RESUMO
UNLABELLED: Ileal conduit as a form supravesical derivaton, is still one of most popular method of urinary diversion, in daily urological practice. Bearing in mind this fact, this type of diversion, rightfully so, is also called the "gold standard" in the derivation of urine. Considering the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect that, in time, this type of diversion lead to some degree of renal insufficiency. Some authors, this effect on renal function, attribute to specific type of ureterointestinal anastomosis during formation of ileal conduit. A very important part of the surgical technique of creating ileal conduit is precisely a step of implantation ureters into the intestinal segment. The ultimate goal is to enable a more natural way of evacuation of urine from the upper urinary tract in terms of maintaining the quality of renal function. Numerous authors describes a quite number of techniques of ureteral implantation into the intestinal segment (Wallace A, Wallace B, Nesbit-Bricker, Le Duc ...). Each of these techniques has its own strengths and weaknesses, and the decision witch technique will be applied is still in the hand of urologist--operator, individually.Bearing in mind the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect that the renal function over the time will start to show signs of incipient or advanced failure. OBJECTIVE: To determine the most appropriate type ureterointestinal anastomosis in forming ileal conduit, as a form of supravesical urinary diversion, to ensure adequate renal function postoperatively as an important parameter of quality of life. METHODS AND PATIENTS: This is a retrospective study, which covered a population of 193 patients treated at the Department of Urology, Clinical Center of Serbia, who underwent creation of ileal conduit as a form of urinary diversion. The study was conducted 2007-2011. Postoperative follow-up lasts up to 48 months. The assess of the level of renal insufficiency were analyzed by monitoring parameters which determine the degree of anemia, and biochemical parameters of renal function. We have investigated three techniques of insertion of the ureters into the ileal conduit, which are used in the daily practice (Wallace A, Wallace B, Nesbit-Bricker). CONCLUSION: Kidney failure occurs equally often in all patients who underwent urinary diversion by ileal conduit, ignoring the type of insertion of the ureters to the intestinal segment.
