METHOD FOR END-TO-END ANASTOMOTIC URETHRA REPAIR IN SURGICAL TREATMENT OF BULBOSE URETHRA STRICTURE Russian patent published in 2025 - IPC A61B17/00 A61K33/18 A61K49/08 A61P43/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to urology. 5 ml of 0.5% aqueous solution of indocyanine green – ICG is introduced into a glans penis at distance of 1.0 cm from an external opening of the urethra. Fluorescence intensity is visually assessed when illuminating the spongy body – SB using a light source with wavelength of 0.75 to 1.4 mcm. SB fibrosis is detected in the area with fluorescence intensity less than 50% of the fluorescence intensity of normal SB tissue. Bulbous urethra is exposed in the area of the revealed fibrosis of the SB. Bulbous urethra stricture is detected in the area with fluorescence intensity less than 50% of the fluorescence intensity of normal urethral tissue. Thereafter, the SB is resected within the detected fibrosis zone and the bulbous urethra is resected within the detected stricture zone. Further, the urethral edges are spatulated with a longitudinal incision of each of them throughout 0.5-1.0 cm, and an anastomosis is applied between the ends of the urethra. In addition, after resection of SB and bulbous urethra, complete excision of SB fibrosis and bulbous urethra stricture is controlled by visual assessment of fluorescence intensity in SB and bulbous urethra edges formed after their resection. If observing the areas with fluorescence intensity less than 50% of the fluorescence intensity of the normal tissue of the SB and bulbous urethra, additional excision of SB fibrosis zones and/or bulbous urethra stricture is performed. When forming the anastomosis, a single-row suture is applied along the dorsal surface of the bulbous urethra and a double-row suture is applied along the ventral surface of the bulbous urethra.

EFFECT: method enables providing an adequate healing process in the area of the urethral anastomosis, which reduces the risk of postoperative complications, recurrence of the disease and the probability of recurrent surgical interventions.
