まとめ
レーザー切除による尿道顕微鏡検査 (URS) は,腸内再発率 (IVR) に微小な影響を及ぼし,上管泌尿器官がん (UTUC) の根性腎臓切除術 (RNU) に比べて,全生存率 (OS) を有意に変化させない. これらの発見は,UTUC患者にとって安全な選択肢であることを示唆しています.
科学分野:
- 泌尿器科
- 腫瘍学
- 外科 革新
背景:
- 尿路上部がん (UTUC) の治療には,しばしば急性腎臓切除術 (RNU) が必要ですが,より侵襲的でない選択肢が求められます.
- UTUCのレーザーアブレーションによる尿道顕微鏡検査 (URS) の腫瘍学的アウトカムについては,さらなる説明が必要である.
研究 の 目的:
- UTUC患者におけるレーザー除去によるURSの腫瘍学的安全性を評価する.
- 腸内再発率 (IVR),RNU対治療比,全生存率 (OS) への影響を評価する.
主な方法:
- 1904人の患者を対象とした24の研究を体系的にレビューし,総合分析した.
- PRISMAのガイドラインに従い,手術後のインスティレーションのサブグループ分析とURSとRNUの比較を行った.
主要な成果:
- 全体のIVR率は23. 7%でした. プール分析では,IVR (0. 33),RNU対治療比 (0. 23),OS (0. 62) の効果サイズが示されました.
- URSは,RNUと比較してIVR (ES1.14) やOS (ES1.43) で統計的に有意な差異を示さなかった.
- URSサブグループにおける術後の挿入は,IVR (ES 0. 38) とRNU対治療比 (ES 0. 25) の低下と関連していた.
結論:
- レーザー除去によるURSは,UTUCにおけるIVR率に軽微な影響を及ぼします.
- URSとRNUを比較したところ,IVRやOSの有意な差異は認められなかった.
- URSは腫瘍学的結果を損なうことなく,UTUCの管理に安全に使用できます.

Urinary Tract Calculi VI: Surgical Management

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...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. 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. Intravenous Urography (IVU)Intravenous...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...
