INTRODUCTION: In recent years, the surgical technique for open radical prostatectomy has evolved and increasing attention is paid to preserving anatomic structures and the impact on outcome and quality of life. METHODS: Technical aspects of nerve-sparing open radical retropubic prostatectomy (RRP) are described. Patient selection criteria and functional results are discussed, focusing on postoperative urinary continence. RESULTS: The video demonstrates the nerve-sparing open RRP and important steps are elucidated with schematic drawings. The value of nerve sparing, not only for preserving erectile function, but also for preserving urinary continence is discussed and results from our institution are presented. In our series, urinary incontinence was present in 1 of 71 patients (1%) with attempted bilateral nerve-sparing, 11 of 322 (3%) with attempted unilateral nerve-sparing, or 19 of 139 (14%) without attempted nerve-sparing surgery. In multiple logistic regression analysis, the only statistically significant factor influencing urinary continence after open RRP was attempted nerve sparing (odds ratio, 4.77; 95% confidence interval, 2.18-10.44; p=0.0001). CONCLUSIONS: Nerve-sparing surgery has a significant impact on erectile function and urinary continence and should be performed in all patients provided radical tumour resection is not compromised. For successful nerve preservation we advocate a lateral approach to the prostate to improve visualisation and simplify separation of the neurovascular bundles from the dorsolateral prostatic capsule. Bunching, ligating, and incising Santorini's plexus over the prostate and not over the sphincter ensures a bloodless surgical field. Mucosa-to-mucosa adaptation of the reconstructed bladder neck and the urethra is another important factor to be observed.
We searched for population-based cross-sectional studies, cohort studies and randomized controlled trials (RCTs) on erectile dysfunction (ED) through Medline, PubMed, PsychInfo and scanned though reference lists. Studies that did not include adjusted odds ratios (OR) of physical activity were excluded. Seven cross-sectional studies were suitable for meta-analysis, and the results from one cross-section study, two cohort studies and one RCT were summarized. Pooling the ORs using random effects models, we derived summary estimate for adjusted OR of physical activity in those with ED compared with those without ED, which was 0.53 (0.31, 0.91). Moderate and high physical activities were associated with a lower risk of ED, with ORs at 0.63 (0.43, 0.93) and 0.42 (0.22, 0.82), respectively. Funnel plot by visual inspection, and Begg's test and Egger's test did not detect significant publication bias. Sensitivity analyses revealed that the summary estimate from the random effects model was robust to changes in study sample size and level of statistical adjustment, but not so robust to changes in ED definition, although the summary estimate for each ED definition did not differ significantly. Although causality cannot be demonstrated from cross-sectional studies, the apparent 'protective' effect of physical activity on ED should be further investigated using large-scale cohort studies or RCTs.
In a consecutive series of 1140 male subjects reporting a stable couple relationship and different degrees of sexual dysfunction, we evaluated the impact of relational factors, as assessed by the Structured Interview on Erectile Dysfunction (SIEDY) Scale 2 (exploring, as reported by the patient, menopausal symptoms, partner's medical illness interfering with sexual activity, and reduced partner desire and climax). We found that the SIEDY Scale 2 is significantly and independently associated with erectile dysfunction (ED), delayed ejaculation, hypoactive sexual desire, and decreased frequency of intercourse. SIEDY Scale 2 scores are associated with an advanced age of the partner and a long couple relationship, independently from patient's age. In addition, an increased relational factor correlates with increased extramarital affairs, conflicts in the couple, alcohol abuse, and presence of depressive symptoms, as assessed by the Middlesex Hospital Questionnaire. Our results should encourage the andrologist to consider the context in which sexual symptoms develop, analyzing the relationship and partner's behaviors and diseases. Resolving, or at least ameliorating, the relational background and the sexual framework might help in treating male sexual dysfunction.
