Enlarged prostate with leakage stones may cause symptoms such as frequent urination, urgency, thin urine stream, etc. If combined with bladder stones it may lead to hematuria and urinary retention. Since the urethra is shaped from the middle of the prostate, when the prostate increases in size, it may cause the urethra to be compressed and narrowed, leading to thin urine stream and difficulty in urination, etc., and frequency of urination due to irritation of the urethra. Enlarged prostate can be complicated with prostate stones or bladder stones, generally patients with combined prostate stones often have no obvious symptoms of stones, while patients with combined bladder stones have hematuria due to the fact that the stones can bleed from the bladder mucosa with urine activity, and urinary retention can occur when obstruction is caused. Those who have the above symptoms may have prostate enlargement and other diseases, and need to consult the urology department in time.
