The Usefulness of Three Dimensional Reconstruction Imaging using Spiral CT: an Experience in the Bilateral Wilms` Tumor Surgery / 대한비뇨기과학회지

ABSTRACT

Conventional angiography has been used to identify detailed vascular anatomy for surgery in which parenchymal salvage should be necessary. Recently, we experienced a case in which 3-dimensional CT was very helpful in salvaging the part of the kidney. A 2 year-old girl was diagnosed as bilateral Wilms` tumor. Conventional CT scan showed right huge mass and left upper pole mass of the kidney. The patient was planned to have neoadjuvant chemotherapy. Spiral CT scan with three-dimensional reconstruction was performed after 3-month chemotherapy and detailed anatomical information regarding vessels, tumor mass and normal parenchyma was obtained. Based on these anatomical information, right radical nephrectomy and left partial nephrectomy was successfully performed. Surgical findings was quite similar to that obtained by preoperative 3-dimensional CT images. Three-dimensional reconstruction of spiral CT imaging is considered to be useful in the evaluation of surgical anatomy in kidney-saving surgery preoperatively.
