Notificación y clasificación de complicaciones después de procedimientos quirúrgicos urológicos: una evaluación y recomendaciones del panel de guías clínicas de la EAU
No full textContext: The incidence of postoperative complications is still the most frequently used surrogate marker of quality in surgery, but no standard guidelines or criteria exist for reporting surgical complications in the area of urology.
Objective: To review the available reporting systems used for urologic surgical complications, to establish a possible change in attitude towards reporting of complications using standardised systems, to assess systematically the Clavien-Dindo system when used for the reporting of complications related to urologic surgical procedures, to identify shortcomings in reporting complications, and to propose recommendations for the development and implementation of future reporting systems that are focused on patient-centred outcomes.
Evidence acquisition: Standardised systems for reporting and classification of surgical complications were identified through a systematic review of the literature. To establish a possible change in attitude towards reporting of complications related to urologic procedures, we performed a systematic literature search of all papers reporting complications after urologic surgery published in European Urology, Journal of Urology, Urology, BJU International, and World Journal of Urology in 1999-2000 and 2009-2010. Data identification for the systematic assessment of the Clavien-Dindo system currently used for the reporting of complications related to urologic surgical interventions involved a Medline/Embase search and the search engines of individual urologic journals and publishers using Clavien, urology, and complications as keywords. All selected papers were full-text retrieved and assessed; analysis was done based on structured forms.
Evidence synthesis: The systematic review of the literature for standardised systems used for reporting and classification of surgical complications revealed five such systems. As far as the attitude of urologists towards reporting of complications, a shift could be seen in the number of studies using most of the Martin criteria, as well as in the number of studies using either standardised criteria or the Clavien-Dindo system. The latter system was not properly used in 72 papers (35.3%).
Conclusions: Uniformed reporting of complications after urologic procedures will aid all those involved in patient care and scientific publishing (authors, reviewers, and editors). It will also contribute to the improvement of the scientific quality of papers published in the field of urologic surgery. When reporting the outcomes of urologic procedures, the committee proposes a series of quality criteria
Prostate cancer nomograms: an update
No full textObjective: Several nomograms have been developed to predict outcomes related to prostate cancer (PCa). Methods: We provide a descriptive and an analytic comparison of nomograms. Further, we report a set of recent PCa nomograms, in which we recorded predictor variables, number of patients used to develop each nomogram, and nomogram-specific features. Moreover, accuracy estimates and type of validation are considered. Results: Our findings suggest a demand for updated nomograms in selected fields of PCa outcomes. Moreover, an increasing number of nomograms address important end points such as prostate-specific antigen recurrence, distant metastases, or androgen-independent PCa-specific survival. Conclusion: Our results suggest that nomograms are available for many PCa-related outcomes. They represent a valid methodologic approach if correct criteria are met.

Body mass index does not predict prostate-specific antigen or percent free prostate-specific antigen in men undergoing prostate cancer screening
No full textObjectives: Body mass index (BMI) may alter serum prostate specific antigen (PSA) and percent free PSA (%fPSA) and may mask the risk of prostate cancer. We investigated the relationship between BMI and PSA or %fPSA. Materials and methods: Height, weight, PSA and %fPSA were assessed in 616 consecutive screened men without prostate cancer. Continuously coded and categorised BMI was studied. Statistical analyses consisted of ANOVA, linear regression, bivariate and partial correlations. Results: Median age was 57 years. Median PSA was 1.0 and median %fPSA was 26. Median BMI was 25.8 kg/m(2). Neither continuously coded nor categorised BMI correlated with either PSA or %fPSA in unadjusted or age-adjusted analyses (all p values >= 0.3). Conclusions: Body mass index does not affect PSA or %fPSA in men without known prostate cancer, who undergo prostate cancer screening. Therefore, PSA or %fPSA-based screening or early detection efforts do not require an adjustment for BMI. (c) 2007 Elsevier Ltd. All rights reserved
PSA - Quo vadis?
No full textProstate cancer is the most frequent cancer in males. Because of the high cure rates, early detection of prostate cancer should identify organ-confined prostate cancers. An early detection examination should be performed annually starting at the age of 50 years and ending when life expectancy is less than 10 years. Digital rectal examination is supplemented by determination of prostate-specific antigen (PSA). Before the first PSA test, the patient must be informed of possible consequences such as biopsy recommendation and treatment options. A threshold of 4 ng/ml is defined as the indication for prostate biopsy. Imaging methods do not play a major role in early detection of prostate cancer today. Early detection identifies many latent prostate cancers, and patients may receive overtreatment. A possible solution is to change the early detection paradigm from detection of all prostate cancers to identification of aggressive ones. In this article, early detection is discussed based on the recent literature
Positive Surgical Margins After Radical Prostatectomy: A Systematic Review and Contemporary Update.
No full textCONTEXT: The clinical significance of positive surgical margins (PSMs) in radical prostatectomy (RP) specimens and the management of affected patients remain unclear.
OBJECTIVE: To address pitfalls in the pathologic interpretation of margin status; provide an update on the incidence, predictors, and long-term oncologic implications of PSMs in the era of robot-assisted laparoscopic RP (RALRP); and suggest a practical evidence-based approach to patient management.
EVIDENCE ACQUISITION: A systematic review of the literature was performed in April 2013 using Medline/PubMed, Web of Science, and Scopus databases and the Cochrane Database of Systematic Reviews. Studies focusing on PSMs in RP pertinent to the objectives of this review were included. Particular attention was paid to publications within the last 5 yr and those concerning RALRP.
EVIDENCE SYNTHESIS: A total of 74 publications were retrieved. Standardized measures to overcome variability in the pathologic interpretation of surgical margins have recently been established by the International Society of Urological Pathology. The average rate of PSMs in contemporary RALRP series is 15% (range: 6.5-32%), which is higher in men with a more advanced pathologic stage and equivalent to the rate reported in prior open and laparoscopic prostatectomy series. The likelihood of PSMs is strongly influenced by the surgeon's experience irrespective of the surgical approach. Technical modifications using the robotic platform and the role of frozen-section analysis to reduce the margin positivity rate continue to evolve. Positive margins are associated with a twofold increased hazard of biochemical relapse, but their association with more robust clinical end points is controversial. Level 1 evidence suggests that adjuvant radiation therapy (RT) may favorably affect prostate-specific antigen recurrence rates, but whether the therapy also affects systemic progression, prostate cancer-specific mortality, and overall survival remains debatable.
CONCLUSIONS: Although positive margins in prostate cancer are considered an adverse oncologic outcome, their long-term impact on survival is highly variable and largely influenced by other risk modifiers. Adjuvant RT appears to be effective, but further study is required to determine whether early salvage RT is an equivalent alternative
Prevention and Management of Postprostatectomy Sexual Dysfunctions Part 2: Recovery and Preservation of Erectile Function, Sexual Desire, and Orgasmic Function
No full textContext: Sexual dysfunction is common in patients who undergo radical prostatectomy (RP) for prostate cancer (PCa). Objective: Review the available literature concerning prevention of, and management strategies for, post-RP sexual dysfunction in terms of postoperative treatments for erectile function (EF), sexual desire (SD), and orgasmic function (OF) impairment. Evidence acquisition: A literature search was performed using Google and PubMed databases for English language original and review articles either published or e-published up to November 2011. Evidence synthesis: We propose a rational description of many of the clinically available preventive and therapeutic strategies for the preservation and recovery of post-RP EF. A huge amount of preclinical data show that tissue damage ultimately leads to structural alterations, and the literature stresses that rehabilitation and treatment are undoubtedly better than leaving the erectile tissue to its unassisted fate; likewise, the timing of any rehabilitation and treatment is of major clinical importance. However, no specific recommendation emerges regarding the structure of the optimal rehabilitation or treatment regimen. The role of postoperative erectile dysfunction (ED) treatment of those patients who received a non-nerve-sparing RP was also extensively discussed. The literature almost completely lacks a systematic and comprehensive debate about SD (ie, low libido) and OF (ie, decreased intensity of orgasm, dysorgasmia, and climacturia) in patients undergoing RP. Psychological and sexual counseling is of major importance to improve any rehabilitation and treatment of postoperative EF, SD, and OF impairment. Conclusions: Despite the great number of possible rehabilitation approaches proposed, these approaches should be considered only as strategies, since incontrovertible evidence of their effectiveness for improving natural EF recovery is limited. Conversely, numerous effective therapeutic options are available for treating post-RP ED. SD and OF have not yet been fully assessed in patients who underwent RP.

Problems, objective, and substance of early detection of prostate cancer
No full textThe current S3 guideline for early detection of prostate cancer initiates a change to the paradigm in early detection from the detection of all prostate cancers to the identification of aggressive prostate cancers. Early detection is performed annually and starts at the age of 40 years; it should be terminated at a life expectancy of less then 10 years. The choice of the frequency of early detection should be risk adapted. The digital rectal examination is supplemented by determination of PSA. Previous to the first PSA test the patient has to be informed concerning possible consequences such as biopsy recommendation and treatment options. A threshold of 4 ng/ml is defined as an indication for prostate biopsy for the first administration. In the following early detections the PSA velocity should be considered. Today imaging methods do not play a major role in early detection of prostate cancer. Early detection identifies many latent prostate cancers and patients may receive overtreatment. The recent S3 guideline for early detection is discussed against this background on the basis of the recent literature
