Background: Various types of bladder stones have been described; however, development of large or “giant” bladder stones weighing 100 g or more are uncommon. There are only few cases of “giant” bladder stone causing renal failure reported in the literature.
Case Report: We report a a 68 year old male patient who presented with end-stage renal failure due to giant bladder stone which is possibly developed secondary to enlargement of prostate. The extirpated stone weighed 620 gram, and measured 110x85x70 mm in size.
Conclusions: Bladder stones may reach enormous sizes before causing symptoms that facilitate diagnosis. Patients with giant bladder stones may present with lower urinary tract symptoms, recurrent urinary tract infection, retention of urine, azotemia and even renal failure as was seen in
our case.
