Abstract
BACKGROUND: Pelvic ectopic kidney is a kind of congenital malformations of urinary system due to the failure of ascent from the pelvis to the abdomen during development. CASE PRESENTATION: A 39-year-old man was referred to the urology department of our hospital for abdominal pain for half a month. Radiographic studies revealed stones in pelvic ectopic left kidney. Laparoscopy-assisted ultrasound-guiding percutaneous nephrolithotomy (PCNL) was performed. Postoperative plain film revealed that the patient achieved a stone-free status. CONCLUSIONS: Laparoscopy-assisted ultrasound-guiding PCNL is a safe alternative for the treatment of stones in pelvic ectopic kidney with a high stone-free clearance.
