Department of Urology and Pediatric Urology, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University, Jerusalem, Israel.

Introduction:  Ureteric reimplantation due to ureterovesical junction (UVJ) obstruction enjoys high success in the short term. However, renal function after reimplantation must accommodate the numerous changes in the pediatric urinary tract that occur along with child development that may theoretically cause an occult loss of renal function. The purpose of this study was to evaluate whether improved renal function after ureter reimplantation for antenatal diagnosed UVJ obstruction remains stable after puberty. Read More

Introduction: Enhanced recovery programs (ERP) is aimed at reducing a patient's surgical stress response, specifically by reducing the duration of catheterization. In cases of colorectal surgery, there is pronounced heterogeneity in urinary catheterization, which is largely explained by fear of acute urinary retention (AUR).

Objective: The objective of the work is to report on the current literature on postoperative urinary catheterization following colorectal surgery, particularly with regard to the risk of AUR, and thereby contribute to the standardization of perioperative practices. Read More

Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

Anatomical endoscopic enucleation of the prostate (AEEP) differs from other surgical techniques for benign prostatic obstruction (BPO) in that it removes the entire benign prostatic hyperplasia (BPH) component of the prostate. We summarise the main advantages of AEEP compared to other surgical techniques for BPO. These include better urodynamic relief of bladder outlet obstruction, superior outcomes for urinary retention even in the presence of impaired detrusor contractility, safe and effective for any size prostate, and superior durability compared to vaporisation and resection techniques.

The acronym EEP, coding for transurethral Endoscopic Enucleation of the Prostate, was introduced in 2016 by the European Association of Urology (EAU) guidelines panel on management of non-neurogenic male lower urinary tract symptoms (LUTS) and benign prostatic obstruction (BPO). Since then, a laser-based treatment, Holmium Laser Enucleation of the Prostate (HoLEP), and the current-based treatment of bipolar enucleation of the prostate (BipoLEP) are equally appreciated as valuable options for the management of benign prostatic obstruction (BPO). This was mainly inspired by the results of two meta-analyses on randomized controlled trials, comparing open prostatectomy with either Holmium Laser Enucleation of the Prostate (HoLEP) or bipolar enucleation of the prostate (BipoLEP).

Anticancer drug nephrotoxicity is an important and increasing adverse drug event that limits the efficacy of cancer treatment. The kidney is an important elimination pathway for many antineoplastic drugs and their metabolites, which occurs by glomerular filtration and tubular secretion. Chemotherapeutic agents, both conventional cytotoxic agents and molecularly targeted agents, can affect any segment of the nephron including its microvasculature, leading to many clinical manifestations such as proteinuria, hypertension, electrolyte disturbances, glomerulopathy, acute and chronic interstitial nephritis, acute kidney injury and at times chronic kidney disease.

Background: Indwelling ureteral stents are commonly used in pediatric surgeries for kidney stones and urinary tract obstruction, but often require instrumentation or anesthesia for removal. We evaluated the use of novel magnet devices to remove indwelling ureteral stents with a distally attached magnetic bead. Since the forces required for stent removal are unknown, we aimed to characterize and quantify the forces required for stent removal for future prototype testing. Read More

Background: Anterior urethral valves (AUV) and associated anterior urethral diverticula (AUD) are a rare cause of congenital lower urinary tract obstruction. They occur 25-30 times less frequently than posterior urethral valves (PUV) and historically tend to have a less aggressive presentation and outcome.
