The placement of a catheter into the bladder through a small incision made through the abdominal wall just above the pubic bone is known as

Nephrostomy

Explanation:

Nephrostomy is a surgical procedure usually performed when there is difficulty for produced urine to leave the kidney and find its way to the urinary bladder. The difficulty happens as a result of blockage around the kidney.

When blockage happens and urine cannot leave the kidney, it results to a damage to the kidney. Hence, those experiencing kidney blockage which could be as a result of kidney stone or ovarian cancer usually undergo nephrostomy.

During nephrostomy, a small incision is made on the patient's skin and the nephrostomy tube or catheter is passed through the skin into the urinary tract. The other end of the tube is connected to a urinary bag.
