まとめ
腎臓小切開術 (UM-PCNL) は,腎臓小切開術 (S-PCNL) と比べて,0. 2~0. 5cmの腎臓小切開術で結石の発生率を比較することができます. UM-PCNLでは 病院での入院も減少し 血流も減少し 合併症も減りました
科学分野:
- 泌尿器科
- 侵襲 的 な 手術
- 腎結核の管理
背景:
- 標準的な皮経腎石切除 (S-PCNL) は大きな腎石に有効ですが,出血や症などのリスクがあります.
- ウルトラ・ミニ・パーキュタヌス・ネフロリトミー (UM-PCNL) は,より小さな経路を利用し,合併症を潜在的に軽減しますが,1.0-2.5cmの石に対する有効性はさらなる評価を必要とします.
研究 の 目的:
- UM-PCNLとS-PCNLを比較したランダム化比較試験を体系的にレビューし,メタ分析する.
- UM- PCNLとS- PCNLの安全性と有効性を評価し,結石の発生率と合併症の発生率に重点を置く.
主な方法:
- 2024年12月まで,PubMed,Embase,Cochrane Library,Web of Scienceを体系的に検索した.
- 628人の患者が参加した7つのランダム化対照試験 (RCT) がメタ解析に含まれました.
- ランダムまたは固定効果のモデルを使用して,プールされたオッズ比率と平均差を計算しました.
主要な成果:
- UM-PCNL と S-PCNL の間では,石抜き率 (SFR) の有意な差は認められなかった (P=0. 65).
- UM- PCNLでは, signicantly shorter hospitalization (P< 0. 001), 術後のヘモグロビンの低下 (P= 0. 0004),および全体的な合併症率の低下 (P= 0. 0003) が示されました.
- UM- PCNLは,手術後の発熱 (P=0. 04) と臓損傷のリスクを低下させ,手術期間や重度の出血の有意な差異は示されなかった.
結論:
- UM- PCNLは,1. 0 - 2.5cmの腎結石の治療に安全で効果的な代替薬です.
- UM-PCNLは,S-PCNLと比較して,短期間の入院,少量の失血,およびより低い合併症のリスクを含む,重要な利点を提供しています.

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...

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.

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)...

41
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. 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...

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...
