Recently I was having left testicle pain and lower abdomen pain .so my general physician asked to perform USG ABODMEN and pelvis also USG scrotal Doppler . In USG they gave finding of 2mm and 3mm stones on left kidney with thick walled urinary bladder . And enlarged prostate measured 3.7×3.7×3.7 cm, volume 27.6cc. I want to know what is the cause of prostate enlargement and what further steps need to be done further to shrink it prostate to normal.
