Urogenital anomalies associated with anorectal malformations

Abstract

Objective: Urogenital anomalies are frequently associated with anorectal malformations which are a common source of significant morbidity. The aim of this study was to evaluate the incidence and nature of associated urogenital anomalies in patients with Anorectal Malformations (ARM). Methodology: Documents of 104 patients with ARM were studied from 2003 to 2005. All patients underwent sonography of urinary tract and Lumbosacral radiography. Other imaging studies were done in selected cases and voiding cystourethrography (VCUG) performed in 62 patients. Results: Urologic malformations were found in 44 patients (42.3%) without sexual preponderance (p>0.05). Genital anomalies were detected in 16 cases (15.5%) with a significantly high frequency in mates (p<0.05). The incidence of associated urogenital anomalies was significantly higher in "high" form of anomaly than those with "low" form (p<0.05). Vesicoureteral reflux (VUR), hydronephrosis, and renal agenesis were the most common urologic anomalies respectively. Cryptorchidism and hypospadiasis were the most frequent genital anomalies. Sacrospinal anomalies were detected in 22% of patients. Conclusion: The high incidence of associated urogenital anomalies necessitates a careful investigation of all patients with ARM. VCUG is essential even with normal sonographic findings.
