A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
A kidney can be removed through an open incision or by laparoscopic surgery. For the open procedure, the surgeon makes an incision in the side of the abdomen to reach the kidney. Depending on circumstances, the incision can also be made midline. The ureter and blood vessels are disconnected, and the kidney is then removed. The laparoscopic ...
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral.Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic.
Treatment of xanthogranulomatous pyelonephritis involves antibiotics as well as surgery. Removal of the kidney is the best surgical treatment in the overwhelming majority of cases, although polar resection (partial nephrectomy) has been effective for some people with localized disease.
After being sedated for days, Mullins woke up to the news she'd be losing all of her limbs. The long-time nurse was surprisingly calm when everything was explained to her. She said she would take ...
Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
Renal biopsy (also kidney biopsy) is a medical procedure in which a small piece of kidney is removed from the body for examination, usually under a microscope. [1] Microscopic examination of the tissue can provide information needed to diagnose, monitor or treat problems of the kidney.
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.
