Enteric duplication cysts in paediatric population along with literature review / Quistes de duplicación entérica en población pediátrica y revisión de la literatura

The clinical presentation of enteric duplication cysts is dependent on the location of the cyst with symptoms varying from nausea and vomiting to abdominal distension, pain and perforation. Four patients were identified who were diagnosed with enteric duplication cysts within the period from 2019 to 2023. Three of the patients presented with signs of intestinal obstruction-abdominal distension and pain, while one had an antenatally detected abdominal mass. There were three boys and one girl with ages ranging from 4 months to 14 years. Three cases of ileal and one case of caecal duplication cyst were reported. Most of the cases showed ileal/caecal mucosa while one case demonstrated ectopic gastric mucosa. The treatment of these cysts includes surgical excision. Although radiological investigations help in arriving at a provisional diagnosis, the final diagnosis can be confirmed only after histopathological examination. Early treatment prevents complications and results in a good prognosis for the patient. (AU)

La presentación clínica de los quistes de duplicación entérica depende de la ubicación del quiste, y los síntomas varían desde náuseas y vómitos hasta distensión abdominal, dolor y perforación. Se identificaron cuatro pacientes que fueron diagnosticados con quistes de duplicación entérica en el período de 2019 a 2023. Tres de los pacientes presentaron signos de obstrucción intestinal (distensión abdominal y dolor), mientras que uno tenía una masa abdominal detectada prenatalmente. Eran tres niños y una niña con edades comprendidas entre 4 meses y 14 años. Se notificaron tres casos de quiste de duplicación ileal y un caso de quiste de duplicación cecal. La mayoría de los casos mostraron mucosa ileal/cecal, mientras que un caso mostró mucosa gástrica ectópica. El tratamiento de estos quistes incluye la escisión quirúrgica. Aunque las investigaciones radiológicas ayudan a llegar a un diagnóstico provisional, el diagnóstico final solo puede confirmarse después del examen histopatológico. El tratamiento precoz previene complicaciones y redunda en un buen pronóstico para el paciente. (AU)

Prophylactic Use of Biologic Mesh in Ileal Conduit (PUBMIC): A Randomized Clinical Trial.

PURPOSE: We assessed the effect of prophylactic biologic mesh on parastomal hernia (PSH) development in patients undergoing cystectomy and ileal conduit (IC). MATERIALS AND METHODS: This phase 3, randomized, controlled trial (NCT02439060) included 146 patients who underwent cystectomy and IC at the University of Southern California between 2015 and 2021. Follow-ups were physical exam and CT every 4 to 6 months up to 2 years. Patients were randomized 1:1 to receive FlexHD prophylactic biological mesh using sublay intraperitoneal technique vs standard IC. The primary end point was time to radiological PSH, and secondary outcomes included clinical PSH with/without surgical intervention and mesh-related complications. RESULTS: The 2 arms were similar in terms of baseline clinical features. All surgeries and mesh placements were performed without any intraoperative complications. Median operative time was 31 minutes longer in patients who received mesh, yet with no statistically significant difference (363 vs 332 minutes, P = .16). With a median follow-up of 24 months, radiological and clinical PSHs were detected in 37 (18 mesh recipients vs 19 controls) and 16 (8 subjects in both arms) patients, with a median time to radiological and clinical PSH of 8.3 and 15.5 months, respectively. No definite mesh-related adverse events were reported. Five patients (3 in the mesh and 2 in the control arm) required surgical PSH repair. Radiological PSH-free survival rates in the mesh and control groups were 74% vs 75% at 1 year and 69% vs 62% at 2 years. CONCLUSIONS: Implementation of biologic mesh at the time of IC construction is safe without significant protective effects within 2 years following surgery.

Migration of double-J ureteral stent in patients with ureteroileal anastomosis stricture undergoing radical cystectomy and orthotopic neobladder: Analysis risk factors of stent migration.

The objective was to evaluate the incidence and degree of double-J ureteral stent (DJUS) migration. Additionally, we aimed to investigate the risk factors associated with stent migration in the orthotopic neobladder group. In this retrospective study, 61 consecutive patients were included; 35 patients (45 DJUS placements) underwent radical cystectomy with orthotopic neobladder and 26 patients (35 DJUS placements) underwent urinary bladder without cystectomy between July 2021 and March 2023. All the patients were treated with a DJUS for ureteric strictures. The technical success rate was 100% in each group. The DJUS migration was significantly higher in the orthotopic neobladder group, with 22 of 45 cases (48.9%), compared to the urinary bladder group, which had 4 of 35 cases (11.4%) (P ≤ .001). Among the patients in the orthotopic neobladder group who experienced DJUS migration, stent dysfunction occurred in 18 cases (81.8%), which was statistically significant (P = .003). Multivariate logistic regression analysis revealed that only the size of the DJUS was significantly and positively associated with migration (odds ratio:10.214, P = .010). DJUS migration can easily occur in patients undergoing radical cystectomy and orthotopic neobladder, and smaller stent sizes are associated with a higher incidence of migration.

Robot-assisted intracorporeal ileal conduit urinary diversion: A two-center comparative study of Bricker versus Wallace ureteroileal anastomosis.

INTRODUCTION: This study was performed to evaluate the differences in the perioperative results, renal function, and incidence of hydronephrosis over time between the use of Bricker anastomosis and Wallace anastomosis for robot-assisted intracorporeal ileal conduit urinary diversion (RICIC). METHODS: Fifty-five patients who underwent RICIC at two institutions were evaluated (Bricker, n = 23; Wallace, n = 32). We investigated changes in estimated glomerular filtration rate and hydronephrosis before surgery and at 3, 6, and 12 months after surgery. RESULTS: The patients in the Bricker group were significantly older than those in the Wallace group. The urinary diversion time was significantly longer in the Bricker group. No significant difference in postoperative renal function was observed. Additionally, no significant difference was observed in the incidence of postoperative hydronephrosis. However, the incidence of right hydronephrosis tended to be high overall, especially in the Wallace group. No patients in either group required repair surgery or ureteral stent placement. CONCLUSIONS: In patients undergoing RICIC, there was no difference in postoperative renal function or the incidence of hydronephrosis between Wallace and Bricker anastomosis. Symptomatic hydronephrosis was not observed in either group. The present study showed that each method was equally effective and safe.

Peri- and post-operative outcomes of robot-assisted radical cystectomy after the implementation of the EAU guidelines recommendations for collecting and reporting complications at a high-volume referral center.

PURPOSE: No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. MATERIALS AND METHODS: 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1 year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. RESULTS: Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10 days from surgery, and 51% of severe complications (106/207) occurred within 35 days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3 months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4 days), the latest complications were urinary tract infection (mTTC: 40 days) and hydronephrosis/ureteral obstruction (mTTC: 70 days). CONCLUSIONS: The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

Challenges and technical aspects in the management of muscle invasive bladder cancer as retrograde radical cystectomy with ileal conduit.

Objective: To evaluate long-term outcomes in patients homogenously treated with radical cystectomy and ileal conduit for muscle invasive bladder cancer. METHODS: The retrospective study was conducted at the Urology Department of Pakistan Kidney and Liver Institute and Research Centre, Lahore, Pakistan, and comprised data from December 25, 2017, to January 16, 2023, related to patients who underwent radical cystectomy with ileal conduit with or without neo-adjuvant and adjuvant radiation, chemotherapy, or immunotherapy for papillary urothelial carcinom of the bladder. Clinical trajectory, histopathological characteristics and long-term clinical outcomes were noted. Data was analysed using SPSS 20. RESULTS: In our study of 40 patients with muscle invasive bladder cancer, males predominated (32, 80%), with a median age of 57.4 years (IQR: 29-80). Diagnosis was early in 5 (12.5%) patients with varying haematuria durations, while 34 (85%) patients had a smoking history. Comorbidities included hypertension in 17 (42.5%) patients, diabetes in 1 (2.5%) patient, both hypertension and diabetes in 9 (22.5%) patients and a combination of hypertension, diabetes, and ischaemic heart disease in 3 (7.5%) patients. Transurethral resection was performed once in 13 (32.5%) patients and multiple times in 27 (67.5%) patients. Additionally, 5 (12.5%) patients received immunotherapy, 11 (27.5%) patients underwent non-adjuvant radiation, and 14 (35%) patients received non-adjuvant chemotherapy. Papillary urothelial carcinoma was the predominant histological subtype among 37 (92.5%) patients. Patients receiving chemotherapy had significantly better overall survival (p=0.02). No significant differences were noted in recurrence or survival by therapy modality (p>0.05). These findings highlight the significance of early diagnosis, tailored treatments, and comorbidity management in muscle invasive bladder cancer patients. Age stratification revealed significant survival differences across groups (χ²=10.923, df=3, p= 0.012). Analysis by complications did not show age-related survival variations (χ² =3.978, df = 3, p=0.264). Conclusion: Achieving excellent long-term survival in MIBC patients requires a multidisciplinary approach, emphasizing early diagnosis, tailored treatment, and adherence to guidelines and protocols.

Multicenter evaluation of complex urinary diversion for renal transplantation: outcomes of complex surgical solutions.

PURPOSE: An abnormal lower urinary tract poses significant challenges for transplant surgeons. Besides the ureteral anastomosis to an ileal conduit, there are diverse complex reconstructive solutions. Due to its rarity, standardization and teaching of complex urinary diversion is extremely difficult. METHODS: The indications and outcomes of complex urinary diversions after kidney transplantation (KT) were retrospectively investigated at eight urologic transplant centers including a current follow-up. RESULTS: Of 37 patients with 21 (56%) males, vesicoureteral reflux (24%), spina bifida (22%), and glomerulonephritis (12%) were the most common causes of terminal renal failure. In 30 (81%) patients, urinary diversion was performed before KT, at a median of 107.5 (range, 10; 545) months before. Transplantations were held at a median patient age of 43 (10; 68) years, including six (16%) living donations. Urinary diversion was modified during 12 (32%) transplantations. After KT, the ileal conduit was the most common incontinent urinary diversion in 25 (67%) patients; a Mainz pouch I and bladder augmentation were the most frequent continent diversions (each n = 3). At a median follow-up of 120 months (range 0; 444), 12 (32%) patients had a graft failure with a 5-year graft survival of 79% (95%CI 61; 90). The median overall survival was 227 months (168; 286) and the 5-year overall survival 89% (69.3; 96.4). CONCLUSION: The mid-term kidney transplant function with complex urinary diversion appears to be comparable to transplants with regular urinary diversions. Hence, complex urinary diversion should always be considered as a surgical option, even during transplantation, if necessary.

Parastomal Hernia Following Ileal Conduit: Incidence, Risk Factors, and Health-Related Quality of Life.

PURPOSE: The purpose of this study was to measure the incidence of parastomal hernia (PH) after radical cystectomy and ileal conduit. Secondary aims were the identification of risk factors for PH and to compare the health-related quality of life (QOL) between patients with and without PH. DESIGN: Retrospective review of medical records combined with cross-sectional administration of the QOL instrument and telephone follow-up. SUBJECTS AND SETTING: The study sample comprised 219 patients who underwent radical cystectomy and ileal conduit for urothelial cancer between February 2014 and December 2018. The study setting was Peking University First Hospital (Beijing, China). METHODS: Demographic and pertinent clinical data, including development of PH, were gathered via the retrospective review of medical records. Participants were also asked to complete the traditional Chinese language version of the City of Hope Quality of Life-Ostomy Questionnaire (C-COH). Multiple linear regression analysis was used to identify the effect of PH on C-COH scores. Logistic regression analysis was used to identify risk factors for PH development. RESULTS: At a median follow-up of 34 months (IQR = 21-48), 43 of 219 (19.63%) patients had developed a PH. A body mass index (BMI) indicating overweight (OR = 3.548; 95% CI, 1.562-8.061; P = .002), a prior history of hernia (OR = 5.147; 95% CI, 1.195-22.159; P = .028), and chronic high abdominal pressure postdischarge (CHAP-pd) (OR = 3.197; 95% CI, 1.445-7.075; P = .004) were predictors of PH after operation. There was no significant difference between C-COH scores of patients with or without PH. No significant differences were found when participants with PH were compared to those without PH on 4 factors of the C-COH: physical scores (ß= .347, P = .110), psychological scores (ß= .316, P = .070), spiritual scores (ß=-.125, P = .714), and social scores (ß= .054, P = .833). CONCLUSION: Parastomal hernia is prevalent in patients undergoing radical cystectomy and ileal conduit urinary diversion. Overweight, hernia history, and CHAP-pd were predictors of PH development. No significant differences in QOL were found when patients with PH were compared to those without PH.

Nomogram for predicting postoperative ileus after radical cystectomy and urinary diversion: a retrospective single-center study.

OBJECTIVE: To predict the incidence of postoperative ileus in bladder cancer patients after radical cystectomy. METHODS: We retrospectively analyzed the perioperative data of 452 bladder cancer patients who underwent radical cystectomy with urinary diversion at the Second Hospital of Tianjin Medical University between 2016 and 2021. Univariate and multivariate logistic regression were used to identify the risk factors for postoperative ileus. Finally, a nomogram model was established and verified based on the independent risk factors. RESULTS: Our study revealed that 96 patients (21.2%) developed postoperative ileus. Using multivariate logistic regression analysis, we found that the independent risk factors for postoperative ileus after radical cystectomy included age > 65.0 years, high or low body mass index, constipation, hypoalbuminemia, and operative time. We established a nomogram prediction model based on these independent risk factors. Validation by calibration curves, concordance index, and decision curve analysis showed a strong correlation between predicted and actual probabilities of occurrence. CONCLUSION: Our nomogram prediction model provides surgeons with a simple tool to predict the incidence of postoperative ileus in bladder cancer patients undergoing radical cystectomy.

The impact of perioperative risk factors on long-term survival after radical cystectomy: a prospective, high-volume cohort study.

INTRODUCTION: Radical cystectomy (RC) is the gold standard for muscle-invasive bladder cancer. Nevertheless, RC is associated with substantial perioperative morbidity and mortality. We aimed to evaluate the role of important perioperative risk factors in predicting long-term survival after RC. METHODS: An analysis of the prospective cohort of patients undergoing open RC from 2004 to 2023 at our center was performed. Patients who died within one month after RC were excluded from the study. A univariate and multivariable Cox regression analysis was performed to assess the role of sex, age, urinary diversion, preoperative values of creatinine and hemoglobin, first-day postoperative values of CRP, leucocytes, and thrombocytes, perioperative Clavien-Dindo complications, perioperative chemotherapy, admission to the intensive or intermediate care unit, as well as type of histology, pathologic T-stage, positive lymph nodes, and positive surgical margins on predicting the long-term overall survival after RC. For all analyses hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs) were estimated. RESULTS: A total of 1,750 patients with a median age of 70 years (IQR: 62-76) were included. Of them, 1,069 (61%) received ileal conduit and 650 (37%) neobladder. Overall, 1,016 (58%) perioperative complications occurred. At a median follow-up of 31 months (IQR: 12-71), 884 (51%) deaths were recorded. In the multivariable Cox regression analysis, increasing age (HR: 1.03, 95%CI: 1.02-1.04, p < 0.001), higher preoperative creatinine values (HR: 1.27, 95%CI: 1.12-1.44, p < 0.001), lower preoperative hemoglobin values (HR: 0.93, 95%CI: 0.89-0.97, p = 0.002), higher postoperative thrombocyte values (HR: 1.01, 95%CI: 1.01-1.02, p = 0.02), Clavien-Dindo 1-2 complications (HR: 1.26, 95%CI: 1.03-1.53, p = 0.02), Clavien-Dindo 3-4 complications (HR: 1.55, 95%CI: 1.22-1.96, p < 0.001), locally advanced bladder cancer (HR: 1.29, 95%CI: 1.06-1.55, p = 0.009), positive lymph nodes (HR: 1.74, 95%CI: 1.45-2.11, p < 0.001), and positive surgical margins (HR: 1.61, 95%CI: 1.29-2.01, p < 0.001) negatively affected long-term survival. CONCLUSION: Beside increased age and worse oncological status, impaired renal function, lower preoperative hemoglobin values, higher postoperative thrombocyte values, and perioperative complications are independent risk factors for mortality in the long term in patients undergoing open RC.

Postoperative Outcomes and Analgesic Requirements of Single-Port vs Multiport Robotic-Assisted Radical Cystectomy.

Objective: To compare outcomes in patients undergoing robotic-assisted radical cystectomy (RARC) with urinary diversion for bladder cancer with either the single-port (SP) or multiport (MP) robotic platform. Methods: All patients who underwent SP and MP RARC at our institution between January 2018 and January 2023 were retrospectively reviewed. Postoperative analgesia was administered by a departmentwide narcotic stewardship protocol, and inpatient and outpatient narcotic use was tracked. The available preoperative clinical, operative, and postoperative outcomes were analyzed using t-test, chi-square, and Fischer exact statistical measures. Kaplan-Meier analysis with log-rank testing was used to determine the freedom from high-grade (Clavien-Dindo grade ≥3) postoperative complications stratified by SP or MP robotic use. Results: Overall, 96 patients underwent RARC with urinary diversion at our institution, with 49 MP and 47 SP procedures performed. Preoperative clinical parameters including age, body mass index, prior abdominal surgery, and use of neoadjuvant chemotherapy were similar between the two groups. Patients undergoing SP RARC had a shorter operative time (386.0 ± 90.9 minutes vs 453.6 ± 94.8 minutes, p < 0.01) and faster return of bowel function (3.4 ± 1.4 days vs 4.5 ± 2.2 days, p < 0.01). However, both cohorts had similar length of hospitalization, postoperative narcotic use, pathologic staging, and rate of positive surgical margin. Within 3 months postoperatively, both cohorts had a similar high-grade complication, hospital readmission, and cancer recurrence rate. Conclusions: The SP robot allows a safe alternative surgical approach for RARC and offers similar postoperative outcomes compared to the MP robot.

Robotic simple cystectomy as a last resort for antibiotic-recalcitrant recurrent urinary tract infections in women.

OBJECTIVE: To report a series of women with antibiotic-recalcitrant recurrent urinary tract infections (rUTI) managed with robotic simple cystectomy and ileal conduit urinary diversion. METHODS: Following Institutional Review Board approval, all female patients who underwent robotic cystectomy for rUTI between 2011 and 2021 were identified from a prospectively-maintained internal database at a tertiary care center. Exclusion criteria included interstitial cystitis, neurogenic bladder, urinary tract neoplasm, or congenital abnormality. Electronic medical records were reviewed by an independent researcher. Patients were also administered the Quality of Life Questionnaire-C30. RESULTS: Twenty-four patients met inclusion criteria. Median age was 75 years (range 53-87). Median rUTI duration was 6 (interquartile range [IQR] 2-10) years. Median urinary tract infections count in the 12-month preceding cystectomy was 5 (IQR 3-9). Infections with multidrug resistant organisms were found in 21 patients (88%). The 30-day postoperative complication rate was 79% (19/24), of which 11% were Clavien-Dindo grade ≥III. The main late complication was parastomal hernia, with 17% requiring repair or revision. At a median of 36 months (range 12-61) post-operatively, the median Quality of Life Questionnaire-C30 global health status score was 50 (range 33-83). CONCLUSION: Cystectomy is a last-resort management option for women with severely symptomatic end-stage bladders in the setting of antibiotic-recalcitrant rUTI. Patients should be counseled thoroughly regarding possible acute and long-term postoperative complications. Select patients, managed in high-volume referral centers, can benefit from robotic simple cystectomy with ileal conduit urinary diversion.

Robot-assisted Radical Cystectomy with Totally Intracorporeal Urinary Diversion Versus Open Radical Cystectomy: 3-Year Outcomes from a Randomised Controlled Trial.

BACKGROUND AND OBJECTIVE: Randomised controlled trials (RCTs) comparing open radical cystectomy (ORC) and robot-assisted RC (RARC) have involved an extracorporeal approach for urinary diversion (UD), undermining the potential benefits of a totally robotic procedure. Our objective was to compare 3-yr outcomes from a RCT comparing ORC to RARC with totally intracorporeal UD (iUD). METHODS: Patients with cT2-4 N0 M0 or bacillus Calmette-Guérin-failed high-grade non-muscle-invasive urothelial carcinoma who were candidates for RC without absolute contraindications to robotic surgery were included. A covariate adaptive randomisation process based on body mass index, American Society of Anesthesiologists score, preoperative haemoglobin, type of UD, neoadjuvant chemotherapy, and cT stage was used. The primary endpoint was to investigate the superiority of RARC with iUD in terms of a 50% reduction in transfusion rate. Secondary outcomes included adherence to an early recovery after surgery protocol, perioperative and postoperative outcomes, readmission and complication rates, a cost analysis, and functional, oncological, and health-related quality-of-life outcomes. KEY FINDINGS AND LIMITATIONS: Overall, 116 patients were enrolled. The primary endpoint was confirmed, as the overall perioperative transfusion rate was significantly lower in the RARC cohort, with an absolute risk reduction of 19% (95% confidence interval 2-36%; p = 0.046). No differences in perioperative and postoperative complications and 3-yr oncological outcomes were observed between the groups. Despite the superiority of ORC on quantitative analysis of night-time pad use, there were no differences in the probabilities of recovery of daytime and night-time continence. Body image was significantly better in the RARC cohort. Cost analysis confirmed that RARC is a more expensive surgical procedure. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our findings support RARC with iUD as a safe surgical option; the transfusion rate was reduced by 50% and the complication rates and 3-yr oncological outcomes were comparable to those with ORC. The minimally invasive nature of RARC was reflected in better body image perception in this cohort. The probabilities of daytime and night-time continence recovery were comparable between the groups. Higher costs remain a drawback of robotic surgery. PATIENT SUMMARY: This RCT demonstrated a 50% transfusions rate's reduction compared to ORC. We confirmed safety and feasibility of RARC with i-UD providing comparable peri- and postoperative complication rates, as well as, 3yr oncologic outcomes to those of ORC. Patients receiving either RARC-iUD or ORC had comparable probabilities of urinary continence recovery after surgery.

Incidence of Ureteroenteric Anastomotic Strictures After Robotic vs Open Cystectomy in Adults.

To synthesise the evidence comparing the incidence rates of UAS post-RARC vs Open Radical cystectomy (ORC) in adults undergoing cystectomy and to compare differential stricture rates between Extracorporeal and Intracorporeal urinary diversion (ECUD vs ICUD). The primary outcome was incidence rate of UAS post RARC vs ORC and the secondary outcome was incidence rate of UAS in RARC post ECUD vs ICUD. Review authors conducted comprehensive search for studies comparing RARC with ORC in terms of incidence of UAS. Furthermore, we conducted a secondary search for studies which compared UAS incidence comparing ECUD and ICUD. We found that RARC may have higher incidence of UAS [OR: 1.39; 95% CI 1.11-1.75; p < 0.0001]. ECUD may result in lower rate of UAS as compared to ICUD [OR: 0.74; 95% CI 0.56 to 0.98; p= 0.04].

Comparison of urological outcomes and quality of life after pelvic exenteration: partial vs radical cystectomy.

OBJECTIVE: To compare perioperative morbidity, functional and quality-of-life (QoL) outcomes in patients with partial cystectomy vs radical cystectomy as part of pelvic exenteration. PATIENTS AND METHODS: Retrospective analysis of a prospectively maintained database of pelvic exenteration patients (1998-2021) was conducted in a single centre. Study outcomes included postoperative complications, quality-of-life, functional and stoma-related outcomes. The 36-item Short-Form Health Survey Physical and Mental Health Components, Functional Assessment of Cancer Therapy-Colorectal questionnaires and Distress Thermometer were available pre- and postoperatively. QoL outcomes were compared at the various time points. Stoma embarrassment and care scores were compared between patients with a colostomy, urostomy, and both. RESULTS: Urological complications were similar between both groups, but patients with partial cystectomy experienced less wound-related complications. Overall, 34/81 (42%) partial cystectomy patients reported one or more long-term voiding complication (i.e., incontinence [17 patients], frequency [six], retention [three], high post-voiding residuals [10], permanent suprapubic catheter/indwelling catheter [14], recurrent urinary tract infection [nine], percutaneous nephrostomy [three], progression to urostomy [three]). The QoL improved following surgery in both the partial and radical cystectomy groups, differences between cohorts were not significant. Patients with two stomas reported higher embarrassment scores than patients with one stoma, although this did not result in more difficulties in stoma care. CONCLUSIONS: Partial cystectomy patients have fewer postoperative wound-related complications than radical cystectomy patients, but often experience long-term voiding issues. The QoL outcomes are similar for both cohorts, with significant improvement following surgery.

Systematic review comparing uretero-enteric stricture rates between open cystectomy with ileal conduit, robotic cystectomy with extra-corporeal ileal conduit and robotic cystectomy with intra corporeal ileal conduit formation.

Cystectomy is the gold standard treatment for muscle invasive bladder cancer. Robotic cystectomy has become increasingly popular owing to quicker post- operative recovery, less blood loss and less post-operative pain. Urinary diversion is increasingly being performed with an intracorporeal technique. Uretero-enteric strictures (UES) cause significant morbidity for patients. UES for open cystectomy is 3-10%, but the range is much wider (0-25%) for robotic surgery. We aim to perform systematic review for studies comparing all 3 techniques, to assess for ureteric stricture rates. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (Page et al. in BMJ 29, 2021). PubMed, Scopus and Embase databases were searched for the period January 2003 to June 2023 inclusive for relevant publications.The primary outcome was to identify ureteric stricture rates for studies comparing open cystectomy and urinary diversion, robotic cystectomy with extracorporeal urinary diversion (ECUD) and robotic cystectomy with intracorporeal urinary diversion (ICUD). Three studies were identified and included 2185 patients in total. The open operation had the lowest stricture rate (9.6%), compared to ECUD (12.4%) and ICUD (15%). ICUD had the longest time to stricture (7.55 months), ECUD (4.85 months) and the open operation (4.75 months). Open operation had the shortest operating time. The Bricker anastomoses was the most popular technique. Open surgery has the lowest rates of UES compared to both robotic operations. There is a learning curve involved with performing robotic cystectomy and urinary diversion, this may need to be considered to decide whether the technique is comparable with open cystectomy UES rates. Further research, including Randomised Control Trials (RCT), needs to be undertaken to determine the best surgical option for patients to minimise risks of UES.
