Nocturnal polyuria
ICD-10 R35.81 is a billable code used to indicate a diagnosis of nocturnal polyuria.
Nocturnal polyuria is characterized by the excessive production of urine during the night, leading to frequent awakenings to urinate (nocturia). This condition can significantly disrupt sleep and may be indicative of underlying health issues. It is often defined as a nocturnal urine output that exceeds 33% of the total daily urine output. Common symptoms include increased nighttime urination, which can lead to sleep disturbances, fatigue, and decreased quality of life. The condition can be caused by various factors, including fluid intake before bedtime, medications (such as diuretics), hormonal imbalances (like decreased antidiuretic hormone), and underlying medical conditions such as diabetes mellitus, heart failure, or chronic kidney disease. A thorough clinical evaluation, including a detailed patient history and urinalysis, is essential for diagnosis. Laboratory findings may reveal abnormalities in urine concentration or volume, and a 24-hour urine collection may be necessary to assess total urine output. Understanding the etiology of nocturnal polyuria is crucial for effective management and treatment.
Detailed patient history, including fluid intake, medication review, and comorbid conditions.
Patients presenting with sleep disturbances and frequent nighttime urination.
Consideration of chronic conditions such as diabetes or heart failure that may contribute to nocturnal polyuria.
Acute assessment of urinary symptoms, including onset, duration, and associated symptoms.
Patients presenting with acute urinary retention or severe nocturia affecting sleep.
Rapid evaluation of potential acute causes such as urinary tract infections or exacerbation of chronic conditions.
Used to evaluate urinary symptoms including nocturnal polyuria.
Document the reason for urinalysis and any relevant findings.
Consider additional tests based on findings, such as urine culture.
The primary symptom is the excessive production of urine during the night, leading to frequent awakenings to urinate.
Diagnosis involves a detailed patient history, urinalysis, and possibly a 24-hour urine collection to assess total urine output.
Common causes include diabetes mellitus, heart failure, chronic kidney disease, and certain medications.
It can lead to sleep disturbances, fatigue, and decreased overall quality of life due to frequent nighttime awakenings.
