BNO-IVP Blass = Urinary bladder, Nier = Kidney, Overzicht = Examination Synonim : Intravenous urography Excretory urography Intravenous pyelography Use contrast media intravenously Anatomic function: Depict the minor calyx, major calyx, renal pelvis, ureter, urinary bladder. Physiologic function: Assess the kidney function in contrast media filtration and excretion.
BNO-IVP Preparation 2 days prior to procedure the patient should eat only plain porridge (with soy sauce) For procedure done at 8 am in the morning, the patient start fasting from 8 pm the night before Laxatives (Bisacodyl) are given at 6 and 7 pm the night before 5 grams of Magnesium Sulphate are given at 8 pm and 9 pm the night before Laxative suppositoria is given at 5 pm Normal ureum &creatinine (eGFR) Indication Evaluate mass or cyst Urolithiasis (calculi in the kidney or urinary tract) Pyelonephritis Glomerulonephritis Hydronephrosis Trauma Renal hypertension
BNO IVP 1-3’ : Nephrogram phase 5’ : Excretory function 15’ : Pelvocalyceal system, compression is released 30’ : depict kidney, ureters, and bladder 45-60’ : full bladder Post voiding
BNO-IVP Contraindication of compression : Suspected stone Acute abdomen Following abdominal surgery Large abdominal mass Aortic aneurysm Use trendelenburg position instead
Normal BNO IVP
IVP: 5’-30’ - Excretion phase of right kidney is seen at 5’ - No excretion phase seen of left kidney until the end of procedure. Full Blass/Full bladder : The bladder is not full filled with regular wall. The contrast filled the bladder and some contrast is out through the vagina The tract which connects bladder with vagina is not visualized. Conclusion : Vesico vagina fistula Excretory function of left kidney is not visualized. Normal excretory function of right kidney. No ureterolithiasis seen. - Normal bladder.
Antegrade Pyelography Non-functional examination to assess the urinary tract by inserting contrast agent antegrade (in the direction of urine) into the pelvicalyceal system through a nephrostomy catheter. Indications: Shows the location of an obstruction Shows pelvicalyceal system if it cannot be done by intravenous urography As part of a percutaneous nephrostomy examination
Antegrade & Retrograde Pyelography Indication Depict the location, length and lower margin (retrograde) or upper margin ( antegrade ) of obstruction To predict the etiology of the obstruction Depict the pelvocalyceal system if it can not be done by intravenous urography Renal failure Allergy
Antegrade Pyelography Contraindication Acute urinary tract infection Contrast media allergy (although the reaction is less severe than intravenous) Pregnancy Hemorrhagic diathesis and hydatid cyst (contraindication to nephrostomy) Preparation Patients with nephrostomy Not pregnant, no history of allergic to contrast No haemorrhagic diastasis
Antegrade Pyelopgraphy Normal APG
ANTEGRADE PYELOGRAPHY Contrast enters the pelvicalyceal system to the distal left ureter and appears slightly into the urinary bladder. The pelvicalyceal system and proximal ureter are dilated, There is a narrowing of the lumen of the left distal ureter. Impression: The left contrast passage is not smooth. Hydronephrosis grade IV with proximal to distal widening of the ureter e.c. suspected obstruction in the distal left ureter.
Retrograde Urethrography To assess the urethra The contrast media is injected from the distal to the proximal part of the urethra (retrograde or ascending)
Retrograde Urethrography Urethral stricture with periurethral abscess
Retrograde Cystography To assess the urinary bladder The contrast media is injected through the urinary catheter into the urinary bladder Retrograde to the urinary flow
Retrograde Cystography Indication Recurrent urinary tract infection Suspicion of urinary bladder rupture Stone Mass Inflammation Diverticle Fistule Incontinentia Hematuria Measure the urinary volume post micturition Assess the integrity of the anastomosis or suture post operative Contraindication Pregnancy Urethral rupture (contraindication to the urinary catheter insertion)
Retrograde Cystography
Retrograde Urethrocystography To assess the urinary bladder and the urethra. Combination of the retrograde urethrography and cystography . The contrast media is injected through the external urethral orificium to fill the urethra and then the urinary bladder.
Stenosis of urethra pars membranacea
Bipolar Urethrocystography To assess the urethra from the proximal and distal aspects. Retrograde from the distal urethra Antegrade from the cystostomy catheter Patient is asked to void so that the contrast media will fill the proximal part of the urethra. Indication Assess the proximal and distal margin of obstruction (stricture, stone, mass) in the urethra Contraindication Allergy to contrast media
Bipolar Urethrocystography Preparation : Patient empty the bladder before procedure The patient is supine, tilted about 30-45 degrees Adequate traction of the penis
Bipolar urethrocystography
Urethrography : Contrast cannot enter the prostatic urethra and urinary bladder. Obstruction of the pars membranous is seen. Cystography : Contrast appears to fill the bladder. Micturition : Bladder neck is not open, visible contrast is restrained on the bladder. Passage of contrast is not smooth, visible obstruction in the pars membranosa along the 5.12 cm. IMPRESSION: - Obstruction of the membranous urethra.
Voiding Cystourethrography =micturating cystourethrography To assess the vesicoureter valve Indication Suspicion of vesicoureter reflux Recurrent urinary tract infection in children Stress incontinentia Hydronephrosis Contraindication Urinary tract infection
Voiding Cystourethrography
International reflux system Grade I: Reflux into ureter Grade II : Reflux into the ureter and pelvicalyceal system that is not dilated. Grade III : Reflux into the ureter and pelvicalyceal system which is slightly dilated. Grade IV : Reflux into the dilated and tortuous ureter and into the dilated pelvicalyceal system. Grade V : Reflux into a very dilated and tortuous ureter and into a very dilated pelvicalyceal system. The angle of the fornix and the impression of the renal papilla are obliterated.
Voiding Cystourethrography Grade I Grade IV Grade V
Hysterosalpingography Primarily demonstrate the uterus and the salpynx (fallopian tube) Contraindication Pregnancy (performed 7-10 days after the onset of menstruation) Acute pelvic inflammatory disease Active uterine bleeding Indication Infertility assessment Obstruction (can be therapeutic) Anatomic anomaly ( e.g.uterine bicornis ) Intrauterine pathology Endometrial polyps Uterine fibroids Intrauterine adhesion Post operative assessment after tubal ligation or reconstructive surgery
hYSTEROSALPHINGOGRAPHY Done on day 9-10 after the first day of menstruation (not pregnant). The patient is prohibited from coitus during this time. Informed consent. The bladder was empty just prior to the examination.
HYsterosalphingography
Impression: Patent bilateral uterine tubes Uterus within normal limits.
Right Fallopian Tube: The caliber of the pars ampulla and the infundibulum appears dilated. Left Fallopian Tube: The caliber of the interstitial and isthmus does not appear wide. The pars ampulla and pars infundibulum were not visualized. There was no contrast spillage from the left fallopian tube. Impression: Right hydrosalphinx . Left fallopian tube obstruction.
