    Summary

    Percutaneous nephrostomy effectively relieved upper urinary obstruction in most patients, particularly those with cancer-related blockages. This minimally invasive procedure offers an alternative to surgical interventions for kidney drainage.

    Area of Science:

    • Urology
    • Nephrology
    • Interventional Radiology

    Background:

    • Upper urinary obstruction is a significant clinical challenge.
    • Neoplasms, especially prostate cancer, are a common cause of urinary obstruction.
    • Azotemia and pyonephrosis complicate obstruction management.

    Purpose of the Study:

    • To evaluate the efficacy of percutaneous nephrostomy in relieving upper urinary obstruction.
    • To identify patient populations that benefit most from this procedure.
    • To explore potential extensions of percutaneous nephrostomy techniques.

    Main Methods:

    • Percutaneous nephrostomy was performed in 107 kidneys.
    • Patient data regarding obstruction etiology and outcomes were collected.
    • Success rates and complications were analyzed.

    Main Results:

    • Successful relief of upper urinary obstruction was achieved in 98 out of 107 kidneys (91.6%).
    • Neoplasm, primarily prostate cancer, was the leading cause of obstruction in two-thirds of patients.
    • The procedure was particularly effective for drainage in cases of pyonephrosis and in azotemic patients.

    Conclusions:

    • Percutaneous nephrostomy is a highly successful method for relieving upper urinary obstruction.
    • It serves as a valuable alternative to surgical nephrostomy and prolonged ureteral catheterization.
    • Early experiences with extensions like ureteral stenting and stone dissolution are promising.
