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: Pseudoaneurysm following flexible ureterorenoscopy has not been reported so far. The etiology remains unclear as high intra-renal pressure, direct laser damage and damage through stiff guidewire puncture had all been avoided. We like to share this case to make urologists aware of this unusual complication and discuss possible causes and therapeutic approaches.

    ABSTRACT: Introduction: With safe obstetric practices now globally available, most vesico-vaginal fistulas (VVF) presenting in recent times are secondary to various gynecologic surgeries. Most of them are supra-trigonal in location. Laparoscopic repair of VVF is gaining ground as an alternative to open repair of VVF. In this study, we describe our initial experience with a novel technique of laparoscopic VVF repair involving a limited transverse cystotomy for access and a single-layered barbed suture closure of bladder. Materials and methods: Twenty cases of supra-trigonal VVFs following gynecologic surgeries were taken up for repair by our novel technique. The mean age of the patients was 32 years and the mean VVF size was 1.5 cm. Results: The mean operative time was 54 min. Estimated mean blood loss was 30 ml and the mean postoperative stay was 2.5 days. None of the patients had any recurrence with a mean follow-up of 14 months. Conclusion: The limited transverse cystotomy approach has advantages in decreasing the operative time, improving ease of laparoscopic suturing, allowing an automatic separation of suture lines and allowing for an easier anterior dissection of the bladder to reduce tension on the suture line if necessary. Further this approach provides excellent results in select patients of supra-trigonal VVF in terms of continence and postoperative bladder overactivity.

    ABSTRACT: Aim: To investigate the safety, surgical efficiency and patients' ability to recover from urinary continence as a result of a single absorbable running suture versus single-knot running suture for vesicourethral anastomosis (VUA) during laparoscopic radical prostatectomy (LRP). Material and Methods: In a prospective randomised study, we evaluated 162 consecutive patients who underwent LRP with VUA using the single running suture technique or the single-knot running suture technique. Perioperative patients' characteristics, morbidity and urinary continence were analysed. Results: The baseline characteristics were similar between the 2 groups. The single running suture technique was related to decreased anastomotic and total operative times compared with the Van Velthoven technique (13.17 ± 5.74 min vs. 28.49 ± 6.45 min, p = 0.0001, and 174.41 ± 62.97 min and 184.94 ± 46.16 min, p = 0.04, respectively). Overall, urinary continence rates at 3, 6 and 12 months in groups 1 and 2 were 49.4 and 69.1%, 81.5 and 86.4%, and 91.4 and 93.8%, respectively (all with p > 0.05 except the follow-up assessment at 3 months following surgery, p = 0.011). Conclusions: Both methods ensure satisfactory rates of urinary leakage and bladder neck stricture, as well as continence after LRP. However, since the single running suture VUA technique is easier to perform, and the mean anastomosis time of the single running suture VUA technique is shorter than that of the Van Velthoven technique, it appears, therefore, preferable.

    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.

    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: 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.

    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.

    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.

    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.

    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.

    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.
