Urinary Tract Calculi VI: Surgical Management

75
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

718
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...

Imaging Studies VI: Voiding Cystourethrography and Cystography

273
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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

337
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 III: Medical Management

57
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)...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Area of Science:

  • Pediatric Urology
  • Minimally Invasive Surgery

Background:

  • Augmented bladders, often resulting from bladder exstrophy repair, have a high incidence and recurrence rate of bladder stones.
  • Recurrent open cystolithotomy is challenging and less preferred due to scarred tissues from previous surgeries.

Purpose of the Study:

  • To evaluate the efficacy and safety of percutaneous cystolithotomy (PCCL) for bladder stone removal in children with augmented bladders.
  • To adapt an established adult procedure for a pediatric population with complex bladder reconstructions.

Main Methods:

  • PCCL was performed in three pediatric patients with augmented bladders.
  • A suprapubic needle track was created under cystoscopic guidance.
  • Bladder stones were removed using graspers through a dilated track and laparoscopic cannula.

Main Results:

  • PCCL demonstrated a good outcome in the augmented bladders.
  • No adverse effects on continence or bladder capacity were observed post-procedure.
  • Skin tissue patches were noted in native bladders during cystoscopy.

Conclusions:

  • PCCL is a viable and effective minimally invasive option for bladder stones in augmented bladders in children.
  • High stone recurrence may be linked to keratin from dermal tissue within the augmented bladder.
  • Further investigation into techniques like shaving or fulguration during reconstruction may reduce stone formation incidence.
