Objective:

To report the experience with single-port robotic non-transecting Y–V flap pyeloplasty with stricturoplasty for primary ureteropelvic junction obstruction (UPJO), highlighting its significance in preserving vascular integrity.

Key Findings:
  • The non-transecting approach preserves ureteral blood supply, potentially reducing ischemic complications.
  • Single-port robotic systems enhance the feasibility of non-dismembered reconstruction.
  • The combination of Y-V flap pyeloplasty and stricturoplasty allows for effective management of UPJO, with promising postoperative outcomes.
Interpretation:

The study suggests that robotic single-port Y-V flap pyeloplasty with stricturoplasty is a viable technique for UPJO, preserving vascular integrity and potentially improving surgical outcomes, which may influence future surgical practices.

Limitations:
  • Retrospective study design may limit the robustness of findings and introduce selection bias.
  • Inconsistent availability of preoperative functional assessment data across patients may affect outcome evaluation.
Conclusion:

The study demonstrates the feasibility and potential advantages of robotic single-port Y-V flap pyeloplasty with stricturoplasty for managing primary UPJO, suggesting a shift in surgical approach for better patient outcomes.
