By definition purchase prednisone with american express, all women are tertiary referrals as the only route into the clinic is through the care of the elderly service or urogynecology service prednisone 40 mg free shipping. Consultations take place with both consultants in elderly care and urogynecology order prednisone 20 mg fast delivery, with the support of specialist nurses. All modalities of both services are available to all patients (albeit modified) so that no patient is excluded from any part of the service based on age or disability alone. Effects of Aging on the Bladder Through life, the muscle (detrusor) suffers repeated small insults that continually cause damage and replacement of the muscle fibers with collagen. As a result, the bladder becomes stiffer than it was as collagen is less distensible than detrusor, and second, it contracts with less force as there is less muscle. In addition, there are changes to the nerve supply that are discussed in more detail in the following. Effects of Aging on the Bladder The combination of these two events, described earlier in small repeated insults over time during events such as pregnancy and childbirth or as a result of infections or distension, results in delayed sensation from the nerve changes and reduced capacity from the increased stiffness. Over time, cumulative small injuries such during pregnancy, infection or distension, cause nerve damage resulting in delayed sensation and reduced capacity increase the possibility of urgency and urgency incontinence occurring. A further effect of the replacement of the muscle fibers with collagen is reduced efficiency of contraction leading to incomplete emptying and a reduction in the functional bladder capacity as a consequence from the failure to empty to completion. These effects are mirrored in the urethra, where a replacement of muscle with collagen makes the urethra less compliant. This change is seen as a reduction of the maximal urethral closure pressure (potentially increasing risk of “failure” of the sphincter) and second a reduction in distensibility during voiding reducing the urinary flow rate. Retention Management of the condition as early as possible and prior to crisis if achievable is important to ensure the best clinical outcome for the woman. Management includes treating allied conditions known to be associated with voiding dysfunction such as constipation and treating conditions that may contribute to complications such as atrophic vaginitis. Acute retention itself, however, requires catheterization and attempts to improve voiding with cholinergics have proven disappointing. Specific Effects of Urinary Retention: Physiology and Effects of Distension The bladder is designed as a compliant organ with small pressure changes for a large change in volume. Normal storage pressures run between 0 and 10 mmHg with voiding pressures of up to 25 mmHg and pressures above 10 mmHg are enough to suppress bladder wall perfusion. If this occurs for extended periods of time, the bladder will undergo ischemic changes to the wall. Such a situation may occur when the bladder is over distended and if it is stretched past the normal elastic limit (plastic distension). Effects of Distension Injuries Short-term injuries may be reversible or result in damage, depending on whether the bladder tissue stretches past the elastic limit into plastic deformity. Once overdistension raises intravesical pressure beyond 7–10 mmHg, there is a reduction of the oxygen supply , resulting in ischemic tissue damage. One consequence of this is an alteration in the nerve supply to the bladder, making the muscle more sensitive to the neurotransmitters  in the nerve endings and also a change in the nerve type. First is that the bladder loses its ability to empty (although this will usually recover with time) [13–15]. Second, there is also evidence that reperfusion may add a second layer of injury onto the bladder , and as a result of this oxidative 1045 stress, the ability of the bladder to produce nerve growth factor is reduced after repeated insults . The changes in the bladder’s nerve supply leads to an increase in the so-called “nonadrenergic noncholinergic” fibers, otherwise known as the adrenergic fibers . Repeated insults do reduce this recovery response, and it is probably repeated distensions that create a chronic problem rather than isolated incidents. The resultant changes mean, with time, that the bladder becomes less compliant with filling (reduced capacity) and also has reduced contractility (poorer emptying). The result of these episodes is a replacement of the injured detrusor muscle fibers with collagen. Collagen is a structural protein that, depending on the degree of cross-linking having flexible characteristics, is not a muscle fiber and does not demonstrate the same ability to distend in a compliant manner as detrusor fibers or more importantly to contract. The net effect of this is the bladder starts to lose the elasticity required for compliant distension. Second, the loss of muscle leads to a net reduction in contractile force so the ability to empty may reduce. Impact of Voiding Dysfunction Many women will have suboptimal voiding, but this remains subclinical until symptoms reach the tipping point. First, symptoms of frequency, urgency, poor stream, double voiding, and nocturia develop related to reduced flow, poor contractility, and delayed/reduced sensation. Second, difficulty with conventional treatment for urgency may occur as the reduction in cholinergic fibers may reduce the effectiveness of anticholinergics, while increasing side effects. As such, the introduction of mirabegron, a beta-3 agonist, gives a medication that has different side effect profile and potentially less impact on voiding function. Finally, problems may develop with sequelae of the poor emptying, such as urinary tract infections (exacerbated by atrophic vaginitis), which can be complicated by upper urinary tract infections and a subsequent effect on renal function. Precipitating Factors Situations affecting voiding include concomitant conditions such as constipation and urinary tract infections as well as comorbidities such as diabetes. Various medications can also impact on bladder function such as antihypertensives including rapid-acting diuretics leading to rapid fill and calcium channel antagonists affecting the sensory thresholds. Urinary Tract Infection Urinary tract infections may precipitate retention/voiding difficulties or be sequelae of it. It is important to examine for this and also to send a sample for culture and sensitivity. The importance of microbiology becomes more relevant in chronic conditions and gives evidence as to whether infections are recurrent (as in frequently occurring) or whether they are resistant to clearance, as a result of altered virulence, e. Voiding problems may occur with prolapse and occasionally presents directly as bladder symptoms such as urgency or voiding difficulties but more commonly subclinically, due to the more direct symptoms of a lump/bulge in the vagina. All patients presenting with prolapse should be asked about voiding function prior to surgery. If there is any doubt, then the minimum of a postmicturition residual should be performed, or in more complex cases, urodynamics may be indicated. If poor voiding is identified, then the option of a suprapubic catheter may be considered at the time of surgery being performed for other conditions that may affect mobility. It is, however, important to recognize that older people are a heterogeneous group, many aging with minimal comorbidities and retaining a good level of independence. Others do not age so successfully 1046 and develop multiple conditions, requiring many pharmacological interventions, and are less independent. This latter, frailer group poses a significant challenge, and it is vital to take a holistic approach to their continence assessment and management . It is also important to recognize the common coexistence of the key geriatric conditions, such as incontinence, immobility, falls, and cognitive impairment, as managing one will undoubtedly require recognition and optimization of the others.

An accurate history is required to determine a woman’s symptoms; a thorough examination ascertains the woman’s signs. While this chapter deals with salient aspects of history and examination, it should be remembered that this information alone is not sufficient in the assessment of a woman. Other tools are employed to supplement the information obtained from taking a history and examining a woman. These include bladder diary and questionnaires to determine the impact of symptoms on her quality of life, expectations, and goals. Symptoms are either volunteered by or elicited from the individual or may be described by the individual’s caregiver. The environment, the activities of daily living, and a woman’s ability to cope with her disease can profoundly alter her quality of life. A woman who is always close to a toilet may not notice her urinary frequency, but the same woman with no access to a toilet may have urinary incontinence, wear protective pads, and be severely incapacitated. Women with severe detrusor overactivity may restrict their fluid intake to less than 200 mL per day. On direct questioning, the urinary problem may not appear severe, with a normal diurnal urinary frequency, and it is only with a frequency/volume chart that a complete picture of the severity of symptoms can be determined. The volume of urine excreted relies not only on fluid intake but also on the secretion of antidiuretic hormone, which is impaired in diabetes insipidus. The circadian secretion of this hormone may be affected in women suffering nocturia and nocturnal polyuria . The use of standardized terminology during the taking of the history is essential as it ensures accurate characterization of symptoms. Women often fail to understand terms such as stress incontinence with a majority thinking that this relates to being mentally stressed and then leaking . Therefore, symptomatic women may misclassify their urgency incontinence as stress incontinence due to this misunderstanding. This is then clarified into an easily understandable list of graded symptoms using a standard questionnaire (Figure 28. In a large study of women in five countries, the overall prevalence of urinary incontinence was 13. In another large cross- sectional web-based survey of over 15,000 women, the prevalence of stress urinary incontinence at least “sometimes” was found to be as high as 31. Current data describe a wide variation in prevalence rates of incontinence in women, but the latest International Consultation on Incontinence reports that 10% of all adult women report leakage at least weekly and 25%–45% experience occasional leakage . A diagnosis based on history corresponds to urodynamic diagnosis in only up to 55% of women . However, the use of a self-completed symptom questionnaire does produce a better relationship between urinary symptoms and urodynamic diagnosis . The use of a bladder diary to enable patients to record fluid intake, output, and incontinence episodes for at least 24 hours can be extremely helpful in the initial assessment of urinary incontinence. It may also be therapeutic as it provides insight into bladder behavior, and it can be utilized to monitor the effectiveness of treatment during follow-up. In addition, symptoms should be taken into consideration during the urodynamic test as the provocative maneuvers should mimic conditions encountered by the woman in her normal daily activities and lead to her urinary symptoms. A 90-year-old woman with urgency and no stress incontinence is an inappropriate candidate for performing “star jumps” with a full bladder! When questioning women complaining of urinary symptoms, all symptoms complained of should be explained in a woman’s own words. Stress incontinence is the term used to describe the symptom of urinary leakage that occurs with effort or exertion or on coughing or sneezing. The severity of each symptom and its effect on the woman’s quality of life are noted, as improvement can be achieved through directing treatment to relieve the troublesome symptoms. The length of time that the symptoms have been present discriminates between transient and established incontinence and whether this has changed over time.

D Clinical Problem-solving Review 1 A 15-year-old fairly built and fairly nourished healthy boy presents with deterioration in his scholastic performance and episodes of emotional lability over triffes during the past some 6 months. Could his emotional symptoms and scholastic regression be related to acne and gynecomastia? Review 2 A 17-year-old college-going girl, suspected to be indulging in premarital sex, is a source of considerable anxiety for her parents. What else can be done to safeguard against premarital sex and adolescent pregnancy on a large scale? Yes, both could well be the cause of his scholastic regression and emotional symptoms. Apart from treatment of acne, this adolescent needs to be counseled in a conducive environment about the physiological basis of acne as well as bilateral breast enlargement. Once he is assured that these are just transient phenomena, his anxiety shall take a U-turn. He should be advised to wash face frequently, and avoid cosmetics and squeezing the lesions. Medication is in the form of antibiotics and local application of cis-retinoic acid (isotretinoin). There is every risk of her getting pregnant, placing her at risk of obstetrical and perinatal complications such as toxemias, postpartum hemorrhage, postpartum infection, stillborn baby and low birthweight baby. If abortion is opted for, this being usually conducted by unscrupulous quacks, places the teenager at a special risk. Pediatrician’s endeavor should be good counseling aimed at primary prevention of adolescent pregnancy. If avoidance of sexual activity is not workable, she needs an appropriate contraceptive advice. Yes, introduction of sex educations in schools can assist in safeguarding against premarital sex and adolescent pregnancy.
