Retroperitoneal Laparoscopic Nephrectomy

Introducing polymer ligating clips (PLC) or Hem-o-lok clips was a useful alternative to titanium clips in order to perform a safe, efficient and rapid ligation of the vascular structures during laparoscopic and/or conventional surgical procedures. In urologic surgery they are useful during ablative laparoscopic surgery for renal tumor, urothelial tumors, non-functional kidney, bladder tumors and prostate tumors. Polymers� properties depend on the structure of molecules and vary from flexible substances to expandable rigid materials. They have a high resistance to shock, considerable abrasion resistance and precise durability. Polymers can easily take the desired shape, due to different processing modes. They also have the property of resistance to sustainable action of external forces. The aim of this paper is to evaluate the efficacy and safety of PLC used during renal pedicle ligation in retroperitoneal laparoscopic nephrectomy for renal tumors, high urothelial tumors and nonfunctional kidney.

The authors present a review of foreign publications in 2010–2019 on laser light application in urology. The analyzed articles confirm its high efficiency, safety and competitiveness if to compare with traditional instruments in surgery of urological pathologies. The combinaiton of laser light and endoscope turned to be the most effective. Laser medical technologies are used for treating benign prostatic hyperplasia, urolithiasis, cicatricial lesions of the urinary tract, and urothelial tumors. There is a tendency in applying laser technologies more frequently in laparoscopic surgery.

The atomic force microscope (AFM) is an instrument that can be used to image many samples of interest in biology and medicine. Images of polymerized amino acids, polyalanine and polyphenylalanine demonstrate the potential of the AFM for revealing the structure of molecules. Images of the protein fibrinogen which agree with TEM images demonstrate that the AFM can provide topographical data on larger molecules. Finally, images of DNA suggest the AFM may soon provide an easier and faster technique for DNA sequencing.The AFM consists of a microfabricated SiO2 triangular shaped cantilever with a diamond tip affixed at the elbow to act as a probe. The sample is mounted on a electronically driven piezoelectric crystal. It is then placed in contact with the tip and scanned. The topography of the surface causes minute deflections in the 100 μm long cantilever which are detected using an optical lever.
