The experimental thulium fiber laser (TFL) is being studied as a potential alternative to the holmium:YAG (Ho:YAG) laser for the treatment of kidney stones. The TFL has several potential advantages compared to Ho:YAG laser for lithotripsy, including a four times lower ablation threshold, a near single-mode beam profile, and higher pulse rates ...
A partial nephrectomy should be attempted when there is a kidney tumor in a solitary kidney, when there are kidney tumors in both kidneys, or when removing the entire kidney could result in kidney failure and the need for dialysis. Partial nephrectomy is also the standard of care for nearly all patients with small renal masses (<4 cm in size). [22]
The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
Lithotomy from Greek for "lithos" and "tomos" (), is a surgical method for removal of calculi, stones formed inside certain organs, such as the urinary tract (kidney stones), bladder (bladder stones), and gallbladder (), that cannot exit naturally through the urinary system or biliary tract.
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.
Intravenous pyelogram (IVP): A special diagnostic test that follows the time course of excretion of a contrast dye through the kidneys, ureters, and bladder after it is injected into a vein. Retrograde pyelogram (RPG): X-ray study of the kidney, focusing on the urine-collecting region of the kidney and ureters. Antegrade nephrostogram.
Urostomy is most commonly performed after cystectomy, such as may be necessary in, for example, bladder cancer.Other indications include severe kidney disease, accidental damage or injury to the urinary tract, surgical complications because of non-related pelvic or abdominal surgery, congenital defects that cause urine to back up into the kidneys, or urinary incontinence.
Another consequence of this procedure is an increased risk of kidney infections due to bacteria from faeces travelling back up the ureters (reflux). Patients are commonly put on oral prophylactic antibiotics to combat infections in the ureteral tract and kidneys, but this can lead to tolerance of the antibiotic.
