Total Differential Renal Function Ultrasound Warm Ischemia. Warm Ischemia Time The objective of surgical therapy is to excise the entire tumour with an adequate surgical margin. InRobson and colleagues established radical nephrectomy RN as the gold standard curative operation for localized RCC. In the past three decades, the increased use of imaging modalities such as ultrasound US and computerized tomography CT has led to increase the number of incidentally detected renal masses.
Tumours detected by imaging techniques tend to be smaller, lower stage lesions that are typically amenable to partial nephrectomy PN. The main aim of this surgical procedure is maximal preservation of unaffected renal parenchyma without sacrificing cancer control. During the last several years, refinements in the surgical technique of PN have made this procedure technically safe with acceptable complication rates. Long-term outcome data indicate that open partial nephrectomy OPN has cancer-free survival rates comparable to those of radical surgery with better preservation of renal function RFreduced frequency of cardiovascular events, and decreased overall mortality Technika Transuretral Prepact resection.
RN is no longer the gold standard treatment in these cases. It has been proved that, in these cases, NSS for tumours limited in diameter to 4 cm pt1a provides recurrence-free and long-term survival rates similar to those observed after radical surgery.
For larger tumours pt1bPN has demonstrated feasibility and oncological safety in carefully selected patients. The impact of laparoscopy has increased rapidly within the last two decades, and as a result, laparoscopic radical nephrectomy has become a recognized standard surgical approach by the EAU guidelines. Many laparoscopic surgeons were confronted with the situation that they could offer radical nephrectomy by means of laparoscopy but they had difficulties to perform laparoscopic NSS for the small tumors.
Thus, in the past few years, great efforts have been directed towards the 3 4 development of reliable and reproducible techniques for laparoscopic partial nephrectomy LPN AIM OF THE STUDY To learn the upper urinary tract laparoscopy from international leading urologists in the field, to overcome the learning phase and develop modifications of standard laparoscopic techniques. To design a study to answer some challenging questions in relation to the impairment of renal function after partial nephrectomy: a.
Application of Laparoscopy in Upper Urinary Tract Surgery
What is the minimal renal ischemia time which can lead to kidney damage? What is the maximum ischemia time which can be tolerated by the majority of kidneys?

Are there other factors which may worsen the damage? Are there renoprotective substances which can prolong ischemia time?

What is the impact of volume reduction on renal function outcome after partial nephrectomy? Ischemia time can be increased substantially by cooling of the renal parenchyma, which is easily induced during open surgery. When comparing laparoscopy with open surgery, ischemia time is longer even in the most experienced hands and hypothermia for protection of the renal function is difficult to Technika Transuretral Prepact resection.
Several attempts have been made to overcome the aforementioned problems in laparoscopic approaches. Cold ischemia is applied in cases where longer ischemic time is expected. The time available to complete the resection and repair of collecting system and parenchyma during warm ischemia is limited and the surgeon has to race against the clock. Renal cooling during ischemia protects the kidney and offers the surgeon extra time. The problem of renal cooling during ischemia when performing laparoscopic PN has not been solved yet.
Inwe presented our first experience with renal cooling during laparoscopic surgery for small RCC by means Technika Transuretral Prepact resection cold arterial perfusion. Patients and methods Between November and Marchwe performed laparoscopic PN in cold ischemia in 17 patients.
The indication was suspected RCC in 15 patients with a mean tumor size of 2. In all patients, preoperative angio-mri was performed to visualize the renal artery s. Preoperative renal scintigraphy DMSA was done to have a baseline data about the renal function for follow-up.
Placement of an open tip ureteric catheter was done under fluoroscopy to be used later to check the integrity of the collecting system.
Next, an angiocatheter was passed into the main renal artery through a femoral puncture on the ipsilateral side. This procedure was carried out by one of our interventional radiologists. Then the patient was brought to degree lateral decubitus position. In this final position for laparoscopic surgery, the angiocatheter was checked again and advanced in the renal artery close to the origin of the segmental arteries if needed. Port placement varied 5 6 according to the tumor location.
The renal artery was secured and later on occluded using a tourniquet.
Results and Discussion Laparoscopic PN with our technique could be performed successfully in all patients with no conversion. The mean intraoperative blood loss was ml 30 Only one patient required intraoperative blood transfusion.

Mean total ischemia time was 41 minutes min. Entry to the collecting system happened in 7 patients and was repaired intraoperatively. Mean amount of perfusate was 1, ml 1, Mean decrease of body temperature during cold perfusion was 0. Mean operative time was minutes.
