Insights

Intravesical detrusorrhaphy, a modified ureteral reimplantation, effectively treats vesicoureteral reflux (VUR) and obstructive megaureter (OM). This technique shows high success rates and avoids postoperative urinary retention in bilateral cases.

Area of Science:

  • Pediatric Urology
  • Surgical Techniques
  • Urology

Background:

  • Vesicoureteral reflux (VUR) and obstructive megaureter (OM) are common pediatric urological conditions.
  • Traditional ureteral reimplantation techniques can have associated complications.

Purpose of the Study:

  • To describe the surgical procedure of intravesical detrusorrhaphy.
  • To report initial clinical experience with this modified ureteral reimplantation technique.

Main Methods:

  • An open intravesical approach was used for intravesical detrusorrhaphy.
  • The technique involves creating a submucosal tunnel by repairing the detrusor underneath the mobilized ureter.
  • The ureteral orifice is anastomosed to its orthotopic position.

Main Results:

  • The study included 55 children with VUR and 13 with OM.
  • Success rates for VUR resolution were 91.1% (68/72 ureters).
  • Improvement rates for OM were 84.6% (11/13 patients, 12/14 ureters).
  • No postoperative urinary retention occurred in bilateral cases.

Conclusions:

  • Intravesical detrusorrhaphy is a safe and effective modified ureteral reimplantation technique.
  • It successfully recreates the neo-ureteric orifice in the orthotopic position.
  • The procedure is well-tolerated, with no reported urinary retention in bilateral procedures.

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.

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...

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...

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...
