ABSTRACT
Idiopathic overactive bladder (OAB) is defined as a symptom complex characterized by urinary urgency with or without urinary incontinence, nycturia and increased frequency of micturition without the presence of an infection or other pathological conditions, especially a neurological disease. It is a diagnosis by exclusion. If conservative treatment with behavioral therapy and pelvic floor muscle training alone is not successful, pharmaceutical treatment is recommended according to the OAB staged treatment. For treatment refractory OAB, intravesical injection of onabotulinum toxin A is recommended according to the current guidelines (recommendation level A). The approved dose is 100 U botulinum toxin and is transurethrally injected into the detrusor muscle. The treatment effect lasts on average for 6-9 months and injections can be repeated without limitations. Due to the low rate of complications, the good success rate and the low invasiveness, botulinum toxin offers a good treatment option for treatment refractory OAB.

BACKGROUND: The incidence of small renal masses has been rising over the last few decades. At the same time, mortality of renal cell carcinoma (RCC) is decreasing. These trends can be explained by the availability of improved therapeutic measures and the good prognosis of small renal masses (SRM) turning out to be histopathologically benign or of low malignancy in many cases. OBJECTIVES: The aim of this article is to present epidemiology and diagnostic assessment of SRM. MATERIALS AND METHODS: Statistics, basic research, guidelines. RESULTS: The incidence of SRM is rising due to the widespread use of imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), and contrast-enhanced ultrasound (CEUS). Sensitivity is excellent for CEUS and for CECT in the characterization of SRM, while good specificity values can be reached by MRI. For characterization of complex cystic renal masses, CEUS has good diagnostic accuracy. CONCLUSIONS: Due to improved diagnostic possibilities, SRMs can be diagnosed in early asymptomatic stages. As SRM have a good prognosis and often are of low malignancy therapy, options should be carefully considered; especially in older patients, active surveillance should considered.
