Inclusion criteria

排除标准:

1.尿路感染未得到控制的患者,符合以下标准: 1.伴有尿路症状的患者:清洁中段尿培养:菌落计数≥10⁵ CFU/mL(单一致病菌);或清洁中段尿离心沉渣:白细胞酯酶(+)或尿白细胞计数≥10个/ HPF(高倍视野),且尿培养菌落计数≥10³ CFU/mL(单一致病菌); 2.无尿路症状的患者:连续 2 次清洁中段尿培养,均为同一单一致病菌,且菌落计数≥10⁵ CFU/mL;
2.对输尿管镜/软镜手术有绝对禁忌症的患者;
3.患者无法理解或配合试验的开展;
4.需要做经皮肾镜手术患者;
5.术后需要长期留置输尿管支架超过4周+2天的患者;
6.研究者认为可能存在增加受试者危险性或干扰临床试验的任何情况;

Exclusion criteria:

1. Patients with uncontrolled urinary tract infections (UTIs) who meet the following criteria: (1) Patients with urinary tract symptoms: Clean-catch midstream urine culture: colony count >= 10^5 CFU/mL (single pathogenic bacterium); OR centrifuged sediment of clean-catch midstream urine: leukocyte esterase (+) or urine leukocyte count >= 10 cells/HPF (high-power field), plus urine culture colony count >= 10^3 CFU/mL (single pathogenic bacterium). (2) Patients without urinary tract symptoms: Two consecutive clean-catch midstream urine cultures showing the same single pathogenic bacterium, with colony count >= 10^5 CFU/mL in both tests. 2. Patients with absolute contraindications to ureteroscopic/flexible ureteroscopic surgery. 3. Patients who are unable to understand or cooperate with the conduct of the trial. 4. Patients requiring percutaneous nephrolithotomy (PCNL). 5. Patients who need long-term indwelling ureteral stents for more than 4 weeks and 2 days after surgery. 6. Patients with any other conditions that the investigators believe may increase risks to the participants or interfere with the clinical trial.

随机方法(请说明由何人用什么方法产生随机序列):

本研究负责入组的研究者通过随机数生成器,随机生成1,2两个数字,1进入研究组使用带线输尿管支架,2则进入对照组使用普通输尿管支架。

Randomization Procedure (please state who generates the random number sequence and by what method):

The investigators responsible for patient enrollment in this study generated two random numbers (1 and 2) using a random number generator. Patients assigned the number 1 were allocated to the study group and received string-attached ureteral stents, while those assigned the number 2 were allocated to the control group and received conventional ureteral stents.
