Urinary tract stone disease is seen at a level of 1%-2% in childhood (< 18 years). In recent years, however, there has been a marked increased in pediatric stone disease, particularly in adolescence. A carbohydrateand salt-heavy diet and a more sedentary lifestyle are implicated in this increase. Although stone disease is rare in childhood, its presence is frequently associated with metabolic or anatomical disorders or infectious conditions, for which reason there is a high possibility of post-therapeutic recurrence. Factors such as a high possibility of recurrence and increasing incidence further enhance the importance of minimally invasive therapeutic options in children, with their expectations of a long life. In children in whom active stone removal is decided on, the way to achieve the highest level of success with the least morbidity is to select the most appropriate treatment modality. Thanks to today's advanced technology, renal stones that were once treated only by surgery can now be treated with minimally invasive techniques, from invasion of the urinary system in an antegrade (percutaneous nephrolithotomy) or retrograde (retrograde intrarenal surgery) manner or shock wave lithotripsy to laparoscopic stone surgery. This compilation study examined studies involving the RIRS procedure, the latest minimally invasive technique, in children and compared the results of those studies with those from other techniques.

Turkish Journal of Urology

“…Especially in the pediatric age group endemicity of urolithiasis in Turkey seems to be the reason of this finding. [10] In our list 16 (31.3%) publications are directly related to the field of andrology which demonstrates our serious contribution to andrology literature.…”

Objective: Citation is the name given for a scientific publication in order to be used as a reference by another publication. In this study, we reviewed the most frequently cited publications in urology from Turkey. Although the number of citations is not completely definitive on its own, it shows the importance and effect of the publication. Besides the number of citations directly determines the impact factor of the journals and this factor is generally used in the evaluation of the quality and importance of the journal. Material and methods:On March 7-14, 2016, 51 studies with highest number of citations from Turkey are determined from Science Citation Index Expanded database index and the journals in which studies are published, the authors of the publications, their cities and departments, study types, publication date of the studies and the number of citations are recorded. Results:The most frequently encountered subjects in the publications that are mostly cited from Turkey are urolithiasis (23.5%), infertility (15.6%), benign prostatic hyperplasia (11.7%), sexual dysfunction (11.7%) and bladder carcinoma/urothelial carcinoma (9.8%). Distribution of 51 publications is as follows: 18 case series, 11 randomized study, 7 non-randomized study, 6 study, 3 review, 3 cross-sectional studies and 3 survey studies. Of all the studies, 68.6% are from Ankara, İstanbul and İzmir and 72.5% of them have originated from the university hospitals. Conclusion:It is important to show the most cited Turkish publications in order to show the contribution in the world literature regarding to urology. The most cited publications in Turkey belong to urolithiasis and andrology areas. When the citation analysis publications in urology and different areas both in Turkey and in the world, it is observed that the number of our qualified publications is at acceptable levels.

“…Standard treatments, including dialysis, may be needed for acute renal failure. Surgical removal or invasive procedures may be necessary for larger stones [51]. As melamine stones were associated with urate, alkalinization of the urine has been suggested to help prevent or dissolve current stones as described above [13,37,52].…”

Melamine Toxicity

2010

Melamine contamination of infant formula in China and its health effects highlight the safety of the global food supply especially as it relates to formula-fed infants. Melamine is a widely used industrial chemical not considered acutely toxic with a high LD 50 in animals. The data available on acute and chronic human exposure to melamine have been limited and extrapolated from animal data. Pet food contamination in 2004 and 2007 showed stone formation and illness in animals when melamine was co-ingested with cyanuric acid. The recent outbreak in infants showed that melamine ingested in large doses may cause stones and illness without significant ingestion of cyanuric acid or other melamine-related chemicals. This may be due to increased uric acid excretion in infants and formation of melamineuric acid stones. Diagnosis and treatment of infants exposed to melamine requires further study. Clinical signs and symptoms in infants are nonspecific. The stones may be radiolucent and are not consistently seen on ultrasound. The use of alkalinization of the urine for treatment has been proposed, but is of unproven benefit. The FDA and other regulatory agencies have recommended acceptable levels of melamine in foods for consumption. Melamine ingestion has been implicated in stone formation when co-ingested with cyanuric acid, but will cause urinary stones in infants when large amounts of melamine alone are ingested.
