Partial Kidney Resection Surgery | Asklepios Hospital Barmbek

At the Asklepios Hospital Barmbek in Hamburg, we prioritize preserving healthy organ function through partial kidney resection, also known as nephron-sparing surgery. When a kidney tumor is detected, the modern surgical goal is no longer the removal of the entire kidney, but rather the precise excision of the malignancy while saving as much functional renal tissue as possible. As a leading center for urological oncology, our clinic utilizes advanced robotic and laparoscopic platforms to ensure that patients maintain maximum kidney filtration capacity, which is vital for long-term cardiovascular health and the prevention of chronic renal failure. The surgical standard at Asklepios Barmbek for complex kidney tumors is the da Vinci Xi robotic system. This technology allows our surgeons to operate through several tiny incisions, providing a 3D, magnified view of the kidney’s intricate vascular network. During the procedure, the blood supply to the kidney is temporarily restricted, a phase known as "warm ischemia", to allow for a bloodless and precise removal of the tumor. Because the robotic instruments offer a greater range of motion than the human wrist, our surgeons can excise the tumor and suture the kidney back together with extreme speed and accuracy, minimizing the time the kidney is without blood flow and thus protecting its vital filtering units. For tumors located in less complex positions, we may utilize 3D laparoscopy, which offers a similarly minimally invasive profile with faster recovery times compared to traditional open surgery. Regardless of the chosen technique, we frequently employ intraoperative ultrasound directly on the surface of the kidney. This allows the surgeon to see beneath the tissue in real-time, identifying the exact boundaries of the tumor and the depth of its "roots. " By combining this "under-the-skin" visualization with robotic precision, we can often successfully perform partial resections on tumors that other centers might deem too difficult, necessitating a total kidney removal.
