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.
Percutaneous nephrolithotomy or, rarely, anatrophic nephrolithotomy, is the treatment of choice for large or complicated stones (such as calyceal staghorn calculi) or stones that cannot be extracted using less invasive procedures.
A nephrostomy or percutaneous nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system (renal pelvis). [2] It is an interventional radiology/surgical procedure in which the renal pelvis is punctured whilst using imaging as guidance.
Lithotripsy is a procedure involving the physical destruction of hardened masses like kidney stones, [1] bezoars [2] or gallstones, which may be done non-invasively. The term is derived from the Greek words meaning "breaking (or pulverizing) stones" ( litho- + τρίψω [tripso]).
A 2013 meta-analysis found LL can treat larger stones (> 2 cm) with good stone-free and complication rates. [ 5 ] Holmium laser lithotripsy had superior initial success and re-treatment rate compared to extracorporeal shock wave lithotripsy (ESWL) in a 2013 trial.
Laparoscopic nephrectomy. The surgery is performed with the patient under general anesthesia.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.
The ileal conduit is not painful; it has no sensation. The ureterostomy stoma retains sensation. Since it has no muscles to regulate urination, urine collects in a bag. [citation needed] There are four common types of ureterostomies: [citation needed] Single ureterostomy: This procedure brings only one ureter to the surface of the abdomen.
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.
