The Larsson frequency/volume chart is not a substitute for cystometry in the investigation of women with urinary incontinence. Postmenopausal hormone therapy and incident urinary incontinence in middle-aged women. Prevalence in men varies from 1% to 39% depending on the definition used, variation in populations, response options, and participation rates (Tikkinen et al, 2013). However, this included various forms of urinary symptoms, such as postmicturition incontinence, nocturnal enuresis, and urinary leakage with no definable cause. However, because it must be preceded by urgency, the terminology has changed to urgency urinary incontinence (Abrams et al, 2009; Toozs-Hobson et al, 2012).
This could perhaps be related to the decreased packing density of submucosal collagen during aging (Levy and Wight menopause images generic ginette-35 2 mg fast delivery, 1990). Further studies are required to establish the relationship between compliance changes and the passive mechanical elements of the bladder wall that make up its structural protein matrix. BladderWallElastinandMatrix Elastic fibers are amorphous structures composed of elastin and a microfibrillar component located mainly around the periphery of the amorphous component (Rosenbloom et al, 1995). Elastin fibers are sparse in the bladder compared with collagen but are found in all layers of the bladder wall (Murakumo et al, 1995). During this 6 weeks, the bladder compliance increases and the bladder becomes overdistended. The nonfibrillar matrix in the stroma is largely composed of a gel of proteoglycans and water. The arrange ment of the proteoglycans in the matrix creates a compartment of tissue water that has a viscous behavior when it is subjected to deformation. The motor innervation of the bladder smooth muscle is from the postganglionic parasympathetic nerve fibers, although intramural ganglia can exist within the bladder wall. It is unlikely that every smooth muscle cell receives direct synaptic contact; the presence of gap junctions allows excitation to propagate throughout the smooth muscle syncytium. Postjunctional receptors, such as muscarinic and purinergic receptors, are present on the smooth muscle cell. When activated by their respec tive agonists, these receptors initiate the excitationcontraction events (see later section) of the smooth muscle. Some investigators have found that the detrusor smooth muscle has afferent innervation that could mediate afferent signals related to smooth muscle activity (Gillespie et al, 2006). The prostatic urethra then extends throughout the length of the gland, terminating at the prostatic apex. The individual cells within a bundle are connected together to form a functional syncytium. This architecture differs from the discrete circular and longitudinal smooth muscle layers in the ureter or gastrointestinal tract. FemaleUrethra In women, the urethra extends throughout the distal third of the anterior vaginal wall from the bladder neck to the meatus. The urethra is composed of tissues that aid continence in addition to the urethral sphincter. A network of vascular subepithelial tissue in women contributes to a urethral seal effect and promotes continence. Urinary continence is maintained during elevations in intraabdominal pressure by three processes.
Diseases
Some systems contain a third channel women's health clinic campbelltown purchase ginette-35 2 mg with mastercard, which can be used for measuring urinary leakage objectively using an absorbent electronic (capacitance change) nappy pad (Robertson and Neil, 1998). This allows accurate data to be obtained on the relationship of urinary leakage to detrusor activity. This must be done with great care and frequent quality checks to make sure that urethral and abdominal catheters are properly transducing pressure. In addition, the reader must be able to identify physiologic artifacts (after contractions and aberrant rectal pressures) and technical artifacts (movement or variation in pressure and lack of balance in the transducer lines), which could have an impact on the interpretation of the study. For example, if the patient complains of stress incontinence, a standard protocol of exercises can be performed and recorded. It was suggested that prolonged periods of catheterization and irritation from multiple catheters could be an issue, but the data about frequency of autonomic dysreflexia episodes and the ability to recognize and adequately manage autonomic dysreflexia has not been systematically evaluated. Aside from technical advances and accuracy, cost, convenience and patient experience must also be considered moving forward. What is not known is exactly what is meant by "clear added value" and how treatment was affected. In a smaller study of 25 patients, Pannek and Pieper (2008) had similar findings but a more useful interpretation of those findings. However, 24% of the studies done were not evaluable owing to technical problems or catheter dislocation. In a retrospective review of 71 women there were technical difficulties in 42% of the studies, with 2 being noninterpretable. Rosario and coworkers (1999) reclassified 24% of such patients as either obstructed or nonobstructed. However, Robertson and colleagues (1996) found no difference in the classification of patients with ambulatory versus conventional pressure-flow studies. In cases in which recommendations are made, these are based on the Oxford system: Grade A recommendation usually depends on consistent level 1 evidence and often means that the recommendation is effectively mandatory and placed within a clinical care pathway. Grade B recommendation usually depends on consistent level 2 and or 3 evidence studies, or "majority evidence" from randomized controlled trials. Grade C recommendation usually depends on level 4 evidence studies or majority evidence from level 2/3 studies or from expert opinion. Women with previous surgery for incontinence, a history of pelvic irradiation, pelvic surgery within the previous 3 months, and significant anterior or apical pelvic organ prolapse were excluded. The primary outcome was surgical treatment success measured as a reduction in the Urogenital Distress Inventory score from baseline to 12 months of 70% or more and a Patient Global Impression of Improvement response of "very much better" or "much better" at 12 months. Of the 578 included women, 268 women (46%) had urodynamic findings that were discordant with clinical history and physical examination.
Not only is radiation scatter minimized pregnancy vertigo ginette-35 2 mg buy low cost, but higher doses may be applied in a focal manner that effectively ablates masses in the kidney without compromising overall renal function. Treatment doses between 24 to 40 Gy resulted in complete necrosis in the treatment zone with no collateral damage to adjacent tissue. Building on this initial animal experience, Ponsky and colleagues (2007) subsequently performed a phase I study on three human patients with a mean renal tumor size of 2 cm. Patients were followed for 8 weeks, after which a partial nephrectomy was performed. Thirty patients with 82 lesions underwent treatment with varied dose/ fractionation schedules. At a median follow-up of 52 months, complete response was noted in 21% of patients, with another 58% demonstrating a partial/stable response. Local control was defined only radiologically and was estimated at 94% at 2 years. Presently its use should be considered experimental because there is no consensus for dose fractionation or technique. These fibers emit laser light that is converted to heat, achieving tissue necrosis. Results have been difficult to interpret owing to the small number of treated patients and a lack of clinical follow-up (Williams et al, 2000; Dick et al, 2002; Gettman et al, 2002b). Electroporation is a process whereby an electric field applied across cells generates nanoscale pores within cellular membranes that can be either reversible or lethally irreversible depending on the magnitude of electricity applied. With appropriate modulation it is able to ablate a substantial and reproducible amount of tissue by increasing cell membrane permeability that ultimately leads to cell death (Edd et al, 2006). The result is a nonthermal effect that preserves the extracellular matrix, tissue scaffolding, ductal structures, and large blood vessels (Edd et al, 2006; Deodhar et al, 2011). Pech and coworkers (2011) designed a phase I trial evaluating safety of the technology in six patients with tumors 2. Electrodes were placed under ultrasound guidance and delivered using cardiac synchronization. Acutely, 15 minutes after treatment ablated lesions were examined with H&E staining, which showed cellular swelling but was inadequate at assessing postablative cellular viability. The degree of tissue penetration and heat produced is related to the water content of the target tissue, which can be more difficult to predict in the heterogeneous kidney parenchyma environment (Rehman et al, 2004; Moore et al, 2010). Its use in the management of renal tumors remains investigational, with no standardized protocols for its use and with only sporadic clinical feasibility studies reported.
Urinary symptoms usually appeared within 1 to 3 years after onset of the disease and became more common with longer disease duration women's health center tucson az purchase ginette-35 2 mg visa. Nocturnal frequency tended to be the initial urinary symptom, followed by incontinence, urgency, and frequency. Urodynamic findings included decreased bladder capacity, detrusor overactivity (most common), detrusor hypocontractility, and low compliance in individual patients. SacralCoccygealTeratoma Sacral coccygeal teratoma can produce significant neurourologic dysfunction and can be associated with upper tract deterioration as a result of high-grade reflux and abnormal bladder storage pressures. Ozkan and colleagues (2006) identified 14 patients with sacral coccygeal teratoma, of whom 8 had detrusor overactivity and 2 had underactivity. Ehlers-DanlosSyndrome Ehlers-Danlos syndrome refers to a heterogeneous group of disorders characterized by inherited abnormalities of connective tissue. The main clinical manifestations are skin fragility, skin hyperextensibility, and joint mobility. More than 10 subtypes of the syndrome have been defined based on clinical, genetic, and biochemical criteria. Bladder diverticula have been associated with this disorder, with operative repair characterized by a higher recurrence rate than would ordinarily be expected. Deveaud and associates (1999) reviewed the literature on this subject and reported on one such patient with a large left-sided, nonemptying diverticulum, along with a greatly enlarged bladder capacity and high postvoid residual urine. The diverticulum enlarged with voiding, and the patient had a large postvoid residual volume. The authors thought the tissue from the nonperiureteral diverticulum was more closely related to the pathophysiology of Ehlers-Danlos syndrome, noting the tissue from that diverticulum to be more compliant. They attributed this to changes in the extracellular matrix protein caused by the EhlersDanlos syndrome. The condition is associated with deficient dietary intake (vegetarianism and old age), gut malabsorption, gastrectomy, fish tapeworm infestation, and autoimmune disorders. In a study of eight patients with this condition, multiple nonurologic symptoms were associated with the condition including ambulation problems in addition to joint spasticity. Urinary symptoms represented a mix of storage (five of eight patients), voiding (seven of eight patients), and combined dysfunctions (four of eight patients). Urodynamic evaluation revealed detrusor areflexia in two patients, neurogenic detrusor overactivity in three, and normal studies in the remainder. After treatment with vitamin B12 supplementation, detrusor areflexia improved in two patients, dysfunction improved in three patients completely, and four had partial recovery.
Syndromes
These classic categories in their usual settings are generally understood and remembered menstrual distress questionnaire order ginette-35 2 mg line, and this is why this system provides an excellent framework for teaching some fundamentals of neurogenic voiding dysfunction to students and nonurologists. Gradations of sensory, motor, and mixed lesions occur, and the patterns produced after different types of peripheral denervation/ defunctionalization may vary widely from the patterns that are classically described. Bors and Comarr (1971) made a remarkable contribution by logically deducing a classification system from clinical observation of their patients with traumatic spinal cord injury (Box 70-8). The last terms are based solely on the percentage of residual urine relative to bladder capacity. The determination of the completeness of the lesion is made on the basis of a thorough neurologic examination. The system erroneously assumes that the sacral spinal cord is the primary reflex center for micturition. The term is used in an analogy to efferent somatic nerve fibers such as those of the pudendal nerve, which originate in the same sacral cord segment but terminate directly on pelvic floor striated musculature without the interposition of ganglia. This type of lesion is characterized by involuntary bladder contraction during filling. Involuntary bladder contraction occurs during filling, but a residual urine volume of greater than 20% of the bladder capacity is left after bladder contraction, implying obstruction in the area of the bladder outlet during the involuntary detrusor contraction. This obstruction is generally due to striated sphincter dyssynergia, typically occurring in patients who are paraplegic or quadriplegic with lesions between the cervical and the sacral spinal cord. Smooth sphincter dyssynergia may be seen as well in patients with lesions above the level of T6, usually associated with autonomic hyperreflexia (see Chapter 75). Detrusor areflexia results, and whatever measures the patient may use to increase intravesical pressure during attempted voiding are insufficient to decrease residual urine to less than 10% of bladder capacity. This classification system applies best to spinal cord injury patients with complete neurologic lesions after spinal shock has passed. It is difficult to apply to patients with multicentric neurologic disease and cannot be used at all for patients with non-neurologic disease. The system fails to reconcile the clinical and urodynamic variability exhibited by patients who, by neurologic examination alone, seem to have similar lesions. The period of spinal shock that immediately follows severe cord injury is generally associated with bladder areflexia, whatever the status of the sacral somatic reflexes. Finally, although the terms balanced and imbalanced are helpful, in that they describe the presence or absence of a certain relative percentage of residual urine, they do not imply the true functional significance of a lesion, which depends on the potential for damage to the lower or upper urinary tracts and on the social and vocational disability that results. A muscular lesion can involve the detrusor itself, the smooth sphincter, or any portion, or all, of the striated sphincter. Detrusor dysfunction is the most common and generally results from decompensation following long-standing bladder outlet obstruction. Loop 1 consists of neuronal connections between the cerebral cortex and the pontine mesencephalic micturition center; this coordinates voluntary control of the detrusor reflex.
However womens health specialist appleton wi buy ginette-35 2 mg with mastercard, before a coordinated contraction, tonic inhibition of coordinated parasympathetic activity by suprapontine centers prevents bladder contraction. Additionally, ongoing pudendal nerve activation (via Onuf nucleus in the sacral cord) of the external sphincter mechanism results in the continuous resistance required to maintain continence during bladder filling. The dome of the bladder can expand well into the peritoneal cavity with relatively no extravesical force opposing this expansion. In men, this position is essentially fixed and immobile, and unless neurologic/traumatic/operative events occur, only a direct impact on the sphincteric unit itself will result in leakage. In women, where pelvic floor laxity can impact bladder neck position and function, incontinence may result, at least in part, from changes in the position of the bladder outlet. The structure of the bladder wall and characteristics of smooth muscle cells allow for passive filling without increases in pressure that would create undue forces on the bladder outlet. Relatively poor coupling between detrusor smooth muscle cells appears to contribute to the ability of the bladder to avoid the propagation of unplanned spontaneous smooth muscle contractions into a coordinated bladder contraction during filling. Although individual smooth muscle cells may be triggered to contract by stretching during bladder fill, in most situations a sustained bladder contraction requires coordinated parasympathetic stimulation. The multiple-layered mucosal lining of the bladder itself further enhances the ability of the bladder to store urine, as the urothelial cell layers ("umbrella cells") can flatten considerably with filling. Further, the extracellular matrix composition of the bladder wall, and in particular the type of collagen (type I favored in normally compliant bladders), as well as the collagen-to-elastin ratio, are critical to the maintenance of a low-pressure state in the bladder during normal filling. Urethral mucosal longitudinal folds allow for both distensibility (for opening during voiding) and contribute to the creation of a mucosal "seal" that enhances urethral closure during bladder filling. The well-vascularized spongy submucosal layer contributes to the distensibility of the urethral lumen. Additionally there are important structural and functional differences characterizing the sphincteric units in men and women that help to explain further how incontinence can be maintained in each of the sexes. Male Sphincteric Mechanisms the internal sphincter is a contributory continence mechanism extending from the bladder neck to the distal verumontanum. In the absence of disease or injury, urine commonly does not descend beyond the bladder neck to the level of the external sphincter. Dryness created by the forces at the bladder neck is, in part, a result of -adrenergic activation of smooth muscle at the bladder neck (sometimes called the lissosphincter) and within the prostatic urethra. This smooth muscle extends distally and then toward the rhabdosphincter where the greatest intraurethral forces are generated (Koraitim, 2008). Other aspects of the internal sphincter continence unit include the prostate itself, which further enhances outlet resistance.
This low dose of desmopressin melt increased mean time to first nocturnal void by 155 minutes (treatment difference vs menstruation tiredness 2 mg ginette-35 sale. There were no serum sodium drops less than 125 mmol/L or treatment withdrawals as a result of hyponatremia (Sand et al, 2013). Women appear to be more sensitive (by a factor of at least 2) to desmopressin than men in terms of effects on nocturnal urine production (Juul et al, 2011) and duration of action (Yamaguchi et al, 2013). It is hypothesized that the gene for V2 can escape inactivation that results in a higher density of V2 receptors in women and thus a greater response to desmopressin. Chapter78 Nocturia 1829 Bae and colleagues (2013) demonstrated that desmopressin is a useful treatment in men with nocturia refractory to treatment with -blockers. In summary, when considering the use of desmopressin to treat nocturia, voiding diary analysis should immediately follow a standard urologic history and physical examination. Patients with low volumes per void and no nocturnal polyuria may need nonantidiuretic treatment approaches. Current thinking is that desmopressin would be most appropriate therapy for patients with nocturia related to nocturnal polyuria. There is a gender sensitivity differential between genders (men appear to require a higher dose than women). Even though the risk for hyponatremia is less than 1% in those younger than 65 and 8% in those older than 65 years of age, it is always wise to obtain a baseline serum sodium before commencing therapy. Desmopressin should not be given to elderly patients (younger than 65 years of age) with baseline hyponatremia. It is advisable to monitor the serum sodium within 7 days and then 28 days after initial or incremental dosing, then continuing to check sodium levels every 6 months or more often as indicated. Table 78-4 presents a complete summary of medications used to treat nocturnal polyuria, including desmopressin. Additional causes of low global or nocturnal bladder capacity include learned voiding dysfunction, anxiety disorders, bladder calculi, ureteral calculi, and drugs such as xanthines (caffeine, theophylline) and -blockers (Weiss, 2012).

These afferents menopause the musical lyrics 2 mg ginette-35 order with amex, termed tension receptors, also respond to contraction of the detrusor muscle as well as tension generated by elongation during stretch and short ening during contraction. Highthreshold afferents are also likely to terminate in the deeper muscle layers or in the serosa. These mecha nosensitive endings have receptive fields (located by mechanical probing) associated with blood vessels. Thus, highthreshold affer ents respond to high levels of bladder stretch but may also become sensitized in response to inflammation. Species differences, as well as differences in nomenclature, might account for some of the variations in reported properties of bladder afferents. For example, the conduction velocity that differentiates A and C fibers is 2 m/sec in the cat, whereas it is 1. Some of the latter may be nociceptive and found to be sensitized by intravesical administration of chemicals (such as high potassium), low pH, high osmolality, and irritants such as capsaicin (Maggi et al, 1987; McMahon and Abel, 1987; Wen et al, 1994; Zagorodnyuk et al, 2009). After exposure to these substances, the sensitiv ity of bladder mechanoreceptors to distention increases, and some silent afferents become mechanoreceptive. The bladder neck and proximal urethra contain the largest density of bladder nerves (Yokokawa et al, 1985; Gabella and Davis, 1998). In the urethra, afferent nerves have been reported between the muscle fibers, surrounding blood vessels, within the urothe lium, and in a dense suburothelial plexus (Crowe et al, 1986; Tainio, 1993; Fahrenkrug and Hannibal, 1998). The striated sphinc ter muscle surrounding the urethra receives a very sparse afferent innervation that is localized primarily to nerve bundles passing between the muscle bundles. Also, studies in humans have revealed an agerelated decreased response to bladder filling in brain regions that play a role in bladder sensation (Griffiths et al, 2007). Therefore, decreased afferent sensitivity or excitability in a number of conditions in addition to normal aging may be an important factor leading to impaired voiding (Smith, 2010; Miyazato et al, 2013). Afferent nerves may extend in some species to the luminal surface of the urothelium. In contrast, the urethral epithelium is likely to be part of a signaling system involving projections of neu roendocrine cells, interstitial cells, and sensory nerve endings. There is speculation that these urethralneuroendocrine cells (often termed paraneurons) (Hashimoto et al, 1999) could release media tors such as neuropeptides or serotonin, which via activation of adjacent sensory nerves can stimulate urethral reflexes. Such types of cells are not unlike those in other types of epithelia, such as the trachea, where a cell type termed brush cells has been described, which are likely chemoreceptive and make contact with nearby sensory nerve fibers (Saunders et al, 2013). In addition, there are also reports that have identified and characterized functional prop erties of sacral afferents responding to flow through the urethra (Snellings et al, 2012). These are important observations whereby properties of these flowresponsive afferents seem to parallel those of cutaneous afferents.
Jose, 49 years: Another 5- or 10-mm trocar is placed about two fingerbreadths above the iliac crest near the anterior superior iliac spine. This is a rare symptom and only exists when there is a fistula, for example a prostate-rectal fistula. Second, they can sensitize endings without causing direct stimulation but causing hyperexcitability to other chemical and mechanical stimuli. Its urologic use for the treatment of detrusor striated sphincter dyssynergia was first reported by Dykstra and colleagues (Dykstra and Sidi, 1990; Dykstra et al, 1998, 2003).
Larson, 65 years: It is important to avoid injury to the ascending mesocolon, since injury to the right colic and ileocolic arteries may devitalize this segment of colon. Short-term outcomes at mean follow-up of 12 months were not different between the two groups, including positive margin rate, local recurrence, and metastasis. Radiographic differentiation between metabolically functional and nonfunctioning adenomas has been investigated, and, to date, no reliable radiographic test or characteristic is sensitive enough to obviate endocrinologic evaluation based solely on imaging (Korobkin et al, 1996b; Fujiyoshi et al, 2003; Hussain and Korobkin, 2004). Urgency is the complaint of a sudden compelling desire to void that is difficult to defer.
