This is a technical overview of an INVAMED device within the urology & incontinence management portfolio. This clinical area covers urinary drainage, stone management, and the treatment of incontinence, using devices that maintain or restore the flow of urine and support the management of stones. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Urinary Drainage, Stone Management, and Incontinence
Ureteral drainage is commonly achieved with double-J (DJ) ureteral stents, while percutaneous nephrostomy places a drainage catheter directly into the renal collecting system through the skin under imaging guidance when ureteral stenting is not possible. According to invamed.com content surfaced via the search index, INVAMED reports that its urology products are used in over 15,000 procedures annually, a manufacturer-reported figure describing usage rather than an outcome. Stone management devices include stone extraction baskets, which the site FAQ describes as wire-mesh devices deployed through a ureteroscope to capture ureteral or renal stones, with tipless designs intended to allow safer engagement without mucosal trauma.
Bionovus Percutaneous Nephrostomy Catheter (Pigtail): Overview
Advanced pigtail-style percutaneous nephrostomy catheter intended for temporary external drainage in upper ureteral and renal obstructions, helping alleviate pressure buildup, maintain renal function, and reduce patient discomfort (per invamed.com content surfaced via search index).
Technical Specifications

How It Works and Where It Fits
INVAMED's urology portfolio is organized by function, spanning ureteral stents, percutaneous nephrostomy and nephrectomy sets, guidewires, and injection needles. Each device is intended for use by trained clinicians under appropriate guidance and per the IFU. Double-J stents are typically placed cystoscopically over a guidewire, with the two curled ends providing retention at the kidney and bladder. Percutaneous nephrostomy places a drainage catheter directly into the renal collecting system through the skin under imaging guidance, relieving obstruction when ureteral stenting is not possible.
Key Considerations
- Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience.
- All INVAMED urology devices are intended for use by trained clinicians under appropriate guidance and in accordance with the IFU.
- Manufacturer figures such as the reported over-15,000-procedures-annually usage statistic describe activity rather than guaranteed individual outcomes.
Frequently Asked Questions
How long can a ureteral stent stay in place?
Ureteral stents have a defined maximum dwell time stated in the device documentation to limit encrustation and other risks, and the exact timing of removal or exchange is set by the urologist.
How many procedures use INVAMED urology products?
According to invamed.com content surfaced via the search index, INVAMED reports that its urology products are used in over 15,000 procedures annually, a manufacturer-reported usage figure.
What are UroFlow stents made of?
INVAMED describes UroFlow Ureteral Stents as polyurethane (PUR) with an optional phosphorylcholine (PC) surface treatment and hydrophilic options, in a double-J configuration for ureteral drainage.

Clinical and Technical Context
Stone management devices include stone extraction baskets, which the site FAQ describes as wire-mesh devices deployed through a ureteroscope to capture ureteral or renal stones, with tipless designs intended to allow safer engagement without mucosal trauma. INVAMED's Zebra Guidewire for Urological Procedures is offered to support these endourological access steps. INVAMED offers the Bionovus Nephrectomy Set and the FlexInject Flexible Injection Needle within its urology portfolio. The use of such sets and devices is determined by the operating clinician according to the planned procedure.
