Abstract

Objective: To describe the clinical characteristics, imaging, and treatment outcomes of bladder stones using endoscopic mechanical lithotripsy at Thai Binh Medical University Hospital. Subjects and methods: A retrospective, descriptive, cross-sectional study of 53 patients diagnosed and treated for bladder stones using endoscopic mechanical lithotripsy at Thai Binh Medical University Hospital from 1/ 2022 to 6/2024. Results: The most common reasons for admission were dysuria (50.9%), followed by urinary obstruction (3.8%). Very hard stones accounted for 25.5%. The most common stone size was 1-2 cm (66.1%). Single stones accounted for 81.1%. The stone fragmentation rate was 100%, with no intraoperative complications. The average surgical time was 36.4 ± 9.5 minutes. The average postoperative duration was 4.4 ± 1.4 days. The postoperative complication rate was 9.5%. The treatment outcomes at discharge were mostly good, accounting for 90.5%. Conclusion: The clinical and imaging manifestations of bladder stones are quite diverse and non-specific. Treatment of bladder stones by mechanical lithotripsy is an effective method with a relatively low complication rate.
