Treatment of Bladder Stones in Adults and Children: A Systematic Review and Meta-analysis on Behalf of the European Association of Urology Urolithias…

2019

Bladder stones (BS) constitute 5% of urinary stones. Currently, there is no systematic review of their treatment.To assess the efficacy (primary outcome: stone-free rate [SFR]) and morbidity of BS treatments.This systematic review was conducted in accordance with the European Association of Urology Guidelines Office. Database searches (1970-2019) were screened, abstracted, and assessed for risk of bias for comparative randomised controlled trials (RCTs) and nonrandomised studies (NRSs) with ≥10 patients per group. Quality of evidence (QoE) was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.A total of 2742 abstracts and 59 full-text article…

Long-term follow-up results of vesico-ureteral reflux treated with subureteral collagen injection (SCIN).

2000

Endoscopic sub-ureteral injection is at the present a widely used technique for the treatment of vesico-ureteral reflux and it has a good range of efficacy, from 50% up to 90% in relation to different grades. In this paper we report our 1-7 year follow-up results of sub-ureteral collagen injection (SCIN).Between 1991 and 1997 we treated with SCIN 129 refluxing ureters in 93 children (60 females and 32 males), mean age 2.1 years (range 3 months-5 years). Fifty-five children had monolateral, but 37 had bilateral reflux. Distribution among different grades was 42 ureters (32.5%) grade 2, 63 (48.8%) grade 3, 24 (18.6%) grade 4. Children were treated with injection of highly purified bovine coll…

Segmental Ureterectomy Versus Radical Nephroureterectomy in Older Patients Treated for Upper Tract Urothelial Carcinoma

2022

Introduction: The world population is ageing and surgical procedures for older patients are associated with higher perioperative morbidity and mortality rates than in younger patients. Segmental ureterectomy (SU) has been proposed as an alternative to radical nephroureterectomy (RNU) for selected upper tract urothelial carcinomas (UTUC), to reduce post-operative morbidity, and preserve renal function. The aim of this study was to compare RNU and SU in terms of post-operative complications, functional outcomes, and overall survival (OS) in older patients treated for UTUC. Materials and methods: Data of patients aged 75 years or older and treated for UTUC were included. The primary outcome wa…

Congenital reduction in number of nephrons accelerates renal damage, and limits proximal tubular growth response to release of neonatal partial urete…

2012

Aim: to analyze the evolution of the response to persistent partial ureteral obstruction (PUO) and obstruction/release (PUO/Rel) in mice with 50% reduction in the number of nephrons from 21 days of age (time of weaning) to 42 days of age (adulthood). Methods: C57/BL6 wild-type (WT) and mice with oligosyndactylism and 50% reduction of nephron number (Os/+), were subjected to sham operation or PUO in the first 2 days of life. Additional mice underwent release of obstruction at 7 days (PUO-Rel). The study was performed in kidneys harvested at 21 and 42 days. Using histomorphometry, glomerular area (GA) was determined by PAS staining, and fractional proximal tubular (PT) mass and intact glomeru…

CONGENITAL REDUCTION IN NUMBER OF NEPHRONS IMPAIRS PROXIMAL TUBULAR GROWTH IN THE CONTRALATERAL KIDNEY DURING PARTIAL UNILATERAL URETERAL OBSTRUCTION

2013

PURPOSE To compare the response of the contralateral (CL) kidney during partial unilateral uretaral obstruction (PUO) and from obstruction/release (PUO/Rel) to sham-operated kidneys in both wild-type (WT) mice and mice with 50% reduction of nephron number (Os/+) MATERIAL AND METHODS C57/BL6 WT and mice with oligosyndactylism and 50% reduction of nephron number (Os/+), were subjected to sham operation or PUO in the first 2 days of life. Additional mice underwent release of obstruction at 7 days (PUO-Rel). All kidneys were harvested at 6 weeks (adulthood). Using histomorphometry, glomerular number and area were determined by PAS staining, and proximal tubular (PT) mass and injury to the glome…

Role of antibiotic prophylaxis in antenatal hydronephrosis: A systematic review from the European Association of Urology/European Society for Paediat…

2017

Summary Background The benefits and harms of continuous antibiotic prophylaxis (CAP) versus observation in patients with antenatal hydronephrosis (ANH) are controversial. Objective The aim was to determine the effectiveness of CAP for ANH, and if beneficial to determine the best type and regimen of antibiotic and the most harmful to provide guidance for clinical practice. Methods A systematic literature search was performed in databases including Medline, Embase, and Cochrane in June 2015. The protocol was prospectively registered to PROSPERO (CRD42015024775). The search started from 1980, when maternal ultrasound was first introduced into clinical practice. Eligible studies were critically…
