Retrograde intrarenal surgery for impacted upper ureteral stone in a patient with advanced lumbar scoliosis and lower-extremity development defect: a case report.

Yavuz Güler

J Med Case Rep 2022 May 26;16(1):204. Epub 2022 May 26.

Private Safa Hospital, Rumeli Universty, İstanbul, Turkey.

Background: Today, retrograde intrarenal surgery is the most preferred and very successful treatment method for upper ureteral stones that do not spontaneously pass and/or do not benefit from extracorporeal wave lithotripsy. However, perioperative complications are more common in retrograde intrarenal surgery if the stone in the ureter is impacted. Moreover, urosepsis and renal dysfunction are detected more frequently in patients with impacted stones. Read More
