Overview
Schistosomiasis affecting the urinary bladder, often referred to as bladder schistosomiasis, results from parasitic infection by Schistosoma haematobium. It can lead to chronic inflammation, fibrosis, and various urological complications including hematuria, dysuria, and bladder wall thickening 13.Diagnosis
Clinical Symptoms: Hematuria, dysuria, lower abdominal pain, and recurrent urinary tract infections 13.
Urine Examination: Detection of schistosome eggs or ova in urine samples 13.
Imaging: Ultrasound or CT urography to assess bladder wall thickness and identify structural abnormalities 13.
Cystoscopy: Visual confirmation of bladder lesions and tissue biopsy for histopathological examination 13.Management
Antiparasitic Therapy: Praziquantel is the first-line treatment, typically administered at 75 mg/kg/day for one dose or two divided doses over three days 13.
Supportive Care: Pain management, hydration, and prophylactic antibiotics to prevent secondary infections 13.
Surgical Intervention: Reserved for complications such as bladder stones, severe obstruction, or intractable bleeding 13.Special Populations
Pediatrics: Transition planning is crucial for adolescent patients to ensure smooth transfer to adult urological care, focusing on building independence and addressing specific urological concerns 1.
Elderly: Age-related changes in bladder function may exacerbate symptoms; management should consider the impact of aging on bladder capacity and compliance 3.Key Recommendations
Initiate Praziquantel Therapy for confirmed cases of bladder schistosomiasis at 75 mg/kg/day for one or two doses (Evidence: Strong 13).
Evaluate and Address Transition Needs in adolescent patients to facilitate a smooth transfer to adult urological care (Evidence: Moderate 1).
Monitor for Age-Related Bladder Changes in elderly patients to tailor management strategies effectively (Evidence: Expert opinion 3).References
