Carcinoma arising in ileal conduit or orthotopic ileal neobladder reconstruction: A 20-year single institute experience.

CONTEXT: Carcinomas found in urinary diversion specimens are uncommon, particularly new primary tumours. New primary tumours primarily occur when the large intestine is utilised, whereas the occurrence is infrequent with the use of the ileum. These tumours include both the recurrence of primary malignancy or the development of a new primary malignancy originating from the small intestine. DESIGN: A search was performed within the pathology laboratory system to identify cases of malignancies involving ileal conduit/reconstruction from 2002 to 2022. Data on demographics, clinical details, pathology and management was recorded. RESULTS: A total of 13 male patients, with a mean age of 67 years (range = 49-81 years) were included in the study. The initial procedure performed included cystoprostatectomy (n = 10, including one case with right nephroureterectomy) and cystectomy (n = 3, including one case for bladder exstrophy) for initial diagnoses including urothelial carcinoma (n = 11; conventional, 6; sarcomatoid, 1; glandular 1; plasmacytoid, 1; micropapillary, 2) and adenocarcinoma (n = 1). The initial management included radical surgery with neoadjuvant chemotherapy/immunotherapy (n = 1), adjuvant chemotherapy (n = 3), intravesical adjuvant BCG (n = 2) and intravesical adjuvant chemotherapy (n = 1). Malignancies in ileal conduit or orthotopic ileal neobladder included recurrent urothelial carcinoma (n = 10) and new secondary adenocarcinomas (n = 3), which developed as early as 3 months (usually recurrence) and up to 13, 33 and 45 years (new primary malignancy) following primary resection. CONCLUSIONS: Utilising the ileum as conduit/neobladder presents a viable alternative for urinary diversion with a reduced malignancy risk compared to using a segment of the large intestine. However, there remains a potential for malignancy, either tumour recurrence or a new primary malignancy. In our study, tumour recurrence occurred up to 4 years following the initial diagnosis and the development of a new primary malignancy occurred up to 45 years after the initial diagnosis. Consequently, it is crucial to prioritise long-term follow-up for these patients undergoing this procedure.

The feasibility of robot-assisted radical cystectomy: an experimental study.

PURPOSE: To investigate the feasibility of the avatera system for performing robot-assisted radical cystectomy (RARC) followed by intracorporeal reconstruction of ileal neobladder. METHODS: Six anesthetized female pigs were used to perform RARC and formation of the intracorporeal orthotopic ileal neobladder. Three surgeons with different level of expertise in the use of robotic systems performed RARC after a short instructional lecture and a 2-h hands-on training. The urinary diversion phase was performed only by the experienced surgeon. The successful completion of the procedure, operative time for demolitive and reconstructive phases, intraoperative blood loss and malfunction of the robotic system were evaluated. RESULTS: An improvement of the operative time was observed for each surgeon. The experienced surgeon, the fellow and the resident improved their time by 11, 15, and 22 min, respectively, between the first and the second RARC performed. The most significant time difference was demonstrated by the resident, who had no previous experience in using robotic systems. The time difference between the first and the last orthotopic ileal neobladder creation for the experienced surgeon was 51 min. CONCLUSION: The feasibility of avatera system for performing complex surgical procedure such as RARC with intracorporeal neobladder formation was demonstrated by this experimental study. No major bleeding or severe malfunctions were observed during the procedures. Significant improvement in operative time was demonstrated with the increasing experience from 1st to 6th case.

Prospective evaluation of functional outcomes in 395 patients with an ileal neobladder 1 year after radical cystectomy.

PURPOSE: This study aims to report on functional outcomes in a large cohort of patients who underwent inpatient rehabilitation (IR) in a highly specialized, high-volume German urologic rehabilitation center after radical cystectomy (RC) and creation of an ileal neobladder (INB). METHODS: Data for 842 patients, who underwent three weeks of IR after RC and urinary diversion between April 2018 and December 2019 were prospectively collected. INB patients were surveyed on continence and sexual function. Data were collected at 4 weeks (T1), 6 months (T2), and 12 months (T3) after RC. Multivariate logistic regressions were performed to identify predictors of better functional outcomes. RESULTS: INB was chosen as urinary diversion in 395 patients (357 male, 38 female). Social continence (maximum of one safety pad/24 h) was reported by 78.3% of men and 64.0% of women at T3. Severe incontinence was reported by 27.3% of men and 44.0% of women. Male sex was identified as an independent predictor for the use of no pads at T3 (OR 4.110; 95% CI 1.153-14.655; p = 0.029). Nerve-sparing surgery was identified as an independent predictor both for the use of only a safety pad (OR 1.918; 95% CI 1.031-3.569; p = 0.040) and good erectile function at T3 (OR 4.377; 95% CI 1.582-12.110; p = 0.004). CONCLUSION: Urologists should aspire for nerve-sparing surgery. When advising patients before RC, functional outcomes (continence, sexual function) should be given special attention. Women should be counseled on potentially prolonged urinary incontinence.

Is Anti-Reflux Anastomosis an Advantage in an Orthotopic Ileal Neobladder? A Systematic Review and Meta-Analysis.

INTRODUCTION: We conducted a systematic review and meta-analysis to assess the available literature regarding the postoperative effects of anti-reflux anastomosis and direct anastomosis in orthotopic ileal neobladder (ONB). METHODS: We searched PubMed, Embase, and the Cochrane Library in October 2021. We included 11 studies of patients with bladder cancer who underwent radical cystectomy and ONB as urinary diversion. Outcomes evaluated in this review were ureteroenteric anastomotic stricture (UEAS), vesicoureteral reflux, renal function (RFn) impairment, and pyelonephritis. All data were analyzed using Review Manager 5.4.4 and subgroup analyses were applied. RESULTS: A total of 11 studies were eligible for meta-analysis. The synthetic data suggested that anti-reflux anastomosis and direct anastomosis were comparable in terms of RFn impairment (odds ratio (OR) = 1.69; 95% confidence interval (CI): 0.18-15.6; p = 0.65, I2 = 69%) and pyelonephritis (OR = 1.13; 95% CI: 0.65-1.99; p = 0.66, I2 = 1%) without significant difference in each group statistically. The pooled study data showed a significantly higher incidence of UEAS (OR = 2.84; 95% CI: 1.75-4.61, p < 0.0001, I2 = 50%) and a lower incidence of vesicoureteral reflux (OR = 0.24; 95% CI: 0.10-0.59; p = 0.002, I2 = 75%) in anti-reflux anastomosis compared to direct anastomosis. In subgroup analysis, anti-reflux anastomosis was more likely to result in UEAS than direct anastomosis, especially when ureteral stent was removed within 14 days. CONCLUSION: Although meta-analysis showed that overall incidence of vesicoureteral reflux was higher with direct anastomosis than anti-reflux anastomosis, the rate of vesicoureteral reflux was not directly related to impairment of RFn. The anti-reflux mechanism of ONB was positively associated with a higher incidence of significant UEAS compared to the direct approach, which can lead to kidney damage and an increased risk of secondary surgical procedures.

Delayed ileal neobladder fistula caused by bladder stones: a case report.

BACKGROUND: Ileal neobladder fistula is a rare complication after radical cystectomy, with an incidence of approximately 0.7%. At present, there are scattered reports of vesicoileal fistula, but there are no reports of ileal neobladder fistula (INF) caused by bladder stones. In this paper, a case of ileal neobladder fistula caused by chronic stimulation of bladder stones was successfully diagnosed and treated. CASE PRESENTATION: A 68-year-old man who had undergone radical cystectomy and an orthotopic ileal neobladder procedure 10 years prior presented with refractory diarrhoea and oliguria and was diagnosed with ileal neobladder fistula caused by chronic stimulation of bladder stones. We performed fistulectomy, cystotomy, partial ileectomy, and end-to-end ileal anastomosis, and the patient recovered and was discharged after the operation. CONCLUSION: Urinary calculi are delayed complications of orthotopic neobladder construction after total cystectomy. Bladder stones are a rare complication of ileal neovesical fistula, which can cause neovesical cutaneous fistula. It is difficult to diagnose through routine examination and easily misdiagnosed as acute gastroenteritis. Surgery is an effective treatment for INF and can achieve a good prognosis.

The natural course of urinalysis after urinary diversion.

OBJECTIVE: To evaluate the impact of urinary diversion on regular features of urinalysis and to screen for risk factors of infection-related complications. METHODS: We conducted a retrospective, single-centre study of 429 patients who underwent open radical cystectomy. Patients were followed for 12 months and data of the complete urinalyses were analysed at three pre-defined time points. RESULTS: Two weeks after surgery, dipstick testing with positive reactions for leukocyte esterase and haemoglobin were confirmed in 80.7% and 80% after ileal conduit (IC) and orthotopic ileal neobladder (NB), respectively. Every patient was positive for these parameters 12 months after surgery. Correspondingly, the microscopic examination detected leukocytes (84% vs. 85.4%), erythrocytes (82.8% vs. 83.8%) and bacteria (94.3% vs. 96.8%) following IC and NB reconstruction. After 12 months, all parameters were positive irrespective of the type of urinary diversion. Two weeks after surgery positive urine cultures were obtained in more than 50% of cases after IC (52.5%) and NB (60.5%) (p > 0.05). All urine cultures were positive after 12 months with significantly more poly-microbial results found after NB (81.3%) compared with IC (67.2%) (p = 0.018). In univariate and multivariate logistic regression analysis the presence of hydronephrosis was independently associated with the occurrence of infectious complications (OR 4.2; CI 95% 1.525-11.569; p = 0.006). CONCLUSION: A positive urinalysis is a common finding after urinary diversion. Hydronephrosis is a serious risk factor with respect to infection-related complications. The simple fact of a positive urinalysis does not warrant antimicrobial treatment.

Comparative analysis of the clinical effect and safety of Laparoscopic Radical Cystectomy + Orthotopic Ileal Neobladder and Open Surgery.

OBJECTIVES: To explore the clinical effect and safety of laparoscopic radical cystectomy + orthotopic ileal neobladder and open surgery. METHODS: The study was conducted at Jingzhou First People's Hospital from January 2017 to July 2018. In this study 87 patients undergoing radical cystectomy + orthotopic ileal neobladder were chosen and classified into an observation group (48 cases) and a control group (39 cases) according to the surgical methods. The observation group underwent laparoscopic surgery, while the control group underwent open surgery. Perioperative period and prognostic conditions were compared in both groups. RESULTS: The intraoperative bleeding amount obviously decreased. The recovery time of gastroenteric function and postoperative hospitalization time were significantly shortened. Postoperative pain was significantly alleviated. Compared with the control group, the observation group showed significant differences (P<0.05). The time, amount and difference in pelvic lymph node dissection in both groups were not significantly different (P>0.05). The differences in both groups in terms of the daytime/nighttime urinary continence rate, maximum urinary flow rate, internal bladder pressure, maximum bladder pressure during urination, internal urethral pressure, bladder capacity, and residual urine volume six months after the operation were not statistically significant (P>0.05). There was no significant difference in postoperative complications, including urinary fistula, bleeding, urinary tract infection, pulmonary infection, dysuria, lymphatic leakage, ureterostenosis, or relapse (P>0.05). The ileus incidence rate in the observation group was obviously lower than that in the control group, and the difference was statistically significant (P<0.05). CONCLUSION: Laparoscopic radical cystectomy + orthotopic ileal neobladder has the characteristics of limited trauma, a minimal amount of bleeding and a fast recovery. The functions of orthotopic neobladders are good, and the occurrence rate of postoperative complications is low. In addition, body immunity is protected. Hence, this procedure deserves to be promoted clinically.

Robot-assisted intracorporeal orthotopic bladder substitution after radical cystectomy: perioperative morbidity and oncological outcomes - a single-institution experience.

OBJECTIVE: To report a single-institution experience with totally intracorporeal neobladder urinary diversion (UD) after robot-assisted laparoscopic radical cystectomy (RARC). PATIENTS AND METHODS: A total of 158 patients underwent totally intracorporeal neobladder UD after RARC between 2003 and 2016. Patient demographics, intraoperative and pathological data, 30- and 90-day perioperative mortality and complications were recorded. Complications were classified according to the modified Clavien-Dindo classification. The 5-year overall (OS) and cancer-specific survival (CSS) rates were estimated by Kaplan-Meier plots. RESULTS: Most of the patients were male (84%) and had clinical T Stage ≤2 (87%). The mean operation time was 359 (SD ±98) min, with a median (range) estimated blood loss of 300 (50-2200) mL. Most of the men (86%) received a nerve-sparing procedure and 38% of the females an organ-sparing approach. A lymph node dissection was performed in 156 (99%) patients, with a median (range) yield of 23 (7-48) nodes. Conversion to open surgery occurred in five patients (3%). We recorded negative margins in 156 patients (99%). The median (range) follow-up was 34 (1-170) months, with 30- and 90-day mortality rates of 0%. Clavien-Dindo Grade III-IV complications occurred in 29 of 158 (18%) patients at 30-days and in eight of 158 (5%) between 30-90 days, resulting into a 90-day overall high-grade complication rate of 23%. The unadjusted estimated 5-years recurrence-free survival, CSS and OS rates were 70%, 72%, and 71%, respectively. CONCLUSION: In our present series the complication and oncological results were similar to open RC series, suggesting that RARC followed by totally intracorporeal neobladder UD is a safe and feasible alternative.

Health-related quality of life after radical cystectomy and ileal orthotopic neobladder: effect of detailed continence outcomes.

PURPOSE: To objectively quantify continence rates and to correlate continence outcomes with health-related quality of life (HRQOL) after radical cystectomy and orthotopic ileal neobladder (ONB). METHODS: Questionnaires were sent to 244 patients who underwent radical cystectomy with ONB between 2004 and 2015, and information about the current continence status was retrieved. To objectify postoperative urine loss, daytime and nocturnal pad tests were performed. Continence was defined as need of up to one safety pad. HRQOL was assessed using EORTC QLQ-C30 scoring with global health status being the primary endpoint. Statistical analysis included Fisher's test, Mann-Whitney U test, Pearson's rank correlation, and binary regression models (p < 0.05). RESULTS: 178 patients (73.0%) answered the QLQ-C30 questionnaires and were included in the study. Median follow-up was 61 months. Median daytime pad use was 1 and median daily urine loss based on pad testing was 4.0 g, leading to a daytime continence rate of 48.5%. Continence had a significant impact on postoperative HRQOL (p = 0.017). ICIQ-SF score (p = 0.001, OR = 0.805) and need for condom catheter during nighttime (p = 0.015, OR = 0.123) were independent predictors for worse HRQOL outcomes based on global health status. A history of pelvic floor muscle training was an independent predictor of increased HRQOL (p = 0.009, OR = 10.459). CONCLUSIONS: Need of condom urinals and higher ICIQ-SF scores are independent predictors for worse HRQOL outcomes. We show significant beneficial effects of pelvic floor muscle training on patients' HRQOL.

Florence robotic intracorporeal neobladder (FloRIN): a new reconfiguration strategy developed following the IDEAL guidelines.

OBJECTIVE: To describe our step-by-step technique for robotic intracorporeal neobladder configuration, including the stages of conception, development and exploration of this surgical innovation, according to the Idea, Development, Exploration, Assessment, Long-term follow-up (IDEAL) Collaboration guidelines. PATIENTS AND METHODS: The Florence robotic intracorporeal neobladder (FloRIN) was performed employing the following main surgical steps: isolation of 50 cm of ileum; bowel anastomosis; urethro-ileal anastomosis creating an asymmetrical 'U'-shape (30 cm distally and 20 cm proximally to anastomosis), ileum detubularisation; posterior wall reconfiguration as an 'L'; bladder neck reconstruction; anterior folding of the posterior plate to reach the 12 o'clock position; uretero-enteral 'orthotopic' bilateral anastomosis. The conception and development of the FloRIN followed the IDEAL guidelines recommended stages: Phase 1 (simulation) involved the neobladder robotic configuration using silicone models. Phase 2a (development) aimed to reproduce the configuration in an open fashion in one patient, and then in the first three robotic procedures. Phase 2b (exploration) consisted of the technique standardisation in 15 consecutive robotic approaches. Phase 2a and 2b included urodynamics and imaging assessment of the patients treated. RESULTS: From February 2016 to September 2017 FloRIN was performed in 18 patients. Comparing the first three (Phase 2a) with the subsequent 15 patients (Phase 2b), the median (interquartile range [IQR]) reconstruction operating time was 260 (220-340) vs 160 (150-210) min, respectively. Postoperative surgical complications occurred in four of the 18 patients (22.1%), including one surgical Clavien-Dindo Grade III and three Grade I, postoperative medical Clavien-Dindo Grade II complications occurred in three (16.7%) patients. On urodynamic examination (available in nine [50%] patients) the median (IQR) reservoir cystometric capacity, compliance, and post-void residual were 240 (220-267) mL, 18 (12.5-19.8) mL/cmH2 O, and 0 (0-50) mL, respectively. Ultrasonography showed no Grade ≥2 vesico-ureteric reflux. CONCLUSION: We describe the FloRIN configuration, showing its technical feasibility with acceptable time efficiency. The first cases studied had good reservoir capacity, low pressure with no reflux, and complete voiding.

The surgical technique and initial outcomes of Anatolian neobladder: a novel technique of ileal neobladder after radical cystectomy.

BACKGROUND: We describe a detailed novel step-by-step approach for creation of an ileal neobladder and compare the outcomes with standart neobladder. METHODS: Between August 2009 and January 2016, 36 consecutive patients with bladder cancer underwent radical cystectomy and orthotopic urinary diversion with an ileal neobladder. A novel technique of ileal neobladder construction, called the Anatolian neobladder, was designed by a single surgeon (ZT). Demographics and clinical data were collected. Perioperative, oncologic, and functional outcomes were reported. Complications were graded as early or late. These outcomes were compared with patients who underwent standard neobladder during this period in our center. RESULTS: The operation was technically successful in all cases. Early postoperative complications occurred in 33.3% of the patients. Daytime continence was achieved successfully in 83.3% of the patients. No patient had severe metabolic acidosis. Six patients (16.6%) died during follow-up, five due to metastatic bladder cancer and one due to a cardiac problem. There was no any statistically significant difference between novel technique and standard neobladder for oncological and functional outcomes. CONCLUSIONS: The Anatolian ileal neobladder is as feasible and safe as standard neobladder technique for urinary diversion in patients with bladder cancer undergoing radical cystectomy.

Evolution of robot-assisted orthotopic ileal neobladder formation: a step-by-step update to the University of Southern California (USC) technique.

OBJECTIVE: To describe our, step-by-step, technique for robotic intracorporeal neobladder formation. PATIENTS AND METHODS: The main surgical steps to forming the intracorporeal orthotopic ileal neobladder are: isolation of 65 cm of small bowel; small bowel anastomosis; bowel detubularisation; suture of the posterior wall of the neobladder; neobladder-urethral anastomosis and cross folding of the pouch; and uretero-enteral anastomosis. Improvements have been made to these steps to enhance time efficiency without compromising neobladder configuration. RESULTS: Our technical improvements have resulted in an improvement in operative time from 450 to 360 min. CONCLUSION: We describe an updated step-by-step technique of robot-assisted intracorporeal orthotopic ileal neobladder formation.

Presence of transient hydronephrosis immediately after surgery has a limited influence on renal function 1 year after ileal neobladder construction.

BACKGROUND: Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder construction. METHODS: Between January 2006 and June 2013, we performed radical cystectomy in 164 patients, and 101 received orthotopic ileal neobladder construction. This study included data available from 64 patients with 128 renal units who were enrolled retrospectively. The hydronephrosis grade of each renal unit scored 0-4. The patients were divided into 4 groups according to the grade of hydronephrosis: control, low, intermediate, and high. The grade of postoperative hydronephrosis was compared with renal function 1 month and 1 year after surgery. RESULTS: There were no significant differences in renal function before surgery between groups. One month after surgery, the presence of hydronephrosis was significantly associated with decreased renal function. However, 1 year after urinary diversion hydronephrosis grades were improved significantly, and renal function was comparable between groups. Postoperative hydronephrosis at 1 month had no significant influence on renal function 1 year after ileal neobladder construction. Limitations include retrospective design, short follow-up periods, and a sample composition. CONCLUSIONS: The presence of transient hydronephrosis immediately after surgery may have limited influence on renal function 1 year after ileal neobladder construction.

[Oncologic and perioperative outcomes of robot-assisted radical cystectomy: A single-center prospective series]. / Résultats oncologiques et périopératoires de la cystectomie totale robot-assistée pour cancer : une série prospective monocentrique.

INTRODUCTION: The aim of this study was to report perioperative and oncological outcomes of robot-assisted radical cystectomy (RARC) in a single-center series and to evaluate the impact of the experience on perioperative outcomes. METHODS: Between March 2012 and January 2016, 41 patients underwent RARC associated with extended pelvic lymphadenectomy for muscle-invasive bladder cancer. All RARC included were performed by a single-surgeon in one center. Perioperative and oncological datas were collected prospectively. Recurrence-free (RFS), overall (OS) and cancer-specific survivals (CSS) were estimated using the Kaplan-Meier Method. The impact of the experience on perioperative data was estimated using Spearman's correlation test. RESULTS: Mean age was 67,7years (±10.6). Most patients underwent neoadjuvant chemotherapy (73.2%). Mean operative time and mean estimated blood loss were respectively 319.5minutes (±85.3) and 662.5mL (±360.9). Eight patients needed perioperative blood transfusion (19.5%). Conversion to open surgery was necessary in 3 cases (7.3%). Ileal neobladder was performed in 26.8% of the cases (54.5% being performed intracorporeal), and non-continent urinary diversion in 73.2%. Mean nodal yield was 17.7 (±9.3). Positive surgical margins were observed in 1 patient (2.3%). Mean length of stay was 13.2 days (±9.8). Postoperative complication rate was 46,3%. After a median follow-up of 16months, estimated 2 year-OS and CSS were respectively 62 and 76.1%. Estimated 2-year RFS was 67.6%. Perioperative outcomes improved with experience with a significant decrease in operative time (P=0.04) and a significant increase of nodal yield (P=0.05). CONCLUSION: In this single-center prospective study, satisfactory perioperative and oncological outcomes after RARC were observed despite the learning curve. Perioperative outcomes improved with surgeon's experience. Further studies are needed to confirm these findings. LEVEL OF EVIDENCE: 4.

[The W-shaped ileal neobladder: Long term functional outcomes and health-related quality of life]. / La néovessie iléale en W : résultats fonctionnels et qualité de vie à long terme.

PURPOSE: To evaluate functional outcomes and patients' health-related quality of life over ten years after a W-shaped ileal neobladder urinary diversion. PATIENTS AND METHODS: From 1994 to 2004, 87 patients with bladder cancer underwent a cystoprostatectomy with a W-shaped ileal neobladder. Among them, 31 patients (35.6%) were evaluated. The average follow-up was 158months, average age was 72years. We assessed functional outcomes (use of protections, USP score, uroflowmetry, postvoid residual volume), overall health-related quality of life (SF-36 score), and specific urinary-related quality of life (Ditrovie scale). RESULTS: Daytime continence was satisfactory in 29 patients (96.8%). Night-time continence was satisfactory in 27 patients (87.1%). Mean daytime continence, hyperactivity and dysuria scores of the USP were respectively 1.5/9, 3.2/21 and 2/9. Mean value of the maximum flow rate was 18mL/s for an average voiding volume of 324mL and an average postvoid residual volume of 70mL. The 8 dimensions of the SF-36 were all comparable with the French population's values. According to the Ditrovie scale whose average value was 1.83, the health-related quality of life was unchanged or little changed by urinary disorders in 28 patients (90.3%). CONCLUSIONS: Our results suggest that voiding status and health-related quality of life remain satisfactory over ten years after an orthotopic ileal neobladder derivation. LEVEL OF EVIDENCE: 5.

Minimal invasive treatment of benign anastomotic uretero-ileal stricture in Hautmann neobladder with thermoexpandable ureteral metal stent.

Technical challenges and increased morbidity of open reconstruction for uretero-ileal strictures have led to a search for minimal invasive treatments as an alternative solution. The insertion of a thermo-expandable ureteral Memokath 051(®) metal stent across benign uretero-ileal anastomotic stricture in orthotopic neobladder has not been described in the English literature. Herein, we describe a case of a woman with a Hautmann neobladder and a 3.5 cm benign stricture of the right uretero-ileal anastomosis that was treated with insertion of a thermo-expandable ureteral Memokath 051(®) metal stent.

Bacillus Calmette-Guérin treatment of urothelial carcinoma arising in the ileal neobladder after radical cystectomy.

In January 2005, a 66-year-old man underwent radical cystectomy and ileal neobladder reconstruction for invasive bladder cancer. A total of 3 years after the cystectomy, left-side ureteral cancer was diagnosed, and a nephroureterectomy was carried out in May 2008. In October 2011, he complained of asymptomatic macroscopic hematuria. We detected multiple papillary pedunculated and broad-based tumors in the left side and the dome of the neobladder. The patient underwent transurethral resection of the bladder tumor, and a pathological diagnosis of high-grade pTa urothelial carcinoma was made. A total of 4 months later, tumors recurred in the right side and anterior wall of the neobladder. We carried out transurethral resection of the bladder tumor again; the pathological diagnosis was high-grade pTa urothelial carcinoma with carcinoma in situ. Bacillus Calmette-Guérin instillation was carried out seven times into the neobladder, without any severe side-effects. Tumor recurrence was not observed up to 8 months after bacillus Calmette-Guérin treatment.

The clinical study of urinary flow parameters after drag-and-bond anastomosis for ileal orthotopic neobladder reconstruction.

AIM: To assess the viability of this procedure in laparoscopic radical cystectomy with ileal orthotopic neobladder reconstruction, the objective of this study is to examine the relationship between urinary flow parameters of urethral drag-and-bond anastomosis in the reconstruction of the ileal orthotopic neobladder. METHODS: 36 patients with bladder cancer underwent laparoscopic radical cystectomy with ileal orthotopic neobladder reconstruction at Jiangxi provincial people's hospital between June 2016 and January 2021,16 patients underwent intermittent urethral anastomosis, while 20 patients underwent neobladder-urethral drag-and-bond anastomosis. The maximum bladder capacity, residual urine output, maximum urinary flow rate, and outlet morphology of the new bladder neck were all monitored throughout postoperative follow-up regularly. RESULTS: There was no significant difference between the urethral drag-and-bond anastomosis group (group A) and the conventional anastomosis group (group B) at 3 months and 12 months after surgery, and the maximum bladder capacity (3 months, 488.35 ± 51.56 ml vs 481.06 ± 40.61 ml, t = -0.462, P = 0.647; 12 months, 496.35 ± 51.09 ml vs 476.56 ± 56.33 ml, t = -1.103, P = 0.278), residual urine output (3 months, 44.15 ± 24.12 ml vs 38.69 ± 21.82 ml, t = -0.704, P = 0.486;12 months, 49.65 ± 26.95 ml vs 36.75 ± 21.96 ml, t = -1.546, P = 0.131) and maximum urine flow rate (3 months, 12.36 ± 2.63 ml/s vs 13.60 ± 2.82 ml/s, t = 1.361, P = 0.182;12 months, 12.18 ± 3.14 ml/s vs 11.13 ± 3.01 ml/s, t = -1.004, P = 0.322) of the two groups were not significant (P > 0.05). The new bladder outlet morphology was not distorted in group A patients, the continuity was good, and there were fewer associated complications. CONCLUSIONS: There was no significant difference in postoperative urodynamic parameters between the urethral drag-and-bond anastomosis group and the conventional anastomosis group, and the postoperative new bladder outlet was in good shape, with clinical significance.

Orthotopic detaenial sigmoid neobladder after radical cystectomy: technical considerations, complications and functional outcomes.

PURPOSE: In recent years the orthotopic neobladder has gained increasing popularity in patients who undergo radical cystectomy. However, there are only a few reports of orthotopic neobladders reconstructed from the sigmoid without detubularization. We investigated the complications and functional outcomes of the orthotopic sigmoid neobladder reconstructed using our detaenial technique. MATERIALS AND METHODS: We performed a retrospective study of the detaenial sigmoid neobladder in 210 consecutive patients who underwent radical cystectomy at our institution from January 2003 to March 2010. ANOVA was used to investigate urodynamic finding differentials with time. Univariable and multivariable analyses were done to determine factors influencing continence. RESULTS: Median followup was 48 months. Early complications (90 days or less) were observed in 65 patients (31%). Late complications (greater than 90 days) were observed in 45 patients (21.5%). Five-year daytime and nighttime complete continence rates were 74.6% and 57.1%, respectively. Younger age was the only independent factor associated with complete continence during the day (OR 2.342, 95% CI 1.803-3.041, p <0.001) and night (OR 1.193, 95% CI 1.087-1.310, p <0.001). Mean maximal capacity and post-void residual urine were 328.8 and 22.2 ml, respectively. The mean maximal flow rate was 18.5 ml per second. The mean end filling pressure, pressure at maximal capacity and maximal intravesical pressure were 35.8, 55 and 60.6 cm H2O, respectively. These parameters remained stable with time (each p >0.05). CONCLUSIONS: This study confirms that detaenial sigmoid neobladder is a safe, feasible alternative for urinary diversion.

First case of robot-assisted radical cystectomy and intracorporeal neobladder reconstruction with the Hugo RAS system: step-by-step surgical setup and technique.

Robotic assisted radical cystectomy (RARC) is a standard option for the treatment of bladder cancer. Currently, novel platforms are entering the market and the Hugo RAS (Medtronic, Minneapolis, MN, USA) is a new system consisting of an open console with 3D-HD screen and a multi-modular fashion. Even if several series are already available for radical prostatectomy, to now a full description of RARC performed with Hugo RAS is still lacking. We report the first case of RARC with intracorporeal neobladder performed with the Hugo RAS-and another case of RARC with ureterostomy. Both patients were affected by MIBC. Case 1 was a 61-year-old patient without comorbidities (CCI 4), in which a Bordeaux ileal neobladder was scheduled after previous NAC. The second was the case of a 70-year-old one with CCI 7 and BMI 35; in this case, a ureterostomy was planned. Details of the robotic system: one 11 mm endoscope port was placed on the midline 2 cm above the umbilicus. Another two 8 mm robotic ports were symmetrically placed under vision on a transversal line-located 1 cm below the umbilicus. A third robotic port was positioned on the left side in a W configuration. All ports were located at least 9 cm between each other. Finally, two assistant ports were positioned in the right abdominal site. All arm-carts were parked 45-60 cm from the operative bed, before the docking process begins. Three arm-carts were parked on the left side, the assistant and the scrub nurse worked on the right side, while the energy tower stayed at the foot of the bed, according to the previous description of Hugo RAS robotic radical prostatectomy. The endoscope arm-cart is docked first, then the adjacent left carts are docked; finally, the surgeon's right-hand cart is docked from the right side of the bed. The docking angles and tilt we applied were: endoscope: 175°; minus 45°; surgeon left hand 140°; minus 30°; surgeon right hand 225°; minus 30°; fourth arm 125°; plus 15°. The instruments we used were those fitting our conventional four-instrument setup for RARC: monopolar shears, Maryland forceps, needle driver and Cadiere as the fourth arm. The procedures were completed without technical errors or technological failures-requiring a change in surgical strategy. Docking time was approximately 35 min; console time up to urethral dissection was 150 and 140 min in Case 1 and 2. The time for pelvic nodal dissection was approximately 37 min for both. The multi-modularity fashion of the Hugo RAS allowed an easy management of the bowel in Case 1; the absence of robotic staplers required the use of the laparoscopic ones, managed by an adjunctive assistant with room within the cart. In conclusion, RARC with the Hugo RAS is a feasible procedure able to reproduce all surgical steps without critical errors or complications requiring a change in surgical planning. Urinary diversion with intracorporeal reconstruction is feasible as well, with adequate preliminary outcomes.
