Assessing Renal Function Recovery Following Treatment for Post-Robot-Assisted Partial Nephrectomy Renal Artery...

Area of Science:

• Urology
• Nephrology
• Interventional Radiology

Background:

• Robot-assisted partial nephrectomy (RAPN) is a common procedure for kidney tumors.
• Renal artery pseudoaneurysm (RAP) is a rare but serious complication following RAPN.
• The long-term impact of RAP treatment on renal function after RAPN is not well understood.

Purpose of the Study:

• To evaluate the effect of RAP treatment on long-term renal function after RAPN.
• To compare renal function recovery in patients who developed RAP versus those who did not.

Main Methods:

• Retrospective review of 581 RAPN cases performed between February 2008 and February 2022.
• Analysis of patient variables, postoperative complications, and renal function (eGFR) at 1 day, 1 month, and 6 months post-RAPN.
• Statistical analysis using Fisher's exact test and Kruskal-Wallis rank sum test.

Main Results:

• 21 patients (3.61%) developed symptomatic RAP requiring Interventional Radiology embolization.
• No significant differences in baseline characteristics between RAP and non-RAP groups.
• Patients with RAP showed significantly reduced eGFR recovery at 1 and 6 months post-treatment compared to controls.

Conclusions:

• Treatment for RAP post-RAPN is associated with impaired renal function recovery.
• Patients treated for RAP experienced a greater decline in eGFR at 1 and 6 months.
• Further research is needed to optimize management strategies for RAP after RAPN.
