Holmium laser lithotripsy had superior initial success and re-treatment rate compared to extracorporeal shock wave lithotripsy (ESWL) in a 2013 trial. [6] 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 ...
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.
Rates increase from 48% for stones located in the proximal ureter to 79% for stones located at the vesicoureteric junction, regardless of stone size. [85] Assuming no high-grade obstruction or associated infection is found in the urinary tract, and symptoms are relatively mild, various nonsurgical measures can be used to encourage the passage ...
Percutaneous nephrolithotomy (PCNL) is a minimally-invasive procedure to remove stones from the kidney by a small puncture wound (up to about 1 cm) through the skin. It is most suitable to remove stones of more than 2 cm in size and which are present near the pelvic region. It is usually done under general anesthesia or spinal anesthesia.
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1] The procedure is useful in the diagnosis and treatment of disorders such as kidney stones and urothelial carcinoma of the upper urinary tract. [1]
Hydronephrosis can also result from the retrograde flow of urine from the bladder back into the kidneys (vesicoureteral reflux), which can be caused by some of the factors listed above as well as compression of the bladder outlet into the urethra by prostate enlargement or fecal impaction in the rectum (which sits immediately behind the ...
If a patient has a stone lodged higher in the urinary tract, the physician may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube that carries urine from the kidney to the bladder.)
[citation needed] A large "staghorn" kidney stone may block all or part of the renal pelvis. The size of the renal pelvis plays a major role in the grading of hydronephrosis. Normally, the anteroposterior diameter of the renal pelvis is less than 4 mm in fetuses up to 32 weeks of gestational age and 7 mm afterwards. [2]
