概括
双极能量可能在尿道孔附近的膀瘤的穿尿管切除过程中比单极能量提供优势,可能降低水缩和上道泌尿管癌风险.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 手术技术 手术技术
背景情况:
- 尿道外切除 (TUR) 在膀瘤中很常见.
- 单极和双极能量对尿道孔附近瘤的结果的影响尚不清楚.
- 瘤和功能结果需要调查.
研究的目的:
- 为了比较TUR中的单极和双极能量,用于涉及尿路孔的膀瘤.
- 评估瘤结局,特别是上道泌尿瘤 (UTUC) 的发展.
- 评估功能性并发症,如新发的水缩症 (HN).
主要方法:
- 对112名接受TUR治疗的患者进行了回顾性分析,以发现孔参与的膀瘤.
- 第1组:46名患者接受单极能量治疗.
- 组2:66名接受双极能量治疗的患者.
主要成果:
- 第二组的平均瘤大小显著更大 (67.8毫米对45毫米).
- 在双相组中观察到较低UTUC发病率的趋势 (1名患者与5名患者相比).

Inflammatory Bowel Disease V: Surgical Management
917
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Urinary Tract Calculi VI: Surgical Management
1.0K
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Urologic Endoscopic Procedure: Cystoscopic Examination
6.6K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
