Bladder augmentation and continent urinary diversion in boys with posterior urethral valves

Area of Science:

• Pediatric Urology
• Nephrology
• Surgical Innovation

Background:

• Posterior urethral valve (PUV) causes significant bladder and upper urinary tract changes.
• Bladder dysfunction, including hyperreflexia, hypertonia, and poor compliance, necessitates treatment.
• Sphincter incompetence and myogenic failure are common complications of PUV.

Purpose of the Study:

• To review the management of bladder dysfunction secondary to posterior urethral valves.
• To highlight the role and outcomes of bladder augmentation in PUV patients.
• To discuss the long-term implications and potential complications of augmentation cystoplasty.

Main Methods:

• Review of clinical literature on posterior urethral valve management.
• Analysis of treatment strategies for bladder dysfunction in PUV.
• Evaluation of enterocystoplasty as a surgical intervention.

Main Results:

• Bladder augmentation, especially enterocystoplasty, is effective for improving bladder compliance and capacity.
• While associated with complications, enterocystoplasty remains the gold standard for bladder reconstruction.
• Augmentation cystoplasty facilitates spontaneous voiding in most cases, with some requiring clean intermittent catheterization (CIC).

Conclusions:

• Effective management of bladder dysfunction is crucial in posterior urethral valve patients.
• Enterocystoplasty is a vital option for improving bladder function and preparing children for potential kidney transplantation.
• Careful consideration of potential complications is necessary when performing enterocystoplasty.
