Introduction:
Neobladder urolithiasis is a rare but important delaying complication of orthotopic urinary diversion. We report a case of Hem-o-Lok (HOLC) migration into the neobladder with giant stone formation after orthotopic neobladder cystectomy.
Case Report:
We report a case of a 57-year-old man with frequent urination and occasional discharge of stones 3 years after a laparoscopic orthotopic neobladder cystectomy. Computed tomography revealed a large round 3.5 cm calculus. An endoscopic neocystolitholapaxy was performed, and a Hem-o-Lok was found in the center of the stone.
Conclusion:
We described the case presentation, treatment and analysis of etiology of stone formation to avoid such complication.
