1Department of Urology, Chonbuk National University Medical School and Research Institute of Clinical Medicine, Jeonju, Korea.
A giant ureteral stone caused severe pain and kidney issues in a 43-year-old man. Laparoscopic surgery successfully removed the large stone, resolving the obstruction and preserving kidney function.
Area of Science:
- Urology
- Nephrology
- Surgical Technology
Background:
- Ureteral stones can cause significant pain and complications.
- Giant ureteral stones are rare and pose unique diagnostic and treatment challenges.
- Kidney atrophy and hydronephroureterosis can result from prolonged ureteral obstruction.
Observation:
- A 43-year-old male presented with chronic left flank pain.
- Imaging revealed a large 6.2 x 2.2 cm left ureteral stone causing obstruction.
- Associated findings included right kidney atrophy and left hydronephroureterosis.
Findings:
- A left transperitoneal laparoscopic ureterolithotomy was successfully performed.
- The giant ureteral stone was completely removed.
- The procedure yielded excellent clinical results.
Implications:
- Laparoscopic ureterolithotomy is an effective treatment for giant ureteral stones.
- Early diagnosis and intervention are crucial to prevent kidney damage.
- Minimally invasive surgery offers a viable option for complex stone cases.
