Purpose: Neurogenic detrusor overactivity (NDOA) is characterized by involuntary detrusor muscle contractions during bladder filling in patients with neurological disorders. Anticholinergic therapy is the primary treatment; however, the reasons for treatment resistance in NDOA are not well understood. This study aimed to identify predictors of treatment failure by comparing urodynamic and frequency-volume chart data between patients with NDOA who respond and patients who do not respond to anticholinergic therapy.

Introduction: Endothelial glycocalyx is a luminal layer which can be damaged by inflammatory agents or pathogens. The endothelial glycocalyx damage is thought to have a role in the formation of renal scars in children who have febrile urinary tract infection and vesicoureteral reflux. This study aimed to compare the blood levels of endothelial glycocalyx components heparan sulfate and Syndecan-1 in children with and without renal scarring due to vesicoureteral reflux-associated febrile urinary tract infection.

Osteoclast-like giant cell tumours of the kidney are extremely rare and usually accompanied by a conventional urothelial neoplasm such as papillary, transitional renal cell, or sarcomatoid carcinoma. Although they have morphological features similar to those of the giant cell tumours in the skeletal system, their counterparts in the urinary system show highly malignant features. Our case is the third primer malignant giant cell tumour of the kidney in the literature.

Prostate cancer is one of the commonest types of malignancy in males. Although prostate cancer has a propensity to metastasize to the bone, metastasis to the mandible is rare. Because of their uncommon incidence, the diagnosis of mandibular metastasis, especially those originating from the prostate, may represent a challenge both for urologists and dentists.
