Surgical Treatment of Eosinophilic Cystitis in Adults: A Report of Two Cases and a Literature Review.

Eosinophilic cystitis is a rare disease that presents with either urinary frequency, hematuria, suprapubic pain or urinary retention. Although benign, this entity may progress to diffuse bladder involvement with the need for surgical treatment. We report on 2 cases of advanced disease that required cystectomy with very complex lower urinary tract reconstruction, and review the literature of surgically treated cases.

Perioperative Outcomes and Early Survival in Octogenarians Who Underwent Radical Cystectomy for Bladder Cancer.

OBJECTIVE: To evaluate perioperative outcomes and early survival in a series of octogenarians who underwent radical cystectomy (RC) and urinary diversion for bladder cancer. PATIENTS AND METHODS: We retrospectively evaluated the clinical records of 44 patients aged ≥80 years who underwent open RC and urinary diversion at 2 high-volume centers between July 2013 and December 2015. Estimated blood loss (EBL), transfusion rate, and length of hospital stay (LOS) were evaluated. Ninety-day postoperative complications were stratified according to the type of urinary diversion. Univariable analysis was performed to identify predictors of overall and major complications. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS: Median age was 83 years (interquartile range [IQR] 81-85). Age-adjusted Charlson score was ≥4 in 37 (84%) patients, and American Society of Anesthesiologists score was ≥3 in 34 (77%) patients. Ileal conduit (IC) was performed in 21/44 (48%) cases, cutaneous ureterostomy (CU) in 20/44 (45%), and no urinary diversion was required for 3 (7%) dialytic patients. Median EBL was 700 mL (IQR 500-1,000) and 23 (52%) patients required blood transfusion. Median LOS was 13 days (IQR 10-18). Overall complications were recorded in 29 (66%) patients, with major complications observed in 12 (27%), with death occurring in 1. No differences in complications were observed between IC and CU. The 2-year OS estimate was 62.5%. CONCLUSIONS: Open RC in octogenarians has an acceptable rate of major complications and mortality. IC should be considered a good urinary diversion in these patients.

Urethral-fixation technique improves early urinary continence recovery in patients who undergo retropubic radical prostatectomy.

OBJECTIVES: To describe step-by-step an original urethrovesical anastomosis technique (urethral fixation) in patients undergoing retropubic radical prostatectomy (RRP), to compare their early urinary continence recovery with those in a control group receiving a standard anastomosis technique and to identify the predictors of early urinary continence recovery. PATIENTS AND METHODS: We compared 70 patients who underwent RRP with the urethral-fixation technique with a contemporary control group of 51 patients who received RRP with a standard urethrovesical anastomosis. In the urethral-fixation group, the urethrovesical anastomosis was made using eight single sutures. Specifically, to avoid retraction and/or deviations, we fixed the urethral stump laterally to the medial portion of levator ani muscle. Also, to maintain the normal position in the context of the pelvic floor, we fixed the urethral sphincter deeper to the medial dorsal raphe using a 3-0 polydioxanone suture at the 6 o'clock position before completing the incision of the urethral wall. Urinary continence recovery was evaluated at 1, 4, 8 and 12 weeks after catheter removal. Patients self-reporting no urine leak were considered continent. Uni- and multivariable analyses were used to identify predictors of urinary incontinence at the different follow-up time-points. RESULTS: The evaluated groups had comparable preoperative variables. At 1 week after catheter removal, 32 (45.7%) patients in the urethral-fixation group and 10 (19.6%) in the control group were continent (P = 0.01). At 4 weeks after catheter removal, 46 (65.7%) patients in the urethral-fixation group and 16 (31.4%) in the control group were continent (P = 0.001). At 8 weeks after catheter removal, 59 (84.3%) patients in the urethral-fixation group and 21 (41.2%) in the control group were continent (P < 0.001). Finally, at 12 weeks after catheter removal, 63 (90%) patients in the urethral-fixation group and 32 (62.7%) in the control group were continent (P = 0.001). The urethral-fixation technique was an independent predictor of urinary continence recovery at 1 week [odds ratio (OR) 4.305; P = 0.002); 4 weeks (OR 4.784; P < 0.001); 8 weeks (OR 7.678; P < 0.001) and 12 weeks (OR 5.152; P = 0.001) after catheter removal. CONCLUSIONS: The urethral-fixation technique significantly improves early urinary continence recovery in comparison with the standard technique. Moreover, our study confirmed that this surgical technique is an independent predictor of urinary continence recovery at 1, 4, 8 and 12 weeks after catheter removal.

Entero-neovesical fistula after radical cystectomy and orthotopic ileal neobladder: A report of two cases requiring surgical management.

INTRODUCTION:: Entero-neovesical fistula is a rare complication after radical cystectomy and orthotopic ileal bladder substitution. Typical presenting symptoms are faecaluria, pneumaturia, recurrent urinary tract infections and abdominal pain. Risk factors include history of pelvic radiation, chemotherapy and abdominal surgery, as well as diverticular colonic disease, inflammatory bowel disease and traumatic pelvic injury. The paucity of cases reported in the literature makes the management of this threatening complication very challenging. Conservative treatment has only anecdotally been reported. CASE DESCRIPTION:: We describe two cases of entero-neovesical fistula with different presentation, which both required an immediate surgical treatment. The former patient was admitted to the emergency room with faecaluria, complete urinary incontinence and fever 2 years after radical cystectomy, and a fistula between the Y-shaped neobladder and the bowel anastomosis was detected. He had previously undergone chemotherapy because of tumour progression. Undiversion into an ileal conduit was required. The latter patient presented with faecaluria 20 days after an uneventful radical cystectomy, and a fistula between the Vescica Ileale Padovana neobladder and the sigmoid was documented. Treatment included resection of the sigmoid with several small diverticula, temporary ileostomy and closure of the neobladder fistula. CONCLUSION:: Conservative treatment of entero-neovesical fistula can be attempted only in patients with small openings in the small bowel and no systemic symptoms. In all other cases, surgical treatment with bowel resection and either closure of the neobladder opening or undiversion should be the preferred option.

Retrosigmoid Versus Traditional Ileal Conduit for Urinary Diversion After Radical Cystectomy.

BACKGROUND: Ureteroileal anastomotic stricture (UAS) after ileal conduit diversion occurs in a non-negligible proportion of patients undergoing radical cystectomy (RC). Surgical techniques aimed at preventing this potential complication are sought. OBJECTIVE: To describe our surgical technique of retrosigmoid ileal conduit, and to assess perioperative outcomes and postoperative complications with a focus on UAS rate. DESIGN, SETTING, AND PARTICIPANTS: A prospective single-centre, single-surgeon cohort of 67 consecutive patients undergoing open RC with ileal conduit urinary diversion between July 2013 and April 2017 was analysed. A study group of 30 patients receiving retrosigmoid ileal conduit was compared with a control group of 37 patients receiving standard Wallace ileal conduit. SURGICAL PROCEDURE: Retrosigmoid versus Wallace ileal conduit diversion after open RC. MEASUREMENTS: Operative room (OR) time, estimated blood loss (EBL), transfusion rate, and 90-d postoperative complications were recorded and compared between the two groups. In particular, rate of UAS, defined as upper collecting system dilatation requiring endourological or surgical management, was assessed and compared. RESULTS AND LIMITATIONS: The two groups were comparable with regard to all demographic, clinical, and pathological variables. No differences were observed in terms of OR time (p=0.35), EBL (p=0.12), and transfusion rate (p=0.81). Ninety-day postoperative complications were observed in 11 (36.7%) patients who underwent a retrosigmoid ileal conduit and 20 (54.1%) patients who received a traditional ileal conduit (p=0.32). Major complications (grade 3-4) were observed in three (10%) cases in the former group and in 12 (32.4%) cases in the latter group (p=0.08). Mean (standard deviation) follow-up time was 10.8±4.0 mo in the study group and 27.5±9.5 mo in the control group (p<0.001). No single case of UAS was observed in the study group, whereas six (16.2%) cases of UAS occurred in the control group (p=0.02). The main limitation is a nonrandomised comparison of a relatively small cohort with short-term follow-up. CONCLUSIONS: In our study, we observed a significantly reduced rate of UAS and no increase in postoperative complications with the retrosigmoid ileal conduit diversion compared with standard Wallace ileal conduit diversion after open RC. PATIENT SUMMARY: We describe our surgical technique of retrosigmoid ileal conduit as urinary diversion after open radical cystectomy. Compared with traditional techniques, our technique for ileal conduit was found to be safe and reduce the risk of ureteric strictures.

Enhanced Recovery After Surgery Pathway in Patients Undergoing Open Radical Cystectomy Is Safe and Accelerates Bowel Function Recovery.

OBJECTIVE: To assess whether an Enhanced Recovery After Surgery pathway was associated with a faster bowel function recovery and no increase in morbidity compared with standard perioperative care in a contemporary series of patients undergoing radical cystectomy. METHODS: A prospective single-center single-surgeon cohort of 114 consecutive patients treated with open radical cystectomy between July 2013 and June 2016 was analyzed. A study group of 74 patients with Enhanced Recovery After Surgery pathway was compared with a control group of 40 patients with standard perioperative care. Primary outcome was recovery of bowel function, measured by resumption of bowel sounds, passage of flatus, and passage of stool. Secondary outcome was rate of overall and major 90-day postoperative complications. RESULTS: Bowel function recovery was significantly faster in the study group. Resumption of bowel sounds on postoperative day 1 was recorded in 43 (58%) vs 4 (10%) patients, passage of flatus within postoperative day 2 in 41 (55%) vs 11 (28%) patients, and passage of stool within postoperative day 3 in 37 (50%) vs no patients in the study vs control group, respectively (P < .01 for all). Overall and major 90-day complications were observed in 35 (47.3%) and 13 (17.6%) patients in the study group, and in 25 (62.5%) and 9 (22.5%) patients in the control group (P = .14 and 0.38, respectively). CONCLUSION: In patients undergoing open radical cystectomy, an Enhanced Recovery After Surgery pathway allowed a significantly faster bowel function recovery with no increase in 90-day postoperative complications compared with standard perioperative care.

Sliding-clip technique for renorrhaphy improves perioperative outcomes of open partial nephrectomy.

INTRODUCTION: the aim of this work is to assess whether renorrhaphy with the sliding-clip technique improves perioperative and early functional outcomes compared with traditional renorrhaphy in a contemporary series of patients undergoing open partial nephrectomy (PN). MATERIAL AND METHODS: A single-center single-surgeon cohort of 107 consecutive patients treated with open PN between July 2013 and March 2017 was analyzed. A study group of 48 patients undergoing renorrhaphy with the sliding-clip technique was compared with a control group of 59 patients receiving traditional renorrhaphy. Outcome measures were operative room (OR) time, warm ischemia time (WIT), estimated blood loss (EBL), rate of overall 90-day postoperative complications, and percentage change in estimated glomerular filtration rate (PCE) > 10% and >20% 1 month postoperatively. RESULTS: OR time (p = 0.02), WIT (p = 0.01) and EBL (p < 0.001) were significantly lower in the study versus control group. Overall 90-day postoperative complications were observed in 8 (16.7%) versus 21 (35.7%) patients in the study versus control group (p = 0.02). PCE > 10% and >20% 1 month postoperatively were observed in approximately 40% and 20% of patients, respectively, with no significant differences between groups. On multivariable analysis, a sliding-clip technique was an independent predictor of WIT >20 min and/or EBL >500 ml (OR 0.238, 95%CI 0.074-0.767; p = 0.01) and overall 90-day postoperative complications (OR 0.360, 95%CI 0.151-0.856; p = 0.02). CONCLUSIONS: In patients undergoing open PN, renorrhaphy with the sliding-clip technique was associated with better intraoperative and postoperative outcomes compared with traditional renorrhaphy. No significant differences were observed in terms of early renal function change.

Time of catheterization as an independent predictor of early urinary continence recovery after radical prostatectomy.

BACKGROUND: The purpose of the present study was to investigate the potential impact of catheter removal time on immediate and early urinary continence recovery in a series of patients who underwent radical prostatectomy (RP). METHODS: We prospectively collected and analyzed the clinical records of 197 patients who underwent open RP between January 2014 and December 2016. A single surgeon using the urethral fixation technique performed all procedures. Patients receiving surgery between Monday and Wednesday performed a cystogram on postoperative day (POD) 2. Conversely, other cases treated on a Thursday or Friday performed a cystogram on the following Monday (POD 3 or 4). The catheter removal was planned the day after the cystogram if there was a watertight anastomosis or with a little extravasation (<5%). Urinary continence recovery was evaluated 1 week, 1, 2 and 3 months after catheter removal. Patients self-reporting no urine leak were considered continent. Logistic regression analysis was used to identify independent predictors of urinary continence recovery at different follow-up durations. RESULTS: The median catheterization time was 3 (IQR: 3-4.2) days and acute urinary retention (AUR) was observed in 13 (6.5%) cases. At median follow-up of 12 (IQR: 9-12) months, no case of bladder neck contracture was observed. Urinary continence probabilities were 43%, 63%, 87%, 91% and 95% after 1 week, 1, 3, 6, and 12 months, respectively. On multivariable analyses, time of catheter removal was an independent predictor of urinary continence recovery after 1 week (OR 1.2; P=0.02); 1 month (OR 1.2; P=0.01); 3 months (OR 1.1; P=0.04) and 6 months (OR 1.1; P=0.03) after catheter removal. CONCLUSIONS: Time of catheterization should be considered as a postoperative parameter able to influence the immediate and early urinary continence recovery in patients undergoing RP. The impact of new surgical techniques on urinary continence recovery should be tested also considering such potential confounding factor.

Will Multi-Parametric Magnetic Resonance Imaging be the Future Tool to Detect Clinically Significant Prostate Cancer?

Multi-parametric magnetic resonance imaging is an emerging imaging modality for diagnosis, staging, characterization, and treatment planning of prostate cancer. In this report, we reviewed the literature for studies assessing the accuracy of multi-parametric magnetic resonance imaging in detecting clinically significant prostate cancer, and we critically examined the future role of this imaging tool in various clinical diagnostic settings. There is accumulating evidence suggesting a high accuracy of multi-parametric magnetic resonance imaging in ruling out clinically significant disease. Although definition for clinically significant disease widely varies, the negative predictive value is very high at up to 98%. Multi-parametric magnetic resonance imaging should, thus, be further evaluated for application in different clinical scenarios in which it is desirable to reduce the proportion of unnecessary prostate biopsies and to limit the detection of indolent disease, such as opportunistic screening, persistent prostate cancer suspicion in men with previous negative prostate biopsies, and eligibility for active surveillance. Continued improvement in standardization of technical parameters, functional sequences, and image reporting systems is a pre-requisite for a rapid and successful dissemination of this imaging modality.

Multimodal treatment for high-risk prostate cancer with high-dose intensity-modulated radiation therapy preceded or not by radical prostatectomy, concurrent intensified-dose docetaxel and long-term androgen deprivation therapy: results of a prospective phase II trial.

BACKGROUND: The optimal management of high-risk prostate cancer remains uncertain. In this study we assessed the safety and efficacy of a novel multimodal treatment paradigm for high-risk prostate cancer. METHODS: This was a prospective phase II trial including 35 patients with newly diagnosed high-risk localized or locally advanced prostate cancer treated with high-dose intensity-modulated radiation therapy preceded or not by radical prostatectomy, concurrent intensified-dose docetaxel-based chemotherapy and long-term androgen deprivation therapy. Primary endpoint was acute and late toxicity evaluated with the Common Terminology Criteria for Adverse Events version 3.0. Secondary endpoint was biochemical and clinical recurrence-free survival explored with the Kaplan-Meier method. RESULTS: Acute gastro-intestinal and genito-urinary toxicity was grade 2 in 23% and 20% of patients, and grade 3 in 9% and 3% of patients, respectively. Acute blood/bone marrow toxicity was grade 2 in 20% of patients. No acute grade ≥ 4 toxicity was observed. Late gastro-intestinal and genito-urinary toxicity was grade 2 in 9% of patients each. No late grade ≥ 3 toxicity was observed. Median follow-up was 63 months (interquartile range 31-79). Actuarial 5-year biochemical and clinical recurrence-free survival rate was 55% (95% confidence interval, 35-75%) and 70% (95% confidence interval, 52-88%), respectively. CONCLUSIONS: In our phase II trial testing a novel multimodal treatment paradigm for high-risk prostate cancer, toxicity was acceptably low and mid-term oncological outcome was good. This treatment paradigm, thus, may warrant further evaluation in phase III randomized trials.
