The presence of renal The presence of renal disease in a patient may be disease in a patient may be

detected because ofdetected because of

• Presentation with a Presentation with a symptom or clinical sign symptom or clinical sign that indicates an underlying that indicates an underlying renal disorderrenal disorder

• The presence of a The presence of a systemic disease known to systemic disease known to involve the kidneyinvolve the kidney

The presence of renal The presence of renal disease in a patient may be disease in a patient may be

detected because ofdetected because of

• A family history of A family history of inherited renal diseaseinherited renal disease

• The finding of The finding of asymptomatic urinary asymptomatic urinary abnormalities or disordered abnormalities or disordered renal function testsrenal function tests

Symptoms of renal disease include

• Disturbance in the act of Disturbance in the act of micturition micturition

• Alteration in the amount Alteration in the amount and and appearance of appearance of urine urine

• Pain : renal, ureteric, Pain : renal, ureteric, vesical, and vesical, and urethral urethral

• General symptoms of renal General symptoms of renal diseasedisease

Disturbance in the act of Disturbance in the act of micturitionmicturition

FrequencyFrequency

Passing urine more often Passing urine more often than usual without increase than usual without increase in the amount of urinein the amount of urine

Disturbance in the act of micturition

Frequency

Results fromResults from

• Irritation of the bladderIrritation of the bladder

• Reduction in the capacity Reduction in the capacity of the of the bladderbladder

• Pressure from a pelvic Pressure from a pelvic tumourtumour


Dysuria

Pain in passing urinePain in passing urine

Usually results from disease Usually results from disease of the of the

• BladderBladder

• ProstateProstate

• UrethraUrethra


DysuriaDysuria

Pain experienced prior to , Pain experienced prior to , during, or following during, or following micturition usually in the micturition usually in the urethra or suprapubic urethra or suprapubic region region

Commonly due to infection Commonly due to infection of lower urethral tractof lower urethral tract


Retention of urine

Occurs in

• Obstructive lesions of the urethra

• Disease of the spinal cord

• Coma


Incontinence of urine

Seen in

• Cerebrovascular lesions

• Paraplegia

• Multiple slerosis

• Prolapsed uterus with cystocele


Nocturia

Passing urine in the night ( commonly associated with polyuria)

Other causes• Prostatism

• Cystitis

• Bladder tumours


Stranguary

Severe supra pubic pain associated with inability to pass urine

Seen in

• Cystitis

• Bladder tumour


Hesitancy

Delay in initiating the urine flow

Seen in males with prostatism


Pneumaturia

Passing of air bubbles in the urine

Most often caused by a fistula between the bladder and the colon as a result of

• Diverticular abscess

• Malignant tumour

Alteration in the amount of urine

Polyuria - over 3000 ml per day

Oliguria - less than 300 ml per day

Anuria - neglible urine output


Polyuria causes • Diabetes Mellitus

• Diabetes Insipidus

• Psychogenic polydipsia

• Chronic renal failure

• Hypokalemia

• Hypercalcemia


Oliguria

Seen in acute renal failure

Pre renal failure – Shock

Haemorrhage

Dehydration

Cardiac failure


Oliguria

Seen in acute renal failure

Intrinsic renal failure –

Acute glomerulonephritis

Acute tubular necrosis


Anuria

Must be differentiated from retention of urine

Causes include

• Infarction of a kidney or both kidneys

• Bilateral cortical necrosis

• Complete obstruction of both ureters

Alteration in the appearance of urine

Haematuria – Red or smoky brown colour


Causes of haematuria

Painless – Urinary tract obstrution

Tuberculosis

Urogenital tumors

Glomerulonephritis

Renal cystic disease


Causes of haematuria

Painful – Renal calculi

Urinary tract infection

Reflux nephropathy

Renal papillary necrosis

Renal infarction


Urine become blackish or coca cola in colour

• Haemoglobinuria

• Myoglobinuria


Frothy urine

Commonly due to proteinuria


Proteinuria

A small amount of protein ( usually less than 100 mg ) is normally excreted in the urine daily in healthy people


Proteinuria

50 % of proteins excreted in urine derive from plasma proteins

Remainder of proteins- postglomerular • Secretary products of distal tubular cells ( Tamm Horsfall proteins )

• From lower urinary tract ( Prostate, Urethral and semen )


Proteinuria

Urine tests for protein best performed on fresh concentrated urine and an early morning sample is the best


Proteinuria

Significant proteinuria

• Physiological

• Pathological


Proteinuria

Physiological

( Proteinuria less than 1000 mg / L )

When disappears lying supine is called orthostatic proteinuria


Proteinuria

Transient proteinuria without renal damage seen in• Cold exposure

• Vigorous exercise

• Febrile illness

• Congestive cardiac failure


Proteinuria

Pathological proteinuria

( Proteinuria more than 1000 mg / L )


Proteinuria

Pathological proteinuria

Commonly seen in

• Glomerular disease

• Tubular disease


Proteinuria

Amount is very small or no proteinuria in some renal diseases

• Polycystic kidney disease

• Renal scarring

• Obstructive uropathy


Proteinuria

Albumin - 30 mg per day excreted in healthy people

Conventional urine tests give positive tests when albumin level exceeds 300mg / day

( 200 mg / L )


Proteinuria

Microalbuminuria ( Misnormer )

Albumin excretion rate more than normal ( 30 mg/day ) , but less than the detectable level with conventional tests ( 300 mg/ day )

30 - 300 mg /day

20 - 200 mg / L


Proteinuria


Seen in

• Diabetic nephropathy

• Hypertensive renal disease


Proteinuria


Detection needs special reagent strips


Urine become turbid with

• Infection

• Precipitated urates

• Precipitated phosphates


Urine colour gets darkened on standing

• Porphyria

• Alkaptonuria


Drugs causing discolouration of urineTetracycline Yellow

Sennakoat Orange

Desferrioxamine Reddish Brown

Phenindione Pink

Nitrofurantoin Brown

Rifampicin- Red

Methylene Blue Green

Methyl Dopa Grey

Metronidazole Darkening Of urine

Pain – as a manifestation of renal disease

Burning sensation or dyscomfort over suprapubic region - Cystitis

Perineal pain or rectal pain – Prostatitis

Pain felt in the flank, hypochondrium or iliac fossa – Renal pain


Acute obstruction of ureters due to stone or blood clot – Colicky pain radiates from loin to groin and to the testicle in the male

Chronic obstruction – less severe pain and sometimes no pain


Enlarged kidneys – dull, nagging or flank pain

Acute glomerulonephritis – typically painless

General symptoms and signs of renal disease

Fever – Urinary tract infection

may be associated with renal abnormality


Dyspnoea - fluid overload in renal impairment

metabolic acidosis in renal

impairment

pleural effusion in nephrotic

syndrome


Oedema ( facial and dependent )

chronic kidney disease

nephrotic syndrome


Pruritus – in chronic kidney disease

Distal brown discolouration of nails - in chronic kidney disease


Pallor – in chronic kidney disease

Hyperpigmentation

in chronic kidney disease

Symptoms of renal disease

Symptoms of ureamia

Anorexia

Lethargy Nausea

Poor sleep Poor concentration Itching

Restless legs
