Open versus Robot-Assisted Radical Cystectomy for the Treatment of pT4a Bladder Cancer: Comparison of Perioperative Outcomes.

We compared the perioperative outcomes of open (ORC) vs. robot-assisted (RARC) radical cystectomy in the treatment of pT4a MIBC. In total, 212 patients underwent ORC (102 patients, Group A) vs. RARC (110 patients, Group B) for pT4a bladder cancer. Patients were prospectively followed and retrospectively reviewed. We assessed operative time, estimated blood loss (EBL), intraoperative and postoperative complications, length of stay, transfusion rate, and oncological outcomes. Preoperative features were comparable. The mean operative time was 232.8 vs. 189.2 min (p = 0.04), and mean EBL was 832.8 vs. 523.7 mL in Group A vs. B (p = 0.04). An intraoperative transfusion was performed in 32 (31.4%) vs. 11 (10.0%) cases during ORC vs. RARC (p = 0.03). The intraoperative complications rate was comparable. The mean length of stay was shorter after RARC (12.6 vs. 7.2 days, p = 0.02). Postoperative transfusions were performed in 36 (35.3%) vs. 13 (11.8%) cases (p = 0.03), and postoperative complications occurred in 37 (36.3%) vs. 29 (26.4%) patients in Groups A vs. B (p = 0.05). The positive surgical margin (PSM) rate was lower after RARC. No differences were recorded according to the oncological outcomes. ORC and RARC are feasible treatments for the management of pT4a bladder tumors. Minimally invasive surgery provides shorter operative time, bleeding, transfusion rate, postoperative complications, length of stay, and PSM rate.

Treatment of ureteral stones with LithoEVO device and Vapor Tunnel tool.

BACKGROUND: Vapor Tunnel (VT) technology is the result of a pulse modulation during holmium laser emission which reduces stone retropulsion. We present the outcomes of this tool in the treatment of ureteral stones. METHODS: Two hundred ten patients with a ureteral stone were randomly assigned to holmium laser lithotripsy with (group A) or without (group B) the VT technology. The 35 W LithoEVO laser generator (Quanta System, Samarate, Varese, Italy) was used. We compared operative time, dusting time, delivered energy, retreatment rate due to stone push-up, ureteral lesions, and stone-free rate (SFR) and postoperative strictures at 1 month. We also compared outcomes according to stone position. RESULTS: VT technology was associated with significantly lower mean operative time (25.7 vs. 37.2 min), dusting time (9.7 vs. 15.3 min), delivered energy (7.7 vs. 19.9 KJ). In group B 9 patients (8.5%) were retreated due to stone push-up (P=0.01) for a proximal or middle stone, 6 (5.7%) postoperative strictures occurred (P=0.03) and a higher ureteral lesion rate was observed (7.6% vs 35.2%, P=0.04). 1-month SFR was comparable (93.4% vs. 88.6%, P=0.11). Postoperative complication rate was higher in group B (P=0.05). Without VT technology, ureteral lesions and strictures rates were significantly higher independently from stone position. CONCLUSIONS: The VT technology is associated with significantly lower operative and dusting time independently from stone position, due to a reduced retropulsion, which makes treatment quicker and easier. It also avoids stone push-up especially for proximal and middle stones and reduces ureteral lesions, postoperative complications, and ureteral strictures.

Ureteral stent encrustation: evaluation of available scores as predictors of a complex surgery.

BACKGROUND: Stent encrustation is an uncommon event (13%) with a significant impact in patients' management. Aim of our study was to evaluate the available grading systems for encrusted stents. METHODS: A retrospective analysis of encrusted stents was performed in four Italian centers between 2006 and 2020. Encrusted stents were classified according to four classifications: the Forgotten Encrusted Calcificated (FECal) Score, the Kidney Ureter Bladder (KUB) Score, the Visual Grading for Ureteral Encrusted Stent Classification and the Encrustation Burden Score (EBS). Classifications were evaluated to predict complex surgery defined as: long operative time (>60 min), need of more than one surgery, and need of a percutaneous approach. The scores were compared with receiver operating characteristic (ROC) analysis as predictors of complex surgery. RESULTS: Seventy-seven patients were evaluated with a median age of 62 years (65/70). Overall FECal score >2 was present in 45/77 (58%) patients, median KUB score was 9 (6/14) and severe EBS was found in 47/77 (63%) patients. Patients were managed with cyst lithotripsy in 13/77 (17%), with ureteroscopy in 58/77 (75%) and with percutaneous nephrolithotomy (PCNL) in 6/77 (8%). Overall, 6/77 (8%) patients required a second intervention to remove the encrusted stent. All classifications predicted the need of complex surgery. On ROC analysis KUB score presented a better accuracy in predicting complex surgery compared to FECal, V-GUES and encrusted burden. CONCLUSIONS: KUB score, FECal score, V-GUES score, and encrustation burden accurately predict the need of a complex surgery. KUB showed to be superior to other classifications according to our results.

Impact of early self-clean intermittent catheterization in orthotopic ileal neobladder: prospective randomized study to evaluate functional outcomes, continence status and urinary tract infections.

BACKGROUND: Urinary diversions after radical cystectomy (RC) have a significant impact on quality of life and body image. Particularly for orthotopic neobladder (ONB), the rate of continence, urinary retention and urinary tract infections can impact on patient's quality of life. The aim of this study was to investigate whether early clean intermittent catheterization (CIC) might improve functional outcomes, continence status, and reduce the incidence of UTIs in patients with ONB. METHODS: In this prospective randomized study patients were divided in two groups. Patients were on a standard postoperative care (group A) or started CIC within the first postoperative month (group B). All patients were evaluated postoperatively at 1, 3, 6, and 9 months after ONB. The CIC was executed 4 times/daily after each voluntary micturition. The postoperative evaluation included: post-void residual volume (PVR), urine analysis and culture, number of pads/day and the self-administrated questionnaire International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). RESULTS: Thirty-nine male and 8 female patients underwent laparoscopic or robotic RC with intracorporeal ONB (37 U shaped and 10 Padua reconstructions). At the first follow up, mean PVR was in group A and B, 136.5 mL and 125.7 mL (P value: 0.105), respectively. The ICIQ-UI SF mean score was 16.2 and 17.1 (P value: 0.243) respectively and the mean no. of pads/day was 3 in both groups. 15 patients in group A and 10 in group B reported episodes of symptomatic UTIs. At 3, 6 and 9 months follow up after surgery the PVR and the ICIQ-UI SF scores were significantly improved (P value <0.0001). The number of pads decreased to 2 pads/day in group A and 1 in group B at 9 months. The episodes of UTIs significantly decreased over the time (P value <0.0001). CONCLUSIONS: Our data support the early introduction of self CIC in patients with ONB after RC. The CIC was significantly associated a reduced risk of incontinence, urinary retention, and UTI with significant improvement in QoL. These encouraging data need to be confirmed by further investigations with a larger number of patients.

Prospective Cross-Sectional Evaluation of Penile Helicine Circulation by Power Doppler During Dynamic Ultrasound in Veno-Occlusive Erectile Dysfunction.

OBJECTIVE: To evaluate the usefulness of Power Doppler to improve the diagnostic work up of veno-occlusive erectile dysfunction patients. MATERIALS AND METHODS: Patients affected by erectile dysfunction, mean IIEF 5 = 13.5 (12-17) for at least 6 months, were enrolled in a prospective cross-sectional study. All patients underwent Dynamic Power Doppler after intracavernous injection of vasoactive drugs (PGE1 20 mcg and Papaverine 6 mg). Poor responders' patients subsequently underwent to cavernosometry to get a full assessment of the vascular framework. RESULTS: 202 patients (mean age 46 years), were included in the study. 96 subjects (47.5%) who did not adequately respond to the intracavernous injection -test, subsequently underwent to cavernosometry. In 42 of 96 patients (43.7%) cavernosometry was positive for veno-occlusive dysfunction. In a total of 160 patients who did not have veno-occlusive dysfunction (54 with negative cavernosometry + 106 intracavernous injection-test responders), the Power Doppler was normal in 126 (78.8%) and pathological in 34 (21.3%) in terms of steric conformation of "low flow" vessels corresponding to the Cavernosal Terminal Unit. The diagnostic sensitivity of Power Doppler towards veno-occlusive dysfunction was found to be 52.4% (Positive Predictive Value: 39.3%), the specificity was 78.8% (Negative Predictive Value: 86.3%) and the total diagnostic accuracy was equal to 73.3%. CONCLUSION: Collected data evidenced that patients who reported altered morphological features of the Cavernosal Terminal Unit had an approximately 4-fold greater risk of having veno-occlusive dysfunction compared to patients who had normal Power Doppler features (OR = 4.076; 95% CI: 1.996-8.327).

Free-hand, transrectal ultrasound-guided hydrodissection of the retroprostatic space during robot-assisted radical prostatectomy: Impact on the learning curve.

BACKGROUND: Aim of the current study is to describe our technique of hydrodissection (HD) of the retroprostatic space (RPS) performed between the Denonvillier's fascia (DF) and prostatic capsule (PC) and to evaluate its impact on the outcomes of nerve-sparing robot-assisted radical prostatectomy (nsRALP) during the learning-curve period. METHODS: This randomized study enrolled 25 consecutive male patients with indication of nsRALP. The HD and the subsequent dissection of the seminal vesicles (SVs) and RPS was performed by a resident in learning curve for RALP; the residual portion of RALP was performed by an expert. The perioperative, oncologic and functional outcomes of 2 groups of patients (Group A: nsRALP after HD of the RPS and Group B: standard nsRALP without HD) were compared. Two analyses were performed, considering a per-protocol (PP) population regarding only randomized patients with correct HD and an Intention-To-Treat (ITT) population regarding all randomized patients. RESULTS: In 4/14 (29%) of patients of Group A the injected fluid was not intraoperatively identified in the expected plane. The groups were statistically homogeneous in relation to the baseline variables. A statistically significant difference was observed between the SVs/RPS dissection time and the SVs-related estimated blood loss in both analyses. A significantly higher rate of dry patients was observed in group A at 1 month after nsRALP. A statistically significant correlation was observed between the effective time of dissection of the SVs and the postoperative IIEF-5 drop. CONCLUSIONS: The transrectal ultrasound-guided transperineal HD seems useful for the preliminary development of the RPS during the learning curve period of nsRALP. It seems associated with less time and blood loss for the dissection of the SVs and RPS. Studies on larger cohorts are needed to draw more robust conclusions.

The Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration Project: Development of Criteria for Reporting Adverse Events During Surgical Procedures and Evaluating Their Impact on the Postoperative Course.

BACKGROUND: Intraoperative adverse events (iAEs) are surgical and anesthesiologic complications. Despite the availability of grading criteria, iAEs are infrequently reported in the surgical literature and in cases for which iAEs are reported, these events are described with significant heterogeneity. OBJECTIVE: To develop Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration criteria to standardize the assessment, reporting, and grading of iAEs. The ultimate aim is to improve our understanding of the nature and frequency of iAEs and our ability to counsel patients regarding surgical procedures. DESIGN, SETTING, AND PARTICIPANTS: The present study involved the following steps: (1) collecting criteria for assessing, reporting, and grading of iAEs via a comprehensive umbrella review; (2) collecting additional criteria via a survey of a panel of experienced surgeons (first round of a modified Delphi survey); (3) creating a comprehensive list of reporting criteria; (4) combining criteria acquired in the first two steps; and (5) establishing a consensus on clinical and quality assessment utility as determined in the second round of the Delphi survey. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Panel inter-rater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS AND LIMITATIONS: The umbrella review led to nine common criteria for assessing, grading, and reporting iAEs, and review of iAE grading systems led to two additional criteria. In the first Delphi round, 35 surgeons responded and two criteria were added. In the second Delphi round, 13 common criteria met the threshold for final guideline inclusion. All 13 criteria achieved the consensus minimum of 70%, with agreement on the usefulness of the criteria for clinical and quality improvement ranging from 74% to 100%. The mean inter-rater agreement was 89.0% for clinical improvement and 88.6% for quality improvement. CONCLUSIONS: The ICARUS Global Collaboration criteria might aid in identifying important criteria when reporting iAEs, which will support all those involved in patient care and scientific publishing. PATIENT SUMMARY: We consulted a panel of experienced surgeons to develop a set of guidelines for academic surgeons to follow when publishing surgical studies. The surgeon panel proposed a list of 13 criteria that may improve global understanding of complications during specific procedures and thus improve the ability to counsel patients on surgical risk.

Possible role of 5-alpha reductase inhibitors in non-invasive bladder urothelial neoplasm: multicenter study.

BACKGROUND: About 75% of urothelial bladder cancers are non-muscle invasive (NMIBC), and limited to mucosa (Ta or CIS) or sub-mucosa (T1). An increase of androgen expression and androgen receptors has a positive effect on oncogenic expression. We aimed to evaluate whether 5-alpha reductase inhibitors (5-ARI) have a role in NMIBC. METHODS: We retrospectively evaluated the clinical and pathological data of 423 patients with NMIBC who underwent transurethral bladder resection. We considered the number of resections, number of total recurrences, time of recurrences, and histopathology details. The population was classified into two groups: treated and untreated with 5-ARIs. The enrolled patients were in treatment with 5ARIs for symptomatic prostatic hyperplasia for at least 12 months. Mean follow-up time was 30.43 months. RESULTS: Patients treated with 5-ARIs had a lower rate of recurrence (14%) than the untreated group (37%). There was a significant difference in the mean number of recurrences between the untreated and the treated group (P=0.006). Furthermore, the treated group showed a significantly greater number of low than high grade tumors, compared to the untreated group (P≤0.05). There was a significant decrease in the number of muscle invasive tumors in treated patients (P=0.032). The recurrence-free survival rate of patients treated with 5-ARIs was significantly higher (P=0.0001). CONCLUSIONS: Long-term treatment with 5-ARIs might reduce the risk of bladder tumor recurrence, extension of lesions and increase the recurrence-free survival rate. A long-term, randomized prospective study could definitively assess the possible role of these drugs.

"VirtualBasket" ureteroscopic holmium laser lithotripsy: intraoperative and early postoperative outcomes.

BACKGROUND: The "VirtualBasket" technology (Cook Medical, Bloomington, IN, USA) is the result of pulse modulation during holmium laser emission: the laser emits part of the energy to create an initial bubble, and a second pulse is emitted when the vapor bubble is at its maximum expansion, so that it can pass through the previously created vapor channel. The aim of this study was to outline the outcomes of the "VirtualBasket" technology in ureteral and renal stones. METHODS: 160 Patients were randomly assigned to holmium laser lithotripsy with or without the "VirtualBasket" technology in ureteric or renal cases (40 per 4 groups). All procedures were performed by four experienced urologists. The Quanta System Cyber Ho 100W laser generator with 365 µm fibers was used for all the ureteral cases, whereas 272 µm fibers were used for all the cases in the renal pelvis. Demographic data, stone parameters, perioperative complications and success rates were compared. A statistical analysis was carried out to assess patients' data and outcomes. All the reported P values were obtained with the two-sided exact method at the conventional 5% significance level. The degree of stone retropulsion was graded on a Likert scale from zero (no retropulsion) to 3 (maximum retropulsion). RESULTS: All groups were comparable in terms of age, and preoperative stone size (ureter stone size: 1.2 vs. 1.1 cm; renal pelvis stone size: 1.55 vs. 1.62 cm). Compared to the regular mode, the "VirtualBasket" technology was associated with significantly lower fragmentation time (mean time for ureteral stones: 20.4 vs. 16.1 minutes, P<0.05; mean time for renal stones: 28.7 vs. 19.8 minutes, P<0.05) and total procedural time (mean time for ureteral stones 49 vs. 35.7 minutes; mean time for renal stones 67.1 vs. 52.4 minutes). There were no significant differences in terms of energy delivered to the stones, intraoperative complications and success rate at 1 month. The "VirtualBasket" technology was associated with significantly lower retropulsion. CONCLUSIONS: The "VirtualBasket" technology is associated with significantly lower fragmentation and procedural times. The reduced fragmentation time is a result of the significantly lower retropulsion of the stones during laser lithotripsy, which improves stone fragmentation efficiency.

The dramatic COVID 19 outbreak in Italy is responsible of a huge drop of urological surgical activity: a multicenter observational study.

OBJECTIVE: To describe the trend in surgical volume in urology in Italy during the coronavirus disease 2019 (COVID-19) outbreak, as a result of the abrupt reorganisation of the Italian national health system to augment care provision to symptomatic patients with COVID-19. METHODS: A total of 33 urological units with physicians affiliated to the AGILE consortium (Italian Group for Advanced Laparo-Endoscopic Surgery; www.agilegroup.it) were surveyed. Urologists were asked to report the amount of surgical elective procedures week-by-week, from the beginning of the emergency to the following month. RESULTS: The 33 hospitals involved in the study account overall for 22 945 beds and are distributed in 13/20 Italian regions. Before the outbreak, the involved urology units performed overall 1213 procedures/week, half of which were oncological. A month later, the number of surgeries had declined by 78%. Lombardy, the first region with positive COVID-19 cases, experienced a 94% reduction. The decrease in oncological and non-oncological surgical activity was 35.9% and 89%, respectively. The trend of the decline showed a delay of roughly 2 weeks for the other regions. CONCLUSION: Italy, a country with a high fatality rate from COVID-19, experienced a sudden decline in surgical activity. This decline was inversely related to the increase in COVID-19 care, with potential harm particularly in the oncological field. The Italian experience may be helpful for future surgical pre-planning in other countries not so drastically affected by the disease to date.

Holmium laser enucleation of prostate versus minimally invasive simple prostatectomy for large volume (≥120 mL) prostate glands: a prospective multicenter randomized study.

BACKGROUND: The aim of this study was to compare the perioperative and functional results between laparoscopic and robot-assisted simple prostatectomy (LSP and RASP) and Holmium laser enucleation of prostate (HoLEP) in prostate volumes ≥120 mL. The primary endpoint was to investigate and compare minimally invasive techniques in the management of large prostate gland volume, and the secondary endpoint was to evaluate the frequency and type of postoperative complications according to Clavien Dindo Classification. METHODS: This multicenter study was conducted on male patients with LUTS associated with BPO candidates for surgical treatment. The surgery approach choice in relation to the prostatic volume ≥120 mL was HoLEP or minimally-invasive simple prostatectomy (LSP or RASP). All patients were prospectively randomized into three groups, according to a simple computed randomization: HoLEP, LSP and RASP groups. During the follow-up, all patients underwent postoperative control at 1, 3, 6, 12 and 24 months from the surgical procedure. RESULTS: One hundred ten male patients were randomized in three homogeneous groups: 36 in LSP, 32 in RASP and 42 in HoLEP group. During the follow-up (mean 26.15 months), despite the significant improvement compared to baseline results, no significant differences were shown, between the groups in terms of functional and perioperative outcomes. The only statistically significant data was reported for catheterization time, that resulted longer in the LSP group than RASP and HoLEP groups (P=0.002). Furthermore, MISP resulted in longer hospitalization, and lower rate of patients with new-onset irritative symptoms. CONCLUSIONS: This prospective randomized study is the first to compare extraperitoneal LSP, RASP and HoLEP in the treatment of LUTS secondary to benign prostatic hyperplasia for prostate volumes ≥120 mL. Our findings confirm the safety and efficacy of MISP, demonstrating its equivalence in functional outcomes and perioperative morbidity in comparison to HoLEP.

Urology in the Time of Coronavirus: Reduced Access to Urgent and Emergent Urological Care during the Coronavirus Disease 2019 Outbreak in Italy.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has put a substantial burden on the Italian healthcare system, resulting in the restructuring of hospitals to care for COVID-19 patients. However, this has likely impacted access to care for patients experiencing other conditions. We aimed to quantify the impact of COVID-19 on access to care for patients with urgent/emergent urological conditions throughout Italy. MATERIALS AND METHODS: A questionnaire was sent to 33 urological units in the AGILE consortium, asking clinicians to report on the number of urgent/emergent urological patients seen and/or undergoing surgery over a 3-week period during the peak of the COVID-19 outbreak and a reference week prior to the outbreak. ANOVA and linear regression models were used to quantify these changes. RESULTS: Data from 27 urological centres in Italy showed a decrease from 956 patients/week seen just prior to the outbreak to 291 patients/week seen by the end of the study period. There was a difference in the number of patients with urgent/emergent urological disease seen within/during the different weeks (all p values < 0.05). A significant decrease in the number of patients presenting with haematuria, urinary retention, urinary tract infection, scrotal pain, renal colic, or trauma and urgent/emergent cases that required surgery was reported (all p values < 0.05). CONCLUSION: In Italy, during the COVID-19 outbreak there has been a decrease in patients seeking help for urgent/emergent urological conditions. Restructuring of hospitals and clinics is mandatory to cope with the COVID-19 pandemic; however, the healthcare system should continue to provide adequate levels of care also to patients with other conditions.

Obesity and kidney stone disease: a systematic review.

INTRODUCTION: Currently, abdominal obesity has reached an epidemic stage and obesity represents an important challenge for worldwide health authorities. Epidemiologic studies have demonstrated that the stone risk incidence increases with Body Mass Index, through multiple pathways. Metabolic syndrome and diabetes are associated with an increased renal stones disease incidence. The aim of this systematic review was to investigate the prevalence, morbidity, risk factors involved in the association between obesity and urolithiasis. EVIDENCE ACQUISITION: The search involved finding relevant studies from MEDLINE, EMBASE, Ovid, the Cochrane Central Register of Controlled Trials, CINAHL, Google Scholar, and individual urological journals between January 2001 and May 2017. The inclusion criteria were for studies written in the English language, reporting on the association between obesity and urinary stones. EVIDENCE SYNTHESIS: The underlying pathophysiology of stone formation in obese patients is thought to be related to insulin resistance, dietary factors, and a lithogenic urinary profile. Uric acid stones and calcium oxalate stones are observed frequently in these patients. Insulin resistance is thought to alter the renal acid-base metabolism, resulting in a lower urine pH, and increasing the risk of uric acid stone disease. Obesity is also associated with excess nutritional intake of lithogenic substances and with an increase in urinary tract infection incidence. Recent studies highlighted that renal stone disease increases the risk of myocardial infarction, progression of chronic kidney disease, and diabetes. Contemporary, bariatric surgery has been shown to be associated with hyperoxaluria and oxalate nephropathy. Certainly, the many health risks of obesity, including nephrolithiasis, will add more burden on urologists and nephrologists. CONCLUSIONS: Obesity related nephrolithiasis seems to necessitate weight loss as primary treatment, but the recognition of the associated complications is necessary to prevent induction of new and equally severe medical problems. The optimal approach to obesity control that minimizes stone risk needs to be determined in order to manage obesity-induced renal stones disease.

Prospective study to compare antibiosis versus the association of N-acetylcysteine, D-mannose and Morinda citrifolia fruit extract in preventing urinary tract infections in patients submitted to urodynamic investigation.

BACKGROUND: The abuse of antimicrobical drugs has increased the resistance of microorganisms to treatments, thus to make urinary tract infections (UTIs) more difficult to eradicate. Among natural substances used to prevent UTI, literature has provided preliminary data of the beneficial effects of D-mannose, N-acetylcysteine, and Morinda citrifolia fruit extract, due to their complementary mechanism of action which contributes respectively to limit bacteria adhesion to the urothelium, to destroy bacterial pathogenic biofilm, and to the anti-inflammatory and analgesic activity. The purpose of this study was to compare the administration of an association of D-mannose, N-acetylcysteine (NAC) and Morinda citrifolia extract versus antibiotic therapy in the prophylaxis of UTIs potentially associated with urological mini-invasive diagnostics procedures, in clinical model of the urodynamic investigation. METHODS: 80 patients eligible for urodynamic examination, 42 men and 38 women, have been prospectively enrolled in the study and randomised in two groups (A and B) of 40 individuals. Patients of group A followed antibiotic therapy with Prulifloxacine, by mouth 400 mg/day for 5 days, while patients of the group B followed the association of mannose and NAC therapy, two vials/day for 7 days. Ten days after the urodynamic study, the patients were submitted to urine examination and urine culture. RESULTS: The follow up assessment didn't show statistical significant difference between the two groups regarding the incidence of UTI. CONCLUSIONS: The association of mannose and NAC therapy resulted similar to the antibiotic therapy in preventing UTIs in patients submitted to urodynamic examination. This result leads to consider the possible use of these nutraceutical agents as a good alternative in the prophylaxis of the UTI afterwards urological procedures in urodynamics.

The role of detrusor overactivity in urinary incontinence after radical prostatectomy: a systematic review.

INTRODUCTION: The purpose of this review was to assess the evidence provided by literature regarding the role of detrusor overactivity (DO) in determining urinary incontinence in patients submitted to radical prostatectomy. EVIDENCE ACQUISITION: The research was based on the online PubMed database spanning the period from November 1997 to May 2016. The review was conducted in accordance with the systematic review guidelines provided by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). EVIDENCE SYNTHESIS: A total of twenty-three articles met the eligibility criteria for this systematic review. The eligible studies included a total of 812 patients with a mean number of 36 patients per study (range 29-264). The rate of patients with urodynamic DO after radical prostatectomy and reporting urge urinary incontinence ranged from 3 to 63%. The postradical prostatectomy DO was more likely to occur in patients who already had it preoperatively [OR =2.30, 95% CI: 1.39-3.82; studies 9; participants 419]. However, most representative studies accordingly indicate that intrinsic sphincter deficiency is the most common cause of postprostatectomy incontinence (PPI), considered as the sole responsible factor for such patients' incontinence (88-100% of patients evaluated); the same studies report that isolated bladder dysfunction is uncommon and that it occurs in only 3% of patients. CONCLUSIONS: The review results suggest that DO could be considered as another possible underlying mechanism for PPI. Although sphincter incompetence and weakness are the most common mechanisms related to incontinence after prostatectomy, DO may coexist or be an isolated cause of PPI. Therefore, urodynamic studies are essential to show which is and/or are the exact cause(s) of incontinence in each individual patient after RP.

Robot assisted retroperitoneal lymph-node dissection after adjuvant therapy: different indications.

BACKGROUND: Today, access to technology through robotic surgery has allowed urologists to have a valuable tool in order to perform various robot -assisted laparoscopic procedures. Robotic surgery allows reproducing complex techniques such as retroperitoneal or extended pelvic lymphadenectomy. The aim of the study was to report our series of robot assisted retroperitoneal lymphadenectomy and to demonstrate its technical and oncological feasibility. METHODS: A retrospective analysis on 7 patients (four cases of testicular tumors, one prostate adenocarcinoma, and two bladder urothelial carcinomas), who underwent retroperitoneal para-aortic, interaorto-cava and extended pelvic lymphadenectomy by robot assisted laparoscopic surgery, was conducted. We analyzed demographic, oncologic and operative data (surgical time, blood loss, and hospital stay). RESULTS: Demographic and operative data showed a mean age of 49 years (18-65), mean BMI of 26.1 kg/m2(23.7-29.1), mean operative time of198 minutes (180-220), mean estimated blood loss of 88 mL, and mean hospital stay of 3.6 days (3-5). No intraoperative complications occurred. Themean number of dissected nodes was 12 (3-20). Histopathology findings showed one case of postchemotherapy recurrenceof seminoma and six cases of fibrosis. At a mean postoperative follow-up of 39 months (7-75) no patients showed disease recurrence. CONCLUSIONS: Our case series demonstrated that the robot assisted approach isa feasible and reproducible option in skilled robotic surgical referral centers. The surgeons' experience and the optical magnification, associated to the degree of freedom offered by robotic assisted laparoscopy allow achievinga precise lymph node dissection, also in advanced oncologic patients.

Laparoscopic radical prostatectomy after previous transurethral resection of prostate using a catheter balloon inflated in prostatic urethra: Oncological and functional outcomes from a matched pair analysis.

OBJECTIVES: To explore the surgical, oncological and functional outcomes of laparoscopic radical prostatectomy in patients who have undergone transurethral resection of the prostate, using a catheter balloon inflated in the prostatic urethra. METHODS: A total of 25 patients were randomly assigned to the no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group (n = 12) and the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group (n = 13). Two matched pairs analyses were carried out to identify the 12 (control A) and 13 (control B) surgery-naïve patients. The outcomes were compared between the groups with previous transurethral resection of the prostate (no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy groups) and the controls. The rate of intra- and postoperative complications was assessed. The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and the International Index of Erectile Function 5 were used for symptoms evaluation. RESULTS: The mean blood loss was higher in patients submitted to transurethral resection of the prostate, with statistically insignificant reduced blood loss in the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group. The no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy group had longer operative time compared with both the with balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and control A groups (P < 0.05). International Index of Erectile Function 5 showed a significant difference between no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and its control group; the International Consultation on Incontinence Questionnaire showed a statistically significant difference (P < 0.05) between the no balloon previous transurethral resection of the prostate laparoscopic radical prostatectomy and control A groups. CONCLUSION: The use of a catheter balloon inflated in the prostatic urethra seems to facilitate laparoscopic radical prostatectomy in patients with previous transurethral resection of the prostate, ultimately reducing the rate of perioperative complications. These findings warrant further investigation on a larger case series with a longer follow up.

Pelvic floor muscle rehabilitation for patients with lifelong premature ejaculation: a novel therapeutic approach.

OBJECTIVES: Premature ejaculation is the most common male sexual disorder. The aim of the study was to evaluate the possible therapeutic role of pelvic floor muscle rehabilitation in patients affected by lifelong premature ejaculation. METHODS: We treated 40 men with lifelong premature ejaculation, reporting, a baseline intravaginal ejaculatory latency time (IELT) ≤ 1 min, with 12-week pelvic floor muscle rehabilitation. RESULTS: At the end of the rehabilitation, mean IELTs were calculated to evaluate the effectiveness of the therapy. At the end of the treatment, 33 (82.5%) of the 40 patients gained control of their ejaculatory reflex, with a mean IELT of 146.2 s (range: 123.6-152.4 s). A total of 13 out of 33 (39%) patients were evaluated at 6 months follow up, and they maintained a significant IELT (112.6 s) compared with their initial IELT (mean 39.8 s). CONCLUSIONS: The results obtained in our subjects treated with pelvic floor rehabilitation are promising. This therapy represents an important cost reduction compared with the standard treatment (selective serotonin reuptake inhibitors). Based on the present data, we propose pelvic floor muscle rehabilitation as a new, viable therapeutic option for the treatment of premature ejaculation.

Are early continence recovery and oncologic outcomes influenced by use of different devices in prostatic apex dissection during laparoscopic radical prostatectomy?

BACKGROUND AND PURPOSE: Treatment of patients with prostate cancer has evolved considerably in the last decade, especially in terms of minimization of the negative impacts on erectile function and continence to ensure good quality of life for treated patients. New surgical devices, such as dissectors and hemostatic scalpels, allow precise definition of the surgical field with finer dissection of the anatomic structures, with subsequent reductions in operative times and better oncologic and functional outcomes. Although monopolar scissors (MS) are still widely used, radiofrequency (RF) and ultrasound (US) scalpels have been introduced recently in laparoscopic radical prostatectomy (LRP). Despite the widespread use of these scalpels, however, few studies have compared these devices in terms of oncologic and functional outcomes after radical prostatectomy. The present study aimed to prospectively assess the impact of MS, RF, and US scalpels on margin status at apex, and recovery of urinary continence and erectile function in patients undergoing extraperitoneal LRP. PATIENTS AND METHODS: A total of 150 men were prospectively enrolled between September 2009 and April 2013 and postoperatively evaluated for continence and clinical factors. RESULTS: There were no differences in terms of operative times (P=0.9433), blood loss (P=0.9681), apical margin positivity (P=0.3965) or postoperative hospital stay (P=0.9257) among the groups. Moreover, no differences in the functional outcome scores, as evaluated by the International Consultation on Incontinence self-administered Questionnaire, at 1, 3, and 6 months postsurgery were observed. CONCLUSION: Our study represents the first evaluation of continence recovery in LRP with respect to different devices used for prostatic apex dissection. We found that the oncologic, functional, and operative outcomes were similar between these different devices during LRP, with no scalpel demonstrating superiority in continence recovery.
