Tailoring technique of laparoscopic partial nephrectomy to tumor characteristics
Abstract
We use a tailored approach to laparoscopic partial nephrectomy based on tumor depth of penetration and proximity to the renal sinus. We evaluated differences in perioperative outcomes to determine the value of this paradigm. The surgical approach to hilar clamping and tumor bed management during laparoscopic partial nephrectomy included no clamp or suture, clamp with no suture, and clamp and suture. The end points assessed retrospectively were differences in perioperative, pathological and complication outcomes among these groups. Our surgical paradigm was used in 174 patients, including no clamp or suture in 36, clamp with no suture in 25, and clamp and suture in 113. Compared to the other patients those with a clamp and suture procedure were older with larger and deeper tumors that were closer to the renal sinus-collecting system and more likely to be malignant. Operative time was shortest in the no clamp or suture group and in the 2 clamp groups warm ischemia and operative times were shorter than in the no suture group. Estimated blood loss, hospital stay, surgical margins, complications and recurrences did not differ among the groups. A creatinine increase of 0.3 mg/dl or greater was seen in 33 patients (19%) following surg...Continue Reading

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.
Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
