Summary
Endoscopic trigonoplasty II (ET II) is an anti-reflux surgery with a success rate inferior to open or laparoscopic methods. Researchers do not recommend ET II for treating vesicoureteral reflux due to its lower efficacy.
Area of Science:
- Urology
- Surgical Techniques
Context:
- Vesicoureteral reflux (VUR) is a condition where urine flows backward from the bladder to the ureters.
- Traditional anti-reflux surgeries include open and laparoscopic ureteral reimplantation.
Purpose:
- To evaluate the technique and outcomes of endoscopic trigonoplasty II (ET II), a transvesicostomy transurethral anti-reflux surgery.
- To discuss the usefulness of ET II in treating vesicoureteral reflux.
Summary:
- Fifteen female patients underwent ET II for VUR, involving bladder wall incision and ureteral reimplantation through a transurethral approach.
- The surgery achieved an 86% reflux cessation rate at 12 months, but complications included ureteral injury and fistula formation.
- The overall efficacy was lower than established open or laparoscopic anti-reflux procedures.
Impact:
- Endoscopic trigonoplasty II (ET II) demonstrated a lower success rate compared to traditional open and laparoscopic anti-reflux surgeries.
- The study advises against using ET II for vesicoureteral reflux management.
- Complications associated with ET II highlight the need for caution and further research into minimally invasive VUR treatments.

Urinary Tract Calculi VI: Surgical 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...
Imaging 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. Intravenous Urography (IVU)Intravenous...
Urologic Endoscopic Procedure: Cystoscopic Examination
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...
Urinary 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)...
