PURPOSE: To evaluate the effectivity and safety of percutaneous nephrolithotomy (PCNL) in the treatment of solitary kidney with staghorn stones in prone position or in completely supine position. MATERIALS AND METHODS: We retrospectively reviewed the records of 18 patients with staghorn stones in a solitary kidney treated with PCNL. 12 patients underwent PCNL in prone position (group A). 6 patients underwent PCNL in completely supine position (group B). Demographic data, number of accesses, operating time, stone free rate, hemoglobin values, hospital stay and complications were studied. Serum creatinine, systolic and diastolic blood pressure, and new onset hypertension were determined preoperatively and postoperatively at 3 months. RESULTS: No blood transfusions were required and no abdominal or thoracic organ injuries were reported in both groups. The mean operative time was 104 minutes (range: 72-145 minutes) and 128 minutes (range: 80-170 minutes), respectively. The I stage stone free rate was 91.7 % and 83.3 %, respectively. There was no new onset hypertension by the end of follow-up in both groups. Both groups showed a similar fall in serum creatinine at 3 month follow-up period (p = 0.004 and 0.029, respectively). Systolic blood pressure showed a statistically significant improvement in group B (p = 0.034). CONCLUSION: PCNL is safe and has an acceptably high stone free rate in patients with solitary kidneys in both prone and completely supine position. At short-term follow-up, systolic blood pressure had improved in PCNL in supine position.
