Summary
Laparoscopic totally intracorporeal ileal ureter replacement (LIUR) is a feasible and reproducible surgical technique. This multicenter study demonstrates its effectiveness in restoring long ureteral defects with a good follow-up.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Reconstructive Surgery
Background:
- Ureteral defects pose significant reconstructive challenges.
- Traditional open surgical methods can be associated with considerable morbidity.
Purpose of the Study:
- To evaluate the feasibility and reproducibility of laparoscopic totally intracorporeal ileal ureter replacement (LIUR).
- To present a multicenter patient cohort with long-term follow-up data.
Main Methods:
- Retrospective analysis of patient records undergoing ureteral replacement.
- Follow-up assessments included chemical profiles, urine cultures, and imaging (ultrasonography, excretory urography, cystography, or isotopic renography).
Main Results:
- Forty patients underwent LIUR (right, left, or bilateral).
- Mean procedure time was 335 minutes; mean blood loss was 221 mL.
- Low complication rates (3 intraoperative, 3 Clavien III postoperative); mean hospital stay 13.5 days.
Conclusions:
- LIUR is a feasible and reproducible surgical option.
- It effectively restores function in patients with long ureteral defects.

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...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

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...
