Clinical Application of a Two-Step Percutaneous Nephrolithotomy in a Patient With Severe Kyphoscoliosis and a Malrotated Kidney

This case report describes a two-step percutaneous nephrolithotomy (PCNL) in a 22-year-old male who had severe kyphoscoliosis and a malrotated kidney. The operation was performed with the patient under general anesthesia and in the left lateral decubitus position. All stones were successfully removed. No complications occurred during surgery, and the patient recovered well. Regardless of the posed challenges for kidney stone treatment in patients with spinal deformities, PCNL is not only a minimally invasive but also a safe and effective treatment option when done under correct positioning. The success rate is high, and the morbidity rate is low. According to the literature, only 125 cases of PCNL implications in kyphoscoliosis patients have been reported in emerging case reports and case series.
