'Lower urinary tract symptoms' is a term that describes symptoms related to both the storage and emptying phases of the micturition cycle. Storage symptoms include urinary frequency urgency, urge incontinence, nocturia, dysuria and other kinds of pain emanating from the bladder or urethra. Emptying symptoms consist of hesitancy, straining to void, difficulty starting, diminished stream, a feeling of incomplete bladder emptying and urinary retention. In both sexes, the etiology of lower urinary tract symptoms is multifactorial, and symptoms are a poor indicator of underlying pathophysiology. In men, lower urinary tract symptoms are most often attributed to prostatic obstruction, but only approximately two-thirds of men with lower urinary tract symptoms meet the accepted diagnostic criteria for obstruction. Approximately half have detrusor overactivity and a smaller number have impaired detrusor contractility, sensory urgency, sphincteric incontinence, polyuria or nocturnal polyuria. In women, lower urinary tract symptoms are often considered to result from hormonal abnormalities, childbirth, aging, or previous surgery, but the multifactorial underlying pathophysiology is similar to that seen in men, except for a much lower incidence of urethral obstruction and a high incidence of sphincteric incontinence. Treatment typically begins with empiric, conservative therapies aimed at resolving detrusor instability or bladder outlet obstruction. However, although either or both of these etiologies may exist in the individual with lower urinary tract symptoms, treatment may fail as a result of another cause. We believe that treatment based on the pathophysiology of the symptoms will lead to better outcomes than treatment based on symptoms alone.

Lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH), and sexual dysfunction, are common, highly bothersome conditions in older men, and the prevalence of both disorders increases with age. Sexual dysfunction manifests mainly as erectile dysfunction (ED), ejaculatory disorders, or decreased libido/hypoactive sexual desire (HSD). Whereas both reduced rigidity and reduced ejaculate volume are highly prevalent in ageing men, reduced rigidity and pain on ejaculation are considered to be most bothersome. Sexual dysfunction is much more prevalent in patients with LUTS/BPH than in men with no LUTS/BPH, even after controlling for confounding variables such as age or comorbidities. Hence LUTS/BPH is considered an independent risk factor for sexual dysfunction. Whether this is because of a common underlying pathology, or whether the considerable bother associated with LUTS/BPH leads to reduced sexual functioning, remains to be elucidated. Despite a decline in the frequency of sexual intercourse, as well as in overall sexual functioning, most ageing men report regular sexual activity and consider their sex life as an important dimension of their quality of life (QoL). However, most patients with LUTS/BPH experience a negative effect of their LUTS on their sex life. Hence, treatment of LUTS/BPH should aim to at least maintain or, if possible, improve sexual function. Current medical treatment of LUTS/BPH consists of monotherapy with alpha1-adrenoceptor (AR) antagonists, 5alpha-reductase inhibitors (RIs) or a combination of these. Whereas 5alpha-RIs increase the risk of ED, ejaculatory disorders and HSD, alpha1-AR antagonists can induce ejaculatory disorders, but do not provoke HSD or ED. Combined therapy carries the cumulative risk for sexual dysfunction associated with either type of drug. As already indicated, ED is generally perceived as more bothersome than ejaculatory disorders. In addition, alpha1-AR antagonists slightly improve overall sexual function, possibly by increasing blood flow in the penis through alpha1-AR blockade and/or to an increased overall QoL from the relief of LUTS. It can be concluded that alpha1-AR antagonists constitute a first-line therapy for LUTS/BPH because they combine good treatment efficacy with very few adverse effects on sexual function.

To assess efficacy of magnetolaser therapy (KAP-ELM-01 Andro-Gin unit) in the treatment of inflammatory chronic abacterial prostatitis (ICAP), 68 ICAP patients were divided into 2 groups. Group 1 patients (n = 33) received standard therapy. Group 2 patients received standard therapy plus magnetolaser (ML) therapy. The effect was assessed by the symptoms scale and indices of kallirrein-kinin system. After treatment pain relieved by 36,9%, on the average, in group 1 and by 63.1% in group 2. Lower urinary tract symptoms regressed insignificantly in both groups: by 4.8% and 7.1%, respectively. Quality of life improved by 27.6 and 65.5%, respectively. Kallikrein activity in prostatic secretion remained high in both groups. A 21.7% rise (p < 0.05) of prokallikrein level was seen after treatment only in group 2. Activity of KKS inhibitors (alpha2-MG and alphal-PI) in prostatic secretion normalized in group 2. Total activity of serin proteinases lowered in both groups (p < 0.05). High activity of alphal-PI (8.21 + 1.97 U/ml) persisted in group 1. Thus, standard treatment of ICAP does not result in biochemical normalization of prostatic secretion. ML therapy is more effective.

Ketamine was discovered in the 1960s and released for public use in 1970. Originally developed as a safer alternative to phencyclidine, ketamine is primarily used in clinical settings for analgesia and sedation. In recent years, other uses have been developed, including pain management and treatment of asthma and depression. Clinical use of ketamine causes dissociation and emergence delirium. These effects have led to recreational abuse. Although death from direct pharmacologic effects appears rare, the disinhibition and altered sensory perceptions caused by ketamine puts users at risk of environmental harm. Ketamine has also been implicated in nonconsensual sexual intercourse. Data continue to build that chronic ketamine use may lead to morbidity. Impairment of memory and persistent dissociative, depressive, and delusional thinking has also been reported with long-term use. Lower urinary tract symptoms, including cystitis have been described. Gastric and hepatic pathology have also been noted, including abnormal liver function tests, choledochal cysts and dilations of the common bile duct. S-ketamine, an enantiomer in racemic ketamine, has been shown to be hepatotoxic in vitro. Abstinence from ketamine may reduce the adverse effects of chronic use and is considered the mainstay of treatment. Specialized urine drug testing may be required to detect use, as not all point of care urine drug screens include ketamine.

Lower urinary tract symptoms (LUTS) are a common complaint in the general population with great impact on the quality of life. Besides the classical pathologies, there are less common causes that must be considered in the treatment approach for patients with LUTS. We present the case of a 30-year-old patient with multiple emergency department episodes with dysuria, urinary frequency, suprapubic pain and an episode of acute urinary retention. The blood and urine tests only revealed increased systemic inflammatory parameters. The ultrasound examination showed thickening of the bladder wall, and the CT scan revealed a retropubic abscess originating from a pubic symphysis osteomyelitis. A percutaneous drainage was performed and, after empirical antibiotic therapy, there was complete resolution of the clinical picture.
