The occurrence of a large ureteric calculus in a transplanted kidney, originating from a donor, is a rare but significant complication. It poses risks such as urinary obstruction, septicemia, and potential loss of allograft function. In this case, we report our first use of the direct in-scope suction technique during antegrade flexible ureteroscopy lithotripsy. This method successfully removed a donor-derived ureteric calculus in a kidney transplant recipient. The procedure resulted in complete stone removal, and the patient experienced a favorable postoperative recovery without additional adverse events.

Background: Medical Expulsive Therapy (MET) has been recommended as an established modality for the treatment of distal ureteral stones due to its clearance rate, pain control, and patient satisfaction while having minimal morbidity in comparison to other urologic interventions. In some studies, a combination of medications has been used, which we assessed in this network meta-analysis (NMA).
Methods: We conducted systematic searches in PubMed, Scopus, and Web of Science to identify relevant trials published between 2001 and 2024.

Emphysematous pyelonephritis (EPN) is a rare but severe necrotizing infection often associated with diabetes, ureteral obstruction, and gas production in the renal parenchyma and perinephric area. This report describes a 54-year-old man with type 2 diabetes who presented with right lumbar pain and was diagnosed with EPN complicated by right ureteral calculi and perinephric gas accumulation. Despite initial improvement with fluid resuscitation, antibiotics, and drainage, inadequate blood glucose control led to a worsening of the infection, eventually involving the psoas major muscle and iliac vessels.

Urinary stones (urolithiasis) have been categorized as kidney stones (renal calculus), ureteric stones (ureteral calculus and ureterolith), bladder stones (bladder calculus), and urethral stones (urethral calculus); however, the mechanisms underlying their promotion and related injuries in glomerular and tubular cells remain unclear. Although lifestyle-related diseases (LSRDs) such as hyperglycemia, type 2 diabetic mellitus, non-alcoholic fatty liver disease/non-alcoholic steatohepatitis, and cardiovascular disease are risk factors for urolithiasis, the underlying mechanisms remain unclear. Recently, heat shock protein 90 (HSP90) on the membrane of HK-2 human proximal tubular epithelium cells has been associated with the adhesion of urinary stones and cytotoxicity.

Purpose: To report on in-vivo intrarenal pressure (IRP) during flexible ureteroscopy for treatment of kidney stones while using the novel flexible and navigable suction ureteral access sheath (FANS).
Methods: A retrospective observational analysis was performed for 25 patients undergoing routine flexible ureteroscopy for treatment of renal stones between February 2024 and June 2024 from two centres in Canada. The LithoVue Elite™ ureteroscope (Boston Scientific Corp.
