This is a technical overview of an INVAMED device within the urology & incontinence management portfolio. Device selection across drainage, stone, and incontinence applications is determined by the treating urologist based on the anatomy, indication, and patient factors. 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
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. 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. Incontinence is addressed with mid-urethral slings such as trans-obturator tape (TOT) and tension-free vaginal tape (TVT), while general urinary drainage relies on Foley and suprapubic catheter systems.
UroFlow Ureteral Stents: Overview
Comprehensive portfolio of polyurethane (PUR) double-J ureteral stents designed to address diverse clinical indications for ureteral drainage, leveraging biocompatible PUR - sometimes treated with phosphorylcholine (PC) - to ensure minimal encrustation, enhanced patient comfort, and safe long-term indwelling (per invamed.com content surfaced via search index; the product page body is client-rendered and returned no text on fetch).
Technical Specifications
Specifications per INVAMED product documentation; confirm current details in the official IFU.
| Attribute | Detail |
|---|---|
| Material | polyurethane (PUR), optional phosphorylcholine (PC) surface treatment |
| Specification | Double-J (DJ) configuration for ureteral drainage; hydrophilic options |
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. A ureteral stent is a thin, flexible tube placed within the ureter to maintain drainage of urine from the kidney to the bladder, often after stone treatment or to relieve obstruction. A guidewire provides a rail over which stents, catheters, and other devices are advanced along the urinary tract, and is fundamental to safe endourological access.
Key Considerations
- Adhering to the intended stent dwell time is emphasized to limit encrustation and related complications.
- Ureteral stent length and diameter (in French) are matched to the patient's anatomy to support drainage and reduce discomfort.
- Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience.
Frequently Asked Questions
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.
When is a nephrostomy used instead of a stent?
The site FAQ notes that percutaneous nephrostomy places a drainage catheter directly into the kidney through the skin to relieve obstruction when ureteral stenting is not possible; the decision is the clinician's.
What is a tipless stone basket?
Per the site FAQ, a stone extraction basket is a wire-mesh device deployed through a ureteroscope, and tipless designs are intended to allow safer engagement of a stone without mucosal trauma.

Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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. Percutaneous nephrostomy is generally reserved for when internal ureteral stenting is not possible, as noted in the site FAQ, and is performed under image guidance. The decision to place a nephrostomy, and the access route, is determined by the treating clinician under image guidance. The use of such sets and devices is determined by the operating clinician according to the planned procedure.
