OBJECTIVES. (1) To evaluate the safety and efficacy of supine percutaneous nephrostomy, nephrolithotomy, and combined percutaneous nephrolithotomy and ureteroscopic lithotripsy. (2) To describe the skill-acquiring process in supine procedures and share our initial experience. DESIGN. Three-staged case series with prospective data collection. SETTING. Two public hospitals in Hong Kong. PATIENTS AND INTERVENTION. Stage 1: Forty patients indicated for percutaneous renal access were recruited for supine percutaneous nephrostomy with prospective data collection. Stage 2: A prospective comparative study of percutaneous nephrolithotomy involving 60 patients allocated non-randomly to a supine (n=25) or prone (n=35) approach was conducted. Stage 3: Data of 11 patients who underwent simultaneous supine percutaneous nephrolithotomy and ureteroscopic lithotripsy were prospectively captured. RESULTS. Stage 1: The procedural success rate was 100%. The mean operating time in unilateral procedures was 44 minutes; one patient had perinephric haematoma as a complication. Stage 2: Overall stone-free rates for prone and supine procedures were 46% and 68%, respectively (P=0.087), and mean operating times were 122 and 123 minutes, respectively (P=0.905). Stage 3: Of the 11 patients, six were rendered stone-free after the first combined procedure, and one experienced transient postoperative fever. There was no major complication. CONCLUSION. Percutaneous nephrolithotomy was feasible via both prone and supine approaches. With the exception of staghorn stones, the supine percutaneous approach was an equally safe and effective option for patients with specific conditions favouring such an approach. The ability to incorporate simultaneous ureteroscopic lithotripsy was an additional benefit of adopting the supine approach.
