Summary
This study introduces a new robotic system for treating kidney stones using ureteroscopy. The novel flexible robotic platform demonstrated promising initial results for remote laser lithotripsy.
Area of Science:
- Urology
- Robotic Surgery
- Endourology
Background:
- Renal calculi (kidney stones) pose a significant clinical challenge.
- Minimally invasive techniques are preferred for stone management.
- Current ureteroscopic procedures require direct surgeon manipulation.
Purpose of the Study:
- To evaluate the initial clinical experience of a novel flexible robotic system for remote ureterorenoscopy and laser lithotripsy.
- To assess the feasibility and safety of robotic-assisted treatment for intrarenal calculi.
Main Methods:
- Eighteen patients with renal calculi (5-15 mm) underwent flexible robotic ureteroscopy.
- A novel flexible robotic catheter system was introduced remotely.
- Intrarenal maneuvers, including stone fragmentation, were performed from a robotic console.
Main Results:
- All procedures were technically successful, with no conversion to manual ureteroscopy.
- High satisfaction scores were reported for robotic control, stability, and fragmentation ease.
- Complete stone clearance rates were 56% at 2 months and 89% at 3 months, with stable renal function.
Conclusions:
- A novel flexible robotic platform enables retrograde ureteroscopic treatment for intrarenal calculi.
- Initial clinical experience with this robotic system is encouraging for kidney stone management.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
01:22Imaging Studies V: Intravenous Urography and Retrograde Pyelography
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

01:28Urinary Tract Calculi I: Introduction
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...
01:30Urinary Tract Calculi III: Medical Management
The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
