RESULTS OF EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY (ESWL) FOR LOWER THIRD URETERAL STONE AT HIEP HOA MEDICAL CENTER
Main Article Content
Abstract
Ureteral stones in the lower third are common conditions that can cause complications such as hydronephrosis, pyonephrosis, and impaired renal function if not treated promptly. Extracorporeal shock wave lithotripsy (ESWL) for treating lower third ureteral stones is a preferred non-invasive treatment method due to its high effectiveness, low complication rate, rapid recovery time, and cost efficiency. Objective: To evaluate the outcome of ESWL treatment for lower third ureteral stones using the HD.ESWL – 109 Kingkong machine at Hiep Hoa Medical Center. Subjects & Methods: This is a clinical interventional, non-controlled study. A total of 126 patients with lower third ureteral stones were treated with ESWL between June 2024 and June 2025. Stone clearance was assessed by KUB X-ray and ultrasound 4 weeks after the intervention. Results: The mean age was 47.13 ± 12.5 years; 65.9% were male and 34.1% female. Twenty-five percent had a history of urinary stone treatment before lithotripsy. Clinical symptoms included dysuria in 77.8%, renal colic in 54%, lumbar pain in 47.6%, and hematuria in 26.2%. Ultrasound showed grade I hydronephrosis in 42.1%, left ureteral stones in 64.3%, single stone in 98.4%, and stone size <10 mm in 88.9%. The single-session stone-free rate was 87.3%, with 12.7% residual stones. Complications included hematuria after lithotripsy in 12.7% and renal colic in 13.5%. Conclusion: ESWL for lower third ureteral stones is an effective and safe treatment method.
