Malecot Catheter: A Malecot catheter is a type of indwelling catheter that has multiple outward-facing retention wings or flanges near its tip. These wings help to anchor the catheter in place within the urinary tract or other body cavities, preventing its accidental dislodgement. Malecot catheter is designed to be used for temporary drainage in the wake of a medical procedure or medical issue such as incontinence or kidney stones.
Nephrostomy Catheter: A nephrostomy catheter is specifically designed for drainage of urine from the kidney. It is inserted through a small incision in the back or side, guided into the renal pelvis (the central collecting area of the kidney), and secured in place. The catheter provides an external drainage route for urine when the normal urinary flow is obstructed or needs to be diverted.
Rubber Material: The Malecot nephrostomy catheter you mentioned is made of rubber. Historically, rubber was a commonly used material for catheters, but nowadays, silicone and other biocompatible materials have largely replaced rubber due to concerns about potential allergic reactions and latex sensitivities.
The use of a Malecot nephrostomy catheter requires specialized medical knowledge and expertise. The catheter insertion and management are typically performed by urologists or interventional radiologists who are trained in nephrostomy procedures.

What is a Malecot catheter?
The Malecot (Stamey) catheter has been routinely used as a self-retaining tube in the drainage of different body fluids, e.g. urine, bile, pus. It was originally described for use in suprapubic cystostomy, which required the use of a needle with the catheter.
How do you insert a Malecot catheter?
Place the stylet inside the Malecot catheter and secure its position with the luer lock to straighten the malecot flower wings. Pass the Malecot end of the catheter over the external end of the guide wire, gradually advance the Malecot flower end well into the collecting system. Confirm the position fluroscopically.
How do you remove a Malecot catheter?
Gently pulling the balloon catheter (star) allowed reversal of the Malecot catheter tip (arrow- head), facilitating successful retrieval and the insertion of another 10-Fr Malecot catheter via the in- ferior calyx of the kidney (arrow).
