Classical prone percutaneous nephrolithotomy in a solitary functioning kidney with severe kyphoscoliosis

Percutaneous nephrolithotomy (PCNL) is one of the important options in the management of large (>2 cms) and complex renal calculi. Traditionally the prone position has been used to access the pelvicaliceal system. It has its advantages and disadvantages as well. Several modifications to this position have been suggested and reported by several urologists. We had performed PCNL in an elderly female in classical prone position with severe kyphoscoliosis and solitary functioning kidney.
