    ABSTRACT: To determine the efficacy and safety of flexible ureterorenoscopy (fURS) for the treatment of single intrarenal calculi and further stratify the efficacy by stone burden. CROES collected prospective data on consecutive patients with urinary stones treated with URS at 114 centers worldwide for 1 year. Only patients who underwent fURS for a solitary renal stone where included in the present study. Pre- and intraoperative characteristics, and post- operative outcomes were evaluated. The relationships between stone size and stone-free rate (SFR), operative time, complications, hospital stay, and need for retreatment were explored. and limitations: A total of 1210 patients with solitary kidney stones <10mm (52.2%), 10-20mm (43.2%) and >20mm (4.6%) were treated with fURS. There was a negative correlation between SFR and stone size when adjusted for BMI. Operating time showed a positive correlation with stone size when adjusted for BMI. Single session SFR was 90% for stones <10mm and 80% for stones <15 mm. Patients with stones >20mm achieved a 30% SFR, more often needed retreatment and were more often readmitted. There were no differences in overall complication rates for different stone sizes. However, patients with a stone >20mm had a higher probability of developing fever after fURS as compared to patients with smaller stones. Our data indicate that fURS for a single intrarenal stone is a safe procedure. Best results after single session fURS were obtained for stones <15mm.

    ABSTRACT: The aim of the present review was to compare state‐of‐the‐art care and future perspectives for the detection and treatment of non‐muscle‐invasive transitional cell carcinoma (TCC) of the bladder. We provide a summary of the third expert meeting on ‘Optimising the management of non‐muscle‐invasive bladder cancer, organized by the European Association of Urology Section for Uro‐Technology (ESUT) in collaboration with the Section for Uro‐Oncology (ESOU), including a systematic literature review. The article includes a detailed discussion on the current and future perspectives for TCC, including photodynamic diagnosis, optical coherence tomography, narrow band imaging, the Storz Professional Image Enhancement system, magnification and high definition techniques. We also provide a detailed discussion of future surgical treatment options, including en bloc resection and tumour enucleation. Intensive research has been conducted to improve tumour detection and there are promising future perspectives, that require proven clinical efficacy. En bloc resection of bladder tumours may be advantageous, but is currently considered to be experimental.

    ABSTRACT: An optimum metabolic evaluation strategy for urinary stone patients has not been clearly defined. To evaluate the optimum strategy for metabolic stone evaluation and management to prevent recurrent urinary stones. Several databases were searched to identify studies on the metabolic evaluation and prevention of stone recurrence in urolithiasis patients. Special interest was given to the level of evidence in the existing literature. Reliable stone analysis and basic metabolic evaluation are highly recommended in all patients after stone passage (grade A). Every patient should be assigned to a low- or high-risk group for stone formation. It is highly recommended that low-risk stone formers follow general fluid and nutritional intake guidelines, as well as lifestyle-related preventative measures to reduce stone recurrences (grade A). High-risk stone formers should undergo specific metabolic evaluation with 24-h urine collection (grade A). More specifically, there is strong evidence to recommend pharmacological treatment of calcium oxalate stones in patients with specific abnormalities in urine composition (grades A and B). Treatment of calcium phosphate stones using thiazides is only highly recommended when hypercalciuria is present (grade A). In the presence of renal tubular acidosis (RTA), potassium citrate and/or thiazide are highly recommended based on the relative urinary risk factor (grade A or B). Recommendations for therapeutic measures for the remaining stone types are based on low evidence (grade C or B following panel consensus). Diagnostic and therapeutic algorithms are presented for all stone types based on the best level of existing evidence. Metabolic stone evaluation is highly recommended to prevent stone recurrences. In this report, we looked at how patients with urolithiasis should be evaluated and treated in order to prevent new stone formation. Stone type determination and specific blood and urine analysis are needed to guide patient treatment. Copyright © 2014 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    ABSTRACT: The simultaneous surgical management of ureteropelvic junction obstruction (UPJO) with concomitant renal stones has evolved the last 20 years; hence, the ideal minimally invasive technique is still controversial. Laparoscopic and robot-assisted laparoscopic operations allow precise surgical maneuvers and were thought to simplify the reconstruction steps of the procedure, especially in the treatment of complex cases with large stones. The aim of this study was to summarize the available perioperative and functional outcomes of minimally invasive available techniques. A non-systematic review of the literature was performed using a free-text protocol in the MEDLINE database. The terms used were "ureteropelvic junction obstruction," "renal calculi" and "renal stones." Furthermore, other significant relevant studies cited in the reference lists of the selected papers were also evaluated in the structure of this review. Currently, available evidence suggests that both laparoscopic and robotic-assisted techniques offer excellent surgical solutions in the field of UPJO reconstruction and renal stones removal. In the hands of experienced surgeons, laparoscopic and robotic pyeloplasty with concomitant stone removal is a safe procedure with high stone-free rates and UPJ patency. Minimally invasive pyeloplasty should constitute the first choice of treatment for concomitant renal stones and ureteropelvic junction obstruction.

    ABSTRACT: Purpose: To examine the safety and efficacy of hyperbaric oxygen as the primary treatment for Grade IV radiation-induced haemorrhagic cystitis. Materials and Methods: Hyperbaric oxygen was prospectively applied as a primary treatment option in 11 patients with Grade IV radiation cystitis. Primary endpoint was the incidence of complete and partial response to treatment. Secondary endpoints included the duration of response, the correlation of treatment success-rate to the interval between the onset of haematuria and initiation of therapy, blood transfusion need and total radiation dose, the number of sessions to success, the avoidance of surgery and the overall survival. Results: All patients completed therapy without complications for a mean follow-up of 17.82 months (range 3 to 34). Mean number of sessions needed was 32.8 (range 27 to 44). Complete and partial response rate was 81.8% and 18.2%, respectively. However, in three patients the first treatment session was not either sufficient or durable giving a 72.7% rate of durable effect. Interestingly, all 9 patients with complete response received therapy within 6 months of the haematuria onset compared to the two patients with partial response who received therapy at 8 and 10 months from the haematuria onset, respectively (p = 0.018). The need for blood transfusion (p = 0.491) and the total radiation dose (p = 0.259) were not correlated to success-rate. One patient needed cystectomy, while all patients were alive at the end of follow-up. Conclusions: Early primary use of hyperbaric oxygen to treat radiation-induced grade IV cystitis is an effective and safe treatment option.

    ABSTRACT: To properly use the Ureteric Symptom Score Questionnaire (USSQ) to evaluate, in a randomized control study, the effect of 2 different α-blockers in improving symptoms and quality of life in patients with indwelling ureteral stents. After institutional review board approval, 150 consecutive patients with a double-J ureteral stent inserted after extracorporeal shockwave lithotripsy (ESWL) or ureteroscopic stone treatment were randomly assigned to receive tamsulosin 0.4 mg, alfuzosin 10 mg, or placebo. The validated USSQ was completed 1 and 4 weeks after stent insertion and 4 weeks after stent removal. The Kruskal-Wallis test for independent samples for non-normally distributed ordinal variables, chi-square to compare proportions or differences, and 1-way analysis of variance (ANOVA) for independent samples to compare for differences in case of continuous variables were used for statistical analysis of the results. Patients receiving α-blockers expressed an overall statistically significant lower urinary (P <.001), pain (P <.001 with stent in situ), and general health index (P <.002) scores. Sexual life and quality of life were also positively influenced. Quality of work was not influenced. No patients had to discontinue medication because of side effects or underwent stent removal before the due date. There was no difference in various outcomes between the 2 α-blockers. Stent-related morbidity is a reality in the majority of patients. Simple medication, such as α-blockers, reduce stent-related symptoms and the negative impact on quality of life. It seems that stent-related symptom improvement is independent to the type of α-blocker.

    ABSTRACT: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The effect of TURP on overall sexual function and particularly erectile function (EF) is controversial with conflicting results based on a low level of evidence. The effects of monopolar and bipolar TURP (M-TURP and B-TURP, respectively) on EF are similar, as has been shown in a few non-focused randomized control trials (RCTs). For the first time, the present study offers focused results of a comparative evaluation of the effects of B-TURP and M-TURP on overall sexual function, as quantified with the International Index of Erectile Function Questionnaire (IIEF-15) in an international, multicentre, double-blind RCT setting. OBJECTIVE: To compare monopolar and bipolar transurethral resection of the prostate (M-TURP and B-TURP, respectively) using a true bipolar system, for the first time in an international multicentre double-blind randomized controlled trial focusing on the overall sexual function quantified with the International Index of Erectile Function Questionnaire (IIEF-15). Other baseline/perioperative parameters potentially influencing erectile function (EF) after TURP were secondarily investigated. MATERIALS AND METHODS: From July 2006 to June 2009, consecutive TURP candidates with benign prostatic obstruction were prospectively recruited in four academic urological centres, randomized 1:1 into M-TURP/B-TURP arms and followed up at 6 weeks, 6 and 12 months after surgery. In all, 295 eligible patients were enrolled. Overall sexual function was quantified using self-administered IIEF-15 at baseline and at each subsequent visit. Total IIEF/domain scores were calculated and EF score classified erectile dysfunction severity. Differences in erectile dysfunction severity at each visit compared with baseline (EF evolution), classified patients into 'improved', 'stable' or 'deteriorated'. Pre-postoperative IIEF/domain scores and differences in the distribution of EF evolution were compared between arms throughout follow-up. RESULTS: In all, 279 patients received the allocated intervention; 218/279 patients (78.1%) provided complete IIEF-15 data at baseline and were considered in sexual function analysis. Complete IIEF-15 data were available from 193/218 (88.5%), 186/218 (85.3%) and 179/218 (82.1%) patients at 6 weeks, 6 months and 12 months, respectively. Sexual function did not differ significantly between arms during follow-up (scores: IIEF, P = 0.750; EF, P = 0.636; orgasmic function, P = 0.868; sexual desire, P = 0.735; intercourse satisfaction, P = 0.917; overall satisfaction, P = 0.927). Resection type was not a predictor of any sexual function changes observed. Distribution of EF evolution did not differ between arms at any time (M-TURP vs B-TURP at 12 months: improved, 23/87 [26.4%] vs 18/92 [19.6%]; stable, 53/87 [60.9%] vs 56/92 [60.8%]; deteriorated, 11/87 [12.7%] vs 18/92 [19.6%]; P = 0.323). CONCLUSION: There were no differences between M-TURP/B-TURP in any aspect of sexual function.

    ABSTRACT: Nowadays, rigid and flexible ureteroscopy is a precise, minimal invasive surgery that can assess the entire collecting system in order to treat a stone with intracorporeal lithotripsy. The implication of laser technology has revolutionized the intracorporeal lithotripsy. Currently, laser lithotripsy is advancing in two different directions: improvements of the existing Ho:YAG laser platform and the development of novel laser systems. Herein, we review the current literature upon intracorporeal lithotripsy.

    ABSTRACT: BACKGROUND: Pooled data from randomised controlled trials (RCTs) with short-term follow-up have shown a safety advantage for bipolar transurethral resection of the prostate (B-TURP) compared with monopolar TURP (M-TURP). However, RCTs with follow-up >12 mo are scarce. OBJECTIVE: To compare the midterm safety/efficacy of B-TURP versus M-TURP. DESIGN, SETTING, AND PARTICIPANTS: From July 2006 to June 2009, TURP candidates with benign prostatic obstruction were consecutively recruited in four centres, randomised 1:1 into the M-TURP or the B-TURP arm and regularly followed up to 36 mo postoperatively. A total of 295 patients were enrolled. INTERVENTION: M-TURP or B-TURP using the AUTOCON II 400 electrosurgical unit. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Safety was estimated by complication rates with a special emphasis on urethral strictures (US) and bladder neck contractures (BNCs) recorded during the short-term (up to 12 mo) and midterm (up to 36 mo) follow-up. Efficacy quantified by changes in maximum urine flow rate, postvoid residual urine volume, and International Prostate Symptom Score was compared with baseline, and reintervention rates in each arm were also evaluated. RESULTS AND LIMITATIONS: A total of 279 patients received treatment after allocation. Mean follow-up was 28.8 mo. A total of 186 of 279 patients (66.7%) completed the 36-mo follow-up. Posttreatment withdrawal rates did not differ significantly between arms. Safety was assessed in 230 patients (82.4%) at a mean follow-up of 33.4 mo. Ten US cases were seen in each arm (M-TURP vs B-TURP: 9.3% vs 8.2%; p=0.959); two versus eight BNC cases (M-TURP vs B-TURP: 1.9% vs 6.6%; p=0.108) were collectively detected at the midterm follow-up. Resection type was not a significant predictor of the risk of US/BNC formation. Efficacy was similar between arms and durable. A total of 10 of 230 patients (4.3%) experienced failure to cure and needed reintervention without significant differences between arms. High overall reintervention rates, withdrawal rates, and sample size determination not based on US/BNC rates represent potential limitations. CONCLUSIONS: The midterm safety and efficacy of B-TURP and M-TURP are comparable. TRIAL REGISTRATION: Netherlands Trial Register, NTR703 (

    ABSTRACT: INTRODUCTION: Acquired bladder diverticula (BD) in men over the age of 60 are usually due to bladder outlet obstruction (BOO) secondary to prostatic enlargement. In cases of clinical significant BD with persistent symptoms or complications surgical excision should be considered. In the treatment of BD it is important to address the BOO with a bladder outlet procedure either simultaneously or in a staged fashion. PRESENTATION OF CASE: We present to the best of our knowledge, the first case of sequential robotic-assisted bladder diverticulectomy (RABD) combined with robotic-assisted radical prostatectomy (RARP) in a patient with large diverticula and malignant prostate enlargement as the cause of BOO. DISCUSSION: Concomitant open radical prostatectomy and bladder diverticulectomy series have been described, while minimal invasive procedures combining BD excision with relive of BOO especially due to benign prostatic enlargement have been reported to be safe and effective. CONCLUSION: Concomitant RABD with RARP is a safe and effective procedure with excellent oncological and functional results.

    ABSTRACT: Urinary retention (UR) secondary to benign prostatic hyperplasia often leads patients to surgery, especially those who fail to urinate following a trial without catheter (TWOC). However, patients of high surgical risk and/or elderly patients with co-morbidities are usually not eligible for surgical treatment. Moreover, recurrent UR may indicate a poor detrusor function representing a risk factor of surgical therapy failure. Our objective was to evaluate the role of distigmine bromide, an anticholinesterase agent, to promote a successful TWOC in patients with recurrent UR. Seventeen elderly and/or high surgical-risk patients with recurrent UR and prior failures to TWOCs received a combination of alpha-blocker along with distigmine bromide and have been retrospectively compared with that of 20 first-time UR patients who received only the alpha-blocker just after emergency catheterization. The short-term outcome was measured by resumption of voiding, number of TWOC failures preceding successful voiding, determination of post-voiding residual volume (PVR), and International Prostate Symptom Score (IPSS). The majority of patients on combination therapy had a successful TWOC, similarly to all first-time urinary retention patients. Compared to patients on monotherapy, patients on combination therapy needed more TWOCs to void due to gradual increase in the dosage of distigmine bromide. PVR was significantly reduced with treatment in both groups. Statistically, there was no significant difference between the two groups on the PVR and IPSS mean change. Our results suggest that the combination of alpha-blocker and distigmine may eventually benefit patients with recurrent UR and prior unsuccessful TWOCs, to void.

    ABSTRACT: To review the current literature on intracorporeal laser lithotripsy.Methods We searched PubMed for relevant reports up to January 2012, using the keywords ‘laser’, ‘lithotripsy’ and ‘intracorporeal’.ResultsWe studied 125 relevant reports of studies with various levels of evidence. Efficient lithotripsy depends on the laser variables (wavelength, pulse duration and pulse energy) and the physical properties of the stones (optical, mechanical and chemical). The most efficient laser for stones in all locations and of all mineral compositions is the holmium yttrium–aluminium–garnet laser (Ho:YAG). The frequency-doubled double-pulse Nd:YAG laser functions through the generation of a plasma bubble. New laser systems, such as the erbium:YAG and the thulium laser, are under evaluation. Laser protection systems have also been developed for the novel digital flexible ureteroscopes. Although complications are rare, a high relevant clinical suspicion is necessary.Conclusions Laser lithotripsy technology is continuously developing, while the Ho:YAG laser remains the reference standard for intracorporeal lithotripsy.

    ABSTRACT: To evaluate the effect of hexaminolevulinate (HAL)-induced fluorescence during resection of noninvasive bladder cancer on tumor recurrence compared with resection under white light. Between 2008 and 2010, 102 consecutive patients with suspected bladder cancer were randomized to undergo transurethral resection with either conventional white light or combination of white light and HAL-induced fluorescence. Difference in tumor recurrence rate and recurrence-free survival between the 2 groups was evaluated. Subgroup analysis on recurrence-free survival was performed for different tumor parameters. Cystoscopy at 3 months revealed tumor recurrence in 6 of 45 (13.3%) patients of the white light group compared with only 1 of 41 patients of the HAL group (2.4%) (P < .001). The recurrence-free rates in white light patients at 12 and 18 months were 56.3% and 50.6%, respectively, compared with 91% and 82.5% in HAL patients (P = .0006). In subgroup analyses, recurrence-free survival was similar between the 2 groups when solitary tumors were treated (P = .3525). However, the HAL group had a favorable recurrence-free survival compared with the white light group when multifocal tumors (P < .001), primary tumors (P = .0237), recurrent tumors (P = .0189), nonaggressive (papillary urothelial neoplasm of low malignant potential and low grade) tumors (P = .0204), or aggressive (high grade and carcinoma in situ) tumors (P = .0134) were treated. HAL significantly aids resection of non-muscle-invasive bladder cancer with the result of reduction in tumor recurrence rates.

    ABSTRACT: Current guidelines recommend prophylactic antibiotic therapy for all patients undergoing percutaneous nephrolithotomy. We examined the effects of antibiotic prophylaxis in patients undergoing percutaneous nephrolithotomy with negative preoperative urine cultures. Of the 5,803 patients in the CROES (Clinical Research Office of the Endourological Society) Percutaneous Nephrolithotomy Global Study database, a group of 162 patients undergoing percutaneous nephrolithotomy with a negative baseline urine culture who did not receive antibiotic prophylaxis were matched on preoperative nephrostomy, the presence of staghorn calculi and diabetes status with an equal number of patients who received antibiotic prophylaxis. Comparisons were made between the 2 groups in terms of operative and postoperative outcomes, including the incidence of fever and other complications. Patients who received antibiotic prophylaxis had a lower mean (SD) age at 44.9 (14.2) vs 50.1 (14.4) years (p = 0.001). They were also more likely to be in the prone position during the procedure (71.6% vs 39.5%, p <0.001) but less likely to receive postoperative stenting (17.3% vs 32.7%, p = 0.002) than those who did not receive prophylaxis. The 2 groups were comparable in terms of all other baseline characteristics and operative factors. Patients who received antibiotic prophylaxis were less likely to experience fever (2.5% vs 7.4%, p = 0.040) and other postoperative complications (1.9% vs 22.0%, p <0.0001), and had a higher stone-free rate after percutaneous nephrolithotomy (86.3% vs 74.4%, p = 0.006). Antibiotic prophylaxis of patients undergoing percutaneous nephrolithotomy with a negative baseline urine culture is associated with a significant reduction in the rate of postoperative fever and other complications.
