Double J Stent Placement or Percutaneous Nephrostomy

Decompression and drainage are often considered when hydronephrosis is accompanied by infection, impaired renal function, uncontrollable pain, or to create conditions for subsequent surgery. The choice between a double-J stent or nephrostomy depends on the site of obstruction, anatomy and instrument accessibility, as well as coagulation and systemic conditions, as comprehensively assessed by a specialist.
