EXPERIENCE WITH A HISTOSCANNING APPARATUS USED IN THE DIAGNOSIS OF RECURRENT PROSTATE CANCER AFTER HIFU ABLATION

The new potentialities of 3D transrectal ultrasound study were realized in a HistoScanning diagnostic unit. It has been used at the R.M. Fronshtein Urology Clinic, Research Institute of Uronephrology and Reproductive Health, I.M. Sechenov First Moscow State Medical University, since September 2011. A study of the sensitivity and specificity of the technique enrolled patients undergoing high-intensity focused ultrasound (HIFU) ablation of the prostate of for its (PC) in the period 1 to 7 years. Prostate biopsy study with subsequent histology was made to confirm the results of histoscanning. Statistical processing of the obtained data showed that the sensitivity and specificity of histoscanning were 96 −100 and 87.5 −100%, respectively. These results allow one to appreciate histoscanning as a highly sensitive technique that advantageously differs in its significance level and informative value from now routinely used methods. The study on the possibility of planning and monitoring patients after focal treatments for PC opens up great prospects in achieving a balance between the radicality of performed surgery and the maintenance of quality of life in patients.
