BACKGROUND: Although there are international guidelines on diagnosis and management of primary hyperparathyroidism (PHPT), clinical practice varies in different centres. Periodic review of diagnostic work-up, surgical treatment by parathyroidectomy (PTX) and clinical surveillance in nonsurgical treatment group among patients with PHPT is expected to improve the quality of care. We report a retrospective study of cases with PHPT managed at a regional centre in the United Kingdom. METHODS: Clinical data of cases with calcium ≥2...

BACKGROUND: Lesch-Nyhan syndrome is a rare inborn error of purine metabolism marked by a complete deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). Inherited as an X-linked recessive genetic disorder that primarily affects males, patients with Lesch-Nyhan syndrome exhibit severe neurological impairments, including choreoathetosis, ballismus, cognitive dysfunction, and self-injurious behavior. Uric acid levels are usually abnormally high, leading to kidney and bladder stones which often necessitate urological intervention...

Short bowel syndrome (SBS) occurs in patients who have had extensive resection. The primary physiologic consequence is malabsorption, resulting in fluid and electrolyte abnormalities and malnutrition. Nutrient digestion, absorption, and assimilation may also be diminished by disturbances in the production of bile acids and digestive enzymes. Small bowel dilation, dysmotility, loss of ileocecal valve, and anatomical changes combined with acid suppression and antimotility drugs increase the risk of small intestinal bacterial overgrowth, further contributing to malabsorption...

Renal collecting system rupture is a rare manifestation of obstructive uropathy. The majority of cases are attributed to ureteric calculi and extrinsic ureteric compression. The optimal diagnostic image is contrast-enhanced CT scan with delayed phase protocol. Management is usually conservative and generally depends on the etiology, urinomas size, and the presence or absence of kidney failure or infections.

BACKGROUND: Urolithiasis is a condition where crystalline mineral deposits (stones) form within the urinary tract. Urinary stones can be located in any part of the urinary tract. Affected children may present with abdominal pain, blood in the urine or signs of infection. Radiological evaluation is used to confirm the diagnosis, to assess the size of the stone, its location, and the degree of possible urinary obstruction. OBJECTIVES: To assess the effects of different medical and surgical interventions in the treatment of urinary tract stones of the kidney or ureter in children...

Compared to adults, urolithiasis is less common in children, with a definite rise in incidence, especially among young adults (Tasian et al. in Clin J Am Soc Nephrol 11:488, 2016). In the last 25 years, the incidence in children has increased by approximately 6-10% annually, for reasons still unknown, with an associated significant increase in related health care-related expenditures (Hyams and Matlaga in Transl Androl Urol 3(3):278-83, 2014). It has been shown that there is twice as high a risk of chronic kidney disease (CKD) or end stage renal disease (ESRD) in stone formers compared to non-stone formers (Tasian et al...
