まとめ
この研究では,腎臓石の除去のための直接吸管 (DISS) の使い捨ての柔軟な尿管顕微鏡が評価されました. DISSのスコープはほとんどの石を効果的に移動し,避難させましたが,下極のより大きな断片はさらなる調査を必要としています.
科学分野:
- 泌尿器科
- 医療機器
- エンドウロロジー
背景:
- 柔軟な尿管顕微鏡は 腎石の治療に不可欠です
- 直接視野内吸入 (DISS) 技術は,尿管顕微鏡検査中に石破片の管理を改善することを目的としています.
研究 の 目的:
- DISSを搭載した単回用 7. 5 Fr 柔らかい尿管鏡の吸入性能を評価する.
- 腎臓石の断片の移転と排出におけるDISSの有効性を in vitroモデルで示す.
主な方法:
- 統合されたDISSを搭載した7. 5 Frのデジタル柔軟性尿管顕微鏡を用いた in vitro試験.
- 豚の尿管セグメントと3〜5ミリメートルの天然石の断片を使用した.
- 試行は石を上部,中部,下部に配置し,移転と避難の成功を評価しました.
主要な成果:
- 石の断片 (3 - 5 mm) は,DISSを使用して,すべてのカップから順調に移動されました.
- すべての場所から 3-4mmの断片を 避難させることに成功しました
- 5ミリメートルの断片は上部と中部から完全に排出されましたが,下部から一貫して排出されませんでした.
結論:
- 7.5 Fr Pusen DISSのスコープは,3〜5ミリメートルの石の断片を効果的に移動させます.
- 脱出の成功は,破片の大きさと位置に依存し,下極の5mmの破片に問題がある.
- DISS技術を使用したより大きな断片と下部のポールストーンを最適に管理するには,さらなる評価が必要です.

Urinary Tract Calculi VI: Surgical Management
26
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
336
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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography
144
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.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

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...
