Urination problems, although often perceived as temporary discomfort or an inevitable part of aging, actually represent a serious aspect of urological health that can significantly disrupt daily functioning and quality of life for millions of people worldwide. Symptoms such as frequent urination, urgency, waking up at night due to the need to empty the bladder, weak urine stream, straining during urination, or the feeling of incomplete bladder emptying are collectively known as Lower Urinary Tract Symptoms (LUTS) and can be caused by numerous clinical conditions. Most commonly, this involves benign prostatic hyperplasia (BPH) in middle-aged and older men, but symptoms can also be associated with urinary tract infections, neurogenic bladder disorders, overactive bladder, or anatomical anomalies of the lower urinary tract – conditions that require professional medical assessment and often long-term monitoring. Given that LUTS symptoms are often mistakenly interpreted as a natural part of aging that one must learn to live with, a significant number of people do not seek professional help in time, resulting in worsening symptoms and increased risk of more serious complications. Urinary retention, frequent urinary tract infections, bladder stone formation, and even kidney function impairment are just some of the consequences of neglecting these symptoms – which is why it is crucial to use public health tools, education, and innovative digital solutions to increase access to information and provide effective support for people facing these difficulties on a daily basis.
The initial idea is based on years of clinical practice of the client – a leading Croatian urologist
The idea for developing a mobile application came from the daily work of a renowned Croatian urologist who has been diagnosing and treating patients with various urological issues for decades, tracking their symptoms, habits, and behavioral patterns over extended periods. In his practice, it was observed that numerous patients, regardless of age and diagnosis, spontaneously shared an interesting observation: listening to the sounds of running water – for example, dripping from a faucet, babbling brooks, shower sounds, or ocean waves – significantly helped them initiate and maintain the act of urination. It was precisely based on this clinical observation that the client approached Prolink with the idea to systematically analyze this phenomenon, although known from everyday experience and often used in informal advice, and turn it into a functional digital tool that would be available to patients at any time on their mobile devices. In the clinical context, the mechanism explaining the effect of water sounds is based on the reflex response of the nervous system – sounds reminiscent of water can stimulate the parasympathetic nervous system, which plays a key role in the contraction of the detrusor muscle, the main muscle of the urinary bladder responsible for its emptying. The relaxation and reduction of tension caused by these auditory stimuli can lead to easier initiation of urination, especially in people who have so-called inhibitory dysfunction or psychological barriers associated with urination in public or unfamiliar places.
Application functionalities and development principles based on neuroergonomics
Based on the client's clinical insights and interdisciplinary collaboration between the urologist, user interface designers, and Prolink's digital tool experts, we developed a mobile application designed to be intuitive, unobtrusive, and accessible to a wide range of users regardless of their technical literacy or age. The application contains a rich collection of high-quality water sounds, carefully selected and classified according to the type of auditory stimulus – from gentle faucet dripping, through constant river flow, to ambient sounds of oceans, rain, or streams – with each sound optimized for different needs and situations in which users may find themselves. The application design is based on principles of neuroergonomics and minimalism, allowing users simple and quick use in everyday situations, for example at home in the morning after waking up, at work when feeling the need to urinate, or in healthcare facilities during hospital stays. The application's interactivity also includes the ability to precisely adjust volume, playback duration, and sound sequences, and users can create their own personalized playlists based on individual experiences of relief and preferences for certain types of sounds.
Psychological and neurophysiological aspects of listening to water sounds – why this works
The role of auditory perception in physiological processes such as urination is increasingly recognized in scientific literature, and the application developed for the client is based precisely on these insights – the sound of running water can serve as an external trigger for conditioned reflex responses, similar to Pavlov's reflex, where a stimulus becomes associated with a physiological response through conditioning. In people with difficult urination, there is often a component of psychological stress or discomfort that inhibits the normal physiological reflex – anxiety about the inability to urinate further complicates the situation, creating a vicious cycle of tension and blockage. Auditory stimulation can act as a distraction, redirecting attention from anxious thoughts to sound, but also as a signal that activates already adopted behavioral patterns associated with urination, thus facilitating the initiation of micturition. This is especially useful for people suffering from so-called "shy bladder" (paruresis), where urinating in public or unfamiliar places is problematic, which can seriously limit daily activities and social interactions. Furthermore, numerous studies have shown that nature sounds, especially water, have a relaxing effect on the brain – they reduce the activity of the amygdala, the part of the brain associated with threat perception and stress, and encourage the creation of alpha waves associated with states of mental relaxation and calmness. The combination of these effects can have direct benefits for people with psychosomatic components of urinary problems, where psychological factors play a significant role in the manifestation and maintenance of symptoms.
Application use in clinical and everyday contexts – from hospital to home use
The application can be used independently by patients, but also as a supplement to other treatment methods for urological issues under specialist supervision – it is not a replacement for medical treatment, but support that can ease daily functioning and improve quality of life. In hospital settings, it can help patients after bladder or prostate surgery to more quickly reestablish normal urination functions, reducing discomfort and speeding recovery with minimal cost and side effects. In nursing homes, where problems with incontinence and urinary retention are extremely common and present a major challenge for healthcare staff, the application can be a simple and non-invasive tool for daily care support, reducing the need for catheterization and other invasive procedures. Also, parents of young children who have difficulty learning bladder control can use the application as an aid in shaping positive habits and routines, associating the sound of water with the act of urination in a way that helps the child understand and perform this natural function.
Digital solutions as support for urological self-care and patient empowerment
The development of this application for the client – a leading Croatian urologist – illustrates how digital technology, when focused on specific health needs of users and based on real clinical observations, can be a powerful tool in promoting self-care and health preservation in a way that is accessible to everyone, regardless of place of residence or financial means. This blurs the boundary between traditional medicine and modern technological solutions, creating space for innovations based on real experiences of patients and experts, not just theoretical concepts. By providing a simple yet scientifically based tool available at any time on a mobile device, the application contributes to better information, emotional security, and an active role for users in managing their own health – which is especially important in chronic conditions where daily self-care is key to maintaining quality of life. It is important to emphasize that the application is not a diagnostic tool or a replacement for medical treatment, but additional support that can help users manage their symptoms more easily while under doctor supervision – regular use in combination with medical advice and lifestyle changes, such as regulating fluid intake, avoiding caffeine and alcohol, and strengthening pelvic floor muscles, can significantly contribute to improving symptoms and overall quality of life.
