Joint consensus on anesthesia in urologic and gynecologic robotic surgery: specific issues in management from a task force of the SIAARTI, SIGO, and SIU.

INTRODUCTION: Proper management of patients undergoing robotic-assisted urologic and gynecologic surgery must consider a series of peculiarities in the procedures for anesthesiology, critical care medicine, respiratory care, and pain management. Although the indications for robotic-assisted urogynecologic surgeries have increased in recent years, specific guidance documents are still lacking. EVIDENCE ACQUISITION: A multidisciplinary group including anesthesiologists, gynecologists, urologists, and a clinical epidemiologist systematically reviewed the relevant literature and provided a set of recommendations and unmet needs on peculiar aspects of anesthesia in this field. EVIDENCE SYNTHESIS: Nine core contents were identified, according to their requirements in urogynecologic robotic-assisted surgery: patient position, pneumoperitoneum and ventilation strategies, hemodynamic variations and fluid therapy, neuromuscular block, renal surgery and prevention of acute kidney injury, monitoring the Department of anesthesia, postoperative delirium and cognitive dysfunction, prevention of postoperative nausea and vomiting, and pain management in endometriosis. CONCLUSIONS: This consensus document provides guidance for the management of urologic and gynecologic patients scheduled for robotic-assisted surgery. Moreover, the identified unmet needs highlight the requirement for further prospective randomized studies.

Endoscopic Intravesical Fibrin Glue Application in the Treatment of Refractory Hemorrhagic Radiation Cystitis: A Single Cohort Pilot Study.

OBJECTIVE: To evaluate the clinical value of endoscopic fibrin glue (FG) application therapy in treating hemorrhagic radiation cystitis (HRC). PATIENTS AND METHODS: This is a single-cohort, prospective pilot study. We collected data from patients with HRC who were treated at our urology unit from May 2014 to December 2016. Patients with grade ≥2 HRC for whom conventional therapy and transurethral endoscopic electrocoagulation had failed were treated with endoscopic intravesical FG. The mean follow-up was 26.2 ± 9.78 months. Our analysis included data on patient demographics, pelvic malignancies, radiotherapy regimens, total dose of radiation received, time of onset and severity of hematuria, and previous intravesical management. Following FG intervention, patients' clinical status was defined as: (1) clinical response; absence of dysuria, urgency, and frequency; discontinuation of analgesic medication; and Foley catheter removal, but with ongoing hematuria grade <2; (2) complete response, clinical response, and no further hematuria; or (3) no response, no clinical response, and sustained hematuria. RESULTS: A total of 20 patients (12 women and 8 men; mean age, 69 ± 7.5 years) were treated with 12 mL FG intravesically, using endoscopic application. Of the 20 patients, 16 (80%) had a complete response and 4 (20%) had a clinical response. In the case of four patients (20%), treatment was carried out twice. Mean hospital stay was 6 ± 2.5 days. The intervention showed good tolerability in all patients. No major adverse events were reported. Bladder spasms were the only minor adverse events reported in six patients (30%). CONCLUSION: Application of FG is an effective, practical, affordable, and repeatable procedure for the treatment of grade ≥2 HRC.

Serenoa repens + selenium + lycopene vs tadalafil 5 mg for the treatment of lower urinary tract symptoms secondary to benign prostatic obstruction: a Phase IV, non-inferiority, open-label, clinical study (SPRITE study).

OBJECTIVE: To compare in a randomised, open-label, non-inferiority clinical study, the efficacy and tolerability of Serenoa repens (SeR) + selenium (Se) + lycopene (Ly) (SeR-Se-Ly) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: From May 2015 to January 2017, 427 patients were enrolled in 21 different centres (International Standard Randomised Controlled Trial Number Register [ISRCTN] 73316039). Inclusion criteria included: age between 50 and 80 years, International Prostate Symptom Score (IPSS) ≥12, maximum urinary flow rate (Qmax ) ≤ 15 mL/s, and post-void residual (PVR) <100 mL. Patients were randomised into two groups in a 2:1 ratio: Group A (SeR-Se-Ly, 1 tablet daily for 6 months) and Group B (tadalafil 5 mg, 1 tablet daily for 6 months). The primary endpoint of the study was the non-inferior variation in the IPSS and Qmax in Group A vs Group B after 6 months of treatment. RESULTS: In all, 404 patients completed the full protocol. When comparing both therapies, Group A was statistically not inferior to Group B considering the median change in IPSS (-3.0 vs -3.0; P < 0.01), IPSS quality of life (-2.0 vs -2.0; P < 0.05), and Qmax (2.0 vs 2.0 mL/s; P < 0.01). We found statistically significant differences in the increase of at least 3 points in Qmax (38.2% vs 28.1%; P = 0.04) and of at least 30% of Qmax (39.2% vs 27.3%; P < 0.01) in Group A compared to Group B. The percentage of patients with an increase of at least 3 points in the IPSS and a decrease of at least 25% of the IPSS was not statistically different between the two groups. For adverse events, four patients in Group A (1.44%) and 10 in Group B (7.81%) (P < 0.05) reported side-effects. CONCLUSION: We have shown that treatment with SeR-Se-Ly was not inferior to tadalafil 5 mg for improving IPSS and Qmax in men with LUTS.

Association between selenium and lycopene supplementation and incidence of prostate cancer: Results from the post-hoc analysis of the procomb trial.

BACKGROUND: Many potential chemopreventive agents have been used in PCa prevention, including selenium (Se) and lycopene (Ly). However, their role has been matter of debate over the years, due to potential of promotion of PCa. PURPOSE: In this study we aimed at evaluating the incidence risk of prostate cancer (PCa) in a cohort of patients treated with Se and Ly. METHODS: The Procomb trial design has been previously published (ISRCTN78639965). From April 2012 to April 2014 209 patients were followed and underwent prostate biopsy when PSA ≥4 ng/ml and/or suspicion of PCa. The all cohort was composed by patients treated with Se and Ly (Group A = 134 patients) and control (Group B = 75 patients). RESULTS: During the follow-up time of 2 years, a total of 24 patients (11.5%) underwent prostate biopsy, of which 9 (4.3%) where diagnosed with PCa and 15 (7.2%) where diagnosed with benign prostatic hyperplasia. We did not observe statistical differences in terms of mean changes of PSA between the two groups (p-value for trend = 0.33). The relative risk (RR) for PCa was 1.07 and 0.89 in group A and B, respectively (p = 0.95). At the multivariate Cox regression analysis supplementation with Se and Ly was not associated with greater risk of PCa (hazard ratio: 1.38; p = 0.67). CONCLUSION: In this analysis we did not show evidences supporting a detrimental role of Selenium and Lycopene supplementation in increasing PCa after 2 years of therapy, nor supporting a protective role.

Partial renal resection by LaparoNewPro: in vivo open and laparoscopic study in an animal model.

INTRODUCTION: The aim of this research project was to test an incremental bipolar radiofrequency generator with open and laparoscopic inline electrode probe for partial renal resection without vascular clamping. MATERIAL AND METHODS: Sixteen polar resections with clamping and six without were performed in four pigs in the acute phase. Three pigs underwent laparoscopic polar resection and were live housed for ten days and reoperated to verify the presence of hematic and urinary collection and the condition of the renal edge. Five pigs underwent laparoscopic polar resection without clamping, and two of these were live housed and reoperated after ten days. RESULTS: Polar renal resection by our system (LaparoNewPro) turned out to be effective and safe, without cardio-respiratory complications or damage to the remaining parenchyma. Coagulation of the renal parenchyma before resection is effective and safe; at the reoperation, no complications were observed. The laparoscopic version of the probe is ergonomic and safe, with effective coagulation and a small amount of smoke produced. No complications occurred in the housed animals. No damage, local or to residual parenchyma, or thrombosis of the renal vessels were found. CONCLUSIONS: LaparoNewPro is able to deliver coagulation of the resection line effectively and independently of clamping of the vessels both in the open and laparoscopic approaches. Coagulation times are short, the automatism of the generator is reliable, and the open and laparoscopic probes are ergonomic.

Microsurgical tunica albuginea transplantation in an animal model.

Several andrological diseases require surgical repair or reconstruction of tunica albuginea, which envelops the corpora cavernosa penis. Despite intense research efforts involving a variety of biological materials, such as skin, muscle aponeurosis, human dura mater, tunica vaginalis, and pericardium, engineered tunica albuginea suitable for graft use is yet to be obtained. The study investigates microsurgical tunica albuginea allotransplantation in an animal model with the purpose of creation of an organ-specific tissue bank to store penile tissue, from cadaveric donors and male-to-female trans-sexual surgery, for allogeneic transplantation. Materials were tunica albuginea tissue explanted from 15 donor rats, cryopreserved at -80°C, gamma-irradiated, and implanted in 15 recipient rats, of which three rats were used as controls. Penile grafts were explanted at different time intervals; after macroscopic evaluation of the organ, the grafts were processed to morphological, histochemical, and immunohistochemical examinations by light microscopy. Detection of pro-inflammatory cytokines was also performed. Examination of the tunica albuginea allografts collected 1, 3, or 6 months after surgery and of control tunica albuginea fragments showed that tunica albuginea implants achieved biointegration with adjacent tissue at all-time points. The integration of cryopreserved rat tunica albuginea allografts, documented by our study, encourages the exploration of tunica albuginea allotransplantation in humans. In conclusion, the effectiveness and reliability of the tunica albuginea conditioning protocol described here suggest the feasibility of setting up a tunica albuginea bank as a further tissue bank.

Risk factors for benign prostatic enlargement: The role of lifestyle habits at younger age. The #Controllati2017 initiative study group.

OBJECTIVE: The risk factors for benign prostatic enlargement (BPE) are not well understood and particularly few data are available from Italian population. MATERIALS AND METHODS: This was an observational cross sectional study aimed to examine the association between several risk factors and BPE. During the "#Controllati2017" initiative, men aged 18 years or more were invited to attend participating urologic centers for a free of charge visit for counseling about urologic or andrologic conditions. Each participating man underwent a physical examination including digital rectal examination (DRE). Further he was asked about his medical history, urologic symptoms, sexual activity and related problems. Diagnosis of BPE was made by the urologist after DRE. RESULTS: Out of the 1902 [mean age 54 years (SD 12, range 18-92)] considered men, a total of 603 subjects (31.7%) had diagnosis of BPE. The diagnosis of BPE increased from 9.3% in men aged < = 50 years, to 34.1% in those aged 51-60 years and to 58.7% among men aged > 60 years. A history of hypertension, diabetes, heart diseases, hypercholesterolemia and hypertriglyceridemia were all significantly associated with an increased risk of BPE in the total series and, although not always in a statistically significant way, in strata of age. Physical activity (PA) was significantly associated with a decreased risk of BPE. We have further analyzed the risk of BPE in men with one or more of the identified risk factors (i.e. hypertension, diabetes, heart disease, hypercholesterolemia, hypertriglyceridemia and low PA): the risk of BPE increased with number of risk factors reported by the subjects. The estimated risk were higher among younger men. CONCLUSION: In our study a history of hypertension, diabetes, heart disease, hypercholesterolemia and hypertriglyceridemia increased the risk and physical activity lowered the risk of BPE. This risk profile was observed also in men aged < 50 years.

Sexual outcomes after partial penectomy for penile cancer: results from a multi-institutional study.

Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients' sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25) represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25). Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15). Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15), orgasmic function (IIEF-9 and -10), sexual desire (IIEF-11 and -12), intercourse satisfaction (IIEF-6-8), and overall satisfaction (IIEF-13 and -14). Then, we also used Quality of Erection Questionnaire (QEQ), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and Self-Esteem and Relationship (SEAR) to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

Ellagic Acid Inhibits Bladder Cancer Invasiveness and In Vivo Tumor Growth.

Ellagic acid (EA) is a polyphenolic compound that can be found as a naturally occurring hydrolysis product of ellagitannins in pomegranates, berries, grapes, green tea and nuts. Previous studies have reported the antitumor properties of EA mainly using in vitro models. No data are available about EA influence on bladder cancer cell invasion of the extracellular matrix triggered by vascular endothelial growth factor-A (VEGF-A), an angiogenic factor associated with disease progression and recurrence, and tumor growth in vivo. In this study, we have investigated EA activity against four different human bladder cancer cell lines (i.e., T24, UM-UC-3, 5637 and HT-1376) by in vitro proliferation tests (measuring metabolic and foci forming activity), invasion and chemotactic assays in response to VEGF-A and in vivo preclinical models in nude mice. Results indicate that EA exerts anti-proliferative effects as a single agent and enhances the antitumor activity of mitomycin C, which is commonly used for the treatment of bladder cancer. EA also inhibits tumor invasion and chemotaxis, specifically induced by VEGF-A, and reduces VEGFR-2 expression. Moreover, EA down-regulates the expression of programmed cell death ligand 1 (PD-L1), an immune checkpoint involved in immune escape. EA in vitro activity was confirmed by the results of in vivo studies showing a significant reduction of the growth rate, infiltrative behavior and tumor-associated angiogenesis of human bladder cancer xenografts. In conclusion, these results suggest that EA may have a potential role as an adjunct therapy for bladder cancer.

Prevalence of Cardiovascular Disease and Osteoporosis During Androgen Deprivation Therapy Prescription Discordant to EAU Guidelines: Results From a Multicenter, Cross-sectional Analysis From the CHOsIng Treatment for Prostate canCEr (CHOICE) Study.

OBJECTIVE: To analyze the prevalence of cardiovascular disease (CVD) and osteoporosis in patients treated with androgen deprivation therapy (ADT) for prostate cancer (PCa) but not adherent to European Association of Urology (EAU) guidelines. MATERIALS AND METHODS: The CHOosIng Treatment for Prostate CanCEr (CHOICE) study was an Italian multicenter, cross-sectional study conducted from December 2010 to January 2012. A total of 1386 patients treated with ADT for PCa (first prescription or renewal of ADT) were selected. According to EAU guidelines, the cohort was categorized in discordant ADT (Group A) and concordant ADT (Group B). The prevalence of CVD and osteoporosis after ADT was recorded. RESULTS: The final cohort included 1075 patients. According to EAU guidelines adherence, 285 (26.51%) and 790 (73.49%) were considered discordant and concordant, respectively. The proportion of men with Charlson Comorbidity Index > 2 at baseline was statistically similar in Group A (81.8%) compared to Group B (80.8%) (P = .96). The number of complications reported at enrollment was as follows: cardiovascular in 351 (32.7%), endocrine in 166 (15.4%), sexual in 498 (46.3%), osteoporosis in 181 (16.8%), and gynecomastia in 274 (25.5%) subjects. At the multivariate logistic regression analysis adjusted for confounding factors, discordant ADT was associated with greater risk of cardiovascular complications (odds ratio: 2.07; P < .01) and osteoporosis (odds ratio: 1.75; P = .04). CONCLUSION: About one-third of patients with PCa received inappropriate ADT and showed a greater risk of CVD and osteoporosis. These results could be useful for setting better policy strategies to limit the inappropriateness of ADT prescription.

Patterns of prescription and adherence to European Association of Urology guidelines on androgen deprivation therapy in prostate cancer: an Italian multicentre cross-sectional analysis from the Choosing Treatment for Prostate Cancer (CHOICE) study.

OBJECTIVE: To evaluate both the patterns of prescription of androgen deprivation therapy (ADT) in patients with prostate cancer (PCa) and the adherence to European Association of Urology (EAU) guidelines for ADT prescription. METHODS: The Choosing Treatment for Prostate Cancer (CHOICE) study was an Italian multicentre cross-sectional study conducted between December 2010 and January 2012. A total of 1 386 patients, treated with ADT for PCa (first prescription or renewal of ADT), were selected. With regard to the EAU guidelines on ADT, the cohort was categorized into discordant ADT (Group A) and concordant ADT (Group B). RESULTS: The final cohort included 1 075 patients with a geographical distribution including North Italy (n = 627, 58.3%), Central Italy (n = 233, 21.7%) and South Italy (n = 215, 20.0%). In the category of patients treated with primary ADT, a total of 125 patients (56.3%) were classified as low risk according to D'Amico classification. With regard to the EAU guidelines, 285 (26.51%) and 790 patients (73.49%) were classified as discordant (Group A) and concordant (Group B), respectively. In Group A, patients were more likely to receive primary ADT (57.5%, 164/285 patients) than radical prostatectomy (RP; 30.9%, 88/285 patients), radiation therapy (RT; 6.7%, 19/285 patients) or RP + RT (17.7%, 14/285 patients; P < 0.01). Multivariate logistic regression analysis, adjusted for clinical and pathological variables, showed that patients from Central Italy (odds ratio [OR] 2.86; P < 0.05) and South Italy (OR 2.65; P < 0.05) were more likely to receive discordant ADT. CONCLUSION: EAU guideline adherence for ADT was low in Italy and was influenced by geographic area. Healthcare providers and urologists should consider these results in order to quantify the inadequate use of ADT and to set policy strategies to overcome this risk.

Retzius-sparing robot-assisted laparoscopic radical prostatectomy: Critical appraisal of the anatomic landmarks for a complete intrafascial approach.

To provide an overview of the anatomical landmarks needed to guide a retropubic (Retzius)-sparing robot-assisted laparoscopic prostatectomy (RALP), and a step-by-step description of the surgical technique that maximizes preservation of the periprostatic neural network. The anatomy of the pelvic fossae is presented, including the recto-vesical pouch (pouch of Douglas) created by the reflections of the peritoneum. The actual technique of the trans-Douglas, intrafascial nerve-sparing robotic radical prostatectomy is described. The technique allows the prostate gland to be shelled out from under the overlying detrusor apron and dorsal vascular complex (DVC-Santorini plexus), entirely avoiding the pubovesical ligaments. There is no need to control the DVC, since the line of dissection passes beneath the plexus. Three key points to ensure enhanced nerve preservation should be respected: (1) the tips of the seminal vesicles, enclosed in a "cage" of neuronal tissue; a seminal vesicle-sparing technique is therefore advised when oncologically safe; (2) the external prostate-vesicular angle; (3) the lateral surface of the prostate gland and the apex. The principles of tension and energy-free dissection should guide all the maneuvers in order to minimize neuropathy. Using robotic technology, a complete intrafascial dissection of the prostate gland can be achieved through the Douglas space, reducing surgical trauma and providing excellent functional and oncological outcomes.

Dietary treatment of urinary risk factors for renal stone formation. A review of CLU Working Group.

OBJECTIVE: Diet interventions may reduce the risk of urinary stone formation and its recurrence, but there is no conclusive consensus in the literature regarding the effectiveness of dietary interventions and recommendations about specific diets for patients with urinary calculi. The aim of this study was to review the studies reporting the effects of different dietary interventions for the modification of urinary risk factors in patients with urinary stone disease. MATERIALS AND METHODS: A systematic search of the Pubmed database literature up to July 1, 2014 for studies on dietary treatment of urinary risk factors for urinary stone formation was conducted according to a methodology developed a priori. Studies were screened by titles and abstracts for eligibility. Data were extracted using a standardized form and the quality of evidence was assessed. RESULTS: Evidence from the selected studies were used to form evidence-based guideline statements. In the absence of sufficient evidence, additional statements were developed as expert opinions. CONCLUSIONS: General measures: Each patient with nephrolithiasis should undertake appropriate evaluation according to the knowledge of the calculus composition. Regardless of the underlying cause of the stone disease, a mainstay of conservative management is the forced increase in fluid intake to achieve a daily urine output of 2 liters. HYPERCALCIURIA: Dietary calcium restriction is not recommended for stone formers with nephrolithiasis. Diets with a calcium content ≥ 1 g/day (and low protein-low sodium) could be protective against the risk of stone formation in hypercalciuric stone forming adults. Moderate dietary salt restriction is useful in limiting urinary calcium excretion and thus may be helpful for primary and secondary prevention of nephrolithiasis. A low-normal protein intake decrease calciuria and could be useful in stone prevention and preservation of bone mass. Omega-3 fatty acids and bran of different origin decreases calciuria, but their impact on the urinary stone risk profile is uncertain. Sports beverage do not affect the urinary stone risk profile. HYPEROXALURIA: A diet low in oxalate and/or a calcium intake normal to high (800-1200 mg/day for adults) reduce the urinary excretion of oxalate, conversely a diet rich in oxalates and/or a diet low in calcium increase urinary oxalate. A restriction in protein intake may reduce the urinary excretion of oxalate although a vegetarian diet may lead to an increase in urinary oxalate. Adding bran to a diet low in oxalate cancels its effect of reducing urinary oxalate. Conversely, the addition of supplements of fruit and vegetables to a mixed diet does not involve an increased excretion of oxalate in the urine. The intake of pyridoxine reduces the excretion of oxalate. HYPERURICOSURIA: In patients with renal calcium stones the decrease of the urinary excretion of uric acid after restriction of dietary protein and purine is suggested although not clearly demonstrated. HYPOCITRATURIA: The administration of alkaline-citrates salts is recommended for the medical treatment of renal stone-formers with hypocitraturia, although compliance to this treatment is limited by gastrointestinal side effects and costs. Increased intake of fruit and vegetables (excluding those with high oxalate content) increases citrate excretion and involves a significant protection against the risk of stone formation. Citrus (lemons, oranges, grapefruit, and lime) and non citrus fruits (melon) are natural sources of dietary citrate, and several studies have shown the potential of these fruits and/or their juices in raising urine citrate levels. CHILDREN: There are enought basis to advice an adequate fluid intake also in children. Moderate dietary salt restriction and implementation of potassium intake are useful in limiting urinary calcium excretion whereas dietary calcium restriction is not recommended for children with nephrolithiasis. It seems reasonable to advice a balanced consumption of fruit and vegetables and a low consumption of chocolate and cola according to general nutritional guidelines, although no studies have assessed in pediatric stone formers the effect of fruit and vegetables supplementation on urinary citrate and the effects of chocolate and cola restriction on urinary oxalate in pediatric stone formers. Despite the low level of scientific evidence, a low-protein (< 20 g/day) low-salt (< 2 g/day) diet with high hydration (> 3 liters/day) is strongly advised in children with cystinuria. ELDERLY: In older patients dietary counseling for renal stone prevention has to consider some particular aspects of aging. A restriction of sodium intake in association with a higher intake of potassium, magnesium and citrate is advisable in order to reduce urinary risk factors for stone formation but also to prevent the loss of bone mass and the incidence of hypertension, although more hemodynamic sensitivity to sodium intake and decreased renal function of the elderly have to be considered. A diet rich in calcium (1200 mg/day) is useful to maintain skeletal wellness and to prevent kidney stones although an higher supplementation could involve an increase of risk for both the formation of kidney stones and cardiovascular diseases. A lower content of animal protein in association to an higher intake of plant products decrease the acid load and the excretion of uric acid has no particular contraindications in the elderly patients, although overall nutritional status has to be preserved.

Prevalence of "complicated" stress urinary incontinence in female patients: can urodynamics provide more information in such patients?

INTRODUCTION AND HYPOTHESIS: The role of urodynamic investigation has been recently questioned on the basis of data from a selected population of patients with stress urinary incontinence defined as uncomplicated. The aim of this study was to determine the proportion of patients who underwent urodynamic investigation in our centre in whom the stress urinary incontinence could be defined as uncomplicated. The secondary aim was to assess the number of women in whom the urodynamic investigation added information to the preurodynamic assessment. METHODS: This was a retrospective single-centre study. The data from female patients who underwent urodynamic evaluation prior to surgery for stress urinary incontinence between 2008 and 2012 were considered. Patients were categorized as presenting with uncomplicated or complicated stress urinary incontinence according to the definitions used in the ValUE trial. Urodynamic observations were then compared with preurodynamic data. RESULTS: Data from 244 female patients were considered. Due to incomplete data, 33 of these patients were excluded from the evaluation. Only 47 patients (22.3 %) were considered to have uncomplicated stress urinary incontinence according to the definition used in the ValUE trial. The remaining 164 patients (77.7 %) were considered to have complicated stress urinary incontinence. Urodynamic observations differed from the preurodynamic data in 134 of 211 patients (63.5 %). A diagnosis of voiding dysfunction was obtained in 25.6 % of patients. CONCLUSIONS: The majority of our patients had complicated stress urinary incontinence. In a relevant percentage of these patients, a urodynamic test added some new information, including a diagnosis of voiding dysfunction. The role of urodynamic investigation needs to be explored in this patient group.

3D vs 2D laparoscopic radical prostatectomy in organ-confined prostate cancer: comparison of operative data and pentafecta rates: a single cohort study.

BACKGROUND: Currently, men are younger at the time of diagnosis of prostate cancer and more interested in less invasive surgical approaches (traditional laparoscopy, 3D-laparoscopy, robotics). Outcomes of continence, erectile function, cancer cure, positive surgical margins and complication are well collected in the pentafecta rate. However, no comparative studies between 4th generation 3D-HD vision system laparoscopy and standard bi-dimensional laparoscopy have been reported. This study aimed to compare the operative, perioperative data and pentafecta rates between 2D and 3D laparoscopic radical prostatectomy (LRP) and to identify the actual role of 3D LRP in urology. METHODS: From October 2012 to July 2013, 86 patients with clinically localized prostate cancer [PCa: age ≤ 70 years, prostate-specific antigen (PSA) ≤ 10 ng/ml, biopsy Gleason score ≤ 7] underwent laparoscopic extraperitoneal radical prostatectomy (LERP) and were followed for approximately 14 months (range 12-25). Patients were selected for inclusion via hospital record data, and divided into two groups. Their patient records were then analyzed. Patients were randomized into two groups: the former 2D-LERP (43 pts) operated with the use of 2D-HD camera; the latter 3D-LERP (43 pts) operated with the use of a 3D-HD 4th generation view system. The operative and perioperative data and the pentafecta rates between 2D-LERP and 3D-LERP were compared. RESULTS: The overall pentafecta rates at 3 months were 47.4% and 49.6% in the 2D- and 3D-LERP group respectively. The pentafecta rate at 12 months was 62.7% and 67% for each group respectively. 4th generation 3D-HD vision system provides advantages over standard bi-dimensional view with regard to intraoperative steps. Our data suggest a trend of improvement in intraoperative blood loss and postoperative recovery of continence with the respect of the oncological safety. CONCLUSIONS: Use of the 3D technology by a single surgeon significantly enhances the possibility of achieving better intraoperative results and pentafecta in all patients undergoing LERP. Potency was the most difficult outcome to reach after surgery, and it was the main factor leading to pentafecta failure. Nevertheless, further studies are necessary to better comprehend the role of 3D-LERP in modern urology.

Laparoscopic pretransplant nephrectomy with morcellation in autosomic-dominant polycystic kidney disease patients with end-stage renal disease.

BACKGROUND: Laparoscopic nephrectomy (LN) in end-stage autosomic-dominant polycystic kidney disease (ADPKD) requires a large abdominal incision for the specimen extraction. OBJECTIVE: The objective of this study was to describe our technique of LN for end-stage ADPKD followed by morcellation (LNM) of the specimen and extraction through a minimal abdominal incision. METHODS: The medical records of 19 consecutive patients who underwent pretransplant LNM between 2008 and 2011 by a single experienced laparoscopic surgeon were analyzed. Morcellation was performed with the Gynecare Morcellex™ Tissue morcellator, Ethicon. RESULTS AND LIMITATIONS: All cases but one were completed laparoscopically. Mean specimen weight was 1,026.8 g. Mean duration of the procedure, estimated blood loss, and hospital stay were 131.3 min, 52.1 ml, and 7.9 days, respectively. Specimens were extracted through a 12-mm trocar in 10/18 patients and through a 3-cm incision in 9/18 cases. Postoperatively, three complications were observed (Clavien grades II, I, and II). The only case of incisional hernia was observed in the converted procedure. Major limitation of the study is its retrospective design. CONCLUSIONS: In our preliminary series and in the hands of a very experienced laparoscopist, LNM for ADPKD appears as a modern, mini-invasive, and safe technique. Specimen's extraction through a small abdominal incision reduces postoperative pain and incisional hernias and guarantees the final cosmetic result of laparoscopy. The reduced overall morbidity could reduce the period between nephrectomy and transplantation.

Correlation between penile cuff test and pressure-flow study in patients candidates for trans-urethral resection of prostate.

BACKGROUND: Aim of this study was to make a comparison between penile cuff test (PCT) and standard pressure-flow study (PFS) in the preoperative evaluation of patients candidates for trans-urethral resection of prostate (TURP) for benign prostatic obstruction (BPO). METHODS: We enrolled male patients with lower urinary tract symptoms candidates for TURP. Each of them underwent a PCT and a subsequent PFS. A statistical analysis was performed: sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), likelihood ratio and ratio of corrected classified were calculated. Fisher exact test was used to evaluate relationships between PCT and maximal urine flow (Qmax): a p-value < 0.05 was considered statistically significant. RESULTS: We enrolled 48 consecutive patients. Overall, at PCT 31 patients were diagnosed as obstructed and 17 patients as unobstructed. At the subsequent PFS, 21 out of 31 patients diagnosed as obstructed at PCT were confirmed to be obstructed; one was diagnosed as unobstructed; the remaining 9 patients appeared as equivocal. Concerning the 17 patients unobstructed at PCT, all of them were confirmed not to be obstructed at PFS, with 10 equivocal and 7 unobstructed. The rate of correctly classified patients at PCT was 79% (95%-CI 65%-90%). About detecting obstructed patients, PCT showed a SE of 100% and a SP of 63%. The PPV was 68%, while the NPV was 100%. CONCLUSIONS: PCT can be an efficient tool in evaluating patients candidates for TURP. In particular, it showed good reliability in ruling out BPO because of its high NPV, with a high rate of correctly classified patients overall. Further studies on a huger number of patients are needed, including post-operative follow-up as well.

Nosocomial urinary tract infections: A review.

Nosocomial urinary tract infections are a common complication in healthcare systems worldwide. A review of the literature was performed in June 2014 using the Medical Literature Analysis and Retrieval System Online (MEDLINE) database, through either PubMed or Ovid as a search engine, to identify publications regarding nosocomial urinary tract infections (NUTIs) definition, epidemiology, etiology and treatment.According to current definitions, more than 30% of nosocomial infections are urinary tract infections (UTIs). A UTI is defined 'nosocomial' (NUTI) when it is acquired in any healthcare institution or, more generally, when it is related to patient management. The origin of nosocomial bacteria is endogenous (the patient's flora) in two thirds of the cases. Patients with indwelling urinary catheters, those undergoing urological surgery and manipulations, long-stay elderly male patients and patients with debilitating diseases are at high risk of developing NUTIs. All bacterial NUTIs should be treated, whether the patient is harboring a urinary catheter or not. The length of treatment depends on the infection site. There is abundance of important guidance which should be considered to reduce the risk of NUTIs (hand disinfection with instant hand sanitizer, wearing non-sterile gloves permanently, isolation of infected or colonized catheterized patients). Patients with asymptomatic bacteriuria can generally be treated initially with catheter removal or catheter exchange, and do not necessarily need antimicrobial therapy. Symptomatic patients should receive antibiotic therapy. Resistance of urinary pathogens to common antibiotics is currently a topic of concern.

Acute kidney injury due to bilateral ureteral obstruction in children.

Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood.

Robotic radical nephrectomy for renal cell carcinoma: a systematic review.

BACKGROUND: Laparoscopic radical nephrectomy (LRN) is the actual gold-standard for the treatment of clinically localized renal cell carcinoma (RCC) (cT1-2 with no indications for nephron-sparing surgery). Limited evidence is currently available on the role of robotics in the field of radical nephrectomy. The aim of the current study was to provide a systematic review of the current evidence on the role of robotic radical nephrectomy (RRN) and to analyze the comparative studies between RRN and open nephrectomy (ON)/LRN. METHODS: A Medline search was performed between 2000-2013 with the terms "robotic radical nephrectomy", "robot-assisted laparoscopic nephrectomy", "radical nephrectomy". Six RRN case-series and four comparative studies between RRN and (ON)/pure or hand-assisted LRN were identified. RESULTS: Current literature produces a low level of evidence for RRN in the treatment of RCC, with only one prospective study available. Mean operative time (OT) ranges between 127.8-345 min, mean estimated blood loss (EBL) ranges between 100-273.6 ml, and mean hospital stay (HS) ranges between 1.2-4.3 days. The comparison between RRN and LRN showed no differences in the evaluated outcomes except for a longer OT for RRN as evidenced in two studies. Significantly higher direct costs and costs of the disposable instruments were also observed for RRN. The comparison between RRN and ON showed that ON is characterized by shorter OT but higher EBL, higher need of postoperative analgesics and longer HS. CONCLUSIONS: No advantage of robotics over standard laparoscopy for the treatment of clinically localized RCC was evidenced. Promising preliminary results on oncologic efficacy of RRN have been published on the T3a-b disease. Fields of wider application of robotics should be researched where indications for open surgery still persist.
