Polyuria with frequent and urgent urination typically results from increased total urine output. Conditions such as diabetes, diabetes insipidus, psychogenic polydipsia, and acute renal failure are primary causes of this symptom.
Inflammatory Polyuria and Polyuria
Inflammatory polyuria and polyuria primarily manifest as symptoms resulting from urinary tract infections or inflammation. Each urination episode involves a small volume of urine, and most inflammatory conditions are accompanied by urgency and dysuria. Microscopic examination of urine may reveal inflammatory cells. Key diseases associated with this type include cystitis, urethritis, prostatitis, and paraurethral gland inflammation.
Neurogenic Polyuria and Polyuria
Neurogenic polyuria and polyuria primarily result from neurogenic stimulation due to central or peripheral nerve lesions. This condition manifests as frequent urination with small volumes, without urgency or dysuria. Urinalysis shows no inflammatory cells.Common conditions include: hysteria, neurogenic bladder.
Bladder-restrictive polyuria and pollakiuria
Bladder-restrictive polyuria and pollakiuria primarily result from bladder space-occupying lesions. It manifests as persistent urgency and frequency with scant urine output, often resistant to medication. Common conditions include: enlarged uterus during pregnancy, bladder compression by ovarian cysts, and bladder fibrosis/constriction due to tuberculosis.
Urethral Orifice Lesion-Induced Polyuria and Polyuria
Urethral orifice lesions primarily cause polyuria and polyuria by irritating the urethral opening. Common conditions include urethral orifice polyps, hymenal vestibule, and paraurethral gland cysts.
