Renal consequences of complex abdominal wall reconstruction

Area of Science:

• Surgical innovation
• Nephrology
• Abdominal wall reconstruction

Background:

• Complex abdominal wall reconstruction (AWR) is increasingly performed for large ventral hernias and loss of domain.
• Understanding the renal consequences of AWR is crucial for optimizing patient outcomes.

Purpose of the Study:

• To review the renal consequences of complex abdominal wall reconstruction (AWR).
• To examine how reconstructive mechanics, intra-abdominal pressure, perioperative fluid strategy, and baseline renal reserve influence postoperative kidney outcomes.

Main Methods:

• Focused narrative review of PubMed/MEDLINE and Embase databases.
• Searched for studies on AWR, hernia repair, intra-abdominal pressure, and renal outcomes.
• Manual screening of reference lists of key studies.

Main Results:

• Postoperative acute kidney injury (AKI) is common after complex AWR, particularly with extensive repairs.
• Renal vulnerability is linked to pressure stress, fluid management, and reduced renal reserve.
• Kidney injury may persist beyond the initial hospital stay in some patients.

Conclusions:

• Complex AWR is a physiologically demanding procedure with potential renal implications.
• Renal dysfunction post-AWR signals significant perioperative stress.
• Surgeons should carefully interpret oliguria and monitor high-risk patients for renal dysfunction.
