Translated by Sarah Jenkins (AI RN Plain-English Translator) at a 7th-grade reading level
- 1 What it does: Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen.
- 2 Real-world patient consensus: Diagnostic registry K65.9: Peritoneal Disorders is managed within Kidney & Renal.
- 3 Typical cash cost range: Clinicians assessing Peritoneal Disorders focus on impaired nephron solute/acid-base in Peritoneal Disorders (K65.9: clearance) and targeted history.
- 4 Top reported side effects / signs: Longitudinal Peritoneal Disorders monitoring tracks Urine Albumin-to-Creatinine Ratio in Peritoneal Disorders (K65.9: (uACR)) toward < 15 mg/g (< 30 mg/g normal) (K65.9).

What Is Peritoneal Disorders?
Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue. Disorders of the peritoneum are not common. They include: Peritonitis - an inflammation of the peritoneum Cancer Complications from peritoneal dialysis Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
Pathophysiology, Underlying Causes & Clinical Presentation
In Peritoneal Disorders (K65.9), physiological disruption stems from impaired nephron solute/acid-base in Peritoneal Disorders (K65.9: clearance), Cross-referenced with NIH MeSH (Peritoneal Diseases), informing Chronic Kidney Disease & Electrolytes protocols that track Serum Potassium, Bicarbonate in Peritoneal Disorders (K65.9: & Phosphorus) (K+ 3.8–4.8 mEq/L; HCO3 23–29 mEq/L (K65.9)).
Common Symptoms & Clinical Signs
- • Peritonitis - an inflammation of the peritoneum
- • Complications from peritoneal dialysis
- • Presentation of Peritoneal Disorders (K65.9): fluid retention in in Peritoneal Disorders (K65.9: ankles, hands, or)
- • Secondary Peritoneal Disorders clinical sign: fatigue, muscle cramps, in Peritoneal Disorders (K65.9: metallic taste, or)
