The clinician must be aware of the possible presentations of renal diseases and gather these symptoms and signs which form recognized diseases and syndrome What is the possible presentations suggesting renal problem ?,Clinical presentation of renal disease,The patient is asymptomatic, but an abnormality has been detected on clinical or laboratory examination which indicates an underlying renal disorder. The patient complains of a symptom or has a physical sign which directly or indirectly indicates underlying renal diseases The patient has a systemic disease which is known to be associated with renal involvement The patient has a family history of an inherited renal disorder.,Symptoms of urinary tract disease,A fever; dysuria; frequency; loinpain/abdominal pain; urinary inconsistency;offensive
