Urologia e Gestão da Incontinência

A double-J stent maintains ureteral patency in cases of obstruction from stones, tumors, strictures, or post-surgical edema. The J-shaped coils anchor the stent in the renal pelvis and bladder for reliable drainage.

Percutaneous nephrostomy places a drainage catheter directly into the renal collecting system through the skin under imaging guidance. It relieves urinary obstruction when ureteral stenting is not possible.

Stone extraction baskets are wire-mesh devices deployed through a ureteroscope to capture and retrieve ureteral or renal stones. Tipless designs allow safer stone engagement without mucosal trauma.
