Chronic Genitourinary Schistosomiasis (S. haematobium) When Praziquantel Has Not Achieved Treatment Goals

Clinical Scenario

Chronic genitourinary schistosomiasis caused by Schistosoma haematobium, presenting with haematuria, dysuria, and obstructive uropathy, with eggs detectable in urine — and prior Praziquantel treatment that did not meet its stated endpoints.

Previous Treatment — Goals Not Reached

A prior course of Praziquantel failed to achieve:

No vital eggs detectable in urine at 3 months after treatment (persistence indicates treatment failure or reinfection)
Eosinophilia cleared by 6 months after treatment

Next-Step Approach — Partial Overview

The protocol calls for antiparasitic retreatment, and an evidence-based alternative antiparasitic agent may also be considered. Full agent selection, sequencing, and protocol details are available in the structured regimen.
