研究目的: |
探讨新型可弯曲负压吸引输尿管软镜鞘在RIRS治疗肾结石复杂病例中的有效性和安全性,为传统RIRS难以解决的临床情况提供新思路。 |

Objectives of Study: |
To investigate the effectiveness and safety of a novel flexible negative pressure suction ureteral flexible sheath in complex cases of renal calculi treated by RIRS, and to provide new ideas for clinical situations that are difficult to solve by conventional RIRS. |
||||||||||||||||||||||
|
药物成份或治疗方案详述: |
新型可弯曲负压吸引输尿管软镜鞘(UAS)的治疗方案:由具有15年以上输尿管软镜手术(RIRS)经验的泌尿外科医生在全麻下经柔性可弯曲负压吸引UAS辅助下进行RIRS手术。手术程序按照标准RIRS顺序进行,前瞻性记录患者人口学及围手术期资料,包括结石大小、结石密度、结石部位、偏侧性、手术时间、出血量、胃肠功能恢复时间、并发症、住院时间及住院费用。手术时间定义为从第一个切口到所有切口闭合的时间。胃肠功能恢复时间定义为患者从离开手术室到第一次排气或排便的时间。所有术后并发症均根据Clavien-Dindo评分进行监测和分级。监测治疗发生的不良事件(TEAEs)。尿路感染定义为尿培养阳性,细菌计数为>105集落形成单位/ml,每高倍视野>5白细胞,和/或提示尿路感染的症状。术后2w返院复查尿路平片或CT平扫确认结石排出情况并拔除输尿管支架,术后2、4、6w对患者进行电话随访。 |

Description for medicine or protocol of treatment in detail: |
Treatment protocol for the new bendable negative pressure suction ureteral flexible sheath (UAS): The RIRS procedure is performed by a urologist with more than 15 years of experience in ureteral flexible surgery (RIRS) under general anesthesia with the assistance of a flexible bendable negative pressure suction UAS. The procedure was performed according to the standard RIRS sequence, and patient demographic and perioperative data were prospectively recorded, including stone size, stone density, stone site, laterality, operative time, bleeding, time to recovery of gastrointestinal function, complications, length of hospital stay, and hospital costs. Operative time was defined as the time from the first incision to the closure of all incisions. Gastrointestinal recovery time was defined as the time from the time the patient left the operating room to the time of the first defecation or bowel movement. All postoperative complications were monitored and graded according to the Clavien-Dindo score. Treatment-emergent adverse events (TEAEs) were monitored. Urinary tract infection was defined as a positive urine culture with a bacterial count of >105 colony-forming units/ml, >5 white blood cells per high-powered field, and/or symptoms suggestive of urinary tract infection. Patients were returned to the hospital 2w postoperatively for follow-up urogram or CT scan to confirm stone expulsion and removal of ureteral stent, and were followed up by telephone 2, 4 and 6w postoperatively. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
1.数据填写要求 对所有进入试验的患者,均须参照CRF的填写说明,认真、详细记录CRF中的所有项目,CRF中所有数据需与受试者病历数据核对,保证无误。 已经审核的CRF交数据管理员,数据管理员对日期、入组标准、剔除标准、脱落标准、缺失值等进行检查。 2.数据库的建立 根据病例报告表表格的项目采用医渡云科研协作平台建立相应的录入程序,并设定录入时的逻辑审查限定条件,对数据库进行试运行,进而建立本试验专用的数据库系统。在完成至少5份CRF后,应通过临床监查员及时送到,以便建立相应的数据库。 3.数据的录入与审核 由数据管理员进行数据同步录入,采用两次录入法。对数据库采用医渡云科研协作平台中的核查功能进行每一项目的查对,对报告不一致的结果值逐项核对原始调查表,以确保数据库中的数据与调查表中的结果一致。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data filling requirements For all patients entering the study, all items in the CRF shall be carefully and carefully recorded according to the filling instructions of the CRF. All data in the CRF shall be checked with the medical records of the subjects to ensure that they are correct. 2. Establishment of database According to the items in the case report form, Yidu Cloud Research Collaboration Platform was used to establish the corresponding entry procedure, and the logical review restriction conditions were set during the entry, and the database was run on a trial basis, and then a special database system was established for this experiment. After at least 5 CRFS have been completed, they should be sent through the clinical monitor in time for the establishment of the corresponding database. 3. Data entry and review The data manager shall enter the data synchronously, using the double entry method. The verification function in Yidu Cloud Research Collaboration Platform is used to check each item in the database, and the original questionnaire is checked item by item against the reported inconsistent result values to ensure that the data in the database is consistent with the results in the questionnaire. |
