Bilharzial hydronephrosis: a clinicoradiological study
The Journal of Urology
|August 1, 1981
Summary
Hydronephrosis management depends on geographical factors. In Zambia, infection and ureteral motility are key for bilharzial hydronephrosis, while other regions see more strictures and stones. Conservative treatment is often preferred.
Area of Science:
- Urology
- Nephrology
- Tropical Medicine
Background:
- Hydronephrosis, or kidney swelling, can have varied causes and impacts on kidney function.
- Understanding the etiological factors is crucial for effective patient management.
- Geographical variations significantly influence the presentation and progression of hydronephrosis.
Purpose of the Study:
- To investigate the functional status of kidneys in patients with hydronephrosis.
- To identify the primary etiological factors contributing to hydronephrosis in different geographical regions.
- To evaluate the efficacy of conservative versus surgical management strategies.
Main Methods:
- Retrospective analysis of 68 patients with hydronephrosis.
- Assessment of renal function using excretory urography.
- Correlation of clinical findings with etiological factors and geographical location.
Main Results:
- Renal function was relatively preserved in advanced hydronephrosis, except when complicated by infection, stones, cancer, or severe strictures.
- In Zambia, infection intensity and ureteral motility disorders were prominent in bilharzial hydronephrosis.
- In other regions, strictures, stones, ureteroceles, reflux, and bladder cancer were more significant.
Conclusions:
- Geographical variations in etiological factors necessitate tailored clinical management approaches for hydronephrosis.
- Conservative treatment, including periodic dilation for strictures, is advocated due to frequent failure of ureteral reimplantation.
- Supra-infection is uncommon even after multiple surgical interventions, supporting conservative management.
