Extensive surgery on the trigone for complete ureteral duplication does not cause incontinence or voiding problems

Area of Science:

• Pediatric Urology
• Nephrology
• Surgical Innovation

Background:

• Kidney and ureteral duplication is a common congenital anomaly.
• Surgical intervention is often necessary to manage complications.
• The impact of extensive trigonal surgery on long-term bladder function requires evaluation.

Purpose of the Study:

• To assess the safety and long-term effects of extensive trigonal surgery in children with duplicated kidneys.
• To determine if trigonal surgery influences subsequent bladder and urethral function.
• To investigate the relationship between trigonal surgery and voiding dysfunction.

Main Methods:

• A retrospective study of 201 children with surgically treated kidney and ureteral duplication.
• 145 patients were followed for a mean of 5 years, with detailed assessment of voiding habits, continence, and renal function.
• Urodynamic evaluation was performed in children with recurrent urinary tract infections or dysfunctional voiding.

Main Results:

• No significant increase in bladder dysfunction was observed following extensive trigonal surgery.
• Most cases of vesicoureteral reflux resolved within a year post-surgery.
• A small number of patients experienced voiding issues, but these were not directly linked to the extent of trigonal surgery.

Conclusions:

• Extensive trigonal surgery for duplicated kidneys is not associated with adverse long-term bladder or urethral dysfunction.
• Pre-existing trigonal abnormalities due to ureteroceles do not predispose to later bladder dysfunction.
• The findings support the safety of current surgical approaches for managing kidney and ureteral duplication.
