This article explains, in educational terms, nephrectomy set — how the technology works and where it fits. 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
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. 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. Device selection across drainage, stone, and incontinence applications is determined by the treating urologist based on the anatomy, indication, and patient factors.
Nephrectomy and Injection Devices
Procedural sets and accessory devices support renal and urological interventions by bundling the components needed for a given approach. A flexible injection needle allows targeted delivery of an agent during endoscopic procedures where injection is required. 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.
Design and Technical Notes
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. Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience. Adhering to the intended stent dwell time is emphasized to limit encrustation and related complications.
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
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.
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.
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.

Clinical and Technical Context
The dwell time and choice of stent are determined by the urologist according to the clinical situation. Ureteral stent length and diameter (in French) are matched to the patient's anatomy to support drainage and reduce discomfort. Baskets are used within a broader endourological approach that may also involve laser or other lithotripsy as determined by the urologist. Stent length, diameter (in French), and coating are selected by the urologist based on the patient's anatomy and indication. INVAMED's Zebra Guidewire for Urological Procedures is offered to support these endourological access steps. Guidewire selection is made by the operator based on the anatomy and the devices being delivered. Material and surface treatments, such as polyurethane with a phosphorylcholine or hydrophilic option, can influence insertion and the indwelling experience. 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.
