Dr. Vicentini, an associate of the endourology unit from the University of Sao Paulo, and head of the endourology unit at Brigadeiro Hospital begins by stating that the supine position should be favored. He states that one has to try supine to understand, he says “If you are not convinced that supine is better, I guarantee you that if you start doing supine, in few months most of your cases will be done in supine.” Ever since his hospital tried using the supine position in 2014, the rate of prone PCNL is now 0%. He provides evidence that when a hospital begins trying the supine PCNL, it becomes the new standard. He states that the outcomes between prone versus supine PCNL are similar, that supine is feasible and simply easier to do.
Dr. Lipkin argues that the prone position is still superior because retrograde intrarenal surgery can be done at the same time during the PCNL without need for repositioning. In addition, bilateral simultaneous PCNL has been demonstrated to be safe and effective and this can only be done in prone position. Dr. Lipkin reiterates that prone PCNL provides better stone free rates, equivalent complications, but lower costs.
Dr. Vincentini, the proponent of supine PCNL, finishes the debate by stating that there are no differences in complications, the difference in stone-free rates a minor (78% vs 72%), the supine position provides quicker, less bloody, less supracostal punctures and a high success rate even for complicated anatomy or complex cases.
