Short-term outcomes of pyeloplasty vs. nephrectomy in adult patients with ureteropelvic junction obstruction and differential renal function ≤15.

Objectives: To compare symptom resolution and short-term renal function after pyeloplasty or nephrectomy in adults with ureteropelvic junction obstruction (UPJO) in poorly functioning renal units (PFRU).

Methods: Retrospective analysis of adult patients with UPJO and differential renal function (DRF) ≤ 15% who underwent laparoscopic pyeloplasty or nephrectomy. Primary endpoints included symptom resolution and estimated glomerular filtration rate (eGFR) at 12 months.

Mobilization of a peritoneal dialysis catheter using an extra-corporeal magnet: preliminary experimental phase study.

Purpose: To evaluate in an experimental model, the mobility of a novel peritoneal dialysis catheter with a metallic tip (Mag-Cath) using an extra-corporeal magnet.

Materials And Methods: The Mag-Cath was installed in a porcine model under general anesthesia using laparoscopic access. A senior urologist, a urology resident, and a 3rd-year medical student were assigned to complete 2 tasks guided by fluoroscopy: (1) Move the catheter tip from the right flank to the pelvis and (2) move the catheter tip from the pelvis to the left flank.
