Comparison of retroperitoneal laparoscopy with flexible ureteroscopy for treating renal pelvis cysts: superior perioperative outcome with a comparable recurrence rate

Key Points

• Retroperitoneal laparoscopic decortication significantly improved perioperative outcomes compared to flexible ureteroscopy, enhancing safety.
• Long-term recurrence rates were found to be comparable between retroperitoneal laparoscopy and flexible ureteroscopy.
• The treatment focuses on peripelvic cysts, improving patient outcomes without increasing recurrence risks.
• Findings may influence clinical decisions regarding the best approach to treating renal pelvis cysts.
