Abstract
Radical cystectomy (RC) is the standard treatment for nonmetastatic muscle-invasive urothelial carcinoma of the urinary bladder. It is associated with relevant morbidity and mortality. After RC, the 5‑year overall survival rate is approximately 60%. In the context of the present work, quality parameters of RC divided into oncological/functional criteria and freedom from complications are identified and summarized. A PubMed search was performed. In addition to early criteria such as negative surgical margins, performance of pelvic lymphadenectomy, creation of a continent urinary diversion or preservation of sexual function, long-term criteria were identified such as the absence of higher-grade postoperative complications, recurrence-free survival and the preservation of health-related quality of life. The early criteria are suitable for individualized therapy planning, whereas the long-term criteria can be used for quality monitoring.

Abstract
PURPOSE To determine whether the fusion of multiparametric magnetic resonance imaging (MRI) with transrectal real-time elastography (RTE) improves the visualization of PCa lesions compared to MRI alone. MATERIALS AND METHODS In a prospective setting, 45 patients with biopsy-proven PCa received prostate MRI prior to radical prostatectomy (RP). T2 and diffusion-weighted imaging (T2WI/DW-MRI) and, if applicable, dynamic contrast-enhanced sequences (T2WI/DW/DCE-MRI) were used to perform MRI/RTE fusion. The probability of PCa on MRI was graded according to the PI-RADS score for 12 different prostate sectors per patient. MRI images were fused with RTE to stratify suspicious from non-suspicious sectors. Imaging results were compared to whole mount sections using nonparametrical receiver operating characteristic curves and the area under these curves (AUC). RESULTS 41 of 45 patients were eligible for final analyses. Histopathology confirmed PCa in 261 (53%) of 492 prostate sectors. MRI alone provided an AUC of 0.62 (T2WI/DW-MRI) and 0.65 (T2WI/DW/DCE-MRI) to predict PCa and was meaningfully enhanced to 0.75 (T2WI/DW-MRI) and 0.74 (T2WI/DW/DCE-MRI) using MRI/RTE fusion. Sole MRI showed a sensitivity and specificity of 57.9% and 61% with the best results for ventral prostate sectors whereas RTE was superior in dorsal and apical sectors. MRI/RTE fusion improved sensitivity and specificity to 65.9% and 75.3%, respectively. Additional use of DCE sequences showed a sensitivity and specificity of 65% and 55.7% for MRI and 72.1% and 66% for MRI/RTE fusion. CONCLUSION MRI/RTE fusion provides improved PCa visualization by combining the strength of both imaging techniques in regard to prostate zonal anatomy and thereby might improve future biopsy-guided PCa detection.

Abstract
BACKGROUND Adipose tissue is increasingly considered as an endocrinal active organ and may have an influence on the development and progression of prostate cancer. Adverse body fat distribution, considered a risk factor for cardiovascular disease, is not reflected by the body mass index (BMI). OBJECTIVE The purpose of this work was to assess anthropometric indices which provide a better estimate of body fat distribution and to evaluate their association with clinical and histopathological parameters of prostate cancer. PATIENTS AND METHODS In patients scheduled for radical prostatectomy between March 2011 and March 2013, height, weight, waist circumference (WC) and hip circumference were measured, then the BMI, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were calculated. The relationships between anthropometric measures and indices and clinical and histopathological features of PCA were evaluated with uni- and multivariate analyses. RESULTS In 668 patients available for evaluation, obesity rates were 22.8 %, 50.6% and 30.2 % as defined by BMI ≥ 30, WHR ≥ 1 and WHtR ≥ 0.6, respectively. On univariate analysis, WC and WHtR ≥ 0.6 correlated with tumor volume (TV) > 2.1 cm(2) (p < 0.05), respectively. WC and WHtR were independent predictors of a TV ≥ 2.1 cm(2) (p < 0.05) and a WHtR ≥ 0.6 was an independent predictor of a TV ≥ 2.1 cm(2) (p < 0.018, risk ratio 1.506, 95 % confidence interval 1.072-2.115). CONCLUSION In general a higher degree of adiposity seems to correlate with a higher tumor volume. Whether anthropometric indices have prognostic impact needs to be clarified during follow-up.

Abstract
The aim of this study was to evaluate whether real-time elastography-guided biopsy in comparison to grey-scale ultrasound improves prostate cancer detection in patients with an unremarkable digital rectal exam.A total of 231 patients suspicious for prostate cancer were prospectively randomised to transrectal real-time elastography- (126) or grey-scale ultrasound (105)-guided biopsy. The peripheral zone was divided into 6 sectors from base, mid-gland to apex. Lesions with reduced elasticity during real-time elastography and hypoechoic areas during grey-scale ultrasound were defined as suspicious for prostate cancer. Prostate biopsy was guided by real-time elastography (RTE) or grey-scale ultrasound (GSU) using a systematic 10-core approach. Suspicious lesions on RTE or GSU in the corresponding randomised group were targeted within each sector. Accuracy of cancer prediction and histopathological cancer detection rates were evaluated and compared between the 2 imaging modalitiesBaseline characteristics of patients undergoing real-time elastography and grey-scale ultrasound, including age, prostate-specific antigen and prostate volume were not significantly different statistically (p>0.05). Overall, prostate cancer was detected in 76 of 231 cases (32.9%). The cancer detection rate was significantly higher (p=0.007) in patients who underwent a biopsy using real-time elastography (40.5%) compared to the grey-scale-guided group of men (23.8%). Sensitivity and specificity to detect prostate cancer in 1 386 prostate sectors was 53.5% and 70.5% for real-time elastography vs. 11.7% and 93.7% for grey-scale ultrasound, respectively.Compared to conventional grey-scale ultrasound, accuracy to detect prostate cancer using a systematic 10-core biopsy approach was significantly improved under the guidance of real-time elastography.

Abstract
Radical cystectomy (RC) represents the gold standard in the treatment of muscle invasive urothelial cancer of the bladder. Due to improvements in operation techniques and perioperative care it has become a good and safe procedure even in elderly patients. In recent years the Clavien-Dindo classification has been frequently used for complication assessment in urological research. The Charlson comorbidity index without age correction can be used in treatment planning for RC to identify patients at risk.

Abstract
BACKGROUND In 2002 the ten Martin criteria were proposed which should be met when reporting complications following surgery. Only a few studies have evaluated complication rates after open retropubic radical prostatectomy using these criteria. In this study we report on complications of open retropubic radical prostatectomy using the standardized Clavien-Dindo reporting methodology. PATIENTS AND METHODS The overall complication rate was 28.6% (907 of 3,172). We registered 1,069 medical or surgical complications in 907 patients. Of these, 714 complications were grade I (66.8%), 195 grade II (18.2%), 139 grade III (13%), and 17 grade IV (1.6%), respectively. The mortality rate (grade V) was 0.1% (4 of 3,172). Older age (hazard ratio 1.049, p=0.023) and a performed lymphadenectomy (hazard ratio 1.804, p=0.024) were independent predictors for high-grade complications (grade III or greater) on multivariate analysis. RESULTS Between 08/2003 and 06/2010 complications of 3172 consecutive men who underwent open retropubic radical prostatectomy at a single center were recorded prospectively. Complications which occurred within a period of 30 days postoperatively were graded retrospectively according to the Clavien-Dindo classification. Clinical and histopathological risk factors were statistically evaluated for an association with complication grades. All 10 Martin criteria were fulfilled. CONCLUSIONS Using the Clavien-Dindo classification as a standardized reporting methodology, we observed an acceptable overall complication rate of 28.6%. In the majority (85% of all complications) lower grade complications occurred. In this series older age and a lymphadenectomy were risk factors for high-grade complications (III-V). A patient's age remains an important factor when considering the indication for radical prostatectomy.

Abstract
Antimuscarinic drugs are regarded as the standard treatment of detrusor overactivity (DO). However, side effects and lack of efficacy cause patients to discontinue long-term therapy. We evaluated the clinical efficacy of functional external electrostimulation (FES) as "second-line" therapy in patients with symptomatic idiopathic or neurogenic DO.In a retrospective study, 52 patients (38 women and 14 men) were evaluated at least 1 year after FES. Eighteen patients (32.7%) regarded FES as successful. No change occurred in 34 patients (65.4%) and 1 patient reported worsening of symptoms. Treatment success lasted for 13.2 months. In successfully treated patients, voiding frequency was significantly reduced from 13.3/24 h to 6.1/24 h under FES and to 6.75/24 h at follow-up. FES is a clinically useful, well-tolerated, conservative second-line treatment option after failed antimuscarinic treatment in patients with idiopathic or neurogenic DO.

Abstract
Recent retrospective monocentric studies have demonstrated favorable 15-year cancer-specific survival (CSS) rates of up to 86% using radical prostatectomy as part of multimodal treatment in locally advanced prostate cancer (T3-4, N0, M0). Patients most likely to benefit from surgery include those with a biopsy Gleason score < or =8, a prostate-specific antigen level <20 ng/ml, and cT3a cancer. Patients must be informed that additional treatment after prostatectomy might be necessary (30-70%; radiotherapy, hormonal therapy). Urinary incontinence may occur in up to 20%, and severe incontinence (more than two pads per day) is observed in up to 6%.Adjuvant radiotherapy should be considered individually and is not routinely recommended. Extended pelvic lymphadenectomy should be performed, although it has only a minor impact on survival. However, even in patients with lymph node micrometastasis, 10-year CSS can be achieved in 85.6% with the use of additional hormonal therapy. Cancer progression can possibly be delayed by surgical excision of the primary tumor, even in patients with metastasis. The existing data must be checked in prospective randomized trials.

Abstract
OBJECTIVE We determined if transrectal ultrasound (TRUS) is as reliable as cystography in detecting vesicourethral extravasates after radical retropubic prostatectomy (RRP). PATIENTS AND METHODS Between October 2005 and February 2006 we prospectively investigated 100 consecutive patients undergoing RRP. The vesicourethral anastomosis was proven 6 days after operation by a combined investigation with TRUS and cystography. RESULTS In the majority of patients (79%) the vesicourethral anastomosis was watertight on postoperative day 6 (POD) or showed minimal leakage (8%) so that the urinary catheter was removed. Different degrees of paravasates were detected in 21 patients. Because of small, moderate, or marked paravasations the indwelling catheter was removed on POD 9, 14, and 21 in 5, 3, and 5 patients, respectively. Every paravasate documented by cystography had been detected by TRUS before. Therefore, TRUS showed no false-negative result in detecting insufficient anastomosis. In two patients paraurethral fluid was detected by TRUS mimicking anastomotic paravasation, without confirmation by cystography. CONCLUSIONS TRUS can safely replace cystography to detect anastomotic leakage after radical prostatectomy.

Abstract
Ileum or colon interpositions are qualified procedures for functional ureteral replacement in case of extended ureteric lesions. In most cases, a unilateral interposition is sufficient. Rarely, it is necessary to perform bilateral procedures. We report the case of a 41-year-old female patient with bilateral ureter implantation into a singular ileum segment.

Abstract
UNLABELLED Vasovasostomy is the most commonly performed procedures in the therapy for occlusive azoospermia after vasectomy. In our clinic the two-layer microsurgical technique (DL VVST) is considered to be the gold standard. We have examined the results of DL VVST by means of a questionnaire and compared them with those of the monolayer technique (ML VVST). MATERIALS AND METHOD In the period from 1996 to 2001, a microsurgical DL VVST with 10 x 0 Prolene sutures under the operation microscope was performed in 141 patient. Aspects of the operation, social aspects and postoperative results (results of spermiogram, birth rates) were assessed by means of a questionnaire. The results were compared with those of a historical patient collective who had undergone a modified monolayer VVST with 7 x 0 Prolene (n = 64). RESULTS The questionnaire could be sent to 90/141 patients, the response rate was 63/90 (70 %). The time interval between vasectomy and VVST was on average 9.5 years. The patency rate was 86 %, the birth rate 24 %. Severe or moderately sever complications did not occur. In the historical patient collective, the average occlusion interval was 6.9 years. The patency rate in these patients in whom the VVST was performed merely under the loupe and in a monolayer technique was 87 %, the pregnancy rate 48 %. CONCLUSION The highly positive results of VVST with pregnancy rates > 80 % from earlier publications could not be reproduced. According to our results, the two-layer VVST does not afford better results than the monolayer technique.

Abstract
The tension-free pubourethral sling procedure using a small intestinal submucosa sling (e.g., Stratasis, Cook Urological, Spencer/IN, USA) is of interest to the reconstructive urologist because of its reported regenerative capabilities and lack of immunogenicity. We report a severe postoperative inflammatory complication 4 weeks after the procedure. Severe inflammation with abscess formation led to reconstructive surgery to deal with the secondary complications.

Abstract
Detection of prostate-specific antigen remains the mainstay in the early detection of prostate cancer. A problem yet unsolved is the lack of specificity of this organ- but not cancer-specific marker, which generates subsequent, invasive procedures in a high number of patients without detecting prostate cancer. While the separate detection of free PSA and the ratio of free to total PSA has significantly improved specificity while maintaining high sensitivity, the number of patients undergoing unnecessary further diagnostics is still of concern. In this context, the evolving knowledge on isoforms of free PSA is a major focus of current research. Isoforms of free PSA are variants of free PSA that circulate, e.g., as precursor forms, internally cleaved variants of intact molecules, and are suggested to be either more associated with cancer or more with benign diseases. This article describes biochemical and clinical properties of the isoforms of free PSA.

Abstract
Radical prostatectomy for the treatment of prostate cancer can be performed by various techniques using a retropubic, perineal, or laparoscopic approach. Besides tumor control, the postoperative urinary continence rates and potency rates impact patients' quality of life after radical prostatectomy. This paper shows the results of our own center and compares the data in the literature regarding functional results of radical prostatectomy with respect to various operative techniques.

Abstract
OBJECTIVES To present a single-centre study investigating aneuploidy at chromosomes 3, 7, 17 and 9p21 (e.g. loss at 9p21) using a multitarget fluorescence in situ hybridization (FISH) system, as identifying genetic alterations in urine specimens is a promising approach for the noninvasive detection of bladder cancer. PATIENTS AND METHODS Urine samples from 103 patients were evaluated, including those from 46 with histologically confirmed urothelial carcinoma, two with other urological malignancies, and 55 who acted as controls. The urine samples were taken before any manipulation. The validity of FISH (Urovision, Vysis, Downers Grove, Ill, USA) was compared with other noninvasive urine tests, including the BTA-Stat test, the nuclear matrix protein (NMP)-22 test, and immunocytology against 486p3/12 and LewisX. Those evaluating the tests were unaware of the clinical and histopathological data. FISH was considered positive if five or more urinary cells had gains of two or more chromosomes. The threshold for the urine tests were 10 U/mL (NMP-22), 30% positive cells (486p3/12), or 5% positive cells, respectively (LewisX). RESULTS The sensitivity was 69% (FISH), 67% (BTA-Stat), 69% (486p3/12), 96% (LewisX) and 71% (NMP22), respectively; the respective specificity was 89%, 78%, 76%, 33% and 66%. CONCLUSION Multitarget FISH had a better specificity than the other urine markers but because of its inadequate sensitivity it does not seem to be powerful enough to replace endoscopy. Optimizing the marker panel could provide a higher sensitivity.

Abstract
OBJECTIVE Discussed is the clinical use of radical prostatectomy in patients with clinically localized prostate cancer regarding outcome, quality of life, and morbidity based on own data and results of the literature. METHODS A review of the currently available literature was performed. Moreover, data of 1755 patients who underwent radical retropubic prostatectomy between 1992 and 2001 at our institution were analyzed in uni- and multivariate analyses and included. RESULTS 5-year disease-specific survival of about 80% is reported. Pathologic stage and the Gleason score are the most influencing factors on postoperative outcome. Continence rates of about 90% are common; nerve-sparing radical prostatectomy seemed to have a protecting factor on continence. Rates of erection depend on the extent of nerve sparing and achieve up to 90% after bilateral nerve sparing. 30-day perioperative morbidity decreased to less than 5% in mayor series with a mortality rate of nil. CONCLUSIONS Selecting the right patient with clinically localized disease, radical prostatectomy showed excellent data on long-term follow-up. Due to respectful understanding of anatomical structures and improvements in surgical techniques, morbidity of the operation decreased and with the nerve-sparing technique quality of life increased.

Abstract
The quality of life of patients after radical prostatectomy is mainly influenced by erectile dysfunction (ED) and incontinence. New criteria for treatment and patient selection give us the opportunity to restore sexual function in more patients. When ED is present, we should not wait for 24 months for natural restitution. PDE-5-inhibitors, intracavernosal self injection therapy and the vacuum constriction device are effective and conform to both patient and economic preference.Therefore, every urologists should be able to offer his patients an individual and successful approach to the therapy of ED after prostate cancer.

Abstract
In patients suffering from prostate cancer, preoperative nomograms, which predict the risk of recurrence may provide a helpful tool in regard to the counselling and planning of an appropriate therapy. The best known nomograms were published by the Baylor College of Medicine, Houston and the Harvard Medical School, Boston. We investigated these nomograms derived in the U.S. when applied to German patients. Data from 1003 patients who underwent radical prostatectomy at the University-Hospital Hamburg were used for validation. Nomogram predictions of the probability for 2-years (Harvard nomogram) and 5-years (Kattan nomogram) freedom from PSA recurrence were compared with actual follow-up recurrence data using areas under the receiver-operating-characteristic curves (AUC). The recurrence free survival after 2 and 5 years was 78% and 58%, respectively. The AUC of the Harvard nomogram predicting 2-years probability of freedom from PSA recurrence was 0.80 vs. Kattan-Nomogram 5-years prediction of 0.83. Thereby, the Kattan nomogram showed a significant higher predictive accuracy (p=0.0274). For that reason preoperative nomograms derived in the U.S. can be applied to german patients. However, we would recommend the utilization of the Kattan nomogram due to its higher predictive accuracy.

Abstract
Prostate carcinomas located in the transition zone are suspected to behave differently from the more frequent peripheral zone cancers. In this study, large transition zone prostate cancers were investigated for pathological and clinical features. From 365 consecutive radical prostatectomy specimens, 73 cases were disclosed with tumours larger than 10 cm(3). Of these, 14 were predominantly (>70% tumour area) located in the transition zone. Pathological investigations included a complete histological work-up, immunohistochemistry for p53 and bcl-2, and interphase cytogenetics for chromosomes 7, 8, 17, and X. Despite large tumour volumes and high preoperative prostate specific antigen (PSA)-values, most tumours showed quite favourable pathological features. Only two of these patients suffered from a postoperative PSA-recurrence during a median follow-up of 50 months. For comparison, 36 cases that contained tumours predominantly located in the peripheral zone mostly displayed adverse prognostic signs and 68.8% of these patients suffered from postoperative PSA-recurrence. We conclude that the peculiar pathological and clinical characteristics of large prostate cancers in the transition zone might be important for prognostic considerations.

Abstract
Laparoscopic radical prostatectomy (LRP) offers an alternative to open prostatectomy in the treatment of clinically localized prostate cancer. However, when considering this new approach, oncological and functional results must be comparable to those of open retropublic prostatectomy (RRP). Long-term follow-up data for LRP are still lacking. RRP shows biochemical-free survival rates of 80% after 5 and 10 years. When evaluating functional results, data for postoperative erectile function after LRP are unclear. The functional data of postoperative continence after LRP seemed to be comparable to those of RRP. Even when considering aspects of morbidity and economy, RRP remains the golden standard in the treatment of clinically localized prostate cancer. Oncological and functional results are still preliminary for LRP.

Abstract
Prostate-specific antigen (PSA or hK3) is a glandular kallikrein with abundant expression in the prostate that is widely used to detect and monitor prostate cancer (PCa), although the serum level is frequently elevated also in benign and inflammatory prostatic diseases. PSA testing is useful for early detection of localized PCa and for the detection of disease recurrence after treatment. However, PSA has failed to accurately estimate cancer volume and preoperative staging. There is no PSA level in serum that definitively distinguishes men with benign conditions from those with prostate cancer, although PCa is rare in men with PSA levels in serum < 2.0 ng/ml. This prompted searches for enhancing parameters to combine with PSA testing, such as PSA density, PSA velocity, and age-specific reference ranges. Due to the protease structure, PSA occurs in different molecular forms in serum and their concentrations vary according to the type of prostatic disease. Human glandular kallikrein 2 (hK2) is very similar to PSA, but expressed at higher levels in prostate adenocarcinoma than in normal prostate epithelium. Blood testing for hK2 combined with different PSA forms improves discrimination of men with benign prostatic disease from those with prostate cancer. Many data have also been reported on the extra-prostatic expression of both PSA and hK2, and it is now believed that they may both have functions in tissues outside the prostate.

Abstract
BACKGROUND We measured serum levels of human glandular kallikrein 2 (hK2) in patients treated with radical retropubic prostatectomy (rrP) for clinically localized prostate cancer (PCa) with a total PSA (tPSA)-level below 10 ng/ml to investigate whether hK2 can be applied to preoperatively distinguish organ-confined (pT2a/b) from nonorgan-confined (> or = pT3a)-PCa more accurately than total PSA. Further, we evaluated hK2, free- and tPSA-concentrations in all pathologic stages of PCa. METHODS 161 serum samples from men scheduled for rrP were collected 1 day before surgery prior to any prostatic manipulation. Pathologic work-up revealed > or = pT3a-PCa in 48 and pT2a/b-PCa in 113 patients. HK2-levels in serum were measured using an immunofluorometric assay with an analytical sensitivity of 0.5 pg/ml, a functional sensitivity of 5 pg/ml and insignificant cross-reactivity with PSA (< 0.005%). Total (tPSA) and free PSA (fPSA) levels were measured using a commercially available assay from which we calculated %fPSA and an algorithm that combined hK2 and PSA-levels [hK2] x [tPSA/fPSA]. Means, medians, and ranges were calculated for pT2a/b vs. >/= pT3a-PCa and for all pathologic stages. Statistical significance of differences was calculated using Mann-Whitney-U and Kruskal-Wallis tests. Calculation of receiver-operator-characteristic (ROC) curves were performed for hK2, [hK2] x [tPSA/fPSA] and tPSA to compare diagnostic performance. RESULTS A mean tPSA level in serum of 6.12 ng/ml in > or = pT3a-PCa was not significantly different (P = 0.366) from 5.78 ng/ml in pT2a/b-PCa. Also, there were no statistically significantly different levels of fPSA (P = 0.947) or %fPSA (0.292) for these two groups. By contrast, mean hK2-level in pT2a/b-PCa of 80 pg/ml was significantly different (P = 0.004) from a mean hK2 level of 120 pg/ml in > or = pT3a-PCa as shown by Mann-Whitney-analysis Moreover, the algorithm of [hK2] x [tPSA/fPSA] was significantly lower (P = 0.0004) in pT2a/b-PCa vs. > or = pT3a-PCa. Calculation of areas under curve (AUC) by receiver-operator-characteristics (ROC) demonstrated that the AUC for hK2 (0.64) was larger and the AUC for [hK2] x [tPSA/fPSA] (=0.68) significantly larger (P = 0.007) compared to the AUC of tPSA (0.55). Furthermore, Kruskal-Wallis Test revealed a highly significant correlation to pathologic stage using hK2 (P = 0.008) and [hK2] x [tPSA/fPSA] (P = 0.0015) compared to no significant differences in serum concentration of tPSA (P = 0.296). Also at tPSA-levels from 10-20 ng/ml, the hK2-levels in pT2a/b-PCa were close to significantly different (P = 0.051) from those in men with >/= pT3a-PCa, while the algorithm of [hK2] x [tPSA/fPSA] in that tPSA-range was significantly lower (P = 0.002) in pT2a/b-PCa compared to > or = pT3a0-PCa. CONCLUSIONS Highly significant differences in serum concentration enable hK2 to be a powerful predictor of organ-confined disease and pathologic stage of clinically localized prostate cancer, especially in the PSA-range below 10 ng/ml. As such, there are important clinical consequences for the application of hK2 for the adequate treatment of prostate cancer patients, i.e., the option of nerve-sparing surgery.

Abstract
Improved selection criteria have led to an increasing number of nerve-sparing radical retropubic prostatectomies (RRP) in patients with clinically localized prostate cancer. The results based on patient questionnaires regarding postoperative erectile function are described. Between January 1992 and March 1999, 366 patients (mean age: 62.5 years) underwent uni- or bilateral nerve-sparing RRP at our institution. For evaluation of postoperative patient-reported rates of sexual and erectile function, a questionnaire was used after a follow-up of at least 12 months. Data of five operation periods were analyzed. The results of the unilateral procedure for the five operation periods revealed consistent rates of 13-29% for erections sufficient for intercourse. Bilateral nerve-sparing procedures were almost exclusively performed in periods 3 to 5; only four patients from period 2 underwent the bilateral procedure. The rates of intercourse-sufficient erections were 25% (period 2), 61% (period 3), 50% (period 4), and 52% (period 5), respectively. The results of the unilateral procedure were disappointing. However, the bilateral nerve-sparing method achieved much better results inasmuch as about 50% of the patients reported recovery of erections sufficient for sexual intercourse.

Abstract
PURPOSE Nerve sparing radical prostatectomy for prostate cancer should be restricted to patients who harbor tumors without capsular penetration. To our knowledge the selection criteria for nerve sparing radical prostatectomy are not clearly defined. We investigated a panel of preoperative tumor characteristics with respect to their ability to predict organ confined tumor growth for each lobe of the prostate to indicate unilateral or bilateral nerve sparing radical prostatectomy. MATERIALS AND METHODS Nine preoperative tumor characteristics in 278 patients with clinically localized prostate cancer were included in retrospective univariate and multivariate tree structured regression analysis. The association of clinical stage, serum prostate specific antigen (PSA), PSA density, and results of transrectal ultrasound and systematic sextant biopsy, including a quantitative assessment of cancer in the biopsies with organ confined tumor growth, was statistically evaluated. Except for serum PSA and PSA density preoperative characteristics were considered separately for each prostate lobe. Multivariate analysis results were validated prospectively in 353 patients. RESULTS On univariate analysis the number of positive biopsies was the most useful single parameter with a positive predictive value of 83% in 274 lobes and a negative predictive value of 55%, followed by mm. of tumor in the biopsy. Of all characteristics included in multivariate analysis only the number of biopsies with high grade cancer, the number of positive biopsies and serum PSA were independent for predicting organ confined cancer. When PSA was less than 10 ng./ml. and not more than 1 biopsy with high grade cancer was identified in a lobe, organ confined tumor growth was present in 86.1% of cases. On prospective validation the same criteria led to an 88.5% incidence of organ confined prostate cancer. Pooling the 2 most favorable groups led to 391 prostate lobes (70.8% of those investigated) with a positive predictive value of 82.1% (95% confidence interval 77.9% to 85.8%). Using the multivariate approach more prostate lobes were assigned to a favorable risk group than on univariate analysis. Clinical stage and simple Gleason grade did not contribute independent information for predicting organ confined disease. CONCLUSIONS Quantifying cancer and high grade cancer by systematic biopsy and serum PSA concentration are useful preoperative characteristics for predicting organ confined prostate cancer. Side specific analysis of these parameters is a flexible and reliable tool for selecting patients for nerve sparing radical prostatectomy.

Abstract
OBJECTIVES To investigate, in a retrospective analysis using a detailed questionnaire, the long-term functional results in and quality of life (QoL) of patients after undergoing the Essed-Schröder procedure, a standard technique for correcting penile curvature. PATIENTS AND METHODS From 1994 to 1999, 40 patients (median age 24 years) had their penile curvature corrected using a modified Essed-Schröder technique. Assessments by the investigators and a self-completed questionnaire were used to evaluate the functional and cosmetic aspects of the procedure, and QoL issues. RESULTS Complete follow-up data were available in 31 of the 40 (78%) patients (19 with congenital curvature and 12 with Peyronie's disease). The median follow-up was 22 months. The degree of penile angulation before surgery was estimated as < 45 degrees in five patients, 45-90 degrees in 22 and > 90 degrees in four. In 21 patients (68%) sexual intercourse was uncomfortable or impossible; 26 (84%) reported an impaired QoL because of the penile curvature. After surgery the cosmetic and functional result was good or sufficient in 25 patients (81%); all 25 were able to have sexual intercourse with no problems. Penile shortening (> 2 cm) was reported by six patients. A significant improvement in QoL was reported by 15 patients (48%), but of the 12 patients with Peyronie's disease before surgery, six reported impaired rigidity and two recurrence of their penile curvature afterward. Whereas only seven of 12 patients with Peyronie's disease reported good functional results, 18 of the 19 with congenital curvature reported good or excellent results after surgery. CONCLUSION The Essed-Schröder method is a simple operation which provides good functional and cosmetic results. Patients with congenital curvature of the penis have better results than those with Peyronie's disease.

Abstract
OBJECTIVE Depletion of serum LH by LHRH agonists is used as a therapeutic treatment in hormone-sensitive prostate cancer (PCa). However, little information on serum LH in different patient groups is available. METHODS Patients with biopsy-proven PCa, men with BPH (biopsy-proven absence of PCa), two subgroups (serum PSA <4 ng/ml; PCa and BPH), and a PCa cohort before and after radical prostatectomy were analyzed for serum LH, testosterone (T), dihydrotestosterone (DHT), total and free PSA by immunological procedures. RESULTS PCa patients with cancer volumes >10 cm(3), or with advanced Gleason scores, had significantly lower LH values than men in a cancer-free control group (PSA <4 ng/ml). Eight weeks after radical prostatectomy, LH levels had returned to the level of the control group (p<0.0001). These alterations were not accompanied by corresponding changes of serum androgens. Introduction of a PSA/LH ratio appeared to increase the differences between BPH and PCA groups ranked according to Gleason scores, versus PSA or LH alone. However, the calculation of ROC curves indicated that PSA/LH ratios may not improve the discrimination of malignant and benign forms of the disease, compared to presently used parameters. CONCLUSIONS A significant reduction of circulating LH is observed in the most advanced forms of PCa. The effect does not come about by T- or DHT-mediated feedback inhibition. Since LH values after prostatectomy returned to practically the same levels as seen in the control group (BPH with <4 ng/ml PSA), it appears that the healthy prostate has no marked influence on serum LH while advanced PCa induces a decrease in serum LH.

Abstract
The Schröder-Essed technique is a standard technique for correction of penile curvature. Although it has been described as a simple and rapid technique offering low morbidity, no data are available on long-term follow-up and life quality of the operated patients. In a retrospective analysis we investigated functional results and life quality (LQ) using a detailed questionnaire. From January 1994 to January 1999, 40 patients (median age 26) underwent correction of penile curvature using a slightly modified Schröder-Essed technique. We used a self-established questionnaire investigating functional and cosmetic aspects and LQ. Complete follow-up data are available in 31/40 (77.5%) patients (congenital curvature, 19 patients; Peyronie's disease, 12 patients). Median follow-up is 22 months. Degree of angulation before surgery was estimated at < 45 degrees in 5 patients, 45-90 degrees in 22 patients, and > 90 degrees in 4 patients. In 21/31 patients (67.7%) cohabitation was not possible or discomfortable. Impaired LQ due to penile curvature was reported by 26/31 patients (83.8%). After surgery, the cosmetic result was considered as good or sufficient in 25 patients. Cohabitation was possible in 25/31 patients (80.6%). Penile shortening (> 2 cm) was reported by six patients. Significant improvement of life quality was reported by 15 patients. Among the 12 patients with Peyronie's disease, 6 mentioned postoperative impaired rigidity. In two patients with Peyronie's disease penile curvature recurred. This simple operation technique offers good functional and cosmetic results. Particularly patients with congenital curvature reported good or excellent results. Patients with Peyronie's disease have to be informed about the risk of disease recurrence. Other operation techniques should be considered for these patients.

Abstract
OBJECTIVES To determine whether migration of pathological tumor stages in patients with clinically localized prostate cancer exists and whether this is due to an increasing frequency of treating patients with clinically insignificant cancer. METHODS 1,063 radical retropubic prostatectomies were performed in patients with clinically localized prostate cancer in one institution within 7.5 years (from 1992 until June 1999). All specimens were prospectively processed according to the Stanford protocol. These were then analyzed regarding the migration of pathological tumor stages and cancer volumes. RESULTS Within the observation period, the annual rate of radical retropubic prostatectomies increased by 225% from 69 to 224 cases. The authors noted a decline of advanced tumor stages (from 65 to 40%) and an increase in pathological T2 tumors (from 30 to 55%). The rate of small cancers (<0.5 cm(3)) remained stable between 2 and 5% over the last 5 years. CONCLUSION The data confirm trends which were observed in large US centers with increasing detection and treatment of localized prostate cancer without unnecessary treatment of clinically insignificant cancers.

Abstract
PURPOSE We measured serum levels of human glandular kallikrein 2 (hK2) in patients with prostate cancer treated with radical retropubic prostatectomy for clinically localized prostate cancer to determine whether preoperative hK2 levels discriminate stage pT2a/b from pathological stage T3a or greater cancer. This finding would help to predict preoperatively the organ confined versus non-organ confined growth of prostate cancer. MATERIALS AND METHODS A total of 68 consecutive men underwent radical retropubic prostatectomy for clinically localized prostate cancer. Serum was obtained 1 day preoperatively before prostatic manipulation. hK2, and total and free prostate specific antigen (PSA) were measured using immunofluorometric assays. Mean, median and range of hK2, total and free PSA, and the ratio of free-to-total PSA (percent free PSA) were calculated. Each analyte or combination of analytes was evaluated to determine whether it significantly contributed to enhance the discrimination of organ confined from non-organ confined cancer. We calculated the statistical significance of observed differences using the Mann-Whitney U and Kruskal-Wallis tests. Sensitivity and specificity calculations were performed for hK2, total PSA and the algorithm, (hK2) x (total PSA/free PSA) in addition to receiver operating characteristics curves and the respective areas under the curves. Multivariate logistic regression analysis was done for hK2, and total and free PSA RESULTS: Disease was organ and non-organ (extraprostatic extension) confined in 38 and 30 men, respectively. In organ confined cancer mean hK2 was significantly lower than in non-organ confined cancer (0.09 ng./ml., range less than 0.03 to 0.23 versus 0.30, range 0.04 to 0.94, p <0.0001). In addition, there was significantly higher free and total but not percent free PSA in non-organ than in organ confined cases. There were also statistically significant differences in hK2, free PSA and total PSA at each pathological disease stage (p <0.001, <0.01 and <0.05, respectively). Sensitivity for detecting organ confined disease was 37% at 100% specificity (correct identification of all non-organ confined cancer) using hK2 measurements compared with a sensitivity of 14% for total PSA. At a specificity of 95%, sensitivity was 40% for hK2 versus 23% for total PSA, which was a statistically significant gain in sensitivity (p <0.05). Receiver operating characteristics curves demonstrated that hK2 had the largest area under the curve, followed by the algorithm, (hK2) x (total PSA/free PSA), and total PSA (0.76, 0.75 and 0.72, respectively). However, none of area under the curve differences was statistically significant. CONCLUSIONS Compared with total and free PSA hK2 testing improved the preoperative evaluation of patients who underwent radical retropubic prostatectomy due to the superior discrimination of organ from non-organ confined cancer.

Abstract
Up to now there are no published results of therapy of paraphilia (Pedophilia, Sadism) and sexual aggressive impulsiveness with LHRH-(luteinizing hormone-releasing hormone) Agonists in the Germanspeaking countries. In this report we describe 11 patients which were treated with the LHRH-Agonist Leuprolide Acetate in a period of 12 months. The patients showed no tendency of sexual aggressive behaviour and reported an evident reduction of penile erection, ejaculation, masturbation, sexual deviant impulsiveness and fantasies. One patient died from suicide. In combination with other treatments LHRH-Agonists seem to be a very promising alternative to cyproterone acetate and its possible carcinogene effects.

Abstract
We report a case of mixed squamous-cell carcinoma with adenocarcinoma of the female urethra. A 37 year old women who presented with a 3-month' history of obstructive voiding symptoms. Clinical investigation showed a urethra tumor of 2.5 x 3.5 cm. Needle biopsy revealed a grade 3 carcinoma. Staging resulted in local cancer disease, a 2.5 x 3.5 cm tumor surrounding the whole urethra with protruding the trigonum. We performed urethrectomy with resection of the bladderneck and cystoneostomy. During bladderneck resection we performed regional staging lymphadenectomy of the obturator lymph nodes. Histological investigation revealed a mixed squamous-cell carcinoma with adenocarcinoma and undifferentiated carcinoma of the urethra. Periurethral tissue showed lymphangiosis carcinomatosa with negative lymph nodes. To exclude involvement of regional superficial lymph nodes we subsequently performed modified inguinal lymphadenectomy without evidence of advanced cancer disease.
