Welcome to our Forum am sorry to read of your conditions, I would hope you will find much to assist you here, and also if you were to join COB they have much more information, leaflets , support and contacts that may help you.
Having Parkinsons as I understand often affects the Bladder and Bowel due to the Bladder having most of the nerve endings, for which Parkinsons will sadly not be a help, when needing to pass urine quickly.
In the meantime I wonder if you have read this article
"Bladder and urinary difficulties
Bladder or urinary difficulties are also common in PD. Older research studies indicated the presence of impaired urinary function in slightly over 70 percent of PD patients, although recent studies suggest a more modest frequency of 27 to 39 percent. Despite the frequency of urinary dysfunction, actual urinary incontinence is relatively uncommon. Troublesome incontinence develops in only about 15 percent of individuals.
Unlike bowel dysfunction, which may precede (sometimes by years) the development of motor features in people with PD, urinary dysfunction typically does not become evident until the later stages of the disease. The primary function of the bladder is twofold — to store urine as it is formed and then to empty the urine when it is convenient and socially acceptable to do so. With PD, problems can emerge in both areas.
The most common urinary symptoms experienced by people with Parkinson’s are first, the need to urinate extremely frequently, and second, difficulty in delaying urination once the need is perceived, creating a sense of urinary urgency. These symptoms usually indicate an irritable or overactive bladder that is signaling the brain that it is full and needs to empty when, in fact, it really is not. In addition to urinary frequency and urgency during the daytime, individuals with this problem also may have to get up multiple times during the night to urinate.
Medications that work to block or reduce bladder overactivity can be useful in treating this form of bladder dysfunction. A variety of medications are available for this purpose, including older medicines such as oxybutynin and tolterodine, and newer medications such as solifenacin and darifenacin.
Impairment of bladder emptying is a less frequent but still troublesome feature of urinary dysfunction in Parkinson’s. This difficulty is produced by delay or difficulty in relaxation of the urethral sphincter muscles, which is necessary to allow the bladder to empty. This can result in hesitancy in initiating urination, difficulty in generating a stream and incomplete emptying of the bladder. Dystonia of the urethral sphincter has also been described.
The medications listed above are not helpful for this type of bladder dysfunction and may actually aggravate the difficulty. Medications such as bethanechol may be helpful but intermittent self-catheterization is sometimes necessary. Before initiating these, a doctor must make sure that some unrelated process, such as an enlarged prostate, is not responsible for the problem.
The Bottom line
Both gastrointestinal and urinary problems are frequent features of PD. Awareness of their existence and recognition of their presence are the first necessary steps to adequate management. People with Parkinson’s should not hesitate to bring these problems to the attention of their physicians, especially since effective treatment is often available.
