And prostatitis and urinary tract infection can be accompanied by varying degrees of odynuria symptoms. Primary acute and chronic nephritis is usually not accompanied by frequent, urgent or painful urination. However, if chronic nephritis is accompanied by urinary tract infection or secondary chronic nephritis is accompanied by neurogenic bladder and urinary tract infection, frequent, urgent and painful urination may also occur.
