Although it was stated that supine percutaneous nephrolithotomy (PCNL) was associated with relatively shorter surgical times and comparable success and complication rates, there is no consensus in the current literature concerning the safety and efficacy of supine PCNL in patients with horseshoe kidneys. We aimed to compare supine and prone PCNL regarding safety and efficacy in patients with horseshoe kidneys. Data of the patients with horseshoe kidneys who underwent PCNL for renal stones larger than 2 cm between January 2010 and May 2021 were retrospectively reviewed. The study patients were categorized as Group 1 (i.e., supine PCNL-SPCNL) and Group 2 (i.e., prone PCNL-PPCNL). Both groups were compared regarding demographic, clinical, and surgical data. Sixty-five patients were included. Among these patients, 31 (47.7%) were in Group 1, while 34 (52.3%) were in Group 2. Both groups were statistically similar in terms of demographic data, stone characteristics, perioperative parameters, and complication rates (p > 0.05). There was no statistical difference in terms of additional treatment rates, stone-free rates in the postoperative second-day and third-month evaluations (p > 0.05). Mean surgical time was significantly longer in Group 2 (113 ± 17.1 min) than in Group 1 (90.6 ± 11.3 min) (p = 0.000). Although it is traditionally performed in the prone position, the supine approach is as safe and effective as the prone approach. In addition, the supine approach is associated with significantly shorter surgical times. Aunque se ha afirmado que la nefrolitotomía percutánea (NLPC) en posición supina se asocia a tiempos quirúrgicos relativamente más cortos y a tasas de éxito y complicaciones comparables, no hay consenso en la literatura actual sobre la seguridad y la eficacia de la NLPC en posición supina en pacientes con riñón en herradura. Nuestro objetivo es comparar la NLPC en posición supina y en posición prona, en términos de seguridad y eficacia en pacientes con riñón en herradura. Se revisaron retrospectivamente los datos de los pacientes con riñón en herradura sometidos a una NLPC por cálculos renales de más de 2 cm entre enero de 2010 y mayo de 2021. Los pacientes del estudio se clasificaron como Grupo 1 (NLPC en supino-SNLPC) y Grupo 2 (NLPC en prono-PNLPC). Se compararon los datos demográficos, clínicos y quirúrgicos de los dos grupos. Se incluyeron 65 pacientes, de los cuales 31 (47,7%) pertenecían al Grupo 1 y 34 (52,3%) al Grupo 2. Los datos demog
