Urological problems or fecal continence during long-term follow-up of patients with anorectal malformation.

introductionAnorectal malformations comprise a wide spectrum of diseases. The main concerns for the surgeon in correcting these anomalies are bowel control, urinary control, and sexual function. The aim of this study was to evaluate fecal continence together with additional urinary anomalies in patients with anorectal malformations (ARM) and determine which of them is more troublesome for life quality in long-term follow-up. MATERIALS AND

methodsA total of 93 cases followed up and treated at our clinic between 1983 and 2009 were evaluated for urinary pathologies, fecal continence, and their quality of life (QOL). Patients were classified according to the international system (Krickenbeck), and were evaluated on the basis of voluntary bowel movement, constipation, and fecal soiling. They were also classified as good, fair, and poor regarding fecal continence. The urinary system pathologies, the medical and surgical treatments received, and the pediatric nephrology follow-up results were all evaluated. The patients were grouped by age and their QOL scored using a telephone interview.

resultsThe mean age (+/-SD) was 8.47 +/- 4.85 (3-25) years, and the mean follow-up period was 6.96 +/- 4.55 (1-23) years. Evaluation of the patients in relation to their fecal continence revealed that 35 (37.6%) had constipation, 22 (23.6%) had fecal soiling, and voluntary bowel movements were absent in 7 (7.5%). Fecal continence was evaluated using the Krickenbeck classification, and it was good in 74 (79.6%), fair in 12 (12.9%), and poor in 7 (7.5%). QOL evaluation of these cases showed markedly decreasing QOL as the cases changed from good to poor fecal continence. Urinary system pathology was detected in 35 (37.6%) of the cases with 22 (23.7%) having severe uropathology. We compared the 22 patients with severe uropathology and 71 cases without severe uropathology for QOL and found the ARM group with severe uropathology to have significantly lower physical QOL, psychosocial QOL, and total QOL values. Reviewing the patients by fecal continence and urinary pathologies together regarding QOL showed that patients with good fecal continence and no additional urinary abnormality had the best QOL. The QOL decreased considerably in both the group with a fecal incontinence problem but no additional urinary abnormality and the group with good fecal continence but serious additional urinary abnormality. The QOL was worst in patients with urinary pathology and fecal incontinence. DISCUSSION: Anorectal malformations constitute a wide spectrum of disease. Urinary anomalies and their complications significantly increase the morbidity in these children even after the correction of the ARM. In the evaluation of the published series, we noted that the main issue was fecal continence, and there was not enough data concerning the urinary system pathologies of the patients when they reach adult ages. Anorectal dysfunction has a negative effect on QOL in ARM patients, but is not life threatening. Such patients can lead normal life although the QOL is affected. However, vesicoureteral dysfunction can cause permanent damage in other organs. This damage may cause mortality depending on the level of the malformation. Evaluating the patients considering fecal continence and urinary system pathology together showed that nearly 10% of the ARM patients had serious problems affecting their long-term QOL related to fecal control, whereas nearly a fourth of the cases had additional anomalies of the urinary system that will affect the QOL despite all treatments used, as the development of pyelonephritis, hypertension, and end-stage renal disease should be expected in these patients.

conclusionUrinary system anomalies in patients with ARM are at least as serious and complex as gastrointestinal system anomalies and create more problems than fecal incontinence during long-term follow-up.
