[Late urinary tract complications of schistosomiasis]

Significant portion of the urologic and nephrologic patients in Yemen are treated because of the early and late complications of schistosomiasis (bilharsiasis). During two years 79 patients with renal insufficiency and complications have been examined and treated by the authors. In combination with moderate restricted renal functions hepatosplenomegaly and signs of portal hypertension were observed in female patients. Granulomatous infiltration, calcification and malignous tumour of the urinary bladder was found in men. Stricture of the ureter, uni- or bilateral consecutive hydronephrosis was detected frequently. In addition to inflammatory components bladder, ureteral and renal stones were verified. In the course of treatment 45 percutaneous nephrostomies were performed and an anterograde pyelography was carried out in 60 patients. Ureteral recanalisation was accomplished by means of an ureter stent in 8 cases. Because of serious uremia maintenance haemodialysis was performed in 52 patients. The aim of this work is to contribute to recognise the disease in early stage and emphasize the importance of establishing diagnosis as early as possible and stress the role of the appropriate causal and symptomatic treatment.
