3. Obstructive Uropathy CLASSIFICATION MECHANICAL blockage: - intrinsic
- extrinsic
Can occur at any level
Might be congenital or acquired
If congenital lesions causing mechanical obstrsevere hydronephrosis with renal damage in the neonate period
Mechanical obstruction of the conduit : UP Junction, bladder neck, urethral meatus

4. Introduction From glomerulus to the penile meatus
Devastating efects on both nephron function and condult function
Frequently associated with infection and stone formations --- renal deterioration
Most common urological problem

5. CLASSIFICATION IMPAIRMENT OF URINE FLOW (without anatomical
obstruction)
Also result in hydronephrosis (functional obstruction)
Functional disorders involve both the ureter and the
bladder and may induce secondary mechanical obstruction
