Cross-fused renal ectopia (CFRE) is a rare congenital anomaly in which an ectopic kidney crosses the midline and merges with the orthotopic kidney on the other side. Patients with CFRE could present with urolithiasis. The abnormal anatomy and the lack of consensus to treat urolithiasis in these cases present challenges to treatment. In this study, we present a case of renal stone in a CFRE managed through percutaneous nephrolithotomy (PCNL). We present a case of a 59-year-old man with right flank pain. Radiologic studies showed a 2 cm renal pelvis stone in a CFRE. The patient was effectively managed with PCNL. With proper radiologic study and thorough understanding of the aberrant anatomy, PCNL represents a safe and effective treatment for patients with renal stones in CFRE with high stone-free rate and low mortality.

Pain related to percutaneous nephrolithotomy (PCNL) is multifactorial and poorly elucidated. However, understanding the pathophysiology of pain can enable a practical approach to pain management, which can be tailored to each patient. A number of potential mechanisms underlie pain perception in PCNL, and these mechanisms can be leveraged at various points on the perioperative care pathway.

Background: Percutaneous nephrolithotomy (PCNL) is the preferred treatment for large renal stones, yet variability in outcomes arises from patient-specific factors and institutional practices. Understanding complications and predictors of success is essential to improving procedural efficacy.
Objective: This study aimed to evaluate stone clearance rates, complications classified using the Clavien-Dindo system, and predictors of PCNL outcomes, with a focus on improving lower calyx stone clearance.

Backgroud: Perirenal hematoma (PRH) is a notable complication following percutaneous nephrolithotomy (PCNL) with significant implications for patient outcomes. This study aimed to develop a nomogram predictive model for PRH after PCNL.
Methods: Retrospective data from patients who underwent PCNL were analyzed.
Urolithiasis is a multifactorial condition where stone composition is critical in guiding treatment and prevention strategies. Advanced diagnostic techniques, such as infrared spectroscopy, provide precise stone analysis, enabling clinicians to tailor interventions based on specific stone types and associated metabolic abnormalities. Calcium oxalate monohydrate stones often require invasive approaches like percutaneous nephrolithotomy, while uric acid responds well to dissolution therapy.
