RESUMO
During a nephrectomy of a nonfunctioning, tumour-bearing kidney we found ectopic thyroid tissue in the kidney. This location of ectopic thyroid tissue has not been described before. In general, ectopic thyroid tissue is uncommon and rather found in the cervical region or upper mediastinum. A 131-iodine whole-body scan is the most precise method to detect the presence of ectopic thyroid tissue. It is often difficult to distinguish between benign and differentiated malignant thyroid tissue.

BACKGROUND: Since there is still an unmet need for potent adjuvant strategies for renal cancer patients with high progression risk after surgery, several targeted therapies are currently evaluated in this setting. We analyzed whether inclusion criteria of contemporary trials (ARISER, ASSURE, SORCE, EVEREST, PROTECT, S-TRAC, ATLAS) correctly identify high-risk patients. METHODS: The study group comprised 8873 patients of the international CORONA-database after surgery for non-metastatic renal cancer without any adjuvant treatment. Patients were divided into potentially eligible high-risk and assumable low-risk patients who didn't meet inclusion criteria of contemporary adjuvant clinical trials. The ability of various inclusion criteria for disease-free survival (DFS) prediction was evaluated by Harrell's c-index. RESULTS: During a median follow-up of 53 months 15.2% of patients experienced recurrence (5-year-DFS 84%). By application of trial inclusion criteria, 24% (S-TRAC) to 47% (SORCE) of patients would have been eligible for enrollment. Actual recurrence rates of eligible patients ranged between 29% (SORCE) and 37% (S-TRAC) opposed to <10% in excluded patients. Highest Hazard Ratio for selection criteria was proven for the SORCE-trial (HR 6.42; p < 0.001), while ASSURE and EVEREST reached the highest c-index for DFS prediction (both 0.73). In a separate multivariate Cox-model, two risk-groups were identified with a maximum difference in 5-year-DFS (94% vs. 61%). CONCLUSION: Results of contemporary adjuvant clinical trials will not be comparable as inclusion criteria differ significantly. Risk assessment according to our model might improve patient selection in clinical trials by defining a high-risk group (28% of all patients) with a 5-year-recurrence rate of almost 40%.

Transrectal ultrasound-guided prostate biopsy is considered the gold standard in the primary investigation of a suspicious prostate-related finding. The procedure can be carried out with ten probes or more on the lateral side of the prostate, after administering antibiotic prophylaxis and applying local anesthesia. The indication for a biopsy depends on the results of the digitorectal examination, on the serum prostate-specific antigen level, on the individual patient's wish and on his comorbidities. Whether multiparametric imaging should be used before or during the course of a primary or repeated biopsy in order to identify suspicious prostate lesions is the subject of current investigations. Extended biopsy protocols require further clinical investigations before they can become the new standard in the diagnostic work-up. This review delivers an update on the indication for, and technique of, prostate biopsies.

The aim of this prospective multi-centre study was to evaluate the level of psychological distress (PD) and adjustment to disease in patients who underwent radical prostatectomy. Furthermore, the impact of urinary incontinence and erectile dysfunction on PD was assessed. Anxiety, depression and PD were evaluated using the Hospital Anxiety and Depression Scale in 329 prostate cancer patients before surgery as well as 3, 6 and 12 months after surgery. These results were compared with those of a male German general population reference group. Adjustment to disease was assessed using the Perceived Adjustment to Chronic Illness Scale. Patients reported low levels of PD at all points of assessment similar to population norms of age-matched German men. Persistent PD was seen in about 8% of the patients and 20% had PD at least two of the measurement points. Relevant predictors for PD after surgery were urinary symptoms and baseline PD. Adjustment to disease was highest before surgery and had significantly reduced at 3 and 6 months after surgery. In general, men are resilient to the experience of localised prostate cancer and adjust well psychologically after surgery. However, between 8% and 20% of patients could possibly benefit from mental health support.

BACKGROUND: The chromophobe subtype represents the third most common histological subtype of renal cell carcinoma (chRCC). Due to the rarity of this subtype only one publication regarding the specific analysis of clinical and histopathological criteria as well as survival analysis of more than 200 patients with chRCC is known to date. MATERIALS AND METHODS: A total of 6,234 RCC patients from 11 centres who were treated by (partial) nephrectomy are contained in the database of this multinational study. Of the patients 259 were diagnosed with chRCC (4.2 %) and thus formed the study group for this retrospective investigation. These subjects were compared to 4,994 patients with a clear cell subtype (80.1 %) with respect to clinical and histopathological criteria. The independent influence of the chromophobe subtype regarding tumor-specific survival and overall survival was determined using analysis by Cox proportional hazards regression models. The median follow-up was 59 months (interquartile range 29-106 months). RESULTS: The chRCC patients were significantly younger (60 vs. 63.2 years, p < 0.001), more often female (50 vs. 41 %, p = 0.005) and showed simultaneous distant metastases to a lesser extent (3.5 vs. 7.1 %, p = 0.023) compared to patients with a clear cell subtype. Despite a comparable median tumor size a ≥ pT3 tumor stage was diagnosed in only 24.7 % of the patients compared to of 30.5 % in patients with a clear cell subtype (p = 0.047). In addition to the clinical criteria of age, sex and distant metastases, the histological variables pTN stage, grade and tumor size showed a significant influence on tumor-specific and overall survival. However, in the multivariable Cox regression analysis no independent effect on tumor-specific mortality (HR 0.88, p = 0.515) and overall mortality (HR 1.00, p = 0.998) due to the histological subtype was found (c-index 0.86 and 0.77, respectively). CONCLUSIONS: Patients with chRCC and clear cell RCC differ significantly concerning the distribution of clinical and histopathological criteria. Patients with chRCC present with less advanced tumors which leads to better tumor-specific survival rates in general; however, this advantage could not be verified after adjustment for the established risk factors.

CONTEXT: 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.

The frequent application of ultrasound and radiological imaging for non-urological indications in recent years has resulted in an increase in the diagnosis of small renal masses. The treatment options for patients with a small renal mass include active surveillance, surgery (both open and minimally invasive) as well as ablative techniques. As there is a risk for metastatic spread even in small renal masses surgical extirpation remains the treatment of choice in most patients. Ablative procedures, such as cryoablation and radiofrequency ablation are appropriate for old and multi-morbid patients who require active treatment of a small renal mass. Active surveillance is an alternative for high-risk patients. Meticulous patient selection by the urologist and patient preference will determine the choice of treatment option in the future.

Organ-confined prostate cancer can be treated with curative intent by different types of radiotherapy or by radical surgery. Regardless of improvements in radiotherapy about 60% of patients with prostate cancer develop biochemical recurrence (BCR) which is defined by the progressive increase in serum prostate-specific antigen (PSA) and necessitates further diagnostic procedures. If non-organ-confined cancer and metastasis are categorically excluded by cross-sectional imaging using computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography CT (PET-CT) and bone scintigraphy, a prostate biopsy should be performed. Biopsy proven detection of recurrent or persisting prostate cancer after irradiation is essential prior to a salvage prostatectomy. The function of the lower urinary tract should be evaluated prior to surgery. Preoperative PSA measurement is the best prognostic indicator prior to surgery. Salvage prostatectomy in irradiated patients is more challenging and requires extensive skill. The most common complications are incontinence, rectal injury and anastomotic strictures. Both functional and oncologic outcome have improved due to better irradiation techniques and surgical skills. Provided post-radiotherapy recurrence of prostate cancer is diagnosed early enough, curing is possible by salvage prostatectomy.

In contrast to ureterosigmoidostomy no reliable clinical data exist for tumor risk in different forms of urinary diversion using isolated intestinal segments.In 44 German urological departments, operation frequencies, indications, patient age, and operation dates of the different forms of urinary diversion, operated between 1970 and 2007, could be registered. The secondary tumors up to 2009 were registered as well and related to the numbers of the different forms of urinary diversions resulting in tumor prevalences.In 17,758 urinary diversions 32 secondary tumors occurred. The tumor risk in ureterosigmoidostomy (22-fold) and cystoplasty (13-fold) is significantly higher than in other continent forms of urinary diversion such as neobladders or pouches (p<0.0001). The difference between ureterosigmoidostomy and cystoplasty is not significant, nor is the difference between ileocecal pouches (0.14%) and ileal neobladders (0.05%) (p=0.46). The tumor risk in ileocecal (1.26%) and colonic neobladders (1.43%) is significantly higher (p=0.0001) than in ileal neobladders (0.5%). Of the 16 tumors that occurred following ureterosigmoidostomy, 16 (94%) developed directly at the ureterocolonic borderline in contrast to only 50% following urinary diversions via isolated intestinal segments.From postoperative year 5 regular endoscopic controls of ureterosigmoidostomies, cystoplasties, and orthotopic (ileo-)colonic neobladders are necessary. In ileocecal pouches, regular endoscopy is necessary at least in the presence of symptoms or should be performed routinely at greater intervals. Following neobladders or conduits, only urethroscopies for urethral recurrence are necessary.

BACKGROUND: Recently, it was reported that the soluble vascular endothelial growth factor receptor-2 (sVEGFR-2) is secreted by microvascular endothelial cells from human BPH (HPECs). The purpose of this study was to investigate the modulation of sVEGFR-2 by common endothelial cell stimulators. In addition, the physiological role of sVEGFR-2 with regard to the VEGF-stimulated proliferation of HPEC was investigated. METHODS: HPECs were isolated and cultured from fresh BPH tissue. After the incubation of HPECs either with adenosine triphosphate (ATP), interleukin (IL)-6, IL-8 or IL-12, the secretion of sVEGFR-2 was measured by enzyme-linked immunosorbent assay. For measurement of HPEC proliferation influenced by sVEGFR-2, VEGF-stimulated HPEC was cultured with/without sVEGFR-2. Cell proliferation was assessed with the Alamar Blue method. RESULTS: The sVEGFR-2 secretion was increased by ATP and decreased by IL-12 and IL-8, respectively. IL-6 did not show any significant effect on sVEGFR-2 secretion of HPECs. HPEC proliferation was significantly inhibited by sVEGFR-2. CONCLUSIONS: In this study, our data suggest that the secretion of sVEGFR-2 by microvascular endothelial cells from prostate origin is influenced by multiple endothelial cell stimulators. Furthermore, our data suggest that sVEGFR-2 acts as an antiangiogenic factor.

PURPOSE: The 7th edition of TNM for renal cell carcinoma introduced a subdivision of pT2 tumors at a 10 cm cutoff. In the present multicenter study the influence of tumor size as well as further clinical and histopathological parameters on cancer specific survival in patients with pT2 tumors was evaluated. MATERIALS AND METHODS: A total of 670 consecutive patients with pT2 tumors (10.4%) of 6,442 surgically treated patients with all tumor stages were pooled (mean followup 71.4 months). Tumors were reclassified according to the current TNM classification, and subdivided in stages pT2a and pT2b. Cancer specific survival was analyzed using the Kaplan-Meier method, and univariable and multivariable analyses were used to assess the influence of several parameters on survival. RESULTS: Tumor size continuously applied and subdivided at 10 cm or alternative cutoffs did not significantly influence cancer specific survival. In addition to N/M stage, Fuhrman grade and collecting system invasion also had an independent influence on survival. Integration of a dichotomous variable subsuming Fuhrman grade and collecting system invasion (grade 3/4 and/or collecting system invasion present vs grade 1/2 and collecting system invasion absent) into multivariate models including established prognostic parameters resulted in improvement of predictive abilities by 11% (HR 2.3, p <0.001) for all pT2 cases and 151% (HR 3.1, p <0.001) for stage pT2N0M0 cases. CONCLUSIONS: Tumor size did not have a significant influence on cancer specific survival in pT2 tumors, neither continuously applied nor based on various cutoff values. To enhance prognostic discrimination, multifactorial staging systems including pathological features should be implemented. The prognostic relevance of the variable subsuming Fuhrman grade and collecting system invasion should be considered for future evaluation.

Relatively long learning curves and, therefore, initially longer operating times compared to conventional procedures are still a matter of debate. Today, there are numerous possibilities for learning laparoscopic techniques and establishing one's own laparoscopic programs, including various pelvitrainers and virtual reality computer programs. One useful and realistic way involves "wet lab" training programs for ablative and reconstructive procedures using the pig model. Today, laparoscopic urological surgery includes procedures with low (e.g. laparoscopy for undescended testicles), intermediate (laparoscopic pyeloplasty) and high level (laparoscopic/endoscopic prostatectomy) complexity. Therefore, laparoscopy should be an integral part of training in urology. A defined number of possibly multi-institutional training centers with well structured educational programs are needed. The main goal should be the standardization of surgical procedures as well as educational training programs in order to shorten individual learning curves and generate common quality standards.

Results from experimental studies suggested a significance of the nitric oxide (NO)-cGMP- and cAMP-pathways in the control of the function of the smooth musculature of the human prostate. In addition, it has also been assumed that the vasoconstrictory peptide endothelin-1(ET-1) may play a role in the dynamic component of benign prostatic hyperplasia (BPH) and the so-called lower urinary tract symptomatology (LUTS). Nevertheless, up till now, little is known as to potential interactions between the contraction of prostatic smooth muscle mediated by ET-1 and the relaxation induced by NO and cGMP. Thus, it was the aim of the study to elucidate the effects of drugs interfering with the cGMP-pathway on the tension induced by ET-1 of isolated human prostate tissue, as well as contractile responses of isolated strip preparations to ET-1 and angiotensin-II (AT-II). Macroscopically normal human prostate tissue from the transition zone was obtained from male patients who had undergone surgery for localized cancer of the prostate or urinary bladder. Using the organ bath technique, the ability of ET-1 and AT-II to contract isolated prostate strips was evaluated. In another set-up, the effects of the NO-donor S-nitrosogluthatione (GSNO) and C-type natriuretic peptide(CNP), known as an endogenous ligand of the membrane bound guanylyl cyclase, (1 nM-1/10 microM) on the tension induced by 0.1 microM ET-1 of human prostate strips were investigated. The adenylyl cyclase stimulating agents forskolin and NO-donor natrium nitroprusside (NNP) were used as reference compounds. While AT-II failed to contract the prostate tissue, ET-1 induced stable and reproducible contractions of the tissue strips. The tension induced by 0.1 microM ET-1 was dose-dependently reversed by the drugs. The rank order of efficacy was forskolin >NNP>CNP(1 microM)>GSNO. R(max) values ranged from 55% (forskolin) to 35% (GSNO). Forskolin was the only compound which reached an EC50 value. Our results demonstrate that drugs in terfering with the cGMP- and cAMP-pathways can reverse the tension induced by ET-1. These findings are in support of the hypothesis that both cGMP and cAMP contribute to the control of the prostate smooth muscle tension and may provide new strategies for the future pharmacotherapy of LUTS und BPH.

PURPOSE: We assessed the feasibility of laparoscopic transabdominal dismembered pyeloplasty in 46 infants and children with regard to patient age. MATERIALS AND METHODS: A total of 46 consecutive infants and children (31 male and 15 female) underwent laparoscopic transabdominal dismembered pyeloplasty using a 3 to 4-trocar technique. All patients had confirmed unilateral deterioration of renal function on isotope renography. The 46 patients were divided into 3 age groups--1 to 12 months (group 1, 14 patients), 1 to 7 years (group 2, 15 patients) and 7 to 18 years (group 3, 17 patients). Followup included clinical and ultrasound assessment, and isotope renography at 3 months. RESULTS: Laparoscopic pyeloplasty was feasible in 44 of 46 patients (96%). Mean operative time was 175 minutes (range 120 to 270). The operation was converted due to impracticality of stenting the PUJ in 1 patient, and due to bleeding in 1. Mean operative time in 44 successful laparoscopic procedures was not significantly different among the 3 age groups (171 minutes in group 1, 169 minutes in group 2 and 173 minutes in group 3). Two patients required operative intervention for PUJ leakage, and 1 underwent percutaneous nephrostomy with a further uneventful course. Mean followup was 29 months (range 3 to 86). A total of 44 patients (96%) were asymptomatic and had improved PUJ drainage on isotope renography. Two patients underwent redo pyeloplasty due to recurrent hydronephrosis at 1 month and 2 years. CONCLUSIONS: Laparoscopic transabdominal dismembered pyeloplasty is effective and safe in infants and children. The feasibility is also excellent in patients younger than 1 year. The transabdominal approach revealed good exposition without a disadvantage for the patient.

Female sexual dysfunction and even female sexual function are widely unknown. We therefore evaluated the sexual behaviour of younger and older women using a questionnaire. A total of 998 young women entered the study at Hannover Medical school. They were between 19 and 43 years old (median 24 years), and 64% answered the questionnaire. A total of 97.1% of the female students were heterosexual, 1.6% were lesbians and 1.3% were bisexual. Lack of sexual intercourse in the previous month was recorded by 21.1%, while 21.3% recorded intercourse 1-3 times a month, 46.8% 1-3 times a week and 5.5% daily. Adverse reactions to sexual situations were reported by 25% of the women, 20.5% had a negative perception for special partners or circumstances. Some 55% of the evaluated women were satisfied with their sexual life in the last month, 20% were fairly satisfied and 21% were un-satisfied. This study of a selected population of medical students shows a wide variety of sexual problems with a high prevalence of different disorders.

During the last decade laparoscopy has become the standard technique in the urologist's armamentarium due to constant technological advancements and refinements. Laparoscopic radical prostatectomy (LRPE), although technically demanding and associated with a considerable learning curve, has become the operative procedure of choice for patients with clinically localized prostate cancer in selected and specialized urologic centers around the globe. However, a major drawback of LRPE is the transperitoneal route of access to the extraperitoneal organ of the prostate. The principal disadvantages of LRPE are potential intraperitoneal complications. Endoscopic extraperitoneal radical prostatectomy (EERPE) is a further advancement of minimally invasive surgery as it overcomes the limitations of LRPE by the strictly extraperitoneal route of access. Based on our growing experience with this procedure we introduce several technical modifications, improvements, and refinements including a nerve-sparing, potency-preserving approach (nEERPE) in an effort to further improve this minimally invasive procedure. We report our short-term follow-up results after 300 procedures. The mean operative times were 115 min without and 150 min with lymph node dissection, in total 140 min (range: 60-260 min). There was no conversion and the transfusion rate was 1.3%. There were three early reinterventions (two bleeding and one hematoma) and five late reinterventions (four symptomatic lymphoceles and one colostomy due to a rectal fistula). Pathological stage was pT2a in 54 patients (18%), pT2b in 87 patients (29%), pT3a in 115 patients (38.3%), pT3b in 40 patients (13.3%), and pT4 in 4 patients (1.3%). Positive surgical margins were found in 9.2% (13/141) of patients with pT2 tumor and 30.3% (47/155) of patients with pT3 tumor. The mean catheterization time was 6.9 days. Six and twelve months postoperatively 86.3 and 89.6% of the patients were completely continent; 9.2% of patients needed 1-2 pads per day and 4.5 and 1.2% of patients needed more than 2 pads per day, respectively. Short-term oncological and functional results of EERPE are at least as favorable as in LRPE while operative times are shorter and complication rates are low. EERPE is a technical advancement because it combines the advantages of a totally extraperitoneal access with the advantages of a minimally invasive procedure.

During the last decade laparoscopy has become a standard technique available to the urologist, through constant technological advances and refinements. The progress of laparoscopic/endoscopic techniques allows the indications for this surgery to include complex oncological procedures like radical prostatectomy. Since the first description of laparoscopic radical prostatectomy (LRP) in the early 1990s the technique has undergone significant technical modifications. Transperitoneal LRP is now a standard procedure and can be used successfully and reproducibly, giving results comparable with those from the open retropubic procedure. Despite many advantages, transperitoneal laparoscopy is associated with potential intraperitoneal complications. Because of the limitations inherent in the transperitoneal route, a totally extraperitoneal endoscopic radical prostatectomy (EERPE) has been developed. The totally extraperitoneal endoscopic access provides a safe and minimally invasive approach to various urological procedures, including prostatectomy. This technical improvement completely obviates intra-abdominal complications. EERPE combines the advantages of minimally invasive laparoscopy and the open retropubic approach. We review the surgical techniques of LRP and EERPE, and highlight the indications, contraindications and outcomes.
