surgical diseases of urinary tract 1+2 Flashcards
upper urinary tract
kidneys and ureters
lower urinary tract
bladder and urethra
history questions
- neuter status
- continence? (control of bladder)
- can patient void bladder normally?
- unproductive urination?
- vocalisation whilst urinating?
- house soiling?
- smell of urine?
- blood in urine?
- frequency of urination
- drinking more than usual?
initial investigations
- bloods (haem)
- urinalysis (USG, dipstick, sediment, culture)
- radiography
- ultrasonography
instruments and equipment for urinary surgery
- abdominal retractors
- stay sutures/small retractors
- tubes for cystotomy
- urethral catheters
- suction
- magnification
- sterile cotton buds
surgical diseases of the kidney
- neoplasia
- trauma
- renoliths (renal stones)
- kidney disease secondary to uretic disease
renal neoplasia clinical signs, contraindications
carcinoma- most common in dogs
lymphoma- most common in cats
clinical signs- palpable mass, haematuria
contraindications for surgical intervention:
- pulmonary metastases
- bilateral neoplasia
causes of renal trauma
- RTA
- dog bite
renal stones
- similar to uroliths
- seen in concurrent cronic renal failure
- can be dissolved through renal diet and antibiotics
- surgery not recommended
subcutaneous ureteral bypass (SUB)
- indicated in patients with uni/bilateral blocked ureters
- can be causes by calcium oxalate stones (can’t be medically dissolved)
- tubing placed within kidney and connected to bladder
kidney disease secondary to ureteric disease
can be caused by trauma to ureters, ureteroliths (obstruction)
- managed by ureterotomy or intra-ureteral stent
nephrectomy indications
- neoplasia
- trauma
- chronic pyelonephritis
- idiopathic haematuria
- ureteral abnormalaties
surgical diseases of the ureters
- trauma during another surgery
- ureteroliths
- ureteral ectopia
ureteral ectopia definition
- congenital abnormality (dogs)
- ureters open into the urethra, bypassing the bladder
- can happen in the bladder (intramural)
treatment= neoureterostomy - monitor for stranguria post op
- common for incontinence post op
surgical diseases of the bladder
- uroliths (bladder stones)
- neoplasia
- trauma
