Journal description

Concise but fully substantiated international reports of clinically oriented research into the etiology, pathophysiology and current management of urogenital disorders form the nucleus of original as well as basic research papers. These are supplemented by up-to-date reviews by international experts on the state-of-the-art of key topics of clinical urological practice. Essential topics receiving regular coverage include the introduction of new techniques and instrumentation as well as the evaluation of new functional tests and diagnostic methods. Special attention is given to advances in surgical techniques and clinical oncology. An expert discussion panel provides an international forum for exchanging ideas on the current management of clinical and technical problems of urologic surgery. The regular publication of selected case reports represents the great variation in urological disease and illustrates treatment solutions in singular cases.

    ABSTRACT: Objective: To determine whether listening to music during transrectal ultrasound (TRUS)-guided 12-core needle prostate biopsy decreases anxiety, pain and dissatisfaction among patients and results in a more comfortable and better tolerated procedure. Patients and Methods: 76 male patients who underwent TRUS-guided prostate biopsy between March 2013 and June 2014 were randomized into the following groups: no music (group I, n = 38) or classical music (group II, n = 38) during the procedure. Before TRUS-guided prostate biopsy, lidocaine gel was instilled into the rectum. Patient anxiety levels were quantified using the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for self-assessment of satisfaction, discomfort and willingness among patients to have a repeat TRUS-guided prostate biopsy. Results: Demographic characteristics, mean age, procedure duration and procedure indications did not differ statistically between the two groups. The mean anxiety level and mean pain score of group II were significantly lower than those of group I (p = 0.001 and p = 0.003, respectively). Group II also had a significantly higher mean satisfaction score than group I (p = 0.007). Before the procedure, heart rate and systolic blood pressure were similar in groups I and II; however, after the procedure, levels were lower in group II than in group I (heart rate, p = 0.014; systolic blood pressure, p = 0.011). Conclusion: Listening to music during TRUS-guided prostate biopsy significantly reduced patients' feelings of pain, discomfort and dissatisfaction. Music can serve as a simple, inexpensive and effective adjunct to sedation during TRUS-guided prostate biopsy. We recommend playing music during TRUS-guided prostate biopsy. © 2014 S.

    ABSTRACT: Non-clear cell renal cell carcinoma accounts for about 20% of all kidney cancers. Tubulocystic carcinoma of the kidney (TCK) is a newly described entity with distinct molecular, genetic and clinical features. In 2013, it was one of five new renal tumors to be recognized by the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia. We describe here a case of TCK with a rare genetic signature, unusual metastases and limited response to an anti-vascular endothelial growth factor inhibitor in what we believe is the youngest patient on record to date. © 2014 S.

    ABSTRACT: Due to the lack of disease-specific symptoms, diagnosis and follow-up of bladder cancer has remained a challenge to the urologic community. Cystoscopy, commonly accepted as a gold standard for the detection of bladder cancer, is invasive and relatively expensive, while urine cytology is of limited value specifically in low-grade disease. Over the last decades, numerous molecular assays for the diagnosis of urothelial cancer have been developed and investigated with regard to their clinical use. However, although all of these assays have been shown to have superior sensitivity as compared to urine cytology, none of them has been included in clinical guidelines. The key reason for this situation is that none of the assays has been included into clinical decision-making so far. We reviewed the current status and performance of modern molecular urine tests following systematic analysis of the value and limitations of commercially available assays. Despite considerable advances in recent years, the authors feel that at this stage the added value of molecular markers for the diagnosis of urothelial tumors has not yet been identified. Current data suggest that some of these markers may have the potential to play a role in screening and surveillance of bladder cancer. Well-designed protocols and prospective, controlled trials will be needed to provide the basis to determine whether integration of molecular markers into clinical decision-making will be of value in the future. © 2015 S.

    ABSTRACT: Epithelioid hemangioendothelioma (EHE) is a rare tumor of the urinary system. Only three cases of EHE of the bladder have been reported to date, and the biological properties of the tumor in this location remain poorly characterized. We report a case of primary EHE of the urinary bladder in a 58-year-old woman who was treated by transurethral resection and review the existing literature on the diagnosis and treatment of EHE of the bladder. © 2015 S.

    ABSTRACT: Objective: To analyze current evidence comparing the safety and outcomes of regional and global ischemia for partial nephrectomy (PN). Materials and Methods: A systematic search of the PubMed and Web of Science databases was conducted in May 2014 to identify studies comparing the safety and outcomes of regional and global ischemia for PN. A systematic review and meta-analysis was also performed. Results: Six retrospective observational studies were selected for the analysis, including 363 patients who underwent PN (162 regional ischemia and 201 global ischemia cases). Operation times were not statistically different [weighted mean difference (WMD) = 20.35 min, 95% CI: -0.28-40.97, p = 0.05], but estimated blood loss was significantly higher in the regional ischemia group (WMD = 52.04 ml, 95% CI: 14.30-89.78, p = 0.007) than in the global ischemia group. Complication rates [odds ratio (OR) = 1.16; 95% CI: 0.63-2.15, p = 0.63] and blood transfusion rates (OR = 1.85; 95% CI: 0.86-4.01, p = 0.12) of the two groups were not significantly different. The regional ischemia group showed better postoperative renal function (WMD = 4.23 ml/min, 95% CI: 2.61-5.85, p < 0.00001) than the global ischemia group, and all cases in the regional ischemia group showed negative margins. Conclusions: Regional ischemia is as safe to perform as global ischemia, and the former leads to better postoperative renal functions than the latter. These findings support the application of regional ischemia for PN. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objectives: To evaluate prognostic factors in pT1b renal cell carcinoma (RCC) patients for which no specific studies have been conducted on. Methods: The data of 270 patients diagnosed with pT1bN0M0 RCC at 2 institutions between January 1998 and June 2010 were retrospectively analyzed. Univariate and multivariate analyses using Cox proportional hazard models were used to identify pathologic and clinical factors that influenced prognosis. Five-year recurrence-free survival and cancer-specific survival were analyzed using the Kaplan-Meier method. Results: The median follow-up period was 55.5 months, and the mean patient age was 55.2 years (range: 26-80). There were 12 cancer-related deaths, and tumor recurrence was noted in 22 patients between 8 and 120 months after surgery. Sites of metastases included the lung in 13 patients, bone in 5 patients, and other sites in 4 patients. Five-year recurrence-free survival and cancer-specific survival rates were 91.2 and 93.5%, respectively. Multivariate analyses revealed that the presence of microvascular invasion and tumor necrosis independently predicted prognosis. Conclusions: Microvascular invasion and tumor necrosis were found to be independent prognostic factors in pT1b RCC. This result will help urologists to provide patients with more accurate prognoses, and patients with confirmed microvascular invasion and tumor necrosis will require closer follow-up. © 2014 S.

    ABSTRACT: Objective: To explore the outcome of transurethral resection of the prostate (TURP) in the treatment of refractory recurrent acute bacterial prostatitis. Patients and Methods: From 2004 to 2013, 23 TURP for this indication were performed in 21 patients; two patients underwent it twice. The files of these patients were retrospectively analysed for outcome and side effects. TURP intended to remove as much infected tissue as possible under appropriate antibiotherapy. Results: Twelve patients became free of symptoms during a follow-up of 3-108 months (median 44), two others became disease-free after one and two postoperative attacks, respectively; eight were not cured and had rapid recurrences; three patients had follow-up of a few weeks only. Two failures developed orchiepididymitis shortly after the procedure and one a year later. No incontinence or bladder neck contracture was noted. Conclusion: TURP is an acceptable procedure in the treatment of refractory recurrent bacterial prostatitis. It could cure about two thirds of patients. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objective: This study presents our initial experience with extraperitoneal and transperitoneal laparoscopic partial cystectomy (LPC) in the treatment of benign non-urothelial bladder tumors. Methods: Eleven patients with benign non-urothelial bladder tumors underwent extraperitoneal or transperitoneal LPC. The five cases with tumors located on the anterior/anterolateral bladder wall received the extraperitoneal approach. The six cases with tumors located around the bladder dome or over the posterior bladder wall received the transperitoneal approach. Key perioperative parameters were recorded. Results: All patients underwent laparoscopic resection smoothly without requiring a conversion to a traditional open procedure, and no patient displayed perioperative complications. Pathology showed benign non-urothelial bladder tumors with normal margins in all eleven patients, including five leiomyoma cases, three pheochromocytoma cases, two paraganglioma cases and one inflammatory fibrous histiocytoma case. Follow-up cystoscopy and imaging studies in all eleven patients (mean follow-up period 32 months) revealed neither residual nor local recurrence. Conclusions: LPC is safe and feasible in select patients with benign non-urothelial bladder tumors and yields satisfactory oncological and functional results. Extraperitoneal LPC should be preferred for lesions located on the anterior/anterolateral bladder wall, while transperitoneal LPC should be preferred for lesions around the bladder dome or over the posterior bladder wall. © 2014 S.

    ABSTRACT: Objective: To investigate the efficacy of diethylstilboestrol (DES) in patients with advanced prostate cancer refractory to androgen suppression. Methods: This retrospective study comprises 194 patients with prostate cancer treated with DES (1 mg daily) between 1976 and 2010. Study outcome parameters included demographic data, tumour characteristics, treatment history, prostate-specific antigen (PSA) responses, radiologic studies, adverse events and overall survival. Results: At initiation of oestrogen therapy the mean patient age was 69 years (range: 48-89) and the median PSA was 96 ng/ml (range: 1.9-9,500). The median duration of prior prostate cancer treatment was 29 months (range: 1-365). DES was the second-line treatment in 58 patients and the third/fourth-line therapy in 136 men. A formal (≥50%) PSA response was observed in 95 patients (48.9%) and the median time to progression (TTP) was 250 days (95% CI, 180-360) for this group. An additional 62 patients (31.9%) had a partial PSA response with a median TTP of 150 days (95% CI, 92-180). Thirty-seven patients (19.1%) did not have a PSA response and the median TTP was 90 days (95% CI, 90-97). The median overall survival from the start of oestrogen therapy for the entire cohort was 576 days (95% CI, 482-690). The median overall survival of patients who had a formal (≥50%), partial (<50%) and no PSA response was 756 (95% CI, 670-1,429), 428 (95% CI, 340-630) and 329 (95% CI, 287-510) days, respectively. Thirty-nine patients (20.1%) were still alive at the end of the study. No treatment-related deaths occurred. Conclusions: In the age of chemotherapy this study highlights the efficacy of oestrogen therapy in castration-refractory prostate cancer. The optimal point in the therapeutic pathway at which DES should be prescribed remains to be established. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objective: To identify the prognostic factors causing persistent storage symptoms following transurethral resection of the prostate in patients with benign prostatic enlargement (BPE). Methods: A total of 116 men with symptomatic BPE requiring surgery were enrolled in the study between January 2011 and December 2012. The patients underwent basic clinical evaluations including transrectal ultrasound, International Prostate Symptom Score and urodynamic study. After 6 months, International Prostate Symptom Score and uroflowmetry were rechecked. The definition of persistent storage symptoms was patients with storage scores >7 points. Logistic regression analysis and receiver operating characteristic analysis were conducted. Results: The 116 patients were divided into a persistent storage symptom-positive group (n = 33) and a storage symptom-negative group (n = 83). Multivariate analysis showed that the degrees of worse initial storage symptoms (odds ratio [OR] = 8.32), small bladder capacity (OR = 4.31), impaired detrusor contractility (OR = 2.96) and age (OR = 1.05) were consistently associated with persistent storage symptoms. Conclusions: This short-term study confirms the positive and consistent correlations between the baseline degree of worse initial storage symptoms, bladder capacity, detrusor contractility and age and the improvement in storage symptoms. © 2014 S.

    ABSTRACT: Objectives: Despite the wide diffusion of minimally invasive approaches, such as laparoscopic (LRP) and robot-assisted radical prostatectomy (RALP), few studies compare the results of these techniques with the retropubic radical prostatectomy (RRP) approach. The aim of this study is to compare the surgical, functional, and oncological outcomes and cost-effectiveness of RRP, LRP, and RALP. Methods: A systematic review of the literature was performed in the PubMed and Embase databases in December 2013. A 'free-text' protocol using the term 'radical prostatectomy' was applied. A total of 16,085 records were found. The authors reviewed the records to identify comparative studies to include in the review. Results: 44 comparative studies were identified. With regard to the perioperative outcome, LRP and RALP were more time-consuming than RRP, but blood loss, transfusion rates, catheterisation time, hospitalisation duration, and complication rates were the most optimal in the laparoscopic approaches. With regard to the functional and oncological results, RALP was found to have the best outcomes. Conclusion: Our study confirmed the well-known perioperative advantage of minimally invasive techniques; however, available data were not sufficient to prove the superiority of any surgical approach in terms of functional and oncologic outcomes. On the contrary, cost comparison clearly supports RRP. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objective: Laparoscopic nephroureterectomy (LNU) offers a superior morbidity profile compared with open nephroureterectomy (ONU) in treating upper urinary tract urothelial cell carcinoma. Evidence of oncological equivalence between LNU and ONU is limited. We compare operative and oncological outcomes for LNU and ONU using matched-pair analysis. Methods: Of 159 patients who underwent a nephroureterectomy at a single institution between April 1992 and April 2010, 13 pairs of ONU and LNU patients were matched for gender, age, tumour location, tumour grade and stage. Operative details, post-operative characteristics and recurrences were collated and survival rates analysed using the Kaplan-Meier method. Results: There was no significant difference in mean operation time between LNU (191 min) and ONU (194 min, p = 0.92). There was no significant difference in the 5-year survival rate between LNU and ONU (overall survival 59.1% vs. 73.5%, p = 0.18; progression-free survival 24.0% vs. 56.0%, p = 0.14; cancer-specific survival 60.9% vs. 73.5%, p = 0.56; bladder cancer recurrence-free survival 8.7% vs. 0.0%, p = 0.09). Conclusion: Amidst limited RCT and comparative studies, this study presents further evidence of oncological equivalence between LNU and ONU. There was a trend towards poorer outcomes following LNU though, which merits further study. © 2014 S. Karger AG, Basel.

    ABSTRACT: Objective: To directly compare the diagnostic performance of targeted MRI-guided biopsy (MR-GB) and systematic transrectal ultrasound-guided biopsy (TRUS-GB). Methods: Thirty-five patients with at least one negative TRUS-GB, persistently elevated or rising prostate-specific antigen and a lesion suspicious for prostate cancer (PC) on multiparametric MRI (mpMRI) scored by using the Prostate Imaging Reporting and Data System (PI-RADS) were included. A median of three targeted biopsies per lesion were obtained and systematic TRUS-GB was performed subsequently by an independent urologist without knowledge of the MRI findings. Definite pathology reports were analyzed for anatomical location and criteria of clinical significance. Results: The tumor detection rate was significantly higher with MR-GB compared with TRUS-GB (16/35, 46% and 8/35, 23%, respectively, p < 0.05). MR-GB detected PC in all patients with positive TRUS-GB. All tumors detected by MR-GB exhibited at least one criterion of clinical significance. PC lesions showed a significantly higher PI-RADS sum score compared with benign lesions. Conclusions: MR-GB is more effective compared with TRUS-GB in detecting clinically significant PC in men after previous negative TRUS-GB. PI-RADS scores give additional information and could be part of the decision-making process when considering retrial biopsy. Additional systematic biopsy can be omitted in patients undergoing targeted MR-GB. © 2014 S. Karger AG, Basel.

    ABSTRACT: Introduction: Aberrant methylation levels in the cytosine-phosphate-guanine island (CpGi) region from exon 1 to intron 1 of the zygote arrest 1 (ZAR1) gene have been reported in several types of human cancers, including melanoma, brain tumor, and hepatocellular carcinoma. In the present study, methylation levels at the CpGi of ZAR1 exon 1/intron 1 in bladder cancer specimens were analyzed using mass spectrometry. Materials and Methods: Genomic DNA was extracted from 20 sporadic bladder cancers, and the methylation levels at ZAR1 CpGi were quantitatively examined by the MassARRAY EpiTYPER method. Result: The methylation levels at specific CpG sites of the ZAR1 CpGi were significantly lower in high-grade bladder cancers than in low-grade tumors. Conclusions: The results of the present study indicated a decreased methylation level at CpG sites of ZAR1 exon 1/intron 1. CpGi could serve as a biomarker for invasive bladder cancer. © 2014 S.

    ABSTRACT: Objective: Increased pneumoperitoneum pressure during laparoscopic surgery can result in acute kidney injury. We aimed to clarify whether intraabdominal pressure tolerance is modified in various degrees of unilateral kidney hydronephrosis in rabbits. Methods: A total 90 rabbits were randomly allocated to three groups (group PN, PM and PS, i.e. rabbits with no, mild and severe hydronephrosis, respectively, subjected to intraabdominal pressures). Rabbits in group PM (n = 30) and group PS (n = 30) underwent a surgical procedure inducing a mild or severe left hydronephrosis. Rabbits in all groups were then allocated to 5 subgroups. Then, they were subjected to intraabdominal pressures of 0, 6, 9, 12, and 15 mm Hg, respectively. Acute kidney injury was assessed by measuring serum creatinine (Scr), blood urea nitrogen (BUN), tubular cell apoptosis, kidney injury molecule-1 (KIM-1) and cysteine-rich 61 (Cyr-61/CCN1) expression. Results: Acute kidney injury with increased tubular apoptosis and KIM-1 and Cyr-61 expression occurred when intraabdominal pressure reached 15, 15 and 9 mm Hg in PN, PM and PS groups, respectively. The Scr and BUN levels were similar in all groups. Conclusions: In rabbits, kidneys with severe hydronephrosis were more likely to suffer acute injury when they were exposed to pneumoperitoneal pressure. © 2014 S. Karger AG, Basel.
