BACKGROUND: Predictive tables and scoring systems can predict stone clearance. However, there is a paucity of evidence regarding the prediction of complications during percutaneous nephrolithotomy (PCNL), particularly in children, which remains under-researched. To our knowledge, no studies have evaluated the risk factors for febrile urinary tract infection (FUTI) after pediatric PCNL. OBJECTIVES: To assess the predictive factors of FUTI in prepubertal children after PCNL and determine whether any prophylactic cephalosporins are superior for decreasing the FUTI rate...

INTRODUCTION: We are a reporting on the indications, techniques, and limitations of robotic surgery in the management of renal stones disease. Robotic surgery is a good tool to manage large kidney and ureteral stones, particularly in patients with anatomic anomalies. We describe three techniques in managing staghorn kidney stones: robotic anatrophic nephrolithotomy, robotic pyelolithotomy, and robotic nephrolithotomy. MATERIAL AND METHODS: Robotic pyelolithotomy (RP) is ideal for patients with large renal pelvis and partial staghorn stone with a wide extra-renal pelvis...

Accelerating anthropogenic climate change threatens to destroy coral reefs worldwide through the processes of bleaching and disease. These major contributors to coral mortality are both closely linked with thermal stress intensified by anthropogenic climate change. Disease outbreaks typically follow bleaching events, but a direct positive linkage between bleaching and disease has been debated. By tracking 152 individual coral ramets through the 2014 mass bleaching in a South Florida coral restoration nursery, we revealed a highly significant negative correlation between bleaching and disease in the Caribbean staghorn coral, Acropora cervicornis ...

Global warming is rapidly emerging as a universal threat to ecological integrity and function, highlighting the urgent need for a better understanding of the impact of heat exposure on the resilience of ecosystems and the people who depend on them 1 . Here we show that in the aftermath of the record-breaking marine heatwave on the Great Barrier Reef in 2016 2 , corals began to die immediately on reefs where the accumulated heat exposure exceeded a critical threshold of degree heating weeks, which was 3-4 °C-weeks...

Focal Xanthogranulomatous pyelonephritis is a rare chronic inflammatory condition of kidneys which usually is associated with postrenal obstruction or renal stone leading to chronic bacterial infection and eventually chronic glomerular inflammation. About 90% of cases are of the diffuse type and associated with staghorn renal calculi. The case presented in this paper is of the focal type in a 58-year-old diabetic female. Interestingly she did not have symptoms or laboratory presentation of chronic renal bacterial infection except for elevated ESR...

Laparoscopic heminephrectomy was performed in a 64-year-old woman with a chronically obstructed horseshoe kidney moiety. More than 3000 cc of pyonephrosis was drained through two percutaneous nephrostomy tubes for infection control before left moiety laparoscopic resection. This case report attests to the feasibility of laparoscopic resection of a massively obstructed horseshoe kidney when performed in a staged manner after prolonged drainage. Since an incision was required for removal of the large specimen, ligation of the horseshoe isthmus was completed through the same incision after hilar control and laparoscopic mobilization of the moiety were completed...

Staghorn stones are large branching stones that fill part of all of the renal pelvis and renal calyces and they can be complete or partial depending on the level of occupancy of the collecting system. Although kidney stones are commoner in men, staghorn stones are less often reported in men compared to women and they are usually unilateral. Due to the significant morbidity and potential mortality attributed to staghorn stones, prompt assessment and treatment is mandatory. Conversely, conservative treatment has been shown to carry a mortality rate of 28% in 10-year period and 36% risk of developing significant renal impairment...

PURPOSE: Percutaneous nephrolithotomy (PCNL) is the preferred surgical treatment for staghorn stones. Two approaches are commonly employed to gain access into the collecting system which consists of either an upper pole (UP) approach or lower pole (LP) approach. However, opinions vary on which approach offers the best access and outcome. In this study, we aim to challenge the traditional paradigm that staghorn stones are most effectively treated through a prone UP approach. We herein report our institutional experience using a prone LP access in PCNL for patients with complete staghorn stones...

Owing to the fragile kidney and relative small collecting system of pediatric patients, urologists were always reluctant to treat pediatric urolithiasis with PCNL. Here we conduct a study to assess the effectiveness and safety of pediatric patients with renal calculi <6 years.A total of 88 pediatric patients (99 kidney units) <6 years underwent the ultrasound (US)-guided minimally invasive percutaneous nephrolithotomy in our institute from March 2006 to April 2016. The mean age was 30.9 months (range, 7-72 months)...

Human generated noise is changing the natural underwater soundscapes worldwide. The most pervasive sources of underwater anthropogenic noise are motorboats, which have been found to negatively affect several aspects of fish biology. However, few studies have examined the effects of noise on early life stages, especially the embryonic stage, despite embryo health being critical to larval survival and recruitment. Here, we used a novel setup to monitor heart rates of embryos from the staghorn damselfish ( Amblyglyphidodon curacao ) in shallow reef conditions, allowing us to examine the effects of in situ boat noise in context with real-world exposure...

Predators sample the available prey community when foraging; thus, changes in the environment may be reflected by changes in predator diet and foraging preferences. We examined Forster's tern (Sterna forsteri) prey species over an 11-year period by sampling approximately 10,000 prey fish returned to 17 breeding colonies in south San Francisco Bay, California. We compared the species composition among repeatedly-sampled colonies (≥ 4 years), using both relative species abundance and the composition of total dry mass by species...

This study is aimed at establishing a baseline on the genetic diversity of the Acropora corals of Sabah, North Borneo based on variations in the partial COI and CYB nucleotide sequences. Comparison across 50 shallow-water Acropora morphospecies indicated that the low substitution rates in the two genes were due to negative selection and that rate heterogeneity between them was asymmetric. CYB appeared to have evolved faster than COI in the Acropora as indicated by differences in the rate of pairwise genetic distance, degrees of transition bias (Ts /Tv ), synonymous-to-nonsynonymous rate ratio (dN /dS ), and substitution patterns at the three codon positions...
