RESUMEN
OBJECTIVES: To describe the contemporary evolution of day-case bladder outflow obstruction (BOO) surgery in England and to profile day-case BOO surgery practices across England in terms of the types of operation performed and their safety profiles. MATERIALS AND METHODS: This was a retrospective observational analysis of Hospital Episode Statistics and UK Office for National Statistics data. All 111 043 recorded operations across 117 hospital trusts over 66 months, from 1 January 2017 to 30 June 2022, were obtained. Operations were identified as one of: transurethral resection of prostate (TURP); laser ablation or enucleation; vapour therapy; prostatic urethral lift (PUL); or bladder neck incision. Monthly day-case rate trends were plotted across the study period. Descriptive data, day-case rates and 30-day hospital readmissions were analysed for each operation type. Multilevel regression modelling with mixed effects was performed to determine whether day-case surgery was associated with higher 30-day hospital readmissions. RESULTS: Day-case patients were younger, with fewer comorbidities. Time series analysis showed a linear day-case rate increase from 8.3% (January 2017) to 21.0% (June 2022). Day-case rates improved for 92/117 trusts in 2021/2022 compared with 2017. Three of the six trusts with the highest day-case rates performed predominantly day-case TURP, and the other three laser surgery. Nationally, PUL and vapour surgery had the highest day-case rates (80.9% and 38.1%). Most inpatient operations were TURP. Multilevel regression modelling found reduced odds of 30-day readmission after day-case BOO surgery (all operations pooled), no difference for day-case vs inpatient TURP, and reduced odds following day-case LASER operations. CONCLUSIONS: The day-case rates for BOO surgery have linearly increased. Minimally invasive surgical technologies are commonly performed as day cases, whereas high day-case rates for TURP and for laser ablation operations are seen in a minority of hospitals. Day-case pathways to treat BOO can be safely developed irrespective of operative modality.

Recurrent bladder neck sclerosis is one of the common complications of endoscopic treatment of benign prostate hyperplasia, which often leads to multiple re-operations, including complex open and laparoscopic reconstructive procedures. One of the most promising minimally invasive methods for preventing recurrence of bladder neck sclerosis is balloon dilatation under transrectal ultrasound guidance. To improve the results of using this technique, a urethral catheter with a biopolymer coating, capable of depositing a drug and eluting it under the influence of diagnostic ultrasound, was proposed.

The study aimed to investigate the clinical effect of transurethral columnar balloon dilation of the prostate combined with holmium laser in the treatment of bladder neck contracture (BNC). This retrospective study included 41 patients with BNC, who had been treated with transurethral columnar balloon dilation and holmium laser in our hospital from June 2020 to June 2022. Admission, operation, and discharge of all the patients were completed in 24 h. The patients' satisfaction, postoperative complications, and chronic pain after operation were followed up. Clinical parameters, such as International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), quality of life (QoL), and post-void residual volume (PVR) in pre-operation, 1 month and 6 months after operation were recorded. All patients underwent the operations successfully. Six patients experienced urge incontinence and one patient experienced recurrence of BNC after 12 months. At 1 month and 6 months after the operation, IPSS, QoL, PVR, and Qmax of the patients were significantly better than those before the operation (P < 0.05). Transurethral columnar balloon dilation of the prostate combined with holmium laser can effectively treat BNC with simple performance and satisfactory clinical effects. It is a minimally invasive treatment that can be conducted by simple day surgery.

OBJECTIVE: To evaluate the effect of equal temperature bladder irrigation on bladder spasm, postoperative bleeding, vital signs and discomfort of chills in patients of transurethral resection of prostate using meta-analysis. METHODS: Several electronic databases included Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, China Biology Medicine (CBM) were searched systematically for published randomized controlled trial about equal temperature bladder irrigation in patients with transurethral resection of prostate before November 20, 2019. Two reviewers selected independently the literature in the light of the inclusion and exclusion criteria, assessed the risk of bias by quality assessment and extracted data which were consisted of clinical efficacy indexes, such as incidence of bladder spasm, severity of bladder spasm, incidence of tube plugging, amount of bladder flushing fluid, time of bladder flushing, heart rate, systolic pressure, diastolic pressure, and incidence of chills. Data were pooled using fixed-effects model or random-effects model, and the summary effect measure was calculated by risk ratio (RR) or mean difference (MD) and 95% confidence interval (95%CI). Meta-analysis was performed by Review Manager 5.3 Software. RESULTS: In the study, 13 randomized controlled trails met the requirement with a total of 2 033 patients of transurethral resection of prostate were included, of whom 1 015 were carried out with equal temperature bladder irrigation and 1 018 with room temperature bladder irrigation. The results of meta-analysis showed that incidence of bladder spasm [RR=0.51, 95%CI (0.45, 0.57), P < 0.001], severity of bladder spasm [MD=-1.61, 95%CI (-2.00, -1.23), P < 0.001], incidence of urinary blockage [RR=0.29, 95%CI (0.19, 0.44), P < 0.001], dosage of bladder irrigation [MD=-6.75, 95%CI (-7.33, -6.17), P < 0.001], time of bladder rinse [MD=-7.60, 95%CI (-11.91, -3.29), P < 0.001], heart rate [MD=-13.68, 95%CI (-15.19, -12.17), P < 0.001], systolic pressure [MD=-29.26, 95%CI (-31.92, -26.59), P < 0.001], diastolic pressure [MD=-29.36, 95%CI (-31.75, -26.98), P < 0.001], incidence of chills and discomfort [MD=0.37, 95%CI (0.31, 0.44), P < 0.001] in equal temperature group of the patients with transurethral resection of prostate had significantly statistical difference compared with room temperature group. CONCLUSION: Based on current available evidence, equal temperature bladder irrigation reduced the incidence of bladder spasm and urinary blockage, relieved bladder spasm, reduced dosage and time of bladder irrigation, and hardly affected normal vital signs and increased the patient' s comfort.

INTRODUCTION: In neurologically intact children with constipation and lower urinary tract symptoms, treatment of constipation frequently results in improved or resolved lower urinary tract symptoms. The impact of treatment of constipation on bladder function in children with a neurogenic bowel and bladder is not well studied. The objective of this study was to evaluate the impact of antegrade continence enemas (ACE) via Chait tube on urodynamic study (UDS) parameters and urinary continence in patients with neurogenic bowel and bladder (NGB). We hypothesized that following ACE some patients would demonstrate improved UDS parameters and improved urinary continence. MATERIALS AND METHODS: A review of patients with NGB who underwent a cecostomy was performed. Inclusion criteria required UDS within 12 months before and after Chait tube placement and no change in clean intermittent catheterization or anticholinergic medications. UDS parameters assessed included bladder capacity, bladder compliance, and bladder stability. In addition, the frequency of antegrade continence enemas and encopresis were reviewed as was the frequency of UTIs before and after the surgery. RESULTS: 8 children met inclusion criteria, including 5 girls and 3 boys, with a mean (range) age of 8.5 years (5-13). All children were on clean intermittent catheterization and 7 were on anticholinergic medications. The patients demonstrated a significant improvement in constipation and encopresis (p < 0.05). All but 1 patient had resolution of encopresis, and 6 of 7 patients who had constipation before ACE management had a resolution of constipation. 2 patients (25%) developed urinary continence (i.e., dry between CIC), and 2 others had improvement in continence. 3, 2, and 2 patients had urodynamic improvement in bladder capacity, compliance, or stability, respectively. However, no significant improvement in urinary incontinence or UDS parameters was demonstrated for the group overall. DISCUSSION: Our data demonstrate that some children with neurogenic bowel and bladder will have improvement in continence and UDS parameters following the initiation of ACE. Despite significant improvement in constipation and encopresis, the frequency of bladder improvement in this population appears less than that reported in neurologically intact children following treatment of constipation. Confirmatory studies with a larger number of children are needed. However, since constipation appears to negatively impact bladder function in some children with neurogenic bowel and bladder, it is reasonable to try to eliminate significant constipation in these patients before increasing pharmaceutical management of their neurogenic bladder.

Introduction: The effect of prophylactic bladder neck incision (BNI) at time of holmium laser enucleation of the prostate (HoLEP) is unknown. The aim of our study was to examine HoLEP outcomes with a specific focus on rates of bladder neck contractures (BNCs), with and without utilizing prophylactic BNI. Materials and Methods: We performed a retrospective review of HoLEP patients from January 2021 until January 2022. Outcomes of patients who underwent BNI at time of HoLEP were compared with those who underwent standard HoLEP alone. Student's t-tests, chi-square tests, and logistic regressions were performed using SAS Studio. Results: In total, 421 patients underwent HoLEP. BNI was concurrently performed in 74 (17.6%) HoLEP patients. BNI patients were younger (67.5 ± 9.0 years vs 71.1 ± 8.2 years, p = 0.00007) and had smaller prostates (60.7 ± 30.3 cc vs 133.2 ± 64.5 cc, p < 0.0001). Procedure, enucleation, and morcellation times were shorter in the BNI group (all p < 0.0001). There was no statistical difference in same-day discharge rates (90.4% vs 87.7%, p = 0.5), short-term functional outcomes, emergency department (ED) visits, or readmission rates between the two groups. At 14 months mean follow-up, two BNCs occurred in patients in the control group (0.6%), and no BNCs occurred in patients who underwent BNI (0.0%, p = 0.5). Conclusions: BNI at time of HoLEP did not decrease the ability to achieve same-day discharge or increase 90-day complications, ED visits, or readmission rates. No BNCs occurred in patients who underwent prophylactic BNI (0.0%) despite a smaller gland size and lower specimen weight in this cohort. Further prospective studies are required to conclude if concurrent BNI at time of HoLEP is protective against BNC.

OBJECTIVE: To assess the role of bladder emptying on outcomes of males undergoing transurethral resection of the prostate (TURP). MATERIALS AND METHODS: This prospective study involved candidates for TURP (January 2017-2018) with a follow-up of 3 years. Preoperative and follow-up evaluation comprised: UF, simple PVR (S-PVR), PVR-Ratio (PVR-R) as the ratio of PVR to bladder volume (BV: voided volume (VV) + PVR), Bladder voiding efficiency (BE) as the ratio between VV and BV -(voided volume/total bladder capacity) × 100 - and the IPSS. Patients were stratified for S-PVR, PVR-R, and BVE. RESULTS: Patients recruited were 100 (mean ± SD age: 68.8 ± 8.7 years). No patient had severe complications, re-admission, nor needed blood transfusion. At baseline, 38% of the patients showed S-PVR ≤ 50 mL, 62% a S-PVR ≤ 100 mL, and 25% a S-PVR >150 mL. In both pre- and postoperative evaluation there were no significant differences in Qmax and IPSS score among the groups. In each group we found a significant improvement in Qmax, IPSS score, and S-PVR, PVR-R and BVE after TURP (except for PVR in group with lowest preoperative S-PVR). Analysing a preoperative S-PVR threshold >100 mL, PVR-R significantly increased, and BVE significantly decreased after TURP. Conversely, when preoperative S-PVR was >100 mL, PVR-R, and BVE relevantly but non significantly improved after surgery. CONCLUSION: Bladder emptying is only partially related to TURP outcomes and other preperative parameters. Patients with baseline S-PVR lower than 100 mL had the chance of greater recovery of bladder emptying after TURP.

OBJECTIVE: This study was to explore the risk factors for postoperative bladder neck contracture (BNC) after transurethral operation of prostate in patients with small-volume prostatic obstruction. METHODS: Clinicopathologic data at our center from February 2016 to January 2020 were retrospectively collected and analyzed. Clinicopathological characteristics between patients with and without BNC were compared. Multivariate logistic regression was used to determine the risk factors for postoperative BNC. RESULTS: There were a total of 39 patients (8.53%) with postoperative BNC. Multivariate logistic regression analysis demonstrated that preoperative bladder neck diameter (BND), intravesical prostatic protrusion (IPP), surgical methods (transurethral resection of prostate (TURP)/anatomical endoscopic enucleation of the prostate (AEEP)), and postoperative urinary tract infection (UTI) were independent risk factors for postoperative BNC in patients with small-volume prostatic obstruction (P < 0.05). The incidence of postoperative BNC in patients undergoing AEEP was significantly decreased compared with those undergoing TURP. The optimal cut-off value of preoperative IPP was 6.10 mm while the optimal cut-off value of preoperative BND was 2.52 cm. CONCLUSIONS: Larger preoperative bladder neck and higher preoperative IPP lead to decreased incidence of postoperative BNC in patients with small-volume prostatic obstruction. Active management of postoperative UTI could effectively prevent the occurrence of postoperative BNC. Compared with TURP, complete AEEP would contribute to reduce BNC in patients with small-volume prostatic obstruction.

CASE: A 75-year-old man presented with mixed obstructive and storage lower urinary tract symptoms (LUTS). He had undergone transurethral resection of the prostate (TURP) 5 years and laparoscopic inguinal hernia repair 20 years ago. He had a stone adherent to the bladder wall and an occlusive prostate. OUTCOME: He underwent a re-do TURP and stone removal. Stone removal revealed an underlying metal coil straddling the bladder wall, which had served as a nidus for stone formation. The metal ring was a ProTack staple from previous hernia surgery, which had detached and wandered into the bladder. At follow-up after 12 weeks, the patient was asymptomatic, and his urine was sterile. Therefore, he chose to be treated conservatively for the ProTack and was started on periodic follow-up and cystoscopic surveillance. Shortly after review, he developed intestinal obstruction, which resolved spontaneously and was thought to be secondary to adhesions from other tacks that had migrated into the peritoneal cavity. CONCLUSION: We have reported a case of a ProTack from a previous hernia repair migrating into the bladder and also causing intestinal obstruction. The case is very rare because of the combination of complications. Clinicians should beware of delayed complications and damage to other organs due to metallic hernia staples.

PURPOSE: To evaluate possible benefits and clinical feasibility of retrograde bladder filling method prior to intra-vesical catheter removal after transurethral prostatectomy (TURP) for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Male patients undergoing TURP for BPH from January 2019 to October 2019 were randomized in a 1:1 ratio into either retrograde filling (RF) or spontaneous voiding (SV) methods at a single institution to determine safety and efficacy of RF (NCT04309032), with surgeons blinded to allocation. Perioperative outcomes including postoperative complications were compared between two groups. Clinician/patients' satisfaction level which was evaluated with postoperative questionnaires were also compared. RESULTS: A total of 56 patients were randomized into two groups and 56 were included in final analysis (28 men in RF group, 26 in SV group). No significant differences in baseline characteristics including age, prostate volume, or perioperative uroflowmetry were observed. However, RF significantly facilitated time to void (67.0±63.2 vs. 144.0±78.7 min; p<0.001) and time to discharge (168.4±57.2 vs. 218.9±106.9 min; p=0.046). Immediate postoperative complications were comparable in both methods with no significant difference. Overall patient and medical staff satisfaction showed tolerable and similar response by either procedure. CONCLUSIONS: RF method for intra-vesical catheter removal is a safe and satisfactory method that can facilitate early voiding detection and shorten the time to discharge. Further trials are required to further validate our results.

Bladder neck contracture (BNC) is a rare, late complication of transurethral resection of the prostate (TURP). Although the endoscopic procedure is the primary treatment for BNC, the recurrence rate remains high. Y-V plasty offers excellent surgical results for those individuals with refractory and recurrent BNC. Traditional open operations usually fail to provide satisfactory exposure to the operating field and lead to greater invasiveness. Interrupted sutures lead to prolonged operative time and increased anastomotic leakage. Laparoscopic modified Y-V plasty is performed through extraperitoneal access to the pelvis, which provides adequate exposure to the surgical view and avoids intra-abdominal injury. After incising the anterior bladder wall neck in a Y-shaped fashion, anastomosis is performed using two absorbable barbed sutures. The mucosa and submucosa layer of the bladder is closed to both sides with consecutive sutures in a V-shape before suturing serosa, and tunica muscularis are sutured to reinforce. The aforementioned procedures reduce leakage from the anastomosis and decrease operative time and patient trauma. Extraperitoneal laparoscopic modified Y-V plasty offers significant advantages over the open approach in terms of post-surgical recovery and invasiveness, making it a feasible and safe surgical option for patients with refractory BNC.

Objective: To investigate the effect of comprehensive care based on appropriate Chinese medicine techniques on urinary retention and bladder function recovery after total hysterectomy in patients with cervical cancer. Methods: A total of 148 cases admitted after radical hysterectomy for cervical cancer from January 2019 to early September 2019 were used as the observation sample and were divided into control and experimental groups based on a randomized double-blind method. There were 74 cases each. The control group was given comprehensive care, and the experimental group was given comprehensive care based on appropriate Chinese medicine techniques. The intervention period was 2 weeks after surgery. The recovery rate of bladder function and the occurrence of urinary retention were compared between the two groups, and the duration of postoperative retention of urinary catheter, the amount of residual urine, and the feeling of urination were counted. Results: The experimental group had better urinary catheter retention time, time to first spontaneous voiding, time to get out of bed, and time to anal discharge than the control group; the experimental group had a higher rate of good bladder function recovery than the control group and better bladder recovery time, residual urine volume, and incidence of urinary retention than the control group; the patients in the experimental group had better UDI-6 scores. Conclusion: The implementation of comprehensive care based on appropriate Chinese medicine techniques can relieve patients' difficulty in urination and improve their quality of life.

Bladder neck contracture (BNC), one of the most challenging complications after transurethral resection of the prostate (TURP) and photoselective vaporization of the prostate (PVP), lacks effective treatment. In the present study, our experience in treating BNC using GreenLight laser vaporization with triamcinolone acetonide (TA) injections was shared. This is a retrospective cohort study that included 46 patients with BNC after TURP and PVP in our center. GreenLight laser surgeries (180 W) were carried out and TA was administrated simultaneously. TA injections were repeated every week for three times after surgeries. The perioperative and postoperative parameters were reviewed and compared. Bladder neck tissues were examined by immunohistochemical staining to explore the expressions of collagen I, matrix metalloproteinase-3 (MMP-3), and transforming growth factor-ß (TGF-ß) after treatments. The chief complaint symptoms of all patients were significantly relieved after our treatments. None of them showed BNC recurrence during the follow-up. Complications were rare and mild. Postoperative assessments including maximal urinary flow rate (P < 0.01), International Prostate Symptom Score (P < 0.01), quality of life index (P < 0.01), and post-void residual volume (P < 0.001) were significantly better than baseline values, respectively. Immunohistochemical staining showed significantly lower expressions of collagen I (P < 0.001), MMP-3 (P < 0.001), and TGF-ß (P < 0.001) after treatments. In conclusion, 180-W GreenLight laser with repeated TA injections demonstrated the safety and long-term efficacy in treating BNC, by inhibiting the expressions of fibrotic factors. Our procedure was a promising treatment for BNC after PVP and TURP.

PURPOSE: Refractory bladder neck contracture (BNC) following transurethral prostatectomy is rare and difficult to manage. Success rate of endoscopic treatment decline considerably after repeated treatments. Bladder neck reconstruction are often the last resort to treat refractory BNC failing endoscopic treatments. In general, experience is limited with this type of bladder neck reconstruction, particularly in adult patients. This study aims to determine the success rate, functional and patient-reported outcomes (PRO) of open Y-V plasty in treatment of refractory BNC after transurethral prostatectomy. The study also aims to determine the rate, and potential predictors of persistent storage symptoms after Y-V plasty. MATERIALS AND METHODS: Between January 2016 and February 2021, 18 consecutive patients with refractory BNC who underwent open Y-V plasty were included in this study. All patients presented with voiding dysfunction after two or more failed attempts of endoscopic treatments followed by a 3-month period of outpatient serial dilation program. Clinicopathological data were extracted from medical records including baseline demographics, aetiology of BNC, previous endoscopic treatment, operative time, length of stay, complications, uroflow findings, International Prostate Symptom Score (IPSS) and OAB-V8. Primary outcome was the success of open YV plasty, defined as no need for further instrumentation such as indwelling catheterization, urethral dilatation, urethrotomy, or open surgery. Simple linear regression analysis was performed to determine predictor factors for postoperative OAB-V8. Variables that showed p < 0.25 were included in the multiple linear regression analysis. RESULTS: Most common aetiology of BNC was transurethral resection of prostate gland (n = 18, 100%). Mean age at surgery age (SD) was 65.5 (7.3) years. Mean follow-up was 14.8 (7) months. Success rate was 100%. Postoperative Qmax improved significantly [pre-OP 6.7 (8.1) ml/s vs. post-OP was 14.8 (7.3) ml/s, p < 0.001]. Mean postvoid residual decreased significantly [pre-OP 223.3 (254.3) ml vs. post-OP 45.1 (71.0) ml, p < 0.01)]. Persistent storage symptoms were reported in 61% of patients. BMI and baseline IPSS score are significant predictors for the postoperative OAB V8 change (adjusted b (95% confidence interval) = 1.037 (0.2-1.9), 0.64 (0.28-0.99), respectively, R2 = 0.59). CONCLUSION: Y-V plasty reconstruction for refractory BNC represents a feasible and successful option with high success rate and favorable outcomes. While functional and patient-reported outcomes had significantly improved post-operatively, persistent storage symptoms after this procedure still exist. BMI and baseline IPSS score are significant predictors for persistent storage symptoms after bladder neck reconstruction.

OBJECTIVE: We present a one-session procedure for treating bladder diverticula combined with benign prostatic hyperplasia (BPH). MATERIAL AND METHODS: Between January 2015 and April 2019, transurethral plasmakinetic enucleation of the prostate (TUEP) followed by laparoscopic bladder diverticulectomy (LD) were performed in 12 patients at our institution, in four of them combined with bladder stone(s) and in one patient combined with diverticular tumor. Clinical data were retrospectively collected. RESULTS: The mean size of the prostate was 137.3 ± 96.3 (65.5-403.3) ml. The mean maximal diameter of the diverticulum was 8.0 ± 2.7 (3.2-12.0) cm. The mean total operation time was 214.2 ± 69.0 (120-300) min, and the mean enucleation time was 23.2 ± 6.4 (12-35) min. The mean intraoperative blood loss was 52.1 ± 14.9 (30-80) ml. The average pre- and post-operative maximum flow rate was 5.1 ± 1.4 (2.4-8.5) ml/s and 12.8 ± 2.3 (9.6-17.1) ml/s. Except for urinary infection in one patient, no other severe peri- or postoperative complications were observed. CONCLUSIONS: TUEP accompanied by LD in one session provides an effective and minimally invasive surgical treatment for bladder diverticula combined with BPH, with or without bladder stones, and permits reasonable operation time and rapid discharge.

STUDY OBJECTIVE: To determine the proportion of patients discharged with a urinary catheter after a same-day benign gynecologic minimally invasive hysterectomy (MIH) according to active vs passive voiding protocols. The secondary objectives included assessing postanesthesia care unit (PACU) duration and postoperative urinary retention (POUR) rate ≤2 weeks of discharge. DESIGN: Retrospective, observational cohort study. SETTING: Large integrated healthcare system serving approximately 40% of the Northern California population. PATIENTS: Patients aged 18 years or older undergoing same-day MIH without urogynecology procedures from 2015 to 2018 were categorized into active or passive voiding trial groups. Active voiding trials were defined as patients arriving in the PACU with a catheter, retrograde filling of the bladder with 300 mL saline then allowing for voiding ≥50% within 30 minutes. If the patients were unable to void this volume, they were discharged with a catheter to be removed within 24 hours. A passive voiding trial involved filling or not filling the bladder before PACU arrival without a catheter, then allowing for voiding or performing a straight catheterization if the patients were unable to void. INTERVENTIONS: Retrospective cohort study. MEASUREMENTS AND MAIN RESULTS: A total of 1644 (83.2%) patients underwent passive voiding trials, and 333 (16.8%) underwent active voiding trials. The proportion of patients discharged with a catheter was lower in the passive voiding group than in the active voiding group (5.4% vs 10.5%; p = .001). The passive group had a shorter mean PACU time than the active group (218 ± 86 vs 240 ± 93 minutes; p <.001). The crude POUR rates for the passive and active voiding groups were 1.8% and 3.0%, respectively (p = .16). CONCLUSION: Within an integrated healthcare system, patients who underwent passive voiding trials compared with those who underwent active voiding trials were discharged home from the PACU after a shorter duration. In addition, a larger proportion of the patients who underwent passive voiding trials were discharged home without a urinary catheter. There were no differences in the POUR rates. Our findings suggest that passive voiding trials can be safely used after a benign MIH to reduce hospital duration, optimize healthcare resources, and improve patient experience.

BACKGROUND AND AIM: Recalcitrant bladder neck contracture (BNC) is a common complication after transurethral resection of the prostate. Our aim was to show the outcomes of a modified cystoscopy-assisted laparoscopic Y-V plasty for BNC treatments. MATERIAL AND METHODS: We retrospectively evaluated a series of 27 patients who underwent a modified cystoscopy-assisted laparoscopic Y-V plasty for recalcitrant BNC from January 2017 to September 2019. Urinary flow rate, international prostate symptom score (IPSS), international index of erectile function-5 (IIEF-5) and bladder urethral examination by cystoscopy were performed preoperatively and postoperatively, respectively. RESULTS: All patients underwent the procedure successfully and no serious complication occurred. The median surgery time was 68.6 min without massive bleeding. The median follow-up time was 14.2 months and no patients had urinary incontinence. The maximum urine flow rate 3 months after surgery was significantly higher than prior to surgery (17.7 ± 2.1 ml/s vs. 8.2 ± 1.2 ml/s, p < 0.05). The IPSS was significantly decreased compared with the preoperative score (5.7 ± 2.3 vs. 19.2 ± 1.4, p < 0.05). The cystoscopy showed a wide bladder neck and the survival bladder flap in prostate urethral 3 months postoperatively in 92.6% (25/27) patients. CONCLUSIONS: The modified cystoscopy-assisted laparoscopic Y-V plasty is a feasible and effective technique for recalcitrant BNC treatment.

Bladder cancer (BC) is a common malignancy in the genitourinary system and the current theranostic approaches are unsatisfactory. Sensitivity and specificity of current diagnosis methods are not ideal and high recurrence and progression rates after initial treatment indicate the urgent need for management improvements in clinic. Nanotechnology has been proposed as an effective method to improve theranosis efficiency for both non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC). For example, gold nanoparticles (AuNPs) have been developed for simple, fast and sensitive urinary sample test for bladder cancer diagnosis. Nanoparticles targeting bladder cancers can facilitate to distinguish the normal and abnormal bladder tissues during cystoscopy and thus help with the complete removal of malignant lesions. Both intravenous and intravesical agents can be modified by nanotechnology for targeted delivery, high anti-tumor efficiency and excellent tolerability, exhibiting encouraging potential in bladder cancer treatment. Photosensitizers and biological agents can also be delivered by nanotechnology, intermediating phototherapy and targeted therapy. The management of bladder cancer remained almost unchanged for decades with unsatisfactory effect. However, it is likely to change with the fast-developed nanotechnology. Herein we summarized the current utility of nanotechnology in bladder cancer diagnosis and treatment, providing insights for the future designing and discovering novel nanoparticles for bladder cancer management.

Perioperative hypothermia causes postoperative complications. Prewarming reduces body temperature decrease in long-term surgeries. We aimed to assess the effect of different time-periods of prewarming on perioperative temperature in short-term transurethral resection under general anesthesia. Randomized, double-blind, controlled trial in patients scheduled for bladder or prostatic transurethral resection under general anesthesia. Eligible patients were randomly assigned to receive no-prewarming or prewarming during 15, 30, or 45 min using a forced-air blanket in the pre-anesthesia period. Tympanic temperature was used prior to induction of anesthesia and esophageal temperature intraoperatively. Primary outcome was the difference in core temperature among groups from the induction of general anesthesia until the end of surgery. Repeated measures multivariate analysis of covariance modeled the temperature response at each observation time according to prewarming. We examined modeled contrasts between temperature variables in subjects according to prophylaxis. We enrolled 297 patients and randomly assigned 76 patients to control group, 74 patients to 15-min group, 73 patients to 30-min group, and 74 patients to the 45-min group. Temperature in the control group before induction was 36.5 ± 0.5 °C. After prewarming, core temperature was significantly higher in 15- and 30-min groups (36.8 ± 0.5 °C, p = 0.004; 36.7 ± 0.5 °C, p = 0.041, respectively). Body temperature at the end of surgery was significantly lower in the control group (35.8 ± 0.6 °C) than in the three prewarmed groups (36.3 ± 0.6 °C in 15-min, 36.3 ± 0.5 °C in 30-min, and 36.3 ± 0.6 °C in 45-min group) (p < 0.001). Prewarming prior to short-term transurethral resection under general anesthesia reduced the body temperature drop during the perioperative period. These time-periods of prewarming also reduced the rate of postoperative complications.Study Registration Registered at ClinicalTrials.gov (Identifier: NCT03630887).

PURPOSE: Radical cystectomy (RC) for the management of muscle-invasive bladder cancer remains a morbid procedure with high rates of perioperative complications. The role of preoperative immunonutritional supplementation (pre-INS) in improving post-RC outcomes is promising and needs further validation. MATERIALS AND METHODS: We performed a retrospective review of 204 patients who underwent RC for bladder cancer at a single institution, comparing patients who received oral L-arginine-based pre-INS, and those who did not. Preoperative features, postoperative complications, and readmission data were collected. Outcomes of interest included development of high-grade (Clavien-Dindo III-V) complications, readmission within 30 days, ileus, total parenteral nutrition (TPN) requirement, postoperative infection, and length of stay (LOS). Categorical and continuous outcomes were assessed using Fisher's exact test and Welch T-test, respectively. Multivariable logistic regression (MLoR) analysis was used to identify predictive factors for our outcomes. RESULTS: Patients who received pre-INS had significantly lower odds of requiring postoperative TPN (17.3% vs 35.6%; Fisher p=0.015, OR=0.38) and developing postoperative infection (25% vs 45%; Fisher p=0.003; OR=0.41) but no significant difference in the rates of other outcomes. On MLoR, when adjusting for age, gender, body mass index, Charlson comorbidity index, undergoing neoadjuvant chemotherapy and operative features, pre-INS was a significant predictor of postoperative infection (Fisher p=0.02; OR=0.35) but not for high-grade complications, readmission, ileus, needing TPN or LOS. CONCLUSIONS: Preoperative immunonutrition with an L-arginine-based supplement is associated with significant reduction in postoperative infection, one of the most common complications of RC.
