Catheters are widely used in urological surgeries, including diagnosis, treatment, and postoperative care. Different types of catheters each have their specific functions and advantages, providing crucial support for successful surgery and postoperative recovery. This article will explore the diverse applications of catheters in urological surgeries.

Types of Commonly Used Catheters in Urinary Surgery

1. Ureteral Stent Catheter

Function: Used to maintain ureteral patency and prevent urinary tract obstruction caused by postoperative edema or residual stones.

Application: Widely used in percutaneous nephrolithotomy (PCNL) and ureteroscopic lithotripsy (URS) to ensure postoperative urinary flow patency.

2. Bladder Catheter

Function: Used for postoperative bladder drainage and urine output monitoring to prevent urinary retention and infection.

Application: Particularly suitable for patients after prostate surgery and bladder tumor resection.

3. Nephrostomy Catheter

Function: Used in percutaneous nephrostomy (PCN) to provide a direct kidney drainage pathway and relieve kidney pressure.

Application: Suitable for patients with hydronephrosis, kidney infection, and severe urinary tract obstruction.

Double J-type Stent: Designed with highly elastic materials, increasing stability and comfort within the ureter and reducing the risk of displacement and infection.

Antibacterial Coating Technology: Applying an antibacterial coating to the catheter surface reduces bacterial adhesion and the risk of infection, especially in cases of long-term indwelling.

Advantages of Catheter Application

Reduced Postoperative Complications: The use of catheters effectively prevents and manages postoperative complications such as urinary tract obstruction and infection.
