RESUMO
The article presents the results of 44 laparoscopic ureterolithotomies performed for large stones in upper and middle third of the ureter. Patients' age ranged from 35 to 82 years. The different types of drainage of the urinary tract depending on the characteristics of surgical treatment (retro- or transperitoneal ureterolithotomy) were used. The effectiveness was evaluated according to the results of plain urography, ultrasound, and multi-layer spiral CT. The results showed that the preferred method of urinary tract drainage is a preoperative deployment of ureteral catheter-stent. However, in the case of impossibility of such procedure, preoperative deployment of ureteral catheter with subsequent intraoperative replacing it on catheter-stent is permissible. With retroperitoneal approach, tubeless ureterolithotomy is feasible in the absence of the ipsilateral kidney stones, residual ureteral stones and pronounced changes in the area of finding the stones.
