Pelvic Lymph Node Dissection With Polymer Ligation Clips Significantly Reduces Hospital Stay Compared to Vessel Sealer: A Retrospective Study.

Introduction Lymphocele is a typical complication of pelvic lymph node dissection (PLND) in robot-assisted radical prostatectomy (RARP). This study aimed to compare postoperative lymphatic leakage between the polymer ligation clip and vessel sealer, and evaluated the costs associated with the former. Methods The study enrolled patients who underwent RARP with PLND at our institution between April 2018 and March 2023 and were treated with a vessel sealer (LigaSure Blunt Tip 44 NC; Medtronic, Dublin, Ireland) until September 2021, and Hem-o-lok polymer ligation clips(Teleflex, Wayne, PA, USA) thereafter.

Early recovery of urinary continence after robot-assisted radical prostatectomy is associated with membranous urethra and neurovascular bundle preservation.

Objectives: We investigated the correlation between surgical outcomes and postoperative urinary continence recovery in robot-assisted radical prostatectomy (RARP).

Methods: Patients who underwent RARP in our institution (n = 195) were included in this study. Preserved urethral length (PUL) was assessed during the procedure.

Urine output and resultant osmotic water shift are major determinants of plasma sodium level in syndrome of inappropriate antidiuretic hormone secretion.

Although various formulas predicting plasma sodium level ([Na]) are proposed for correction of hyponatremia, it seems that an anticipated [Na] frequently exceeds or falls below the measured [Na], especially in syndrome of inappropriate antidiuretic hormone secretion (SIADH). The causative factors of the fluctuation have never been investigated clearly. The aim of this study was to identify the determining factors for accurate prediction of [Na] by comparing data from previously proposed formulas and a novel osmotic compartment model (O-C model).
