It has become common practice for urologists to prescribe self-catheterization at weekly intervals for the post-urethrotomy patient. After voiding, and using sterile technique, a lubricated Foley catheter is passed into the urethra, through the surgically modified area, into the bladder and allowed to remain in place for up to ten minutes.
Pyeloplasty is a type of surgical procedure performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate. [1]This revision of the renal pelvis treats the obstruction by excising the stenotic area of the renal pelvis or uretero-pelvic junction and creating a more capacious conduit using the tissue of the remaining ureter and renal pelvis.
The presence of profound sedation, low body temperature, and/or a slow heart rate (bradycardia) are usually associated with more severe blood derangements. Ideally, the urethral obstruction is removed or temporarily bypassed with urethral flushing (urohydropulsion) and the placement of an in-dwelling urinary catheter prior to surgery.
In cases requiring a rigid cystoscopy it is not unusual for the patient to be given a general anesthetic, as these can be more uncomfortable, particularly for men. A physician, nurse, or technician will clean the area around the urethral opening and apply a local anesthetic. The local anesthetic is applied direct from a tube or needleless ...
Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention. Complete obstruction of the urinary tract requires prompt treatment for renal preservation. [1]
Risks during surgery include heart problems, pulmonary (lung) complications, development of blood clots , blocking of arteries , and injury to adjacent structures, such as bowel or vascular entities. Inadequate ureteral length may also be encountered, leading to ureteral kinking and subsequent obstruction.
Feline idiopathic cystitis (FIC) is by far the most common form of FLUTD in young to middle-aged cats. It is a disease whose cause is not fully understood but is thought to be related to stress events and a cat's pre-disposition to anxiety, as well as certain lifestyle choices (e.g. a dry food diet, no access to outdoor space).
Obstruction of the ureter most commonly occurs at the site where the ureters are reconnected to the urinary diversion created. A small, hollow, flexible tube called a stent may be placed inside the ureter at the time of surgery to possibly help the reconnection site to heal. This reconnection site is also at risk for leaking urine within the ...
