Assessment of the urinary tract for abnormalities such as blockage or narrowing, the presence of kidney stones, or tumours. [2] Use of duplex ultrasound to determine if there is backward flow of urine, for example in vesicoureteric reflux. Determination of how much urine is in the bladder, for example to assess for urinary retention.
A high osmolar contrast agent such as diatrizoate or a low osmolar contrast agent such as Iotalamic acid with a concentration of 150 mg per ml is used for the procedure. [2] [1] The urinary bladder is catheterised under aseptic technique. The contrast medium is slowly injected or dripped in.
The Mitrofanoff procedure is sometimes performed along with bladder neck closure, [16] but Duckett advised against the closure of the bladder neck. [14] Today, the Mitrofanoff procedure can be performed robotically or using laparoscopic techniques and it paved the way for the creation of other urinary conduits using fallopian tubes, ureters ...
Cystoscopy has similar indications in animals, including visualisation and biopsy of mucosa, retrieval or destruction of urinary bladder stones and diagnosis of ectopic ureters. [9] [10] [11] In turtle and tortoises, cystoscopy has additional value as it permits the visualisation of internal organs due to the thin urinary bladder wall. [12]
Bladder outlet obstruction can be identified during routine prenatal ultrasonography as dilation of the fetal urinary tract [3] and decreased amniotic fluid levels. If dilation of the fetal urinary tract is suspected during pregnancy, an ultrasound of the infant's kidneys and bladder should be obtained after birth.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
A star-shaped Jackstone urolith can be seen in the urinary bladder on this radiograph of the pelvis. Urinary stones may be composed of the following substances: [9] Calcium oxalate monohydrate (whewellite) Calcium oxalate dihydrate (weddellite) Calcium phosphate; Magnesium phosphate; Ammonium phosphate; Ammonium magnesium phosphate (struvite)
Endourology is the branch of urology that deals with the closed manipulation of the urinary tract. [19] It has lately grown to include all minimally invasive urologic surgical procedures. As opposed to open surgery, endourology is performed using small cameras and instruments inserted into the urinary tract.
