Tubeless Supine Percutaneous Nephrolithotomy in Calyceal Diverticular Stone

Percutaneous Nephrolithotomy (PCNL) has routinely been performed in prone position as a treatment for calyceal diverticular stone. PCNL is performed supine as an alternate modality for calyceal diverticular stones. The objective of the procedure is to reduce operative time and anaesthetic morbidity during supine tubeless PCNL in calyceal diverticular stone. The series is about three patients with calyceal diverticular stones. These patients underwent supine tubeless PCNL in Galdakao modified supine Valdivia position. There was no intraoperative, postoperative or on follow-up complications in any of the the patients. In all the patients stones were cleared completely in single sitting. Supine PCNL in calyceal diverticular stone could be an alternative with similar outcomes to the standard prone PCNL. It provides an additional benefit of performing the procedure in a single position, which is known to reduce total operating time and also reduces anaesthesia complications.
