AI Article Synopsis
- Jackstone refers to a rare type of urinary calculi that resembles toy jacks, typically found in the bladder, but this case presents one located in the obstructed renal calyx.
- A 46-year-old man experienced intermittent, painless blood in urine and left flank pain, leading to the discovery of a jackstone during imaging and subsequent surgery for other kidney stones.
- The case highlights that jackstones can form in the renal system, not just the bladder, emphasizing the need to understand their unique characteristics and formation processes for better diagnosis.
Article Abstract
Background: Jackstone is a rare entity of calculi in urinary tracts and has the characteristic appearance resembling toy jacks. They are nearly always reported to occur in the urinary bladder, we first report a rare case of jackstone located in the obstructed renal calyx.
Case Summary: We report a 46-year-old man presenting with intermittent, painless gross hematuria and left flank pain. Urinary computed tomography revealed staghorn stones and secondary hydronephrosis. A jackstone with radiating branches was found in one of the dilated renal calyx. Percutaneous nephrolithotomy was performed and endoscopic images were recorded during the operation. Postoperative stone composition analysis revealed it as calcium oxalate monohydrate stones.
Conclusion: Jackstones can occur in the renal collecting system besides the bladder. The unique appearance and imaging manifestations are the most important factors in the diagnosis of jackstones, and further exploration of the formation mechanism is required.

A 50-year-old patient with a prior history of chronic smoking presented to the emergency department with diffuse abdominal pain, primarily localized to the right hypochondrium and epigastric region, along with nausea, but without fever, vomiting, or urinary symptoms. Laboratory tests were largely unremarkable except for isolated hematuria and a mildly elevated CRP. Given the atypical clinical presentation, a 3-phase abdominal CT scan (without contrast, portal, and delayed phases) was conducted, revealing a horseshoe kidney with an obstructing 4 mm stone at the right ureteral meatus.

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.

Introduction: In adult patients, most ureteropelvic junction obstruction (UPJO) occurs secondarily. Concurrent UPJO with nephrolithiasis is not rare and simultaneous treatment by performing laparoscopic pyeloplasty and endoscopic stone removal has been suggested. In the case of atypical anatomy or previously failed pyeloplasty, a laparoscopic ureterocalicostomy is preferred.

Background: There is still controversy about the best minimally invasive surgical method for the treatment of calyceal diverticulum calculi. We conducted meta-analysis to evaluate the effectiveness and safety of PCNL and FURL in the treatment of calyceal diverticulum calculi.
Methods: We searched Pubmed, Cochrane Library, Web of Science, Embase, Clinical trial platform, CNKI, VIP until April 2024.
