Prostate cancer, bladder cancer, and pelvic floor weakness are among the most common diseases of the pelvis. Cardinal symptoms include painless macrohematuria in bladder cancer and urinary and fecal incontinence in pelvic floor weakness. Suspicion of prostate cancer currently is most frequently raised when the serum concentration of prostate-specific antigen is pathologically elevated. Besides extensive clinical and invasive diagnosis, clinical imaging is frequently applied for the localization, locoregional staging, and diagnosis of recurrence of prostate cancer and invasive bladder cancer, and in clinically difficult cases of cystocele, enterocele, rectocele, descensus or prolapse of vagina, uterus, and rectum, and rectal intussusception. Magnetic resonance imaging with T2-weighted TSE or FSE images in several planes combined with either axial, T1-weighted images and MR spectroscopy for the prostate, dynamic contrast-enhanced T1-weighted images for the urinary bladder, or dynamic T2-weighted functional images for pelvic floor incontinence are particularly well suited as clinical imaging methods.

*Urinary incontinence in males is gaining increasingly more attention. *Male urinary incontinence can be classified as storage incontinence due to overactive bladder syndrome or stress incontinence due to urethral sphincter dysfunction. *Most patients benefit from the currently available treatment options for overactive bladder, which include physiotherapy, medication, botulinum A toxin injections and neuromodulation techniques. *The number of radical prostatectomies performed for prostate cancer is increasing; this intervention can lead to stress incontinence due to sphincter weakness. *Various treatment options are available for stress incontinence due to sphincter weakness. *In addition to physiotherapy, treatment options also include the artificial urinary sphincter, which has been available for decades. *New treatments include para-urethral balloons and male slings. The value of these approaches must be proven in the coming years.

It is well-established that total testosterone (TT) in men decreases with age and that bioavailable testosterone (bio-T) falls to an even greater extent. The clinical relevance of declining androgens in the aging male and use of testosterone replacement therapy (TRT) in this situation is controversial. Most studies have been short term and there are no large randomized placebo-controlled trials. Testosterone has many physiological actions in: muscles, bones, hematopoietic system, brain, reproductive and sexual organs, adipose tissue. Within these areas it stimulates: muscle growth and maintenance, bone development while inhibiting bone resorption, the production of red blood cells to increase hemoglobin, libido, enhanced mood and cognition, erectile function and lipolysis. Anabolic deficits in aging men can induce: frailty, sarcopenia, poor muscle quality, muscle weakness, hypertrophy of adipose tissue and impaired neurotransmission. The aging male with reduced testosterone availability may present with a wide variety of symptoms which in addition to frailty and weakness include: fatigue, decreased energy, decreased motivation, cognitive impairment, decreased self-confidence, depression, irritability, osteoporotic pain and the lethargy of anemia. In addition, testosterone deficiency is also associated with type-2 diabetes, the metabolic syndrome, coronary artery disease, stroke and transient ischemic attacks, and cardiovascular disease in general. Furthermore, there are early studies to suggest that TRT in men with low testosterone levels may improve metabolic status by: lowering blood sugar and HbA1C in men with type-2 diabetes, reducing abdominal girth, ameliorating features of the metabolic syndrome, all of which may be protective of the cardiovascular system. The major safety issue is prostate cancer but there is no evidence that supports the idea that testosterone causes the development of a de novo cancer. So on balance in a man with symptoms of hygonadism and low or lowish levels of testosterone with no evidence of prostate cancer such as a normal PSA a therapeutic (4-6 months) trial of TRT is justified. Treatment and monitoring of this duration will determine whether the patient is responsive.

A 61-year-old man who had been diagnosed with prostate cancer 9 years ago and had been treated with pelvic irradiation and intermittent androgen deprivation therapy visited the emergency room because of back pain and weakness in both legs. Spine magnetic resonance imaging showed a lumbar epidural mass and spine metastasis. The whole-body workup revealed multiple metastases to the lymph nodes, bone, liver, and lung. The serum prostate-specific antigen was 0.02 ng/ml. He underwent laminectomy, posterior fixation, and epidural mass excision, and metastatic adenocarcinoma from the prostate was diagnosed. The patient underwent 1 cycle of docetaxel-based chemotherapy. More chemotherapy could not be done because of his general weakness. The patient died one month later of multiple organ failure.

The majority of male urinary incontinence seen is secondary to sphincter weakness following prostatic surgery. As there is a rising elderly population and increasing numbers of surgical interventions for prostate cancer, incidence of male incontinence is increasing. Hence, management of male incontinence has become a subject of increased interest for urologists. Various non-surgical and surgical approaches have been suggested for this devastating condition. Non-invasive therapies are suggested for early postoperative and mild incontinence. For surgical treatment the artificial urinary sphincter is still labeled the gold standard despite the introduction of several more minimally invasive treatments. However, as yet there is no consensus on the optimal timing and best modality for managing these men. Well designed, centrally funded clinical trials are required to establish which treatment modality to offer and when in the broad spectrum of male incontinence. This review focuses mainly on the management of post-prostatectomy incontinence since the management of other types varies little from the modalities of treatment in women.

A 69-year-old man with prostate cancer underwent surgery for 16 h. Approximately 6 h after surgery, the patient developed severe pain and motor weakness in his right arm. After neurologic examinations that included a nerve conduction study and electromyography, the patient was diagnosed with a brachial plexus injury. The causes of the brachial plexus injury were thought to be abduction of both arms, direct compression of the shoulder brace, and prolonged surgery. Most of the postoperative peripheral nerve injuries due to patient position are preventable, and anesthetists and surgeons should be very careful in positioning the patient accurately.

The latest EAU guidelines on the evidence based-management of prostate cancer (P.Ca.), with regard to pharmacological androgen deprivation therapy (ADT), reiterate that the primary objective of hormonal therapy is to slow down the progression of the disease to the greatest possible extent. Degarelix a new product for the treatment of hormone-dependent P.Ca. has recently become available in Italy. This product is classified as a GnRH antagonist and provides safe and effective ADT. It completely blocks the synthesis and release of gonadotropins (LH and FSH), thus rapidly reducing the testosterone levels without causing clinical flare. The results of the clinical trials (36 months) demonstrate that degarelix, compared to high-dose leuprorelin (7.5 mg), suppresses levels of testosterone and PSA (Prostate-Specific Antigen) more rapidly and reduces levels of FSH and musculoskeletal events associated with treatment (pain, muscle weakness, spasms, oedema/joint stiffness, arthralgia, osteoporosis and osteopoenia) to a greater extent. In addition, these results demonstrate a significant increase in the probability of PSA progression-free survival, suggesting a possible delay in the onset of the "castration-resistant" stage. The information available to date supports the use of this new molecule as a valid alternative to GnRH agonists in the treatment of hormone-sensitive P.Ca.

A 59-year-old male presented to the emergency department with a four-month progressive history of proximal muscle pain and weakness with elevated erythrocyte sedimentation rate and C-reactive protein. He was initially diagnosed with polymyalgia rheumatica (PMR) and admitted to the hospital. During his hospitalization he was found to have metastatic prostate cancer, which was thought to be responsible for his PMR-like syndrome. By recognizing the resemblance between metastatic malignancy and rheumatologic diseases, the emergency physician can improve diagnostic accuracy.

The American Cancer Society estimates that in 1991 over seven million Americans were alive despite a diagnosis of cancer.1 As the medical community becomes more successful in prolonging the lives of cancer patients, a significant number will experience the resultant disability of cancer and its treatment. Those with advanced disease may find the quality of their lives to be profoundly compromised. The role of rehabilitation with the latter population is to maximize the patients' functional capabilities and to conserve their limited energy reserves. Clearly, quality of life is an overriding issue fix this population.The development of bony metastases is devastating for the cancer patient and presents a considerable challenge for the physical therapist. Approximately 50% of patients with breast, lung, or prostate cancer will develop bony metastases. Less common, though equally problematic, are bone metastases in patients with carcinoma of the kidney, pancreas, bladder, thyroid, and cervix.Patients with advanced disease present a complex clinical picture. It is imperative that the physical therapist consult and confer regularly with the oncologist, physiatrist, and/or orthopedist to remain abreast of the patient's changing clinical picture. Information vital to safe and effective rehabilitation includes the presence, location, and extent of bony metastases, involvement of bone marrow potentiating refractory pancytopenia, infection, and hypercalcemia secondary to prolonged immobility.In patients with metastatic disease to bone, it is not sufficient to rely solely on plain X-ray findings. Plain radiographs will not detect bone lesions unless a sufficient amount of matrix is destroyed (30-50% of bone matrix must be involved to be visualized). Bone scan results should be assessed prior to establishing a rehabilitation program for most cancer patients. Patients with advanced disease frequently present with pain, neurologic deficits, impending or pathologic fractures, and generalized weakness associated with prolonged immobility. Any new complaints of pain, or findings of progressive weakness should be discussed with the patient's physician in order to initiate an appropriate work-up.

Prostate cancer (PCa) screening has been substantially influenced by the clinical implementation of serum prostate-specific antigen (PSA). In this context, improvement of early PCa detection and stage migration as well as reduced PCa mortality were achieved, and up-to-date PSA represents the gold standard biomarker of PCa diagnosis together with clinical findings. Nonetheless, PSA shows weakness in discriminating between malign and benign prostatic disease or indolent and aggressive cancers. As a result, the expansion of PSA screening is extensively debated with regard to overdetection and ultimately overtreatment, keeping in mind that PCa is still the third leading cause of cancer-specific mortality in the Western male population. Consequently, today's task is to increase the accuracy of PCa detection and furthermore to allow stratification for indolent PCa that might permit active surveillance and to filter out aggressive cancers necessitating treatment. Thus, novel biomarkers, especially in combination with approved clinical risk factors (e.g., age or family history of PCa), within multivariable prediction models carry the potential to improve many aspects of PCa diagnosis and to enable risk classification in clinical practice. Multivariable models lead to superior accuracy for PCa prediction instead of the use of a single risk factor. The aim of this article was to present an overview of known risk factors for PCa together with new promising blood- and urine-based biomarkers and their application within risk models that may allow risk stratification for PCa prior to prostate biopsy. Risk models may optimize PCa detection and classification with regard to improved PCa risk assessment and avoidance of unnecessary prostate biopsies.
