Is supine position safe and effective for the percutaneous nephrolithotomy? Clinical experiences, tip and tricks in learning curve and PSAA technique.

In previous studies, the supine technique was evaluated in terms of many factors. Process steps were tried to be standardized and improvements were made in the access technique. The supine technique, which uses patient-specific access angle, has similar complication rates as the prone technique. However, the operation and fluoroscopy times are shorter than the prone technique. For surgeons on the learning curve, the supine technique is safe, feasible, and has even shorter operating times with a patient-specific access angle.
