The aim of this study was to use a systematic schedule, including urodynamics, to describe the rate of coexisting overactive bladder (OB) in patients with bladder outlet obstruction (BOO) caused by benign prostatic hyperplasia (BPH). We also identified differences between the patients with pure BOO compared with those with BOO combined with OB (BOO + OB).(More)
The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied(More)
OBJECTIVES To estimate the relationship between age and the values of different diagnostic tests in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic enlargement (BPE) and to compare prostate growth curves between the normal population sample, healthy men and men with LUTS. MATERIAL AND METHODS A series of 354 men (mean age 70.2(More)
OBJECTIVE An essential part of investigation of the lower urinary tract is pressure/flow studies (pQS). In fact, pQS is the only way of diagnosing bladder outlet obstruction. There is controversy regarding whether or not prophylactic antibiotic treatment is necessary. This prospective study was carried out in order to determine the frequency of infections(More)
To study home uroflowmetry and to compare this method to free or "traditional" uroflowmetry in the evaluation of the patient with symptomatic benign prostatic hyperplasia (BPH), and the relationship between the values of home uroflowmetry parameters and bladder outlet obstruction (BOO). Twenty-five patients (mean age, 67 years) with symptomatic BPH were(More)
INTRODUCTION PRIMARY OBJECTIVE to investigate if 30-MINUTES-TUMT can be performed under topical anesthesia and analgesics. SECONDARY OBJECTIVES to evaluate retrospectively analgesics and to study parameters connected with pain. MATERIALS AND METHODS Eighty-nine patients underwent TUMT. Patients were divided into four groups with different(More)
OBJECTIVE For patients with the combination of severe bladder outlet obstruction (BOO) and severe overactive bladder (OB), no straightforward and safe treatment exists due to the risk of urge incontinence after TURP. In this study we have used a biodegradable polyglycolic stent to simulate the status after TURP and register the risk for urge incontinence.(More)
PURPOSE To evaluate the durability of the effect of transurethral microwave thermotherapy (TUMT) for lower urinary-tract symptoms (LUTS) suggestive of bladder outlet obstruction (BOO). PATIENTS AND METHODS A total of 841 patients with LUTS received TUMT using the Prostatron device at Sahlgrenska University Hospital, Sweden. Two treatment programs were(More)
PURPOSE OF REVIEW Endoprosthesis has been used to maintain luminal patency in several different diseases and is well established in cardiovascular and gastrointestinal pathologies. The usefulness and application in prostatic pathology and benign prostatic hyperplasia are not as clear. This report reviews the development of overactive bladder in patients(More)
OBJECTIVE To investigate the prevalence of and restrictions in various parts of daily life due to lower urinary tract symptoms (LUTS) in an unselected Swedish male population. MATERIAL AND METHODS A random selection of 3345 men throughout Sweden, aged between 41 and 80, was contacted by telephone and evaluated according to International Prostate Symptom(More)
