Limited surgical intervention in the prune belly syndrome

Area of Science:

• Pediatric Surgery
• Urology
• Developmental Biology

Background:

• Prune belly syndrome (PBS) is a rare congenital disorder characterized by abdominal muscle deficiency, urinary tract abnormalities, and cryptorchidism.
• Management of PBS is complex and often involves surgical intervention, but the optimal approach remains debated.

Purpose of the Study:

• To evaluate the outcomes of surgical and non-surgical management in a cohort of male patients with prune belly syndrome.
• To identify factors influencing prognosis and guide treatment decisions in PBS.

Main Methods:

• Retrospective review of 16 male patients diagnosed with prune belly syndrome.
• Analysis of surgical interventions, including loop cutaneous ureterostomies and management of urethral obstruction.
• Assessment of renal function and survival rates.

Main Results:

• Half of the 16 patients experienced favorable outcomes without any surgical treatment.
• Two patients underwent unnecessary loop cutaneous ureterostomies, deemed inappropriate.
• Urethral obstruction was identified in two boys, and four neonates died due to severe renal dysplasia.
• Dilated distal ureters, while common, generally function adequately and rarely require complex reconstructive surgery.

Conclusions:

• A significant proportion of prune belly syndrome patients may not require surgical intervention, suggesting a more conservative approach is warranted.
• Unnecessary surgical procedures should be avoided, and treatment should be tailored to individual patient needs, particularly addressing urethral obstruction and renal dysplasia.
• The natural course of ureteral dilation in PBS often allows for adequate function, minimizing the need for extensive ureteral reconstruction.
