“…Fan et al, 2011 the bladder volume at the first desire to void and cystometric capacity were lower in both men and women diagnosed with OAB and DO [8] . Also we agree with Dekhtiar YM, et al, 2019 who reported reduced maximum cystometric capacity in 75.9% OAB patients, reduced bladder sensation in 70.8% patients, and change in bladder compliance in 43.1% patients [10] .…”

Background: Overactive Bladder (OAB) is defined by the International Continence Society (ICS) as urgency, with or without urge incontinence (UUI), usually with frequency and nocturia, if there is no proven infection or other etiology. Aim of Study:To evaluate the correlation between overactive bladder symptoms (OAB) and urodynamic Detrusor Overactivity (DO) in non neurogenic bladder in both genders.Patients and Methods: We reviewed the records of 202 patients who attended Al-Zahra'a Univesity Hospital between October 2013 and October 2018 with overactive bladder symptoms urgency, with or without urge urinary incontinence usually with frequency and nocturia, with presence or absence of DO in two groups. All patients were subjected to: Full history taking, voiding diary, clinical examination, laboratory investigations, radiological investigations, urodynamic studies (UDS) and cystoscopic biopsies for histopathological examination. Also we evaluate OAB symptoms, urodynamic parameters with histopathological findings. All patients underwent uroflowmetry: The maximum flow rate, average flow rate and voided volume were recorded. Post Voiding Residual urine (PVR) volume was recorded. Cystometry: The intravesical, intra-abdominal, detrusor pressure, first desire to void, strong desire to void, Maximum Cystometric Capacity (MCC), total volume infused, bladder compliance and detrusor overactivity were evaluated. Cystoscopy and random bladder biopsies from all patients and stained with Hematoxylin and Eosin for histopathological examination of smooth muscle, the urothelium, lamina propria, and adventitia. We used another special stain Massons trichrome to visualize collagen and degenerative changes of smooth muscle bundles.Results: Detrusor overactivity DO was diagnosed in (63.36%) 128 OAB patients after urodynamic studies. Of men 42.9% and 36.1% of women with urgency had DO (OAB dry) while 57.1 % of male 63.9% of female patients with urgency and Urge Urinary Incontinence (UUI) were (OAB wet) had DO. Of women 23.8% with no DO were also OAB wet having urodynamic Stress Urinary Incontinence (SUI). Combination of symptoms was more precise in predicting DO in OAB patients.

“…Такие изменения в стенке МП приводят к ее денервации и усилению сократительной активности, а также повышенному выделению уротелием биологически активных веществ, стимулирующих афферентные нервные окончания в подслизистом слое МП, что в том и в другом случаях приводит к учащенному мочеиспусканию и формированию ГАМП. Ухудшение артериального кровотока, приводящее к ишемии детрузора, патогенетически обусловливает применение допплерографии сосудов детрузора в качестве метода разработки нового направления в лечении пациентов с ГАМП [25].

This review is devoted to the study of the prevalence of symptoms of the lower urinary tract and the justification of the use of non-invasive and accessible methods of their diagnosis with an assessment of not only structural, but functional indicators. These include ultrasound examination of the bladder with the determination of functional and maximum volumes and the calculation of the sensitivity index, quantitative and speed indicators of ureteral emissions using color flow mapping, as well as assessment of the blood flow of detzurosis by means of vascular dopplerography.

“…Clinical relevance of IBS without DO is that it may also contribute to overactive bladder (OAB). Urodynamic nature, definition, and the frequency of IBS without DO is still uncertain . One recent study with 478 neurologic patients showed the frequency of IBS (defined as FS < 100 mL) with DO vs IBS (defined as FS < 100 mL) without DO is 156 (17.1%) vs 97 (10.6%), the latter being slightly more uncommon than the former .…”

Aims: Increased bladder sensation (IBS) without detrusor overactivity (DO) is still a matter of debate, regarding its clinical relevance, urodynamic nature, underlying pathology, and management. Among these, we present our data focusing on the urodynamic nature of IBS without DO, by applying our five-grade sensory measure during urodynamics. Methods:We enrolled 400 individuals who visited our laboratory for screening of lower urinary tract function, mostly with neurogenic etiologies. They included 74 control, 87 DO (irrespective of IBS), and 239 IBS (defined as first sensation <100 mL) without DO. During slow bladder filling, we instructed individuals to indicate their sensation in five grades: 1, first sensation to 5, strong desire to void. We also instructed individuals to report other sensations such as pain.Results: The five-grade measure could be performed in all participants without difficulty. None of the participants reported pain or any qualitatively different sensations.Although we defined DO irrespective of IBS, the sensation interval 0 (start) to 1 (first sensation) of subjects with IBS but without DO was significantly less than that of subjects with DO (P < 0.05). Conclusions:The present study results showed that first sensation of subjects with IBS without DO was significantly less than that of subjects with DO (P < 0.05), while the bladder capacities of the two groups were the same. An extremely low-volume first sensation may suggest the possibility of IBS without DO.
