Urinary schistosomiasis has been subject of numerous studies around the Taabo dam but the scanning aspect has never been studied. This study was therefore designed to determine the scan morbidity of urinary schistosomiasis among school children in six localities around the Taabo dam. A parasitological examination of urine and the scanner of bladder, ureters, kidneys, liver and spleen were performed in each school child selected. Urinary schistosomiasis was recorded at rates ranging from 1.67% to 68.97% indicating that it is no longer present at high levels in all localities around the dam. In this area, more than 65% of the infected had a mild infection and morbidity were mostly moderate with a scan severity index between 2 and 4. The majority of the 329 scanned school children presented abnormalities in the spleen (67.17%), bladder (40.43%) and liver (13.07%). Among the bladder lesions, mucosal irregularities were more frequent (27.36%), followed by thickening of the wall (14.89%) and weight (4.86%). They were found in all localities even in non-parasitized. Given the heterogeneity of the prevalence of parasitological and scan morbidity indicators, three strategies for reducing morbidity should be adapted to the epidemiological context of different homes.

Abstract: (french)
La bilharziose urinaire a fait l'objet de nombreuses études autour du barrage de Taabo, mais l'aspect échographique n'a jamais été étudié. Cette étude avait donc pour objectif de déterminer la morbidité échographique de la bilharziose urinaire chez les écoliers de six localités autour du barrage de Taabo. Un examen parasitologique des urines et un examen échographique de la vessie, des uretères, des reins, du foie et de la rate ont été réalisés chez chaque écolier sélectionné. La bilharziose urinaire a été enregistrée à des taux variant de 1,67% à 68,97% indiquant qu'elle n'est plus présente à des taux élevés dans toutes les localités autour du barrage. Dans cette aire, plus de 65% des parasités ont eu une infection légère et les morbidités ont été majoritairement modérées avec un index de sévérité échographique compris entre 2 et 4. La majorité des 329 écoliers échographiés a présenté des anomalies au niveau de la rate (67,17%), de la vessie (40,43%) et du foie (13,07%). Parmi les lésions vésicales, les irrégularités de la muqueuse ont été plus fréquentes (27,36%), suivis des épaississements de la paroi (14,89%) et des masses (4,86%). Elles ont été retrouvées dans toutes les localités et même chez les non parasités. Au regard de l'hétérogénéité des prévalences des indicateurs parasitologique et échographique de la morbidité, trois stratégies de réduction de la morbidité devraient être adaptées au contexte épidémiologique des différents foyers.
