Summary
Bilateral same-session flexible ureteroscopy (BS-fURS) is a feasible treatment for bilateral renal stones, offering a single anesthetic session and potentially reduced costs. This approach achieved high stone-free rates, making it suitable for medium-sized stones in high-volume centers.
Area of Science:
- Urology
- Endourology
- Nephrolithiasis Management
Background:
- Staged ureteroscopic procedures are standard for bilateral renal stones.
- Evaluating alternative, potentially more efficient, treatment modalities is crucial.
Purpose of the Study:
- To assess the feasibility of bilateral same-session flexible ureteroscopy (BS-fURS) for treating bilateral renal stones.
- To determine the stone-free rates (SFRs) and complication profile of BS-fURS.
Main Methods:
- Retrospective analysis of 81 patients undergoing BS-fURS between March 2014 and March 2021.
- Utilized four types of flexible ureteroscopes and Holmium laser lithotripsy techniques.
- Assessed stone burden, density, stone composition, operating time, SFRs at 1-3 months via CT, and postoperative complications (Clavien classification).
Main Results:
- Mean stone burden was 17±4 mm, with an average density of 1240 HU.
- Overall SFRs were 81.48% after one procedure and 92.59% after two procedures.
- Low complication rates: Clavien I-II (18.75%), Clavien III (3.12%), with 16.04% experiencing UTIs but no urosepsis.
Conclusions:
- Bilateral same-session flexible ureteroscopy (BS-fURS) is a feasible and effective treatment for bilateral renal stones.
- BS-fURS offers advantages including a single anesthetic session and potentially reduced treatment costs.
- This technique is particularly suitable for medium-sized bilateral renal stones in high-volume urological centers.

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...

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)...

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...

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.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
