#irregular urination
- Anisuria — A clinical symptom manifested by irregular and extreme variations in the volume of urine excreted within equal time intervals or from day to day, without correlated changes in fluid intake. This structural excretory imbalance indicates dysfunctions of the renal parenchyma, disruptions in antidiuretic hormone secretion, or instability in glomerular filtration mechanisms, requiring complete urological and metabolic evaluation.
