A major calyx stricture is a medical condition involving the narrowing of the major calyces in the kidneys. The kidneys contain structures called calyces, which collect urine before it moves to the bladder. When a major calyx becomes narrowed, it can hinder the flow of urine, leading to various health issues. This guide aims to provide a clear, straightforward explanation of major calyx strictures, covering their causes, symptoms, diagnosis, treatments, and more.
A major calyx stricture refers to an abnormal narrowing in the major calyces of the kidney. The major calyces are large chambers in the kidney that collect urine from smaller structures called minor calyces before it moves to the renal pelvis and then to the bladder. A stricture in this area can disrupt normal urine flow, potentially causing kidney damage.
Anatomy of the Kidney
To understand a major calyx stricture, it’s essential to grasp the basic anatomy of the kidney:
- Renal Cortex: The outer layer of the kidney where blood filtration begins.
- Renal Medulla: The inner region containing the pyramids and minor calyces.
- Minor Calyces: Small chambers that collect urine from the renal pyramids.
- Major Calyces: Larger chambers formed by the convergence of minor calyces, funneling urine into the renal pelvis.
- Renal Pelvis: The central cavity that channels urine into the ureter.
Pathophysiology of Major Calyx Stricture
Structure
A major calyx stricture occurs when scar tissue or other abnormalities cause the walls of a major calyx to become thickened and narrowed. This narrowing can impede urine flow, leading to increased pressure within the kidney.
Blood Supply
The kidneys receive blood through the renal arteries, which branch into smaller arterioles supplying the renal cortex and medulla. Proper blood flow is crucial for kidney function and healing processes.
Nerve Supply
The kidneys are innervated by autonomic nerves that regulate blood flow and urine production. Disruption in nerve supply can affect kidney function and pain perception.
Types of Major Calyx Stricture
- Congenital Strictures: Present at birth due to developmental abnormalities.
- Acquired Strictures: Develop later in life, often due to injury, infection, or disease.
- Benign Strictures: Non-cancerous narrowing caused by scarring or inflammation.
- Malignant Strictures: Caused by tumors or cancers affecting the kidney.
