How do we get fight bladder and chronic obstructive renal failure?

Dysuria is characterized by detrusor hypertrophy then appearance of trabeculations and vesical diverticula, in final stage when bladder is distended non-functional causes chronic retention w/overflow urination. Chronic obstructive renal failure (reflux and bilateral dilatation of pelvic calyx cavities can appear) But No anatomic-clinical correlation, and evolution is not systematically towards appearance of complications, can be latent only functional impairment, never becomes cancer but both are favored by aging.
