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.
