Patients with prostatitis will not experience a decrease in urine output, but may experience an increase in the frequency of urination or symptoms such as urinary urgency, painful urination, and discomfort in the perineal area. Prostatitis does not cause kidney dysfunction, so the kidneys can perform their normal function of filtering the metabolic wastes, impurities, and water in the body to produce urine. Prostatitis will only cause localized symptoms, such as urethral dribbling or urinary tract irritation, etc. It will not jeopardize the safety of the kidneys or affect the function of the kidneys, so there will not be a decrease in urine output. It is recommended to go to the hospital for further examination to clarify whether there is renal failure or urinary tract obstruction, both of which can lead to low urine output, usually caused by the decline in renal function of low urine output can be accompanied by edema of the limbs or facial areas, and with the further aggravation of oliguria the degree of edema will also be aggravated. If the urinary tract obstruction caused by oliguria, such as prostate hypertrophy or urethral calculi, generally have a clear sense of holding urine, the kidneys produce a normal amount of urine, but the discharge is abnormal, so oliguria, it is recommended to go to the hospital to carry out a comprehensive examination to clarify the relationship with prostatitis.
