RISK OF OCCURRENCE AND WAYS TO IMPROVE THE TREATMENT OF UROLITHIASIS IN PATIENTS WITH A SINGLE KIDNEY.

Objective: The aim: To summarize the state of the problem of urolithiasis in patients with a single kidney and consider current views on improving its treatment based on the analysis of world literature.

Patients And Methods: Materials and methods: The study conducted a thorough analysis of modern scientific literature sources in the international scientometric database, which highlighted the development of urolithiasis in patients with a single kidney and the peculiarities of its treatment. The main ways to improve treatment are identified.

Performance status and quality of life after reconstructions of buccal mucosal and retromolar trigone defects by skin and fascial flaps in oncologycal patients.

Objective: The aim: of the study is to compare surgical and functional results as well as quality of life after use of skin flaps - platysma myocutaneus flap, supraclavicular artery flap and fascial flaps - temporoparietal fascial flap, buccal fat pad for plastic closure of the buccal and retromolar trigone mucous surgical defects in cancer patients.

Patients And Methods: Material and methods: A retrospective comparative analysis of the results of surgical treatment of buccal and retromolar trigone mucosal cancer in 56 patients operated from 2009 to 2014 was made. The patients were divided into two groups: the first included 26 patients, with reconstruction of fascial flaps, the second group included 30 patients, with reconstruction of postoperative defects with skin flaps.

[Mathematical model application in the design of methods for reconstructive surgery of the stomach].

Advantages and faults of reconstructive operations after stomach resection according to Billroth-II were analyzed using principles of mathematical modelling on entire electroconductive mediums. Optimal method of the longitudinal axis of small intestine placement under an acute angle to the lesser curvature of stomach promotes the pressure reduction in the region of stomach and intestine junction prevents the hydrodynamic shock appearance, provides a smooth transference of the stomach contents while its emptying.
