A prostate of 48mm x 38mm x 27mm is generally not normal. This is because under normal circumstances, the size of the prostate gland in an adult man should be around 40mm x 30mm x 20mm, and anything smaller or larger than this size is considered abnormal. Prostate 48mmx38mmx27mm is generally benign prostatic hyperplasia, benign prostatic hyperplasia patients often have obvious symptoms of frequent urination, urinary urgency, such as obstruction for a long time failed to release, the forced urethral muscle may atrophy, resulting in the bladder can not be emptied and residual urine. As the amount of residual urine increases, the bladder atonic enlargement, filling incontinence can occur, and in severe cases, it can cause upper urinary tract fluid and renal function impairment. Therefore, when an abnormality is detected in the prostate, treatment should be carried out under the guidance of a doctor.
