まとめ
炎症性腸疾患(IBD)患者における消化管切除術は、結石負荷の増加や再発率の上昇を含め、尿路結石症の重症度を有意に増加させる。これは、これらの患者に対するサーベイランス強化と予防戦略の必要性を浮き彫りにするものである。
科学分野:
- 消化器病学および泌尿器科学; 外科的転帰研究
背景:
- 炎症性腸疾患(IBD)と尿路結石症との間には既知の関連が存在する。; IBD患者における過去の消化管(GI)切除術が尿路結石症重症度に与える影響は十分に理解されていない。
研究 の 目的:
- IBD患者における消化管切除術と尿路結石症重症度との関連を調査すること。
主な方法:
- 尿路結石症を有するIBD患者42名を対象とした後ろ向きコホート研究(2016-2024年)。; 患者は腸切除術の既往(小腸、回盲部切除術、結腸切除術)によって分類された。; 評価されたアウトカム:結石負荷、手術の必要性、再発、臨床イベント、および経皮的腎砕石術。回帰分析を使用した。
主要な成果:
- 患者の48%が腸切除術の既往があり、31%が複数回の切除術を受けていた。; 過去の腸切除術は、有意に高い結石負荷(p < 0.001)、手術の必要性の増加(p = 0.03)、および結石再発率の上昇(p = 0.006)と相関していた。; 多変量解析により、腸切除術が不良な尿路結石症アウトカムを独立して予測することが確認され、小腸および回盲部切除術は結腸切除術よりも強い関連を示した。
結論:
- 消化管切除術はIBD患者における尿路結石症重症度の増加と関連している。; 所見は、腸切除術の既往のあるIBD患者に対する積極的な予防療法とより厳格なサーベイランスの必要性を示唆している。

Inflammatory Bowel Disease V: Surgical Management
438
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Urinary Tract Calculi VI: Surgical Management
366
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
191
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)...

Chronic Bowel Disorders: Introduction
743
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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...
