A cause of renal dysfunction: a giant bladder stone

Bladder stones are frequently seen in elderly men and account for 5% of all urinary stones. They develop secondary to infravesical obstructions, such as prostatic hyperplasia and neurogenic bladder. A 56-year-old patient with frequent and painful urination, dysuria, and minor complaints of suprapubic pain was referred to our clinic. He was diagnosed with bladder stones by non-contrast abdominopelvic computerized tomography, kidney-ureter-bladder radiography, and urinary system ultrasonography. Cystolithotomy was applied on a giant stone measuring 11×6.5×10 cm that filled the intravesical cavity nearly completely. Here, we present this case of a giant bladder stone causing renal dysfunction within the context of findings in the literature.
