ABSTRACT
Giant bladder calculi are rare and long-term usage of cystostomy could cause stone formation. Due to the lack of evidence on giant bladder calculi and the long-term usage of cystostomy can cause bladder calculi formation, we provide a case study of a man with a neglected cystostomy with giant bladder calculi for 4 years. A fixed mass was discovered in the suprapubic region. Ultrasound examination revealed 4.1 × 5.5 cm bladder calculi and contracted left kidney. Bipolar voiding cystourethrography portrayed stricture in pars pendular and membranacea, uneven bladder wall, and 4.5 × 4.5 cm bladder calculi. The stone was extracted, and the bladder filling test revealed a small bladder capacity. Since the patient refused urethral reconstruction and bladder augmentation, he was discharged with another cystostomy catheter. Six-month follow-up revealed no forming stones. Neglected cystostomy catheter can cause giant bladder calculi. Prompt diagnosis and treatment should be made to manage this condition to reduce the likelihood of bladder cancer.
