Background: Spinal local anesthetics interrupt the micturition reflex; bladder function remains impaired until sensory block had regressed to the S3 segment. Intrathecal opioids cause dose-dependent suppression of detrusor contractility. We studied the effects of spinal anesthesia with a combination of lidocaine and sufentanil on lower urinary tract function.

Objectives: To investigate the information of voiding data in relation to symptoms and well-being in men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) and to compare this information with that of prostate volume (Vprostate), maximal free urinary flow rate (Q(max,free)), and obstruction grade (OG).

Methods: We performed mandatory tests, recommended tests, and pressure-flow studies in 384 consecutive men with LUTS suggestive of BPH. We estimated nocturia, diuria, and mean voided volume (Vmean) from their voiding diaries.

Objectives: Although in many cases of penile carcinoma, laser therapy has become the standard treatment, opinion still differs regarding the risks related to the relatively high rate of recurrence that accompanies this form of treatment. In this study, we reviewed the results of neodymium:yttrium-aluminum-garnet laser treatment of 44 consecutive patients with penile carcinoma in our institution from 1986 to 2003.

Methods: We created five groups, on the basis of the T stage and grade of the tumor.

Objectives: To investigate the contribution of urodynamically proven presence or absence (International Continence Society classification) of bladder outlet obstruction (BOO) to treatment recommendations for lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia, and to investigate the impact of the replacement of the invasively estimated BOO classification with the noninvasively assessed BOO probability on treatment recommendations.

Methods: Mandatory tests, recommended tests, and pressure-flow studies (with BOO classification) were performed in 150 consecutive men with LUTS suggestive of BPH. Three experienced urologists proposed, independently of each other, the treatment for each patient: watchful waiting, pharmacologic treatment, or surgery.

Nevi and melanomas correlate to childhood and intermittent solar UV exposure, xeroderma pigmentosum patients run increased risk, and p16(Ink4a) expression is often lost in malignant progression. To ascertain the effect of these risk factors, pigmented hairless Ink4a/Arf-, Xpa- knockout mice were subjected to various combinations of neonatal [7,12-dimethylbenz(a)anthracene (DMBA) or UVB exposure] and adult treatments (12-O-tetradecanoylphorbol-13-acetate or subacute daily UVB exposure or intermittent overexposure). Nevi occurred earliest, grew largest, and were most numerous in mice exposed to DMBA followed by intermittent UVB overexposure [effect of six minimal edemal doses (MED), 1 x /2 weeks > 4 MED 1 x /wk].
