Summary
A rare kidney tumor, metanephric adenoma, was successfully treated in a 47-year-old patient using minimally invasive laparoscopic partial nephrectomy. This approach preserved kidney function while removing the tumor.
Area of Science:
- Urology
- Nephrology
- Surgical Oncology
Background:
- Metanephric adenoma is a rare, benign kidney tumor typically found in adults.
- Nephron-sparing surgery is the preferred treatment for localized renal tumors to preserve renal function.
Observation:
- A 47-year-old patient presented with a 3-month history of hematuria.
- Computed tomography identified an exophytic mass in the lower pole of the right kidney.
- Surgical removal revealed an encapsulated tumor with soft, pultaceous material.
Findings:
- Histological examination confirmed the mass as a metanephric adenoma.
- The patient underwent successful laparoscopic partial nephrectomy.
Implications:
- Laparoscopic partial nephrectomy is a viable and effective treatment for metanephric adenoma.
- This case highlights the importance of accurate diagnosis and minimally invasive surgical techniques for renal tumors.
- Preservation of renal parenchyma is crucial in managing benign renal neoplasms.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
