title: [The selection of the treatment method in stenosis of the pelviureteral segment in nephrolithiasis].
abstract: Ureteropelvic stenoses in nephrolithiasis are suggested to be considered reversible and irreversible depending on the lesions of the upper urinary tracts and the adjacent fat. To ascertain reversibility of the stenosis, use was made of the progesterone test in view of progesterone ability to dilate the ureter. No retention changes in the upper urinary tract in the reversible stenosis can serve an indication to impulse lithotripsy. Large stones and all cases of irreversible stenosis indicate validity of open surgery the scope of which is decided intraoperatively after isolation of the ureteropelvic segment from the periureteral fat and upon the indigo carmine test. In the absence of dysfunctional zone in the segment the patients may be subjected to ureterolysis and pyelolithotomy. If such zone is detected it is possible to make pelvic and proximal ureteral resection, pyeloureterostomy. The technique of the latter surgery in the intrarenal pelvis is detailed.
