[27.8％(10/36),x2=0.025,P=0.875].The proportion of secondary treatment in the FURL group was 19.0％(8/42),and there was no significant difference compared to the MPCNL group[11.1％(4/36),x2=0.938,P=0.333].At 1 week after surgery,the SFR of the FURL group was 54.8％(23/42),significantly lower than that of the MPCNL group[86.1％(31/36),x2=8.943,P=0.003].At 4 weeks after surgery,there was no significant difference in SFR between the FURL group[90.5％(38/42)]and the MPCNL group[91.7％(33/36),x2=0.000,P=1.000].Conclusions Single-used flexible ureteroscope lithotripsy is highly effective in the treatment of non-lower-pole renal stones measuring 2.0-3.0 cm in elderly patients.It offers advantages such as minimal invasion,rapid recovery,minimal bleeding,low incidence of complications,and shorter hospitalization duration,which is worthy of promotion.
