Clinical Classification Guidelines
Inclusion Terms
- Kinking and stricture of ureter without hydronephrosis
Excludes Type 1
- Crossing vessel and stricture of ureter without hydronephrosis with infection (N13.6)
Medical Intelligence & Overview
ICD-10 code N13.5 refers to a condition characterized by a crossing blood vessel and a stricture in the ureter that does not result in hydronephrosis. The ureter is the tube responsible for carrying urine from the kidneys to the bladder. When there is a kink or narrowing (stricture) in this tube, it can affect the flow of urine, potentially leading to various urinary problems. However, in this specific condition, despite the presence of abnormalities, the kidney does not swell due to urine build-up, which is known as hydronephrosis.
Causes & Symptoms
Clinical Causes: Congenital abnormalities present at birth, such as abnormal positioning of blood vessels crossing over the ureter Degenerative changes in the ureter due to aging or wear and tear Injury or trauma to the ureter from accidents or surgical procedures Fibrosis or scarring from previous infections or inflammation External compression from neighboring tissues or tumors
Key Symptoms: Flank pain or discomfort, especially if the stricture tightens or causes partial obstruction Intermittent or persistent urinary symptoms such as urgency or frequency Urinary tract infections (UTIs), which may cause burning sensation or cloudy urine Reduced urine flow or difficulty urinating in some cases Asymptomatic in early stages, with symptoms developing if the stricture worsens
Diagnostic & Treatment
Diagnosis Path: Ultrasound imaging to evaluate kidney and ureter structures and rule out hydronephrosis Intravenous pyelography (IVP) or retrograde pyelography, which involves injecting contrast dye to visualize the ureter Computed tomography (CT) scan for detailed cross-sectional images Magnetic resonance urography to assess vessel positions and ureter integrity Urinalysis and urine culture tests to detect infections or abnormalities
Treatment Protocols: Watchful waiting for mild cases without significant symptoms or obstruction Endoscopic procedures such as balloon dilation or stenting to alleviate narrowing temporarily or permanently Surgical correction to reposition or repair the ureter and address crossing vessels or strictures Treating any underlying infections with appropriate antibiotics Regular monitoring through imaging studies to assess kidney health and ureter condition

Documentation
How do I report N13.5?
