Summary
Retroperitoneoscopic ureterolithotomy offers a minimally invasive approach for impacted upper ureteral stones. This technique successfully removed stones with minimal postoperative pain, suggesting its utility as an alternative treatment.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Impacted upper ureteral stones pose a clinical challenge.
- Traditional surgical interventions can involve significant morbidity.
Purpose of the Study:
- To evaluate the feasibility and outcomes of retroperitoneoscopic ureterolithotomy for impacted upper ureteral stones.
Main Methods:
- Retroperitoneoscopic ureterolithotomy performed using Gaur's procedure with balloon dissection and four ports.
- Impacted stones removed via ureteral incision with a hook electrode.
- Ureteral stenting and retroperitoneal drain placement without ureteral suturing.
Main Results:
- Successful stone removal in two patients with impacted upper ureteral stones.
- Postoperative urine leakage resolved within three days.
- Complications included wound infection (MRSA) in one patient and psoas abscess in another.
Conclusions:
- Retroperitoneoscopic ureterolithotomy is a viable alternative for impacted upper ureteral stones.
- The procedure is associated with minimal postoperative pain.
- Careful patient selection and monitoring are necessary due to potential complications.
