Robotic-assisted native pyeloureterostomy with indocyanine green, after kidney transplantation.

INTRODUCTION: Postoperative ureteral strictures and vesicoureteral reflux after ureteroneocystostomy for kidney transplant can be managed by endoscopic procedures like balloon dilation and endoscopic injections. Complicated/recurrent cases, however, are usually managed by reconstructive surgery. We hereby highlight our technique of robotic-assisted native pyeloureterostomy with indocyanine green (ICG). MATERIALS AND SURGICAL TECHNIQUE: A 57-year-old woman, diagnosed with grade 4 vesicoureteral reflux on her transplanted kidney, was considered a candidate for ureteral reimplantation. After an endoscopic part, where the ICG is inserted into the renal pelvis, we proceed with the robotic native pyeloureterostomy. The renal pelvis of the transplanted kidney was identified with the help of the ICG in firefly mode. After the dissection of the graft pelvis, we performed a tension-free pyeloureterostomy using the native ureter. The postoperative course was uneventful and the patient was discharged on the third postoperative day. DISCUSSION: Robotic-assisted pyelo-ureterostomy appears as a safe and efficient technique for management of complicated urological complications postrenal transplantation using the native ureter. Intrapelvic ICG injection, not possible with open surgery, helps identifying the grafted pelvis thus reducing operative time and avoiding unnecessary dissection of the vascular hilum of the graft. Because of minimal dissection and the short operative time, abdominal drainage is unnecessary and the postoperative course is usually uneventful with a fast discharge from the hospital.

Robotic-assisted radical cystectomy with cutaneous ureterostomies: a contemporary multicenter analysis.

BACKGROUND: Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy. OBJECTIVE: To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS. METHODS: Patients that underwent RARC + UCS during 2013-2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1. RESULTS: Sixty-nine patients were included. The median age was 77 years (IQR 70-80) and the median follow-up time was 11 months (IQR 4-20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202-290), and the median hospital stay was 8 days (IQR 6-11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively. CONCLUSIONS: RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results.

[Ipsilateral ureteroureterostomy. A safe alternative in complete duplicated collecting system with associated pathology]. / Uretero-ureteroanastomosis distal ipsilateral. Una alternativa segura en doble sistema renal completo con patología asociada.

In patients with complete double renal system with the involvement of only one system, there are several surgical alternatives for its resolution. Uretero-ureteral anastomosis has been presented as a good alternative, even in cases with atrophy of the affected system. OBJECTIVE: To report our experience in patients with complete double renal system with only one system affected, with the surgical technique of uretero-ureteral anastomosis. PATIENTS AND METHOD: Retrospective study of patients with double renal system with involvement of one of the systems, treated with uretero-ureteral anastomosis technique between January 2015 and May 2022. The variables of age, specific pathology of the affected system, preoperative study, days of hospitalization, postoperative complications (leakage, obstruction, infection), and follow-up time were evaluated. RESULTS: We analyzed 26 procedures in 25 patients, mean age 36.8 months (range: 8-80); 53.8% had ectopic ureter, 23% ureterocele, 11.5% sphincteric ureterocele, and 11.5% VUR of the lower system. All were studied preoperatively with urethrocystography and 65% with scintigraphy. 50% of the operated systems showed signs of renal atrophy. The average hospital stay was 2.2 days (range: 1-7). In an average follow-up of 26.5 months (range: 3-77), one patient presented leakage, no patient presented signs suggestive of obstruction, and one patient presented febrile urinary tract infection with persistent lower-grade reflux. CONCLUSION: In our experience, the uretero-ureteral anastomosis technique proved to be an easy and safe alternative to reproduce, with a success rate of 96%, 11% of grade I complications, and 4% of grade II complications according to the Clavien-Dindo classification.

Trasplante renal con ureterostomía cutánea / Renal Transplant with Cutaneous Ureterostomy: A Case Report

Introducción: El trasplante renal precisa de un tratamiento inmunosupresor para evitar el rechazo del injerto, pero éste aumenta el riesgo de contraer una infección. Este riesgo se agrava, aún más, cuando el paciente es portador de una ureterostomía cutánea por la manipulación de las sondas. Descripción Caso Clínico: Varón que ingresa para realización de primer trasplante renal y ureterostomía cutánea. Como antecedentes personales encontramos nefrectomía derecha en 2014 y nefrectomía izquierda y cistectomía radical en 2019, momento en el que comienza en programa de hemodiálisis. Descripción del plan de cuidados: Se realizó valoración inicial y cada 7 días según patrones funcionales de Marjory Gordon. De los diagnósticos identificados a los 15 días se establecieron como prioritarios: Disposición para mejorar los conocimientos, Complicación potencial la infección y Disposición para mejorar el afrontamiento. Evaluación del plan de cuidados: Semanalmente, se revisó el plan de cuidados, cerrando aquellos diagnósticos resueltos. Al alta, tras 33 días ingresado, se alcanzaron los objetivos establecidos, aunque la gran mayoría de ellos se continuaron reevaluando en la Consulta de Enfermería post-trasplante, como fue el diagnóstico de Disposición para mejorar los conocimientos. Conclusiones: Una correcta educación para la salud y la intervención de un equipo interdisciplinar permite un adecua-do aprendizaje de los cuidados fomentando la adherencia terapéutica y una buena prevención y detección precoz de las complicaciones que pueda conllevar la derivación en un paciente trasplantado. Además, ayudar al paciente y a su familia a aceptar esta nueva etapa que conlleva cambios a nivel físico, emocional y social. (AU)

Introduction: Renal transplant requires immunosuppressive treatment to prevent graft rejection, but this increases the risk of infection. This risk is further exacerbated when the patient has a cutaneous ureterostomy due to catheter manipulation. Clinical case description: A male patient was admitted for his first renal transplant and cutaneous ureterostomy. Past medical history includes a right nephrectomy in 2014, a left nephrectomy, and a radical cystectomy in 2019, which led to the initiation of hemodialysis. Nursing care plan description: Initial assessment was conducted, with subsequent evaluations every seven days based on Marjory Gordon’s functional patterns. At the 15-day mark, the following diagnoses were prioritized: Readiness for Enhanced Knowledge, Potential Infection Complication, and Readiness for Enhanced Coping. Evaluation of care plan: The care plan was reviewed weekly, closing out resolved diagnoses. Upon discharge after 33 days of hospitalization, established goals were achieved, with an ongoing revaluation of most of them in the post-transplant Nursing Consultation, particularly the Readiness for Enhanced Knowledge diagnosis. Conclusions: Proper health education and involvement of an interdisciplinary team enable effective learning of care practices, promoting therapeutic adherence and facilitating early prevention and detection of complications that may arise in transplant patients. Additionally, assisting the patient and family in accepting this new phase, which entails physical, emotional, and social changes, is crucial.

Shame in patients undergoing ureterostomy: A cross-sectional survey.

Shame has an important impact on the mental health and quality of life of patients. The shame in patients with ureterostomy after cystectomy remains unclear. This survey aimed to evaluate the status quo and influencing factors of shame in patients with ureterostomy after cystectomy, to provide support for the clinical care. Patients with ureterostomy after cystectomy treated in the wound stomy clinic of a third-class hospital from 1 June 2022 to 31 July 2023 were included. General data questionnaire and social impact scale (SIS) were used for data collection. Univariate and multiple linear regression analysis were performed to evaluate the influencing factors of shame in patients with ureterostomy after cystectomy. One hundred and sixty four patients with ureterostomy after cystectomy were included. The total score of shame in patients with ureterostomy was (60.75 ± 6.31), which was in the high level. Age (r = 0.442), home place (r = 0.427), per capita monthly household income (r = 0.605), self-care ability (r = 0.597) and complications of stoma (r = 0.542) were correlated with the SIS score in patients with ureterostomy after cystectomy (all p < 0.05). Multiple linear regression analyses indicated that age, home place, per capita monthly household income, self-care ability and complications of stoma were the influencing factors of SIS score in patients with ureterostomy after cystectomy (all p < 0.05). The five variables explained 64.5% of the patients' sense of shame variation. Patients with ureterostomy after cystectomy have a serious sense of shame in the early stage after operation and there are many influencing factors. Health care providers should take early nursing interventions targeted on those influencing factors to reduce the patients' sense of shame.

[Retrograde Ureteroscopic Lithotripsy with Ureteral Access Sheath Via Cutaneous Ureterostomy after Urinary Diversion : A Case Report].

A 65-year-old man presented with a history of rectal cancer 20 years prior that led to the development of a cutaneous ureterostomy and a colostomy. Subsequently, the patient was diagnosed with acute complicated pyelonephritis due to a right ureteral stone. After the placement of a single J ureteral stent in the right ureter for therapeutic management, the patient was referred to our institution for treatment of the right ureteral stone. An abdominal computed tomography (CT) revealed an 11×8 mm stone in the upper right ureter. A 10/12 Fr ureteral access sheath was inserted through the cutaneous ureterostomy and retrograde ureteroscopic lithotripsy was performed. Although a febrile urinary tract infection appeared postoperatively, the patient was discharged on the sixth postoperative day. At postoperative 1-month, CT showed no residual stones and no hydronephrosis. The use of a ureteral access sheath in performing retrograde ureteroscopic lithotripsy effectively managed the ureteral stone with cutaneous ureterostomy.

Risk Factors Analysis and Pathogen Distribution of Urinary Tract Infection in Patients Undergoing Cutaneous Ureterostomy After Radical Cystectomy for Bladder Cancer.

BACKGROUND: Postoperative urinary tract infection is a common complication that not only significantly prolongs the hospital stay and amplifies the economic burden on patients, but also affects their quality of life and prognosis. This study aimed to investigate risk factors and distribution of pathogenic bacteria in urinary tract infections among bladder cancer patients who underwent cutaneous ureterostomy following radical cystectomy. METHODS: A total of 137 bladder cancer patients, who underwent cutaneous ureterostomy after radical cystectomy at our hospital from November 2018 to October 2022, were enrolled in this retrospective study. Univariate and multivariate logistic regression analyses were employed to investigate the risk factors associated with postoperative urinary tract infection and the distribution of pathogenic bacteria among the infected patients. RESULTS: The results of both univariate and multivariate analyses confirmed that age, proficiency in ostomy knowledge, frequency of ureteral stent tube replacement, ureteral stent tube dislodgement, urine immersion at the outer end of the ureteral stent tube, and the interval of ostomy bag replacement were independent risk factors for urinary tract infection after radical cystectomy and cutaneous ureterostomy in bladder cancer patients. A total of 55 pathogenic bacteria were isolated from 52 patients with infections. Predominantly, these were gram-negative bacteria (34 strains, 61.8%), with Proteus mirabilis having the highest proportion. CONCLUSION: Urinary tract infections after radical cystectomy and cutaneous ureterostomy predominantly involve gram-negative bacteria. This is correlated with factors such as the age of bladder cancer patients, the level of nursing education, the duration of ureteral stent tubes and ostomy bag usage, as well as issues related to impaired urine drainage.

The effect of body mass index on quality of life in modified single stoma cutaneous ureterostomy or ileal conduit after radical cystectomy.

OBJECTIVE: To explore the influence of postoperative body mass index (BMI) change on postoperative quality of life (QOL) in patients undergoing radical cystectomy (RC) plus modified single stoma cutaneous ureterostomy (MSSCU) or ileal conduit (IC). METHODS: Patients were divided into two groups according to different BMI change patterns: patients experiencing an elevated postoperative BMI level, along with a clinically significant increase in their BMI (an increase of more than 10%) were categorized as Group 1, while patients experiencing a decrease postoperative BMI level, along with a clinically significant reduction in their BMI (a decrease of more than 5%) were categorized as Group 2. Spearman correlation analysis was used to examine the correlations between quality-of-life scores and postoperative clinical parameters. RESULTS: Spearman correlation analysis showed that postoperative BMI, late complications and catheter-free state were significantly associated with postoperative global QoL and symptom scale in MSSCU and postoperative global QoL and physical scale in IC patients. Additionally, postoperative BMI, catheter-free state and the use of adjuvant therapy were associated with bad performance in many scales of QoL like body image, future perspective, social scale, future perspective (MSSCU), and abdominal bloating (IC) (Table 2, p<0.05). Patients in Group 2 with significant weight loss had a better Global QoL, a lower rate of stomal stricture and a higher catheter-free state compared with those in Group 1 in both IC and MSSCU patients. MSSCU patients in Group 2 could achieve a comparable Global QoL as to IC patients in Group 1. CONCLUSION: Controlling the substantial increase in body weight after surgery contributes to improving QoL, reducing the occurrence of stomal stricture, and ensuring a postoperative catheter-free state in BCa patients undergoing MSSCU.

Modified Tubeless Ureterocutaneostomy in High-Risk Patients After Radical Cystectomy and its Long-Term Clinical Outcomes.

OBJECTIVES: This work aimed to prevent stoma stenosis and achieve tubeless cutaneous ureterostomy in elderly and high-risk patients with our modified cutaneous ureterostomy. METHODS: We retrospectively analyzed 40 and 49 patients (176 renal units) who underwent Toyoda (group 1) and modified cutaneous ureterostomy (group 2) between 2012 and 2021. The average follow-up period was 44 months. The primary results of our study were the catheter-free rate and clinical outcomes, especially renal function and urinary diversion-related complications. Significant differences in catheter-free rate and urinary diversion-related complications were found between our modified method and the Toyoda technique. RESULTS: A total of 56 (71.8%) of 78 renal units in group 1 and 89 (90.8%) of 98 renal units in group 2 remained catheter free. Compared with group 1, group 2 had a higher catheter-free rate (P = .001). Multivariate analysis indicated that the surgical procedure (HR = 0.268; P = .001) and body mass index (HR = 3.127; P = .002) were the predictors independently associated with catheter insertion. During follow-up, renal deterioration was observed in 32 (36.0%) patients. Patients with catheter insertion were more likely to suffer from renal deterioration (P < .001), postoperative pyelonephritis (P < .001), and urolithiasis (P < .001) than their counterparts. CONCLUSION: Our modified cutaneous ureterostomy method may provide an effective and simple approach to tubeless cutaneous ureterostomy in elderly and high-risk patients.

Cutaneous Ureterostomy Following Radical Cystectomy for Bladder Cancer: A Contemporary Series.

OBJECTIVE: To report peri-operative outcomes of a contemporary series of bladder cancer patients undergoing radical cystectomy (RC) with cutaneous ureterostomy (CU) urinary diversion at a tertiary referral center. METHODS: We retrospectively identified patients who underwent RC with CU at Mayo Clinic between 2016 and 2021. Clinicopathologic and perioperative characteristics were analyzed using standard descriptive statistics. RESULTS: A total of 31 patients underwent RC with CU at our institution. Median age was 72years and 21 were male. This was highly comorbid cohort (83% had an American Society of Anesthesiologists [ASA] Physical Status Classification System ≥3; median Charlson Comorbidity index= 8). Median time to flatus, tolerating regular diet, and length of stay were 3 (interquartile range [IQR] 3-3), 3 (IQR 3-4), and 4days (IQR 4-7), respectively. A total of 14 patients experienced a high-grade complication (Clavien-Dindo ≥3) within 30days of surgery, and 8 were readmitted. The most common 30-day complication was sepsis, which affected 13% (4/31) of patients. At 90days postsurgery, the readmission rate was 32% (10/31), most commonly for sepsis. Three patients required reoperation within 90days, including one patient who required CU revision due to stomal ischemia. One patient died within this time frame from causes unrelated to bladder cancer. CONCLUSION: In a comorbid, relatively elderly bladder cancer cohort undergoing RC, the use of CU was associated with expeditious surgery and postoperative recovery. CU represents an option for urinary diversion in high-risk patients undergoing RC. Higher rate of postoperative ureteral obstruction can be pre-emptively addressed with chronic stent placement.

Analysis of the efficacy of a single subumbilical stoma for bilateral cutaneous ureterostomy after radical cystectomy.

BACKGROUND: Radical cystectomy and urinary diversion are the standard surgical treatments for patients with muscle-invasive or high-risk, or recurrent non-muscle-invasive bladder cancer. Although this approach significantly prolongs patient survival, it can lead to postoperative complications. This study aims to compare the efficacy and complications of bilateral cutaneous ureterostomy with a single subumbilical stoma to those of cutaneous ureterostomy with two stomas and an ileal conduit as a means of urinary diversion after radical cystectomy. The findings of this study will provide valuable information for healthcare providers in selecting the appropriate urinary diversion method for their patients. METHODS: The clinical data for 108 patients who received bilateral cutaneous ureterostomy with a single subumbilical stoma (ureterostomy with a single stoma group), cutaneous ureterostomy with two stomas (ureterostomy with two stomas group), or an ileal conduit (ileal conduit group) after radical cystectomy were retrospectively analysed. The operative time, pathological stage, survival status, perioperative complication rate, rate of successful first extubation, rehospitalization rate at 6 months after surgery,ostomy-related medical costs,and postoperative quality of life were compared between the three groups of patients. RESULTS: A significant difference in the operative time was found between the three groups (P = 0.001). No significant differences in pathological stage, survival status, perioperative complication rate, rehospitalization rate at 6 months after surgery, or bladder cancer index (BCI) score were identified among the three groups. The difference in the successful first extubation rate between the three groups of patients was significant (P = 0.001). Significant differences in ostomy-related medical costs were observed among the three groups of patients (P = 0.006). CONCLUSION: A single subumbilical stoma for bilateral cutaneous ureterostomy after radical cystectomy may result in shorter surgery time, increased success rates for initial catheter removal, and lower medical expenses. However, to confirm these findings, further prospective randomized clinical trials are necessary.

Primary repair vs Delayed staged repair in infants with primary obstructive megaureters and their long term outcomes - A single centre experience.

BACKGROUND: There is paucity of literature in the management of infants with primary obstructive megaureters undergoing upfront primary repair with an extravesical technique of ureteral re implantation (with or without ureteral tailoring). OBJECTIVE: To compare 2 different approaches in the management of infants with unilateral primary obstructive megaureters. STUDY DESIGN: This was a retrospective analysis of a prospectively maintained data base between 2005 and 2021. Infants <1 year with unilateral primary obstructive megaureter were included. They were divided into 2 groups: those who underwent an upfront extravesical ureteric reimplantation with or without ureteral tailoring during infancy -Primary Repair (PR), and those who initially underwent a low end cutaneous ureterostomy during infancy followed by take down of ureterostomy and intravesical ureteric reimplantation after 1 year of age -Delayed staged repair (DSR). Children presenting with sepsis, in whom a diversion was imperative, were excluded. All children were followed up annually after their definitive repair with a renal ultrasound, diuretic renogram, estimated glomerular filtration rate and assessment of voiding dysfunction if present. The 1st year and 3rd year follow up details were collated and analysed. Failure was defined as persistent obstructive pattern on renogram with worsening differential renal function or presence of high grade reflux with recurrent breakthrough urinary tract infection; both of which necessitated a redo reimplantation following the definitive surgery. RESULTS: There were 18 infants in Primary repair and 16 infants in Delayed Staged Repair. Urinary tract infections was the commonest presenting symptom amongst both groups i.e. > 50%.The post operative complication rate was 11% in Primary repair and 31% in Delayed Staged Repair. One child in each of the groups (2 girls) required redo reimplantation (5.8%). At the end of the 3rd year follow up (from the definitive repair) there was significant reduction in the hydronephrosis, improvement in the differential renal function with no evidence of obstruction and improvement in the estimated glomerular filtration rate amongst all in both groups which was statistically significant i.e. p < 0.05. The success rate was 94.4% in Primary Repair and 93.75% in Delayed Staged Repair. The mean follow up was 9.7 years amongst those undergone Primary Repair and 9 years amongst those undergone Delayed Staged Repair. DISCUSSION AND CONCLUSION: Primary extravesical ureteral reimplantation may be considered as the preferred line of management of unilateral obstructed megaureters during infancy.

Appendicocecal Loop Urinary Diversion in a Transplant Kidney: Case Report, Literature Review.

Urinary diversion in renal transplant patients can take a variety of forms - bladder augmentation, continent cutaneous pouch, or intestinal conduits, to name a few. Herein, we present a unique case of an appendicocecal urinary diversion in a patient with history of end stage renal disease, pelvic radiation, and complex surgical history who underwent deceased-donor renal transplantation. During the renal transplant, the transplant ureterovesical anastomosis could not be performed due to inherent anatomical hindrances. A temporary modified cutaneous ureterostomy using a single-J stent was therefore used for drainage of the transplant kidney. Given that the cutaneous ureterostomy was not a durable, long-term option, we sought to develop a creative surgical solution. This report presents a unique case of urinary diversion post renal transplant and reviews the literature of renal transplantation in patients with anatomical abnormalities.

Application of metagenomic next-generation sequencing in the diagnosis of urinary tract infection in patients undergoing cutaneous ureterostomy.

Objective: Urinary tract infection (UTI) is an inflammatory response of the urothelium to bacterial invasion and is a common complication in patients with cutaneous ureterostomy (CU). For such patients, accurate and efficient identification of pathogens remains a challenge. The aim of this study included exploring utility of metagenomic next-generation sequencing (mNGS) in assisting microbiological diagnosis of UTI among patients undergoing CU, identifying promising cytokine or microorganism biomarkers, revealing microbiome diversity change and compare virulence factors (VFs) and antibiotic resistance genes (ARGs) after infection. Methods: We performed a case-control study of 50 consecutive CU patients from December 2020 to January 2021. According to the clinical diagnostic criteria, samples were divided into infected group and uninfected group and difference of urine culture, cytokines, microorganism, ARGs and VFs were compared between the two groups. Results: Inflammatory responses were more serious in infected group, as evidenced by a significant increase in IFN-α (p=0.031), IL-1ß (0.023) and IL-6 (p=0.018). Clinical culture shows that there is higher positive rate in infected group for most clinical pathogens like Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Candida auris etc. and the top three pathogens with positive frequencies were E. coli, K. pneumoniae, and Enterococcus faecalis. Benchmarking clinical culture, the total sensitivity is 91.4% and specificity is 76.3% for mNGS. As for mNGS, there was no significant difference in microbiome α- diversity between infected and uninfected group. Three species biomarkers including Citrobacter freundii, Klebsiella oxytoca, and Enterobacter cloacae are enriched in infected group based on Lefse. E. cloacae were significantly correlated with IL-6 and IL-10. K. oxytoca were significantly correlated with IL-1ß. Besides, the unweighted gene number and weighted gene abundance of VFs or ARGs are significantly higher in infected group. Notablely, ARGs belonging to fluoroquinolones, betalatmas, fosfomycin, phenicol, phenolic compound abundance is significantly higher in infected group which may have bad effect on clinical treatment for patients. Conclusion: mNGS, along with urine culture, will provide comprehensive and efficient reference for the diagnosis of UTI in patients with CU and allow us to monitor microbial changes in urine of these patients. Moreover, cytokines (IL-6, IL-1ß, and IFN-a) or microorganisms like C. freundii, K. oxytoca or E. cloacae are promising biomarkers for building effective UTI diagnostic model of patients with CU and seriously the VFs and ARGs abundance increase in infected group may play bad effect on clinical treatment.

Robotic ureteral reimplantation and uretero-ureterostomy treating the ureterovesical junction pathologies in children: technical considerations and preliminary results.

Robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR) and robotic ureteroureterostomy (RUU) are two mini-invasive surgical techniques that have begun to be performed in pediatric urology in recent years. RALUR has been employed especially for VUR treatment, while RUU is considered principally in case of complex doubled ureteral systems. Our aim is to discuss the safety and feasibility of these approaches in children, focusing on technical considerations and supporting their use in different anomalies and pathologies of the ureterovesical junction. We retrospectively collected data about 58 patients who underwent 44 dismembered RALUR (D-RALUR), 28 non-dismembered RALUR (ND-RALUR) and 5 RUU between May 2020 and December 2021. Indications for surgery were primary or secondary vesicoureteral reflux, megaureter, secondary UVJ obstructions, complicated doubled ureteral systems. Mean age was 3.5 years (range 0.6-12.9) and mean weight 17.1 (range 7.2-80). No intraoperative complications occurred nor conversion to open approach were reported. Major postoperative complications were reported in 11.7% of cases with a higher incidence for ND-RALUR. Mean hospital stay was 2.14 days (range 1-8). Success rate at the short-term follow-up was 91.9% for D-RALUR, 96.3% for ND-RALUR and 100% for RUU. RALUR and RUU are two feasible and safe procedures to perform in children. RALUR represents the most required and adequate technique in the treatment of UVJ pathologies, however, in selected cases RUU could represent an effective alternative that has to be considered.

Use of an Application to Increase Self-Care Ability, Improve Quality of Life, and Decrease Stoma Complications in Patients With Ileocystoplasty or Ureterostomy Due to Bladder Cancer.

BACKGROUND: Quality of life for patients after ileocystoplasty or ureterostomy due to a urinary bladder neoplasm can be limited after discharge from the hospital. PURPOSE: To add the real-time communication ability of an application (app) to the daily care of this patient population to enhance communication between doctors and patients and provide improved nursing interventions, thus improving patients' self-care abilities and quality of life while decreasing stoma complications. METHODS: A total of 67 patients who underwent urinary tract diversion after total cystectomy were randomly divided into 2 groups. Patients in the control group (n = 32) received regular telephone follow-ups when they were discharged from the hospital, once a week for the first 2 months and then once a month for the next 22 months; patients in the intervention group (n = 35) used an app in addition to receiving regular telephone follow-ups. After 24 months of the intervention, multivariate analyses were conducted regarding self-care ability, complication rate, and quality of life. RESULTS: Self-care ability and quality of life scores in the intervention group were significantly improved during the 24-month period, and the complication rate was significantly reduced. CONCLUSION: Interaction via an app improved patients' self-care ability and quality of life. In addition, stoma complications were reduced. Future studies with larger sample sizes and patients of different ages are needed.

A propensity score matching study on robot-assisted radical cystectomy for older patients: comparison of intracorporeal ileal conduit and cutaneous ureterostomy.

BACKGROUND: Robot-assisted radical cystectomy (RARC) and intracorporeal urinary diversion are less invasive than conventional procedures. However, for older patients, cutaneous ureterostomy (CUS) may be preferred because urinary diversion using the intestine has a high incidence of perioperative complications and is highly invasive. The purpose of this study was to demonstrate the safety and efficacy of intracorporeal ileal conduit (ICIC) compared with CUS in patients aged 75 years or older who underwent RARC. METHODS: From October 2014 to December 2021, 82 patients aged 75 years or older who underwent RARC at Tokushima University Hospital, Tokushima Prefectural Central Hospital, or Ehime Prefectural Central Hospital were retrospectively reviewed. Of these, 52 and 25 patients who underwent ICIC and CUS, respectively, were included. After adjusting the patients' characteristics using propensity score-matching, surgical results and prognoses were retrospectively compared. The propensity score was based on age, Eastern Cooperative Oncology Group Performance Status Scale (ECOG-PS), American Society of Anesthesiologists physical status classification (ASA-PS), clinical tumor stage, and neoadjuvant chemotherapy. RESULTS: The median age was lower in the ICIC group compared with the CUS group, and the proportion of high-risk cases (ECOG-PS ≥ 2 or ASA-PS ≥ 3) did not differ. The median operation time was longer in the ICIC group, and estimated blood loss was higher, compared with the CUS group. There were no significant differences in the incidence of complications within the first 30 postoperative days, incidence of complications 30-90 days after surgery, 2-year overall survival, 2-year cancer-specific survival, and 2-year recurrence-free survival. The stent-free rate was significantly lower in the CUS group than that in the ICIC group. CONCLUSION: In older patients, the ICIC group showed non-inferior surgical and oncological outcomes compared with the CUS group. Urinary diversion following RARC in older patients should be carefully selected by considering not only the age but also the general condition (including comorbidities) of the patient.

Modified Toyoda technique for total cystectomy and cutaneous ureterostomy in a cat.

OBJECTIVES: To report the technique and outcome of a cat treated with a total cystectomy and bilateral cutaneous ureterostomy. ANIMALS: A 16-year-old male castrated domestic shorthair cat. STUDY DESIGN: Case report. CASE PRESENTATION: A cat was referred after a 2-week history of pollakiuria and hematuria. Transitional cell carcinoma (TCC) was suspected based on ultrasonographic, cytologic, and contrast computed tomographic (CT) findings. A total cystectomy was combined with a modified cutaneous ureterostomy: the ureter, incised like a fish-mouth aperture, was anastomosed to the skin after the creation of a rectangular-shaped defect. Complete excision of a TCC was confirmed histologically. RESULTS: Ureteral stents were removed 7 days (left) and 28 days (right) postoperatively. The cat's incontinence was managed with an absorbent diaper surrounding the ureteral stomata. The right ureter became obstructed 14 months after surgery, and the cat died at home approximately 16 months after surgery. In spite of the urinary incontinence, the owner was satisfied with the surgery and evaluated the cat's quality of life as satisfactory. CONCLUSIONS: The total cystectomy and cutaneous ureterostomy described here allowed urinary excretion and resulted in long-term survival of a cat with bladder TCC.
