Ultrasonographic evaluation of bladder function restoration after “sutureless” cystotomic wound closure use in cats

The purpose of reseaech is to study the features of wound scar formation with “sutureless” and traditional (double-row suture) methods of closing a cystotomy wound, as well as to identify functional deviations of the operated organ through ultrasonographic studies in the early postoperative period. The study was carried out as part of the work of the Educational and Scientific Center of the Faculty of Veterinary Medicine of the Altai State Agrarian University. Surgical interventions and ultrasonographic studies were performed at the Department of Morphology, Surgery and Obstetrics in cats of British, Persian and outbred breeds (n = 19) admitted for clinical visits. In 8 animals, a “sutureless” connection of the edges of the surgical wound of the bladder was used, and in 11 cats, according to clinical indications, the traditional method of suturing was used. To determine the functionality of the operated bladder in the early postoperative period, all animals used in the experiment underwent ultrasound diagnostics on an HTI PU-2200 Vet apparatus with a 7Mz linear sensor. The use of an adhesive suture ensures correct reposition of the dissected layers of the bladder without entrapment of the mucous membrane, respectively, its subsequent necrobiosis, which ensures high biological tightness and rapid fusion of the edges of the surgical wound, resulting in the formation of a full-fledged elastic wound scar. The method of “sutureless” connection of the edges of a cystotomy wound cannot be used for degenerative changes in the tissues of the bladder. The use of a traditional double-row suture reduces the bladder cavity due to the massive tissue shaft that forms when the cystotomy wound is closed, leading to the formation of a massive postoperative scar and a decrease in the contractility of the operated organ. The choice of method for closing a surgical wound of the bladder depends on the morphofunctional state of the organ, the clinical status of the patient and the severity of the disease at the time of surgery.
