Summary
Regular bladder washout did not significantly reduce stone formation in children with enterocystoplasty. This study compared stone incidence in patients with enterocystoplasty and clean intermittent self-catheterisation (CISC).
Area of Science:
- Pediatric Urology
- Surgical Innovation
- Nephrology
Background:
- Enterocystoplasty is a surgical procedure to augment or reconstruct the bladder.
- Stone formation is a known complication following enterocystoplasty.
- The role of regular bladder washout in preventing stones is unclear.
Purpose of the Study:
- To investigate the incidence of bladder stone formation in children who underwent enterocystoplasty.
- To evaluate the effectiveness of regular bladder washout in mitigating stone formation.
- To compare stone incidence between different surgical techniques and clean intermittent self-catheterisation (CISC).
Main Methods:
- Prospective cohort study of 30 children with enterocystoplasty and continent diversion (1988-1995).
- Comparison with 30 children undergoing augmentation alone and 30 children performing CISC.
- All patients instructed in weekly bladder washout; frequency increased with mucus production.
Main Results:
- Bladder stones developed in 5 (17%) children with continent diversions (mean 35 months post-op).
- Stones occurred in 2 (7%) children with augmentation alone.
- No stones were observed in children performing CISC on their native bladders.
Conclusions:
- A regimen of regular bladder washout did not significantly decrease stone formation in children with enterocystoplasty.
- The incidence of stone formation in this cohort was comparable to previously published data.
- Clean intermittent self-catheterisation (CISC) on native bladders showed no stone formation.

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

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...

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.

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...

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...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
