A renal parenchymal sparing surgical approach may be recommended in select patients with von Hippel-Lindau disease and renal cancer or in those with sporadic renal cancer and limited normal renal function. We performed 27 partial nephrectomies or enucleations in 17 patients with the use of intraoperative ultrasound to examine a subset of all renal lesions identified on preoperative examination. Of 24 lesions deep in the renal parenchyma that were examined, localized or identified with intraoperative ultrasound 18 were characterized as cystic and 6 as solid. The deep cystic lesions were characterized with ultrasound as benign simple cysts. Intraoperative ultrasound was used to locate and mark the line of incision over 2 impalpable solid renal cell carcinomas. Four solid renal cell tumors extended deep into the renal parenchyma where color Doppler intraoperative ultrasound helped to define the plane of dissection adjacent to vital vascular structures. Renal hypothermia was not used in 3 renal operations based on intraoperative ultrasound findings.

A case of familiar bilateral multicentric RCC in a young woman is an ideal model to evaluate preoperative and intraoperative diagnostic and surgical tools in order to achieve two distinct goals: the oncologic radicalness and the renal function preserved. Radical bilateral nephrectomy, the renal hypothermia by perfusion of both kidneys, the bench high resolution sonography of parenchyma, the choose of one kidney suitable for conservative surgery, the resection of suspect lesions with intraoperative pathology, the reconstructive bench surgery, the autotransplantation, are the steps accurately performed with particular concern to eradication of all the tumoral lesions present in the kidneys. The results confirm that renal function has been preserved with this method. Radicalness should be appointed by a longlasting follow up. However, as it is discussed, conservative surgery, when accurately performed can give results not different from radical demolitive surgery. In this paper tools to improve diagnostic and therapeutic methods are described in order to increase the diagnostic accuracy and the therapeutic efficacy. The possibility that this multiple RCC can be a part of the abnormalities occurring in the Von Hippel-Lindau syndrome does not change the surgical approach, being the RCC the worst prognostic factor of the syndrome.

Contact Nd:YAG laser resection using the sapphire tip is nowadays a well-known method of partial nephrectomy. Our material consists of six patients (seven resections). The indication for the operation was a renal carcinoma in five patients (six resections) and renal changes of von Hippel-Lindau syndrome in one patient. Occlusion of the renal artery insured a good intraoperative haemostasis. This improved the cutting properties of the laser and made it more accurate. Low energy levels could be used. Thus the destruction of the renal parenchyma will be reduced. The mean follow-up time was 15.3 months. No local recurrences or distant metastases have been detected. In our hands the Nd:YAG contact laser combined with renal hypothermia is superior to traditional methods of partial nephrectomy.
