[3D-TECHNOLOGIES AS A CORE ELEMENT OF PLANNING AND IMPLEMENTATION OF VIRTUAL AND ACTUAL RENAL SURGERY].

The purpose of this article is to demonstrate the role of modern computer technologies in performing virtual and actual renal tumor surgery. Currently 3D modeling makes it possible to clearly define strategy and tactics of an individual patient treatment.

[UROLOGY LESSONS FOR COLORECTAL SURGEONS].

The anatomical and functional relationship of the pelvic organs is a prerequisite to the development of complications when performing surgical procedures in this anatomical region. Prevention and timely diagnosis of intraoperative injuries of both the urinary system organs and intestine, as well as well-coordinated work of urologist and colorectal surgeon team offer the opportunity to employ optimal tactics for the patient management.

[THE ROLE OF 3D-COMPUTER SIMULATION IN IMPROVING THE STAGHORN NEPHROLITHIASIS TREATMENT RESULTS].

This article presents the experience of applying 3D-computer simulation for treatment planning in patients with coral kidney stones. The impact of the kidney internal structure and the nephrolithiasis stage on the treatment results of the patients with staghorn stones are analyzed on the basis of authors' own experience. They note the usefulness of computer modeling in preoperative planning for improving the treatment results and preventing intraoperative complications.

[3D-TECHNOLOGY AS AN ELEMENT OF PLANNING, EFFECTIVE IMPLEMENTATION AND SURGICAL SIMULATION TRAINING IN STAGHORN NEPHROLITHIASIS MANAGEMENT].

Daily practice of a physician of any specialty is incomplete without an analysis of the data derived from the use of various imaging techniques. Over the past decade, there have been significant changes in the understanding of the clinical anatomy of the patient, which is largely the result of the introduction of modern computer technology in medicine.

[TISSUE-ENGINEERED SUBSTITUTION URETHROPLASTY BASED ON DECELLULARIZED VASCULAR MATRIX AND AUTOLOGOUS CELLS OF THE BUCCAL MUCOSA: THE FIRST EXPERIENCE].

Urethral strictures and anomalies remain a challenging urological problem. Reconstructive plastic surgery has been shown to be the most effective way to treat them. There are two main types of urethroplasty: anastomosis (anastomotic urethroplasty) and expansion of the urethral lumen using of flaps and grafts (substitution urethroplasty).

[FLEXIBLE NEPHSCOPY AND NEPHROLITOEXTRACTION IN A GASEOUS MEDIUM (CO2) IN A PATIENT WITH RESIDUAL CALCULI OF THE RIGHT KIDNEY].

Flexible endoscopy is an integral part of modern endourology. However, the use of flexible endoscopes in a liquid medium predispose to some difficulties and disadvantages of this technique. This article presents a clinical observation of use of a flexible nephroscope for extraction of residual calculi in a gaseous medium (CO2) in a patient with residual calculi of the right kidney.

[TRANSURETHRAL CONTACT URETERAL LITHOTRIPSY IN A GASEOUS (CO2) MEDIUM].

The paper describes for the first time the method of contact ureteral lithotripsy in gaseous (CO2) medium. It presents the results of a comparative study of urolithiasis patients treated with this treatment modality (study group, n=30) and with traditional contact ureteral lithotripsy in liquid medium (control group, n=30). The incidence of retrograde migration of calculus in the kidney in the study group was 0%, while it was 16.

[COMPUTER-ASSISTED SURGERY FOR RENAL TUMORS].

The main objective of this article is to show the role of modern computer technology in performing virtual and real surgical procedures for renal tumors. At the present time, 3D based modeling makes it possible to preoperatively identify individual strategy and tactics of treatment of a patient.
