  "abstract": "Introduction\n\nIpsilateral renal stones and simple cysts usually require separate procedures or risk urinary extravasation with cyst-transgressing percutaneous techniques. This pilot study evaluated the safety and feasibility of single-tract percutaneous nephrolithotomy (PCNL) combined with intrarenal holmium:YAG laser marsupialization via a non-cyst-transgressing access.Material and methods\n\nNine consecutive patients with renal stones (>20 mm) and a solitary Bosniak I cyst underwent single-tract PCNL. A specific non-cyst-transgressing puncture was used. Following stone clearance, the cyst wall was identified via combined endoscopic and ultrasonographic guidance and incised intrarenally to create a ≥1 cm window.Results\n\nAll procedures were completed with a single tract (median operative time 50 minutes). Stone-free status was achieved in 100% (9/9). Marsupialization succeeded in 8/9 patients; one case with a thick-walled cyst identified intraoperatively was managed by aspiration only. No Clavien-Dindo grade II or higher complications occurred. At 6 months, median cyst diameter decreased by 66% (from 5.6 cm to 1.9 cm), with complete symptom resolution.Conclusions\n\nSimultaneous single-tract PCNL and intrarenal marsupialization via non-cyst-transgressing access is a feasible and safe technique. It eliminates the risk of retroperitoneal extravasation inherent to cyst-transgressing approaches. Careful patient selection, particularly regarding cyst wall thickness, is essential.",
