Pyelolithotomy is a surgical procedure used for the stones located  in the kidney pool . Pyelolithotomy is rarely performed nowadays.  It is particularly suitable for patients who have undergone open abdominal surgeries for other indications. It is most commonly applied in patients who will undergo open pyeloplasty for patients with canal stenosis at the renal outlet. It is also applied in the treatment of minimally branched staghorn stones in the kidney pool of complex collecting systems and in extremely morbidly obese patients.

Since this type of surgery requires general anesthesia, you cannot eat or drink anything for at least six hours before the surgery. This includes chewing gum and sweets.

The operation is usually done through a side incision that allows the best possible access. A catheter will be inserted into your urethra to drain urine from your bladder. Depending on the location and number of stones, the surgery can take between 2 and 4 hours to complete and usually requires a 2-4 nights hospital stay.

You will be able to return home after your catheter, kidney tube, and wound drain have been removed and you can eat, drink, and urinate normally.



You should only wash your wound with water. Soap or powder should not be used directly on your wound until it is completely healed. Your wound will usually dry within 48 hours of surgery, before that you may need to put a dry dressing on your clothing to stop any slight leaks.

You will be given an outpatient appointment, usually 4-6 weeks after your surgery.

If a stent is placed in your kidney during surgery, it is then removed endoscopically. A flexible telescope is passed from the urethra to the bladder so that the tip of the stent can be grasped and removed.

Recovery after surgery takes 4-6 weeks. You should avoid any heavy lifting, straining, or strenuous activities during this time. 

Avoid becoming constipated by maintaining adequate fluid intake and eating fibrous fruits and foods.
