Ureterolitíase em gato: uma abordagem sobre a técnica de ureterotomia microscópica

Abstract

Urolithiasis is a condition where stones (uroliths) are formed, which can be found in the region of the kidneys, urethra, urinary bladder or urethra. It is a disorder that has a multifactorial origin, where crystals precipitate in superconcentrated urine. Uroliths are classified according to the composition of the crystals, with calcium oxalate and struvite being the most common in feline clinical routine. The therapy for these cases varies depending on the composition of the urolith and its location. It involves surgical and non-surgical procedures. Clinical treatment develops alternatives for dissolving the stone, especially in cases of uroliths in the urinary bladder. In cases of ureterolithiasis, where dissolution is difficult and the permanence of the urolith can compromise renal function, surgical techniques are implemented, which aim to remove the ureterolith and ensure the viability of the ureter. Among the surgical approaches for this type of involvement, in the ureter region, the surgical technique of choice in the reported case was microsurgical ureterotomy, due to the viability of the affected ureter segment, as well as the position of the ureterolith.
