Urinary symptoms and investigation

Urinary system :

US is extra peritoneal system composed of two kidneys located in the upper abdomen protected by thoracic cage, each weighs about 150 g.Each kidney supplied by main renal artery from aorta, divided into 5 segmental branches and drained by renal vein to the inferior vena cavaUrinary bladder :
Muscular organ located in the pelvis, acts as urine reservoir during resting time and discarding urine via urethra during the process of urination by the action of detruser muscles Contraction ..Normal capacity about 350-400 cc

Urinary symptoms:1-Haematuria 2-pain3-altered bladder function4-incontinence5-nocturnal enuresis6-associated symptoms1-Haematuria :-Macroscopical-Microscopical-Terminal-Total-Early-Intermitent-Persistant

2-Pain:

1.Renal pain
2.Ureteric colic
3.Bladder pain
4.Perineal pain
5.Urethral pain
3-Incontinence : involuntary loss of urine
-Continuous incontinence
-Stress incontinence
-Urge incontinence
-Overflow urinary incontinenceAssociated symptoms&sign :
1-GIT :
-Autonomic
-Organ relationship
-Peritoneal irritation
2-Mass or swelling
3-Failure to thrive
4-Uremia

urine examination :

1-Dipstick…RBC,,,protein,,,nitrite,,,,screenig
2-GUE
3-Cytological
4-Bacteriological
5-Biochemical :Haemoglobin ;Myoglobin;Bilirubin;Glucose;Electrolyte and protein
24h urine for calcium; uric acid; oxalate,protein

: INVESTIGATION

1-Renal function test:More than 70% of renal function must be lost before renal failure becomes evident
2-Blood urea & serum criatinin 3-radiological:- KUB (kidney,ureter,bladder):-A-BonesSB-Soft tissueC-StonesA plain radiograph of the abdomen and pelvis includes the area above both adrenal glands and extends to 2 cm below the symphysis pubis
KUB: site, skin, sex, stones, psoas shadow, skeleton, and soft tissue shadow

Urinary symptopms and investigations


Urinary symptopms and investigations


IVU:-Function Of the collecting system , anatomy of the kidneys , hydronephrosis and:filling defect .
C.I. allergy and renal failure. A-Retrograde ureterpyelography
B-Antegradepyelography
C-Cystography (MCUG)
D-Urethrography
4-Ultrasonography5-Color Doppler uls

Urinary symptopms and investigations

6-Transrectalultrasonography

7-CT scan (computed tomography):
-Tumor size , site , invation .
-Lymph node
-Invation of the renal vein & vena cava
-Staging & follow up of testicular tumor-CT can accurately characterize the nature of tissue in the lesion.
-CT is useful in the preoperative evaluation and staging of tumors.
-CT has replaced IV urography as the primary modality for the assessment of suspected renal injuries and their complications
-For the evaluation of patients with acute flank pain, unenhanced spiral CT is more sensitive in detecting calculi than EXU

8-MRI
9-Radioisotop scanning Nuclear imaging :Tc 99m Diethylenetriaminepenta-acetic Acid 99mTc-DTPA Mercaptoacetyltriglycine 99mTc-MAG3 Technetium Tc 99m Dimercaptosuccinic Acid 99mTc-DMSA
It gives the split function of each kidney
10-Isotop bone scanning FOR STAGING KIDNEY&PROSTATE CANCER
11-Urodynamic study
12-Endoscopy : invasive /Urethroscope, cystoscope ureteroscope and renoscope.Nephroscopy
13-Retrograde ureteropyelography : invasive14-Cystourethrography :
Contrast-enhanced imaging of the lower urinary tract provides valuable information on the function and anatomy of the bladder and urethra
15-Angiography :
Currently, CT, MRI, and ultrasonography have supplanted angiography for most diagnostic indications, providing equivalent and at times greater information with markedly decreased morbidity and risk
