Abstract
Objective: The aim of this work is to compare between supine and prone PCNL in the management of stag horn and multiple renal stones regarding stone free rate, operative time, DROP of hemoglobin, complication postoperative.
Patient and methods: Eighty patients underwent PCNL for stag horn and multiple renal stones from May 2015 to May 2017 in a prospective randomized manner. There were 40 patients subjected to PCNL in the prone position and 40 patients subjected to PCNL in the complete supine position. The study analyzed the operative time, complications, stone free rate, DROP of hemoglobin.
Results: In our study the operation time was shorter in the supine group than the prone group, most probably related to the time taken for repositioning of the patient. The mean hospital stay in prone group was 1.98±1.05 with a range of 1-7 days and in supine group was 1.40±1.03 with a range 1-6 days. The percentage of hemoglobin DROP was 10 % in the prone position and 7.5 % in the supine position. There was no major complications in either group. The residual stones more than 4 mm were 12% (5 patients) in supine group and 45% (18 patients) in prone group.
Conclusion: Supine PCNL has proved to be superior to prone PCNL as regarding operative time, hospital stay and stone free rates with comparable rate of complications with prone PCNL.
