Giant bladder stone of the «Jack stone» type: a clinical case

Bladder stones exhibit variability in size, morphology, and coloration, presenting either as solitary or multiple formations. The predominant configuration of bladder stones is spherical; however, in exceptional instances, they may manifest irregular radiating projections reminiscent of the components of the abroad children’s well-known game as Jacks. Consequently, such stones exhibiting an atypical stellate configuration have been designated as “Jack stones”. When formulating management strategies for patients presenting with large bladder stone and bladder outlet obstruction, it is imperative to consider the dimensions and composition of both the stone and the prostate, as well as the patients’ comorbidities, medical history, and structural anomalies of the lower urinary tract. The most employed surgical approaches for concurrent management include transurethral interventions on the prostate gland, transurethral or percutaneous cystolithotripsy, and open cystolithotomy. In the present study, we report our own clinical experience involving the removing of a large benign prostate hyperplasia [180 cc] and a giant bladder ‘’Jack stone’’ [50 mm in diameter], utilizing a combined endoscopic and open surgical approach.
