BPH & Bladder Stone

72 year old man presented with haematuria and passing out blood clots.
He is a known case of BPH – benign prostatic hyperplasia.
Ultrasound done showed an enlarged prostate with a volume of 83cc (normal <30cc).
In addition, there is also a 2.8cm stone in the bladder.
Bladder calculi is one of the most common urolithiasis in men over 50 years old.
The higher incidence is related to bladder outlet obstruction, inducing UTI and act as the initiating factor for stone formation.
Interestingly, the risk of stone formation is related to the intravesical prostatic protrusion (IPP). The longer the prostate protrudes above the bladder base, the higher the risk of stone formation.
