Usage of Modified Makuuchi Incision for Surgical Management of Complex Renal and Adrenal Lesions.

Background:  Modified Makuuchi (MM) incision is less popular among the urological fraternity as Chevron, subcostal, flank, and midline incisions are commonly used for most of the complex renal and adrenal conditions. We present our experience and report the outcomes of patients operated using this incision.

Materials And Methods:  The records of patients who underwent open surgery for upper abdominal urological conditions using MM incision over the last five years in our department were retrospectively reviewed. Patient demographics, laterality of the lesion, size of the lesion, level of inferior vena caval (IVC) thrombus, intraoperative blood loss, local tumor invasion, need for concomitant hepatectomy, need of diaphragmatic resection, use of self-retaining retractors, operative time, hospital stay, wound-related complications, and readmissions were analyzed.

Results:  Some 18 patients underwent open surgery by this incision for various complex renal and adrenal conditions during the study period. Patients included those with large upper pole renal and adrenal masses, renovascular conditions like renal artery aneurysm, renal/adrenal masses with liver and diaphragmatic infiltration requiring hepatectomy, diaphragmatic resections, or IVC thrombectomy. The mean size of renal and adrenal masses was 13.8 (±6.3) cm, mean operative time was 370 (±210.6) minutes, mean blood loss was 1124 (±990.3) mL, and mean hospital stay was 11.65 (±13.2) days. Four patients had surgical site infection (SSI) and one had readmission.

Conclusion:  The MM incision can be widely adapted for complex renal and adrenal surgeries and should become a part of the various commonly used incisions by urologists.
