まとめ
上部管内がん (UT-CIS) は,終身モニタリングを必要とする広範な疾患です. UT-CISの疑いのある症例における尿道顕微鏡検査 (URS) の実施は,早期の手術と不必要な急性腎臓切除術 (RNU) の回避を含む利益をもたらしました.
科学分野:
- 泌尿器科
- 腫瘍学
背景:
- 上部経路がん in situ (UT-CIS) は診断に問題がある.
- その行動と結果を理解することは 患者の管理に不可欠です
研究 の 目的:
- 臨床的にUT-CISの疑いのある疾患の行動と腫瘍学的アウトカムを明らかにする.
- 尿管顕微鏡 (URS) の役割と効果を評価する.
主な方法:
- UT-CISの疑いのある48人の患者で実施された多施設の遡及研究 (2008年 - 2018年).
- URSを受けた患者とURSを受けなかった患者の比較
- 自然史とURSの影響に関するKaplan-Meier分析
主要な成果:
- URSを受けた28人の患者のうち,7人はUT- CISが確認され,6人はUT- CISではない.
- 膀の再発 (40%) と進行 (17%) が最も一般的であった.
- 生存結果は類似したが,URSは11%で早期手術を容易にし,11%でRNUを回避した.
結論:
- UT-CISはパン・ウロテリア疾患で,頻繁に再発し,進行し,長期の監視が必要である.
- 全体生存率は比較可能でしたが,URSは特定の患者亜群で有意な利点をもたらしました.

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.

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

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...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

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...

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...

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...
