BACKGROUND: Patients undergoing radical cystectomy with urinary diversions (UD) are at increased risk of bone fractures compared to the general population. Although a loss of bone mineral density (BMD) has been described in patients with UD, we still do not know with certainty why these patients follow this tendency.
OBJECTIVE: We performed a systematic review of the available literature to analyze the prevalence of osteoporosis and bone alterations in patients with ileal UD and the possible associated risk factors.
METHODS: We systematically searched PubMed® and Cochrane Library for original articles published before December 2022 according to PRISMA guidelines.
RESULTS: A total of 394 publications were identified. We selected 12 studies that met the inclusion criteria with 496 patients included. Six of the twelve studies showed decreased BMD values. Prevalence of osteoporosis was specified in three articles, with values ranging ​​from 0% to 36%. Risk factors such as age, sex, body mass index, metabolic acidosis and renal function appear to have an impact on bone tissue reduction, while type of UD, follow-up, 25-hydroxyvitamin D and parathormone had less evidence or contradictory data. The heterogeneity of the studies analyzed could led to interpretation bias.
CONCLUSIONS: UD are associated with multiple risk factors for osteoporosis and bone fractures. Identifying patients at highest risk and establishing diagnostic protocols in routine clinical practice are essential to reduce the risk of fractures and the resulting complications.

OBJECTIVE: To review the different types of urinary diversion surgeries (UDS) in order to recognize the expected findings in a postoperative study, using different imaging techniques. To recognize the main postoperative complications, both early and late.
CONCLUSIONS: UDS are surgical procedures whose purpose is to redirect urine flow after cystectomy, generally in an oncologic context. The imaging evaluation of urological surgeries is often a radiological challenge, with CT being the most commonly used image modality. Therefore, it is essential to know the main surgical techniques, the expected postoperative findings and the optimization of imaging techniques for early diagnosis and correct evaluation of postoperative complications.

The importance of evaluating the self-esteem and quality of life of patients with a chronic disease has become increasingly relevant. The study describes self-esteem and quality of life outcomes in patients with neurogenic dysfunction and continent urinary diversions and/or antegrade enema procedures.
Cross-sectional observational study, including patients with neurogenic dysfunction who required a continent urinary diversion and/or an antegrade enema conduit during their treatment. The self-esteem evaluation was done with the Rosenberg scale and the quality of life with the KIDSCREEN-27 questionnaire.
socio-demographic, clinical and economic characteristics. Descriptive statistics were applied.
The mean age of the 9 patients was 15.6 years, the mean time elapsed from surgery to application of the questionnaires was 60.9 ± 37.1 months. With a perception of improvement in 8 of the 9 patients and a normal or higher self-esteem score in all cases. In the description of physical activity and health, it was found that 7 of the 9 young people presented a perception of good health in general. A considerable reduction in the use of diapers was achieved after the intervention, going from consuming 6.2 ± 1.4 diapers per day to only 1.7 ± 1.3 diapers per day.
Despite the sequelae, comorbidities and procedures, the results of self-esteem and quality of life in patients with neurogenic dysfunction are high.

Metabolic acidosis (MA) is a well-known complication in patients with ileal urinary diversions. It is common in the early postoperative stages and decreases over time. Our objective is to investigate the prevalence of MA after more than one year of follow-up, identify the associated risk factors, and analyze its secondary metabolic consequences.
We conducted an observational study between January 2018 and September 2022 following the STROBE guidelines. MA was defined as a serum bicarbonate level ​​<22mEq/L. Finally, we analyzed 133 patients with a mean follow-up of 55.24 ± 42.36 months.
MA was observed in 16 (12%) patients. Patients with and without MA were comparable in age, sex, and follow-up time. The group with MA presented a higher rate of anemia (68,75% vs 19,65%, p < 0.001) and renal failure (100% vs 45,29%, p < 0.001), statistically significant higher levels of serum creatinine, chloride, potassium, parathyroid hormone, and phosphorus but lower serum values ​​of hemoglobin, renal glomerular filtration rate, total cholesterol, vitamin D, calcium, and albumin (all p < 0.05). Renal glomerular filtration rate was the only independent risk factor related to the development of MA (OR 0.914; 95% CI 0.878-0.95; p < 0.0001), proving a close correlation with venous bicarbonate values ​​(r = 0.387, p < 0.001).
MA is a little prevalent disorder in ileal urinary diversions more than one year after radical cystectomy is performed but it has secondary consequences on hematologic, renal, protein, lipid, and bone metabolism. We recommend to a close follow-up in patients with renal failure for early diagnosis and treatment.

Urine contact with the mucosa of the urinary diversion (UD) after radical cystectomy (RC) produces different ion exchanges that favor the development of metabolic acidosis (MA). This phenomenon is a frequent cause of hospital readmission and short/long-term complications. We performed a systematic review of MA in RCs with ileal UD, analyzing its prevalence, diagnosis, risk factors and treatment. We systematically searched Pubmed® and Cochrane Library for original articles published before May 2022 according to PRISMA guidelines. A total of 421 articles were identified. We selected 25 studies that met the inclusion criteria involving 5811 patients. Obtaining precise data on the prevalence of MA is difficult, largely due to the heterogeneity of the diagnostic criteria used given the diversity of studies analyzed. Development of MA is multifactorial. In the early period, MA is more prevalent in patients with UD with longer ileal segments, better urinary continence, and impaired renal function. Age and diabetes are risk factors associated with MA in later periods. MA is the most common cause of second or more hospital readmissions. Prophylaxis with oral bicarbonate for three months in patients at risk could improve these results. Although MA after ileal UD is a well-known condition, this review highlights the need to implement homogeneous criteria for the diagnosis, follow-up, and treatment, in addition to protocolizing prevention/prophylaxis strategies in patients at risk.

BACKGROUND: Ureteroileal anastomosis stricture is a frequent complication after radical cystectomy and ileal conduit or orthotopic neobladder formation. We analyze their incidence based on the technique for urinary diversion and on the surgical approach (open, laparoscopic or robot-assisted). Stricture management is described, along with surgical outcomes.
METHODS: Descriptive retrospective study over 6 years in patients who underwent urinary diversion using ileum (ileal conduit or orthotopic neobladder). Demographic data, comorbidities, surgical approach, complications, and outcomes were collected. Minimum follow-up of 1 year. Comparison between groups using Chi-square test for dichotomous variables. Quantitative variables were compared using the Student\'s t-test for independent groups or Mann-Whitney test. Statistical significance if P < .05.
RESULTS: The study included 182 patients (84% males and 16% females). Mean age 68 years. Cystectomy approach: laparoscopic (67/37%), robot-assisted (63/35%), open (43/24%). Urinary diversion: ileal conduit (138/76%) and orthotopic ileal neobladder (44/24%). Uretericre implantation technique: Bricker (108/59%) and Wallace (47/26%). Ureteroileal anastomosis strictures (50/27%): bilateral (26), left (16) and right (8). Strictures according to cystectomy approach: laparoscopic (23/46%), robot-assisted (16/32%), open (9/18%). Treatment of strictures (33/18%): ureteric reimplantation (13), indwelling nephrostomy (13), endoscopic dilatation (4), nephroureterectomy (2), endoureterotomy (1). Ureteroileal reimplantation approach: laparoscopic (5/38%), robot-assisted (6/46%), open (2/15%). Outcomes after reimplantation: restenosis (0/0%), reintervention (3/23%), contralateral ureteroileal stricture (1/8%).
CONCLUSIONS: Surgical approach in cystectomy does not influence future development of ureteroileal strictures. Laparoscopic and robot-assisted ureteroileal reimplantation achieves high success rates.

OBJECTIVE: The exstrophy-epispadias complex (EEC) ranges from distal epispadias to cloacal exstrophy, with serious repercussions on the quality of life of patients. However, reconstructive surgery offers the opportunity to reach adulthood and consider motherhood.The objective of this work is to assess the uro-gynecological characteristics and the risks that pregnant women have with EEC. MATERIALS AND METHOD: Retrospective study of 50 patients diagnosed with EEC and treated in a reference center for this pathology, born between 1968 and 2000. Their medical records were reviewed and all demographic, pathological and gynecological data were collected. RESULTS: 37 patients have the inclusion criteria and of these 8 achieved 17 pregnancies (90% spontaneous and 10% through IVF). 10 were successful (50% at term) and 7 were abortions, 87.5% of which were in the first trimester. Urinary tract infection (UTI) was the most frequent complication (41.6%) and the most severe was intestinal occlusion. None of the patients presented renal function impairment during the gestation or dilation of the pathological upper urinary tract (UUT). 62.5% of the patients presented genital prolapses after pregnancies, 80% of which were grade III and IV. 87.5% were dry in the follow-up after their pregnancies. CONCLUSION: Pregnancy in the EEC patients is high risk and it is crucial that the follow-up is carried out by a specialized and integrated multidisciplinary team to minimize complications.
UNASSIGNED: El complejo extrofia-epispadias (CEE) abarca desde las epispadias distales hasta la extrofia de cloaca, con serias repercusiones en la calidad de vida de los pacientes; sin embargo, la cirugía reconstructiva ofrece la oportunidad de llegar a la edad adulta y plantearse la maternidad. El objetivo de este trabajo es valorar las características uro-ginecológicas y los riesgos que presentan las gestantes con CEE. MATERIALES Y MÉTODO: Estudio retrospectivo de 50 pacientes diagnosticadas de CEE y tratadas en un centro de referencia para esta patología, nacidas entre 1968 y 2000. Se revisaron sus historias clínicas y se recogieron todos los datos demográficos, patológicos  y ginecológicos.
UNASSIGNED: 37 pacientes cumplían los criterios de inclusión y de estas 8 lograron 17 embarazos (90% espontáneos y 10% mediante FIV). 10 fueron exitosos (50% a término) y 7 fueron abortos, 87,5% de los cuales fueron en el primer trimestre. La infección urinaria (ITU) fue la complicación más frecuente (41,6%) y la más severa fue la oclusión intestinal. Ninguna de las pacientes presentó deterioro de la función renal durante la gestación o dilatación del tracto urinario superior (TUS) patológica. 62,5% de las pacientes presentaron prolapsos genitales posteriores a los embarazos, 80% de los cuales fueron grado III y IV. 87,5% se encontraban secas en el seguimiento posterior a sus embarazos. CONCLUSIÓN: El embarazo en el CEE es de alto riesgo y es crucial que el seguimiento sea llevado a cabo por un equipo multidisciplinar especializado e integrado para minimizar las complicaciones.

To compare perioperative outcomes and complications of robot assisted radical cystectomy (RARC) with extracorporeal (ECUD) vs. intracorporeal urinary diversion (ICUD) for bladder cancer.
Retrospective revision of 43 patients who underwent RARC for bladder cancer between 2015-2018 with at least 3 months of follow-up. The analysis included the initial series of RARC performed by one surgeon with extensive experience in open radical cystectomy.
Forty-three patients, 40 men (93%) and 3 women (7%), with a median age of 65 years (44-83) and mean follow-up of 27.7 months (±20.1) underwent RARC. A ECUD was performed in 22 cases (51%), of whom 10 were ileal conduits (45.5%) and 12 neobladders (54.5), and ICUD in 21 cases (49%), of whom 14 were ileal conduits (66.7%) and 7 neobladders (33.3%). Clinical and preoperative characteristics were similar in both groups. The median operative time was 360 minutes (240-540) and length of hospital stay was 12 days (7-73). Thirty-five patients (81%) had postoperative complications, of whom 10 (23%) were major. Operative time, peroperative complications, pathological stage, positive margins, and number of lymph nodes removed did not significantly differ among groups. Patients who underwent ECUD had a higher rate of uretero-ileal strictures than those with ICUD (45.5% vs. 14.3%, P=.026). Among the neobladders, the ECUD developed a higher rate of urethro-neobladder stricture than the ICUD (33% vs. 0%, P=.044).
RARC with ICUD achieved peroperative outcomes and complication rates comparable than those with ECUD. The ICUD could reduce the risk of developing uretero-ileal and urethro-neobladder strictures.

There has been growing  interest in intracorporeal techniques to urinary diversion during cystectomy in the modern area. There is little high-quality evidence that this technique is superior to  extracorporeal diversion in patients who are obtaining  an orthotopic intracorporeal neobladder urinary diversion. This study describes the proposed advantages and  disadvantages of intracorporeal orthotopic neobladder urinary diversion and expert opinion on preference.  METHODS: We reviewed the literature for all studies  discussing the outcomes and advantages of intracorporeal orthotopic neobladder urinary diversion, including those comparing the intracorporeal and extracorporeal approach. The studies were reviewed and these findings were summarized based on categories of the proposed advantages and disadvantages of the intracorporeal approach. We provided an assessment of the claims made in favor of the intracorporeal approach and discussed advantages of the extracorporeal approach that may persuade even the most experienced robotic surgeons to lean away from the former.  RESULTS AND CONCLUSIONS: Herein we review the studies that propose advantages of the intracorporeal diversion, as well as the studies that do not demonstrate any advantage to this approach. Some of the proposedadvantages addressed include decreased stricture rate, lower complications and shorter hospitalization. Furthermore, we address the issues of the steep learningcurve and the impact on resident education. We conclude that the proposed benefits of an intracorporeal approach to urinary diversion are not substantiated and it is the preference of the authors to primarily perform extracorporeal urinary diversions.
