Is percutaneous nephrolithotripsy feasible in ipsilateral lumbar incisional hernia? A report of two patients

Incisional hernia refers to an abdominal wall defect at the site of a previous surgical incision. In this paper, we describe two patients who previously underwent open kidney stone surgery several years ago and had the ipsilateral recurrent stones. They were both managed by a mini percutaneous nephrolithotripsy (PCNL) to treat kidney stones. Case 1 was a 50-year-old female with right recurrent staghorn stones after 5 years of open surgery and required two PCNL procedures to achieve stone-free status. Case 2 was a 74-year-old male with significant comorbidities who had a right 27 mm recurrent kidney stone after 10 years of open nephrolithotomy. Both patients experienced no postoperative complications after PCNL. These cases show that in cases of lumbar incisional scar hernias, mini PCNL with ultrasound guidance and proper patient positioning can be an optimal approach for kidney stone treatment.
