In a nutshell

This study aimed to find the risk factors for developing bladder stones (calculi) in patients with enlarged prostates. The study found that risk factors for bladder stones include urine infection and intravesical prostatic protrusion (IPP – enlarged prostate pushing into the bladder).

Some background

Bladder calculi are stones that form in the bladder. These are common in patients with benign prostatic hyperplasia (BPH – enlarged prostate). These stones negatively affect patients. It is necessary to assess the risk for developing bladder stones to avoid them.

Methods & findings

332 patients with BPH who had surgical treatment were analyzed. 94 (28.3%) patients had bladder calculi and 238 (71.7%) of patients did not have bladder calculi.Factors such as medical history, age, prostate size, IPP, bladder symptoms and urine were assessed.

IPP and urine infection were found to be factors that increased risk of bladder calculi in patients with BPH.

The bottom line

The study concluded that IPP and urinary tract infection were risk factors for developing bladder calculi in patients with BPH.

The fine print

The study was retrospective (looking back at old data) so patients could not be followed up for further study. The sample size was small and some patients urine was not checked.

What’s next?

Talk to your doctor about checking your urine and size of prostate before surgery.
