Ureteral double- J stent is usually inserted by retrograde approach for the treatment of obstructed upper urinary tract. The antegrade approach, can a suitable alternative in certain situations without the need for general or spinal anesthesia. The present study demonstrates the indications, success rate, and complications of this approach in the treatment of malignant obstructive uropathy.

Data of consecutive patients in whom antegrade ureteral stent¬ing was performed between January 2013 and February 2020 were retrospectively analysed using patient records and radiology reports. A total of 174 patients (sexe ratio = 0.51, age range 9-91 years; mean age, 54 years) were included in the study.

Ureteral obstruction was caused by bladder cancer (n=92), uterin cancer (n=31), prostate cancer (n=28), colorectal cancer (n= 15) and retroperitoneal tumor (n= 8) (Table 1).

Inclusion Criteria:

• malignant uropathy obstruction

Exclusion Criteria:

• benign uropathy obstruction

A total of 174 patients (sexe ratio = 0.51, age range 9-91 years; mean age, 54 years) were included in the study.
