Introduction: The leading cause of chronic renal failure in newborns, which occurs soon after birth is obstructive uropathies. Objectives: To prove the effectiveness of nephroamniotic shunting based on the evaluation of perinatal outcomes of this procedure, as well as a comparative analysis of the use of the stent manufactured by “Cook” (Ireland), 3.0 Fr/100 mm and the stent “SDE–MED”, 3.0 Fr/50 mm with the original shape of pigtails. Methods: After checking the safety of the stent “SDE-MED”, 3.0 Fr/50 mm developed by FGBU Mother and Child Care Research Institute with the original shape of pigtails in an animal experiment, the stent was used in clinical practice for intrauterine shunting in cases of unilateral or bilateral hydronephrosis of grade III to IV and posterior urethral valve disorder. In the final part of the study, a comparison of the outcomes of nephroamniotic shunting using two different stents was made. Results: The “SDE–MED” 3.0 Fr/50 mm stent provided more effective fixation in the fetal kidney cavity system in comparison to the stent manufactured by “Cook” (Ireland) 3.0 Fr/100 mm. Conclusion: Intrauterine shunting surgery of the upper urinary tract is a pathogenetically justified method of treating urinary tract obstructions and can be used to correct all types of fetal renal obstructions.
