The urological anomalies associated with anorectal malformations

Abstract EN

Background : Urological anomalies are frequently associated with anorectal malformations which are a common source of significant morbidity.

Objective : Is to evaluate the incidence and nature of the urological anomalies with patients of anorectal malformations (ARM).

Patients & methods : The data from 95 patients with ARM were studied from January 2009 to January 2012 in this cross-sectional study.

All patients underwent sonography of urinary tract.

Voiding cystourethrogram (VCUG) was done in patient with abnormal sonography & to all male patients with ARM who underwent colostomy.

Other imaging studies were done in selected cases.

Results : Males significantly constitute the majority 64 / 95 (67.4 %) of ARM cases, while females constitute 31 / 95 (32.6 %) of patients, male to female ratio is 2:1.

High type anomaly significantly constitutes the majority of the patients 79 / 95 (83.2 %) in both genders.

Urologic malformations were found in 24 / 95 (25.3 %) patients with a significantly high frequency in males 21 / 64 (32.8 %) while 3 of them were females 3 / 31 (9.7 %).

Urological anomalies occur more with high type ARM (27 %) versus (12%) in low type ARM.

Vesicoureteral reflux (VUR), renal agenesis, and hydronephrosis were the most common urologic anomalies respectively.

Conclusions : The high incidence of associated urogenital anomalies necessitates a careful investigation of all patients with ARM and continued long term follow up of these patients is mandatory to avoid deterioration of renal function in future.
