まとめ
膀腫瘍の切除後の直後の腸内化学療法 (IPOC) の輸液プロトコルは,ボラス療法よりも効果的で信頼性があります. この輸液法では,痛みを軽減し,治療中断率を低減し,非筋肉侵襲性膀がんの早期再発を防ぎます.
科学分野:
- 泌尿器科
- 腫瘍学
- 化学療法
背景:
- トランスウレータル膀腫瘍切除 (TURBT) は膀がんの標準的な処置である.
- TURBTの後,再発を減らすために,直接の腸内術後の化学療法 (IPOC) がしばしば投与されます.
- IPOCプロトコルの最適化は,治療効果と患者の耐性を高めるために不可欠です.
研究 の 目的:
- 2つの異なる直腸内術後の化学療法 (IPOC) の投与プロトコルにおける有効性と信頼性を比較する.
- 患者のアウトカムと腫瘍再発率に対する輸液対ボルスIPOCの影響を評価する.
主な方法:
- TURBTを受け,IPOCを受けた104人の患者を対象とした遡及的研究.
- 患者は2つのグループに分けられた. 輸液によるIPOC (n=50) とボラスによるIPOC (n=54).
- 評価されたアウトカムには,痛み,中止率,腫瘍再発率,特に非筋肉侵襲性膀がん (NMIBC) が含まれていた.
主要な成果:
- 輸液によるIPOC群は,ボлус群と比較して痛みの/膀刺激のスコア (VAS) が著しく低下したと報告した (p=0. 01).
- 投与中止率は,注射用IPOC群 (10. 0%) とボラス群 (25. 9%) (p=0. 04) で著しく低下した.
- 全体的に統計的に有意ではないが,輸液プロトコルでは,低リスクのNMIBC患者において,再発のない生存率が高く,再発率が有意に低下した傾向を示した (p=0. 04).
結論:
- 膀の刺激を軽減し,治療中断に有効です.
- 低リスクのNMIBCの早期再発率の有意な減少を示しています.
- この研究は,TURBTの後に,即座に腸内化学療法を行うための輸液プロトコルの使用を支持する.

Urologic Endoscopic Procedure: Cystoscopic Examination

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...

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...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
