Giant Bladder Calculus in a 70-year-old Female--A Case Report.

Vesical calculi are unusual in females, and giant calculi (weighing >100 g) are even more uncommon, considering the advances in contemporary diagnostic modalities. The entity is associated with a variety of pestering symptoms--frequency, dysuria, and hematuria, to name a few--causing serious effects on patients' quality of life. This report cites the case of an elderly female with a giant vesical calculus weighing 1.28 kg (12.5 cm in diameter). Our patient had no past surgical history or symptoms suggestive of bladder outlet obstruction or neurogenic bladder. As per our literature search, a stone as large as that of our patient has not yet been found in females. She underwent an uneventful open suprapubic cystolithotomy. A biopsy from a suspicious lesion during the surgery revealed squamous cell carcinoma. Given that such a large stone was found in an elderly female without any predisposing causative factors, it is worthwhile looking into the etiopathogenesis and management of giant vesical calculi.
