The Nephrostomy Devices Market in 2026 is benefiting from significant advances in imaging guidance technology that are improving the safety and technical success rate of percutaneous kidney access for both nephrostomy drainage and percutaneous nephrolithotomy by enabling more precise needle targeting, better anatomical visualization during the technically demanding access steps, and more confident calyceal anatomy assessment that guides optimal access point selection. The integration of real-time ultrasound imaging with fluoroscopic guidance in combined ultrasound-fluoroscopy access techniques provides complementary information from each modality, with ultrasound enabling soft tissue visualization including renal parenchyma thickness, adjacent organ position, and needle-to-parenchyma relationship during initial renal puncture, while fluoroscopy provides collecting system anatomy and needle position within the pelvicalyceal system after collecting system entry is established. Cone-beam CT guidance for percutaneous kidney access at hybrid operating room facilities provides three-dimensional anatomical planning with immediate needle position verification in complex cases including anatomically abnormal kidneys, horseshoe kidney anatomy, and prior surgical anatomical distortion where standard ultrasound-fluoroscopy guidance may not provide adequate anatomical detail for safe access planning. The development of needle tracking systems that display real-time needle position relative to target calyces on three-dimensional reconstructed renal imaging using electromagnetic sensor integration into access needles is creating image-fused guidance that reduces the operator experience-dependence of complex access point targeting.

Fusion imaging platforms that register preoperative CT imaging of the kidney with real-time ultrasound imaging during the percutaneous access procedure create an overlay visualization showing the three-dimensional CT-derived collecting system anatomy superimposed on the ultrasound image plane, enabling operators to precisely plan needle trajectories toward specific target calyces while visualizing soft tissue anatomy in real time through ultrasound, combining the detailed anatomical planning capability of CT with the real-time procedural guidance of ultrasound that neither modality alone provides. Artificial intelligence-powered real-time calyceal anatomy identification systems that automatically segment and label renal calyceal anatomy from intraoperative fluoroscopic images or cone-beam CT reconstructions are beginning to provide automated anatomical annotation that assists less experienced operators in identifying optimal access calyces for specific PCNL stone locations, with AI guidance reducing the learning curve for complex access planning that currently requires extensive operator experience to develop. The development of simulation training platforms for percutaneous nephrostomy and PCNL access using haptic-feedback needle insertion simulators and anatomically accurate kidney phantoms is enabling training program development that allows operators to develop and assess percutaneous access skills before performing cases on patients, addressing the patient safety concern that percutaneous access training has traditionally required in the operating room on actual patients. As imaging guidance technology continues advancing and simulation training programs improve the consistency of operator skill development across different training programs, the clinical outcomes for percutaneous kidney access procedures are expected to improve across the full spectrum of operator experience levels and practice settings.

Do you think AI-assisted calyceal anatomy identification and needle guidance will substantially reduce the operator experience required for successful complex PCNL access, enabling broader adoption of percutaneous stone treatment at community urology practices rather than concentrating these procedures at specialized endourology centers?

FAQ

• What are the key anatomical considerations in selecting the optimal calyx for percutaneous nephrolithotomy access and how does the stone location within the kidney influence access planning? Optimal PCNL calyceal access selection balances several anatomical considerations including the infundibulopelvic angle between the target calyx and the ureteropelvic junction that determines nephroscope angulation for stone access within the collecting system, calyceal orientation in three-dimensional space relative to the skin access point that must allow a straight working sheath trajectory without excessive angulation that limits nephroscope maneuverability, parenchymal thickness over the target calyx that determines access bleeding risk with thinner posterior lower pole parenchyma generally preferred over thick anterior or upper pole parenchyma, proximity to adjacent organs including colon, spleen, and liver that creates injury risk with specific access trajectories, and stone location within the collecting system with upper pole access required for upper pole stones, middle calyces for pelvis and multiple calyceal stones, and posterior lower pole access preferred for lower pole stones to achieve favorable nephroscope angulation.
• How does the success rate and complication profile of percutaneous nephrostomy vary between interventional radiology and urology operators and what factors account for performance differences? Comparative studies of percutaneous nephrostomy outcomes between interventional radiology and urology operators show broadly similar overall technical success rates averaging ninety-five percent or above for both specialty groups in experienced hands, with performance differences observed in specific technical approaches where IR operators more commonly use fluoroscopic guidance with ultrasound assist while urologists more commonly use combined ultrasound-fluoroscopy or pure ultrasound access, access tract size where urologists more commonly perform large-caliber PCNL access while IR typically places smaller drainage catheters, and complication profile differences reflecting the different case selection and procedure objectives between specialties rather than inherent operator skill differences, with operator experience volume within each specialty being the primary determinant of outcomes within each training background.
