[Renal function after laparoscopic partial nephrectomy with superselective balloon embolization of renal artery]

Area of Science:

• Urology
• Nephrology
• Surgical Oncology

Background:

• Partial nephrectomy is a key treatment for kidney neoplasms.
• Assessing renal parenchyma function post-surgery is crucial for patient outcomes.
• Surgical technique impacts renal function preservation.

Purpose of the Study:

• To compare renal parenchyma function after partial nephrectomy using two techniques.
• To evaluate the impact of superselective balloon embolization versus vascular clamping on kidney function.

Main Methods:

• A comparative study of 21 patients with T1-2N0M0 kidney neoplasms.
• Study group (n=11): Laparoscopic partial nephrectomy with superselective renal artery balloon embolization.
• Control group (n=10): Partial nephrectomy with vascular clamping (ischemia ≤ 20 min).
• Creatinine clearance and 1-minute diuresis were measured pre- and post-operation.

Main Results:

• Serum creatinine remained normal in both groups.
• Operated kidney creatinine clearance decreased 1.02-fold after embolization vs. 1.92-fold after clamping.
• 1-minute diuresis decreased by 43.53% after embolization vs. 83.21% after clamping.

Conclusions:

• Superselective balloon embolization preserves renal function more effectively than vascular clamping.
• No significant renal dysfunction was observed after superselective balloon embolization.
• This technique is a viable option for maintaining renal parenchyma function post-partial nephrectomy.
