Additional Surgeries after Bladder Augmentation in Patients with Spina Bifida in the 21st Century.

PURPOSE: We determined the long-term risks of additional surgery after bladder augmentation in a modern spina bifida cohort accounting for differential followup. MATERIALS AND METHODS: We retrospectively reviewed patients with spina bifida who were born after 1972 and were followed at our institution after augmentation surgery performed between 1979 and 2018. Outcomes included diversion, bladder stones, perforation, reaugmentation, laparotomy for bowel obstruction, and benign and malignant bladder tumors. Survival analysis was used for the entire cohort and the modern cohort (detubularized and reconfigured ileocystoplasty beginning in 2000). RESULTS: A total of 413 patients were included in the study. At a median followup of 11.2 years 80.9% of the patients had undergone ileocystoplasty and 44.1% had undergone 370 additional surgeries. Ten-year risk of any reoperation was 43.9%, with 17.4% of patients undergoing 2 or more and 9.9% undergoing 3 or more additional surgeries. Outcomes included conversion to a diversion (2.7% at 10-year followup) and bladder stones (28.2% with recurrence in 52.4%) irrespective of detubularized reconfigured status (p ≥0.20). Bladder perforation risk was 9.6% for patients undergoing vs 23.7% for those not undergoing detubularized reconfigured ileocystoplasty (p=0.01). Similarly reaugmentation rate was 5.3% for patients undergoing vs 15.2% for those not undergoing detubularized reconfigured ileocystoplasty (p=0.001). Finally, 10-year reperforation risk was 32.1% for patients undergoing vs 73.8% for those not undergoing detubularized reconfigured ileocystoplasty (p=0.053). Other risks included bowel obstruction (4.5% with recurrence in 15.8%), nephrogenic adenoma (2.2% with regrowth in 48.2%) and malignancy (0.0% at 20 years). For 222 patients in the modern cohort (median followup 9.1 years) 10-year risk of any reoperation was 46.0%, which consisted of diversion in 4.0%, stones in 32.9% (recurrence in 44.5%), perforation in 8.8% (recurrence in 42.2%), reaugmentation in 4.3%, obstruction in 4.9% (recurrence in 10.0%), adenoma in 4.7% (regrowth in 40.0%) and cancer in 0.0%. CONCLUSIONS: Bladder augmentation is long-lasting. While benefiting continence and renal outcomes, this operation frequently requires additional surgeries, necessitating close followup. Since survival analysis based risks of alternative management options such as incontinent diversion are unavailable, comparisons with augmentation are unfeasible.

Pregnancy and Delivery in Women with Lower Urinary Tract Reconstruction: A National Multicenter Retrospective Study from the French-Speaking Neuro-Urology Study Group (GENULF) and the Neuro-Urology Committee of the French Association of Urology.

PURPOSE: Management of pregnancy and delivery in women with lower urinary tract reconstruction is challenging and the currently available literature is insufficient to guide clinical practice. We report pregnancy and delivery outcomes in this specific population. MATERIALS AND METHODS: We conducted a national multicenter retrospective study (16 centers) including 68 women with 96 deliveries between 1998 and 2019. These women had at least 1 successful pregnancy and delivery after augmentation enterocystoplasty, catheterizable channel creation and/or artificial urinary sphincter implantation. Maternal and fetal complications during pregnancy and delivery were reported, as well as postpartum functional outcomes, according to the delivery mode. The chi-square test and Student's t-test were used to compare categorical and continuous variables, respectively. RESULTS: Overall 32% of reported pregnancies were complicated by febrile urinary tract infections, 13.5% by renal colic and 14.6% required upper urinary tract diversion. In addition, 10% of patients reported transient self-catheterization difficulties and 13.5% reported de novo or increased urinary incontinence. The preterm delivery rate was 35.3%. Elective C-section was performed in 61% of pregnancies. Twenty complications occurred during delivery (20%), including 19 during elective C-section. Urinary continence at 1 year was unchanged for 93.5% of deliveries. Delivery mode (p=0.293) and multiparity (p=0.572) had no impact on urinary continence. CONCLUSIONS: In this population C-section appeared to be associated with a high risk of complications. In the absence of any obstetric or neurological contraindications, vaginal delivery should be proposed as the first line option to the majority of these women.

Comparison of postoperative complications and quality of life between patients undergoing continent versus non-continent urinary diversion after pelvic exenteration for gynecologic malignancies.

BACKGROUND: Pelvic exenteration and its reconstructive techniques have been associated with high postoperative morbidity and a negative impact on patient quality of life. The aim of our study was to compare postoperative complications and quality of life in patients undergoing continent compared with non-continent urinary diversion after pelvic exenteration for gynecologic malignancies. METHODS: We designed a multicenter study of patients from 10 centers who underwent an anterior or total pelvic exenteration with urinary reconstruction for histologically confirmed persistent or recurrent gynecologic malignancy after previous treatment with radiotherapy. From January 2005 to September 2008, we included patients retrospectively, and from September 2008 to May 2009, patients were included prospectively which allowed collection of quality of life data. Demographic, surgical, and follow-up data were analyzed. Postoperative complications were classified according to the Clavien-Dindo classification. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC)-QLQ-C30 (V.3.0) and EORTC-QLQ-OV28 quality of life questionnaires. We compared patients who underwent a continent urinary diversion with those who underwent a non-continent reconstruction. RESULTS: We included 148 patients, 92 retrospectively and 56 prospectively. Among them, 77.4% had recurrent disease and 22.6% persistent disease after the primary treatment. In 70 patients, a urinary continent diversion was performed, and 78 patients underwent a non-continent diversion. Median age of the continent and incontinent groups was 53.5 (range 33-78) years and 57 (26-79) years, respectively. There were no significant differences between the continent and non-continent groups in median length of hospitalization (28.5 vs 26 days, P=0.19), postoperative grade III-IV complications (42.9% vs 42.3%, P=0.95), complications needing surgical (27.9% vs 34.6%, P=0.39) or radiological (14.7% vs 12.8%, P=0.74) intervention, and complication type (digestive (23.2% vs 16.7%, P=0.32) and urinary (15.9% vs 16.7%, P=0.91)). There were no significant differences between the groups in global health, global quality of life, and body image perception scores 1 year after surgery. CONCLUSION: Continent and incontinent urinary reconstructions are equivalent in terms of postoperative complications and quality of life scores.

Probability of Bladder Augmentation, Diversion and Clean Intermittent Catheterization in Classic Bladder Exstrophy: A 36-Year, Multi-Institutional, Retrospective Cohort Study.

PURPOSE: We assessed the probability of bladder augmentation/diversion and clean intermittent catheterization in classic bladder exstrophy in a multi-institutional cohort. MATERIALS AND METHODS: We included children born from 1980 to 2016 with bladder exstrophy and treated across 5 centers (exclusion criteria less than 1 year followup after birth, isolated epispadias, bladder exstrophy variants etc). Outcomes were probability of bladder augmentation/diversion after bladder closure and proportion of patients performing clean intermittent catheterization at last followup. Survival analysis was used. RESULTS: Of 216 patients 63.4% were male (median followup 14.4 years). Overall 4 patients (1.9%) underwent primary diversion and 212 underwent primary closure (72.6% in first week of life). After primary closure 50.9% underwent augmentation, 4.7% diversion and 44.8% neither. By age 18 years 88.5% underwent a bladder neck procedure (synchronous augmentation 27.3%). On survival analysis the probability of bladder augmentation/diversion was 14.9% by age 5 years, 50.7% by 10 years and 70.1% by 18 years. Probability of bladder augmentation/diversion varied significantly between centers (p=0.01). Probability of bladder augmentation/diversion was 60.7% 10 years after bladder neck procedure. At last followup of the entire cohort 67.4% performed clean intermittent catheterization. Among 95 patients with intact native bladders 30.5% performed clean intermittent catheterization (channel 72.4%). Among 76 adults without a diversion 85.5% performed clean intermittent catheterization (augmented bladder 100.0% clean intermittent catheterization, native bladder 31.3%). Fifteen patients underwent diversion (continent 8, ureterosigmoidostomy 5, incontinent 2). CONCLUSIONS: On long-term followup probability of bladder augmentation/diversion increased with age, with 1 in 2 patients by age 10 years and the majority in adulthood. Probability of bladder augmentation/diversion differed among institutions. Almost a third of patients, including adults, with a closed native bladder performed clean intermittent catheterization. Considering all adults only 14% did not perform clean intermittent catheterization.

Assessment of complications following urinary diversion for benign indications.

INTRODUCTION: To evaluate complications following urinary diversion for non-malignant conditions. MATERIALS AND METHODS: We performed a retrospective review of patients undergoing urinary diversion for benign indications between 2000 and 2017. Data collected including patient demographic and clinical characteristics, surgical characteristics, and complications. Complications were graded using Clavien-Dindo classification and were categorized as early versus delayed (≤ versus > 90 day postoperatively). Logistic regression assessed for predictors of developing any postoperative complication. RESULTS: A total of 68 patients were identified for study analysis with median follow up of 24 (7-72) months. Sixty-eight and 25% of patients underwent diversion for neurogenic bladder and complications related to pelvic radiation, respectively. A majority (90%) underwent ileal conduit with the remainder undergoing continent diversion. A total of 121 complications were identified, comprising 50 early and 72 delayed. Overall, 77% of patients had at least one complication during the follow up period. Fifty-one percent of patients experienced early complication, while 66% of patients experienced delayed complications. Complications of Clavien-Dindo Score ≥ IIIB were seen in 48% of patients. The most common early complication was wound infection (12%); delayed was urinary tract infection (39%). Multivariable logistic regression modeling found no independent predictors of complication, although the best-fit model included BMI, diabetes, presence of multiple comorbidities, and operative time (hr) as positive predictors of complication. CONCLUSION: Our study demonstrates that urinary diversion for benign etiologies is associated with a significant rate of complication. A large percentage of these complications occur in the delayed period and are classified as severe complications.

Robot-Assisted Radical Cystectomy with Intracorporeal Orthotopic Ileal Neobladder: A Safe Strategy in Elderly Patients? Results of Propensity Score Matching in a Single High-Volume Center.

AIM: To compare surgical, functional and early survival outcomes for robot-assisted radical cystectomy (RARC) with intracorporeal orthotopic neobladder (ONB) reconstruction in patients age = 75 y to those in patients age < 75 y using Propensity Score Matching. METHODS: We collected data from 15 patients age = 75 y from among 60 consecutive RARC with ONB reconstruction performed at our institution from January 2015 to July 2018. All procedures were performed by a single surgeon after modular training under the supervision of a skilled surgeon. Demographic, surgical, functional and survival data were prospectively collected and compared to the corresponding data from 15 patients from the same series age < 75 y, matched according to the ASA score, body mass index, clinical stage and associated carcinoma in situ using Propensity Score Matching. RESULTS: There were no significant differences between the two groups with regard to preoperative parameters, such as ASA score, BMI and preoperative stage. The same homogeneity was found for intraoperative parameters, such as operation time, number of nodes retrieved and ONB time. The only statistically significant difference noted was in the percentage of nerve-sparing procedures, which was higher in the younger patient group (p < 0.001). The percentages of early and late postoperative complications were higher in the older patients, but the differences were not statistically significant. Moreover, there were no differences among the two populations in terms of functional outcomes (daytime and nighttime continence, potency), or in either cancer-specific or overall mortality. CONCLUSIONS: RARC with totally intracorporeal ONB diversion can be offered to older patients with an expectation of good surgical, functional and early survival outcomes, although further studies with a larger sample size will be needed to confirm these results.

Outcomes of Intracorporeal Urinary Diversion after Robot-Assisted Radical Cystectomy: Results from the International Robotic Cystectomy Consortium.

PURPOSE: This study aimed to provide an update and compare perioperative outcomes and complications of intracorporeal and extracorporeal urinary diversion following robot-assisted radical cystectomy using data from the multi-institutional, prospectively maintained International Robotic Cystectomy Consortium database. MATERIALS AND METHODS: We retrospectively reviewed the records of 2,125 patients from a total of 26 institutions. Intracorporeal urinary diversion was compared with extracorporeal urinary diversion. Multivariate logistic regression models using stepwise variable selection were fit to evaluate preoperative, operative and postoperative predictors of intracorporeal urinary diversion, operative time, high grade complications and 90-day hospital readmissions after robot-assisted radical cystectomy. RESULTS: In our cohort 1,094 patients (51%) underwent intracorporeal urinary diversion. These patients demonstrated shorter operative time (357 vs 400 minutes), less blood loss (300 vs 350 ml) and fewer blood transfusions (4% vs 19%, all p <0.001). They experienced more high grade complications (13% vs 10%, p = 0.02). Intracorporeal urinary diversion use increased from 9% of all urinary diversions in 2005 to 97% in 2015. Complications after this procedure decreased significantly with time (p <0.001). On multivariable analysis higher annual cystectomy volume (OR 1.02, 95% CI 1.01-1.03, p <0.002), year of robot-assisted radical cystectomy (2013-2016 OR 68, 95% CI 44-105, p <0.001) and American Society of Anesthesiologists® score less than 3 (OR 1.75, 95% CI 1.38-2.22, p <0.001) were associated with undergoing intracorporeal urinary diversion. The procedure was associated with a shorter operative time of 27 minutes (p = 0.001). CONCLUSIONS: The use of intracorporeal urinary diversion has increased in the last decade. A higher annual institutional volume of robot-assisted radical cystectomy was associated with intracorporeal urinary diversion as well as with shorter operative time. Although intracorporeal urinary diversion was associated with higher grade complications than extracorporeal urinary diversion, they decreased with time.

Urinary Diversion After Radical Cystectomy for Bladder Cancer: Comparing Trends in the US and Germany from 2006 to 2014.

OBJECTIVE: Our aim was to assess and compare trends of urinary diversion (UD) for patients receiving radical cystectomy for the treatment of bladder cancer in the US and Germany, and to investigate decisive predictors for the choice of UD. METHODS: We analyzed the nationwide German hospital billing database and the Nationwide Inpatient Sample (NIS) from 2006 to 2014. Cases with a bladder cancer diagnosis combined with RC were included, and trends in the choice of UD, transfusion rates, length of stay, and mortality were assessed. RESULTS: From 2006 to 2014, the total number of RCs recorded within the NIS were 17,711, with a varying annual caseload of 1666-2009, while RC numbers increased from 5627 to 7390 in Germany (p < 0.001 for trends), with a total of 60,447 cases. The share of incontinent UD in the US remained stable at 93%, while increasing from 63.2 to 70.8% in Germany. Multivariate models indicated age and sex were the most important factors associated with the choice of UD in both countries, while hospital caseload and teaching status were less relevant factors in the US. In-hospital mortality was lower in the US compared with Germany (1.9% vs. 4.6%; p < 0.001), with significantly shorter hospital stays (10.7 days in the US vs. 25.1 days in Germany; p < 0.001). CONCLUSIONS: The increasing age of patients with presumably higher comorbidity in recent years led to increased use of incontinent UD in Germany, while continent UD appears to be underused in the US. Mortality and transfusion rates were significantly lower in the US within a shorter hospital stay.

Open radical cystectomy in England: the current standard of care - an analysis of the British Association of Urological Surgeons (BAUS) cystectomy audit and Hospital Episodes Statistics (HES) data.

OBJECTIVE: To establish the current standard for open radical cystectomy (ORC) in England, as data entry by surgeons performing RC to the British Association of Urological Surgeons (BAUS) database was mandated in 2013 and combining this with Hospital Episodes Statistics (HES) data has allowed comprehensive outcome analysis for the first time. PATIENTS AND METHODS: All patients were included in this analysis if they were uploaded to the BAUS data registry and reported to have been performed in the 2 years between 1 January 2014 and 31 December 2015 in England (from mandate onwards) and had been documented as being performed in an open fashion (not laparoscopic, robot assisted or the technique field left blank). The HES data were accessed via the HES website. Office of Population Censuses and Surveys Classification of Surgical Operations and Procedures version 4 (OPCS-4) Code M34 was searched during the same 2-year time frame (not including M34.4 for simple cystectomy or with additional minimal access codes Y75.1-9 documenting a laparoscopic or robotic approach was used) to assess data capture. RESULTS: A total of 2 537 ORCs were recorded in the BAUS registry and 3 043 in the HES data. This indicates a capture rate of 83.4% of all cases. The median operative time was 5 h, harvesting a median of 11-20 lymph nodes, with a median blood loss of 500-1 000 mL, and a transfusion rate of 21.8%. The median length of stay was 11 days, with a 30-day mortality rate of 1.58%. CONCLUSIONS: This is the largest, contemporary cohort of ORCs in England, encompassing >80% of all performed operations. We now know the current standard for ORC in England. This provides the basis for individual surgeons and units to compare their outcomes and a standard with which future techniques and modifications can be compared.

Hospitalisation and readmission costs after radical cystectomy in a nationally representative sample: does urinary reconstruction matter?

OBJECTIVE: To investigate the impact of continent urinary diversion on readmissions and hospital costs in a nationally representative sample of radical cystectomies (RCs) performed in the USA. PATIENTS AND METHODS: The 2010-2014 Nationwide Readmissions Database was queried for patients with a diagnosis of bladder cancer who underwent RC. We identified patients undergoing continent (neobladder or continent cutaneous reservoir) or incontinent (ileal conduit) diversions. Multivariable logistic regression models were used to identify predictors of 90-day readmission, prolonged length of stay, and total hospital costs. RESULTS: Amongst 21 126 patients identified, 19 437 (92.0%) underwent incontinent diversion and 1 689 (8.0%) had a continent diversion created. Continent diversion patients were younger, healthier, and treated at high-volume metropolitan centres. Continent diversions resulted in fewer in-hospital complications (37.3% vs 42.5%, P = 0.02) but led to more 90-day readmissions (46.5% vs 39.6%, P = 0.004). In addition, continent diversion patients were more often readmitted for infectious complications (38.7% vs 29.4%, P = 0.004) and genitourinary complications (18.5% vs 13.0%, P = 0.01). On multivariable logistic regression, patients with a continent diversion were more likely to be readmitted within 90 days (odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.28, 1.88) and have increased hospital costs during initial hospitalisation (OR 1.99, 95% CI: 1.52, 2.61). Continent diversion led to a $4 617 (American dollars) increase in initial hospital costs ($36 640 vs $32 023, P < 0.001), which was maintained at 30 days ($48 621 vs $44 231, P < 0.001) and at 90 days ($56 380 vs $52 820, P < 0.001). CONCLUSION: In a nationally representative sample of RCs performed in the USA, continent urinary diversion led to more frequent readmissions and increased hospital costs. Interventions designed to address specific outpatient issues with continent diversions can potentially lead to a significant decrease in readmissions and associated hospital costs.

Quality of Life in Women After Pelvic Exenteration for Gynecological Malignancies: A Multicentric Study.

OBJECTIVES: This retrospective, multicentric study investigates quality-of-life issues and emotional distress in gynecological cancer survivors submitted to pelvic exenteration (PE). METHODS: The Global Health Status scale of European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30; the EORTC QLQ-CX24 (CX24), and EORTC QLQ-OV28 questionnaires were administered at least 12 months from surgery only in women with no evidence of further recurrence after PE. Statistical analysis was performed by the analysis of variance (for repeated measures. RESULTS: Ninety-six subjects affected by gynecological malignancies receiving PE were enrolled in the study. Anterior PE was performed in 47 patients (49%), posterior PE was performed in 29 cases (30.2%), and total PE performed in 20 women (20.8%). In 38 cases (39.6%), a definitive colostomy was performed. Urinary diversion with continent pouch was created in 11 patients. (11.5%), whereas in the remaining cases, a noncontinent pouch was reconstructed. Patients showed a significant discomfort in attitude to disease (71.5 ± 4.7), body image (48.9 ± 6.4), financial difficulties (56.2 ± 5.8), gastrointestinal symptoms (constipation, 47.8 ± 5.1; diarrhea, 62.4 ± 6.6; appetite loss, 43.6 ± 6.7), insomnia (64.5 ± 6.6), Global Health Status (64.6 ± 3.8), physical functioning (65.8 ± 4.6), role functioning (58.8 ± 5.8), and emotional functioning (67.4 ± 4.2). A higher number of ostomies (hazard rate [HR], 7.613; P = 0.012), the creation of a noncontinent bladder (HR, 8.230; P = 0.009), and of definitive colostomy (HR, 8.516; P = 0.008) emerged as independent predictors of poorer Global Health Status scores. Older age (HR, 11.235; P = 0.003), vaginal/vulvar cancer (HR, 7.369; P = 0.013), total/posterior PE (HR, 7.393; P = 0.013), higher number of ostomies (HR, 7.613; P = 0.012), the creation of a noncontinent bladder (HR, 8.230; P = 0.009), and of definitive colostomy (HR, 8.516; P = 0.008) emerged as independent predictors of lower body image levels. CONCLUSIONS: Long-term psycho-oncological support is strongly recommended. The reduction of ostomies seems the most effective way to improve patients' quality of life.

Cystectomy for benign disease: readmission, morbidity, and complications.

INTRODUCTION: We sought to elucidate outcomes and risks associated with cystectomy and urinary diversion for benign urological conditions compared to malignant conditions. MATERIALS AND METHODS: We identified patients who underwent cystectomy and urinary diversion for benign and malignant diseases through the American College of Surgeons National Surgery Quality Improvement Program database for the period 2007-2015. Patients were selected for inclusion based upon their current procedure terminology and International Classification of Disease, Ninth revision codes. Primary outcome was 30 day morbidity including return to the operating room (OR); infectious, respiratory, and/or cardiovascular complications; readmission to the hospital; and mortality. Multivariable regression analyses were performed to identify associated factors. RESULTS: A total of 317 patients underwent cystectomy and urinary diversion for benign disease, and 5510 patients underwent radical cystectomy with urinary diversion for cancer. Rates of major morbidity (43.2% versus 38.6%), mortality (0.9% versus 1.9%), return to OR (5% versus 5.8%), readmission (19.7% versus 21.4%), postoperative sepsis (14.5% versus 12%), and wound complications (16.1% versus 14.2%) were similar among patients undergoing cystectomy for benign and malignant conditions. In the group with cystectomy for benign conditions, smoking (OR: 3.11) and longer operative duration (OR: 1.06) were significantly associated with increased overall morbidity. Wound complications were significantly higher in smokers (OR: 3.09) and with an ASA ≥ III (OR: 5.71) CONCLUSIONS: Patients undergoing cystectomy and urinary diversion for benign disease are at similar risk for 30 day morbidity and mortality as patients undergoing surgery for malignant conditions. Risk factors are identified that can potentially be targeted for morbidity reduction.

Incisional hernia after cystectomy: incidence, risk factors and anthropometric predisposition.

INTRODUCTION: Postoperative incisional hernias (PIH) are an established complication of abdominal surgery with rates after radical cystectomy (RC) poorly defined. The objective of this analysis is to compare rates and risk factors of PIH after open (ORC) and robotic-assisted (RARC) cystectomy at a tertiary-care referral center. MATERIALS AND METHODS: We performed a retrospective review of patients undergoing ORC and RARC from 2000-2015 with pre and postoperative cross-sectional imaging available. Images were evaluated for anthropometric measurements and presence of postoperative radiographic PIH (RPIH). Patient demographics, type of urinary diversion and postoperative hernia repair (PHR) were also assessed. RESULTS: Of the patients that met inclusion criteria (n = 469), the incidence of RPIH and PHR were 14.3% and 9.0%, respectively. Between ORC and RARC, analysis revealed no statistically significant differences in rates of RPIH (13.6% versus 20.3%, p = 0.152) or PHR (8.2% versus 12.5%, p = 0.214). Body mass index was associated with a slightly increased likelihood of RPIH on univariate analysis alone (OR 1.08, p = 0.008). Ileal conduit was associated with a decreased likelihood of RPIH (OR 0.42, p = 0.034) and PHR (OR 0.36, p = 0.023). Supraumbilical rectus diastasis width (RDW) was an independent predictor of both RPIH (OR 1.52, p = 0.023) and PHR (OR 1.43, p = 0.039) on multivariate analysis. CONCLUSIONS: Patients undergoing RC are at significant risk of RPIH and PHR regardless of surgical approach. Anthropomorphic factors and urinary diversion type appear to be associated with PIH risk. Further research is needed to understand how risks of PIH can be reduced in patients undergoing cystectomy.

[Appendicovesicostomy (Mitrofanoff procedure) in children: Long-term follow-up and specific complications]. / Dérivations urinaires continentes trans-conduit selon Mitrofanoff chez l'enfant : suivi à long terme et complications spécifiques.

OBJECTIVE: In children, intermittent catheterization by appendicovesicostomy according to Mitrofanoff is an interesting alternative to the urethral approach. Objective of the study was to evaluate the rate of appendicovesicostomy's specific complications. METHOD: From 1997 to 2017, data on children treated and followed for an appendicovesicostomy in an academic institution were collected retrospectively. Rates of surgical complications specifically encountered on appendicovesicostomy, time of onset, frequency, and necessity of surgical reinterventions have been reported. RESULTS: Thirty-four patients were operated on and followed for a median of 6.2 years [0.3-24]. Fifty percent had a complication, occurring after a median of 8 months [2-90], and 38% required at least one surgical revision. If complication occurred, adjustment of medical treatment and intermittent catheterization was effective in 12% of patients, endoscopic or over-fascial surgery was necessary in 17% of cases, and under-fascial revision in 21% of cases. Median time to complication was 4 months [1-90] after creation or revision of appendicovesicostomy. Thirty-height percent of difficult channel catheterization were reported, of which 46% were over or under-fascial stenosis. Inaugural urinary incontinence was 18%, and only 9% if using the appendix. At the end, 97% of appendicovesicostomy were continent. CONCLUSIONS: Appendicovesicostomy is a high risk of complications and postoperative revisions surgery, in order to have a functional continent channel. LEVEL OF EVIDENCE: 4.

Impact of body mass index on robot-assisted radical cystectomy with intracorporeal urinary diversion.

OBJECTIVES: To determine the impact of body mass index (BMI) on peri-operative and oncological outcomes after robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion. PATIENTS AND METHODS: A total of 216 patients undergoing RARC, extended lymphadenectomy and intracorporeal urinary diversion, between July 2010 and December 2015, were categorized into four BMI groups according to the 2004 World Health Organization obesity classification groups: <25 kg/m2 (normal); 25-29.9 kg/m2 (pre-obese); 30-34.9 kg/m2 (obese class I); and ≥35 kg/m2 (obese class II). Pre-, intra- and postoperative characteristics, oncological outcomes, and 90-day complications were compared using sas statistical software. RESULTS: All 216 patients underwent intracorporeal urinary diversion, with 68 (32%) undergoing orthotopic neobladder construction. Demographics were similar among the BMI groups with regard to median (range) age (71.8 [35- 95] years), gender (80.6% men), Charlson comorbidity index (CCI) score (66.2% with CCI score 0-1), pathological stage (carcinoma in situ to T2: 55.1%, T3-T4/N0: 18.5%, Tx/N+: 26.4%), median (interquartile range) node count [41 (28, 53)] and positive soft tissue margin rate (4.2%). Obese patients had greater blood loss and longer operating time (P = 0.02 and P = 0.04, respectively). There were no significant differences in length of hospital stay, transfusion rates, readmission or 90-day overall and high-grade complication rates (P = 0.16, P = 0.96, P = 0.89, P = 0.22 and P = 0.51, respectively). At a median (range) follow-up of 13 months (15 days to 4.8 years), recurrence-free survival (P = 0.92) and overall survival (P = 0.68) were similar among the groups. CONCLUSION: The results of the present study show that RARC with intracorporeal urinary diversion is safe and feasible in obese patients with bladder cancer. BMI was not associated with significant differences in peri-operative, pathological or early oncological outcomes.

Radiation-induced complex anterior urinary fistulation for prostate cancer: a retrospective multicenter study from the Trauma and Urologic Reconstruction Network of Surgeons (TURNS).

PURPOSE: To characterize anterior urinary fistulae following radiotherapy for prostate cancer. METHODS: Over 10 years, 31 men were identified to have an anterior urinary fistula. A retrospective database was created to evaluate patient demographics, presentation, diagnostic procedures, operative interventions, outcomes, and complications. Comparisons between men who underwent cystectomy versus bladder-sparing surgeries were performed. RESULTS: At a median age of 73 (interquartile range (IQR) 68.5, 79) years, presenting symptoms included as follows: pubic pain (19/31, 61%), urine drainage via fistula (10/31, 32%), or a superficial wound infection (6/31, 19%). Recent instrumentation prior to diagnosis of anterior urinary fistula was reported by 18/31 (58%) at a median of 14.9 months (IQR 7.9, 103.8) after manipulation. Anterior fistula formation was either isolated to the pubic symphysis (19/31, 61%) or the thigh (12/31, 38%). Nineteen men underwent a cystectomy, whereas 12 men underwent a fistula repair. Excluding grades 1 and 2, 30- and 90-day postoperative complications were limited to four and two men, respectively, all of whom had a grade 3 complication. At 6-month follow-up, 26/31 (84%) men reported their pain had resolved. There was one fistula recurrence managed with subsequent cystectomy. CONCLUSIONS: Complex anterior urinary fistulae to the pubic symphysis and thigh are devastating yet treatable conditions. Universally, these men have a history of radiotherapy and repeated endoscopic interventions. Surgical intervention with either cystectomy or primary repair was highly successful.

Health-Related Quality of Life and Sleep Disorders in Patients With a Urostomy: Is There a Relationship?

PURPOSE: The purpose of this study was to evaluate the relationship between health-related quality of life (HRQOL) and sleep disorders in persons living with a urostomy. DESIGN: A cross-sectional descriptive study. SUBJECTS AND SETTINGS: Eighty-six adults with a urostomy who were cared for in a stoma outpatient clinic of a hospital in Osaka, Japan, for at least 1 month before data collection, and who were attending support group meetings comprised the sample. The majority of participants (n= 68; 79.1%) were diagnosed with bladder cancer; the median time since ostomy surgery was 3.7 years. METHODS: Participants were queried about demographic and pertinent clinical data; they also completed 2 instruments that measured HRQOL and sleep quality. All data were collected via interview. HRQOL was assessed using a Japanese language version of the World Health Organization Quality of Life (WHOQOL). Sleep quality was evaluated using a Japanese language version of the Pittsburgh Sleep Quality Index (PSQI-J). Demographic and clinical data were collected via a questionnaire designed for this study. RESULTS: WHOQOL scores among persons living with a urostomy were significantly (P < .001) lower than scores among the general population in Japan. Forty-six participants (53.5%) had scores that were higher than 5.5, the cut-off point on the PSQI-J indicating reduced sleep quality. Scores on the PSQI-J were significantly negatively associated with the cumulative scores for WHOQOL scores (standardized partial regression coefficient -0.504, P < .001) even after adjustment based on all other variables. CONCLUSIONS: Study findings suggest that persons with a urostomy have lower HRQOL and sleep quality than adults in the general population.

Clinical and Economic Burden of Peristomal Skin Complications in Patients With Recent Ostomies.

PURPOSE: The purpose of this study was to estimate the risk and economic burden of peristomal skin complications (PSCs) in a large integrated healthcare system in the Midwestern United States. DESIGN: Retrospective cohort study. SUBJECTS AND SETTING: The sample comprised 128 patients; 40% (n = 51) underwent colostomy, 50% (n = 64) underwent ileostomy, and 10% (n = 13) underwent urostomy. Their average age was 60.6 ± 15.6 years at the time of ostomy surgery. METHODS: Using administrative data, we retrospectively identified all patients who underwent colostomy, ileostomy, or urostomy between January 1, 2008, and November 30, 2012. Trained medical abstractors then reviewed the clinical records of these persons to identify those with evidence of PSC within 90 days of ostomy surgery. We then examined levels of healthcare utilization and costs over a 120-day period, beginning with date of surgery, for patients with and without PSC, respectively. Our analyses were principally descriptive in nature. RESULTS: The study cohort comprised 128 patients who underwent ostomy surgery (colostomy, n = 51 [40%]; ileostomy, n = 64 [50%]; urostomy, n = 13 [10%]). Approximately one-third (36.7%) had evidence of a PSC in the 90-day period following surgery (urinary diversion, 7.7%; colostomy, 35.3%; ileostomy, 43.8%). The average time from surgery to PSC was 23.7 ± 20.5 days (mean ± SD). Patients with PSC had index admissions that averaged 21.5 days versus 13.9 days for those without these complications. Corresponding rates of hospital readmission within the 120-day period following surgery were 47% versus 33%, respectively. Total healthcare costs over 120 days were almost $80,000 higher for patients with PSCs. CONCLUSIONS: Approximately one-third of ostomy patients over a 5-year study period had evidence of PSCs within 90 days of surgery. Costs of care were substantially higher for patients with these complications.

Urinary diversions: A time to enrich surgical training?

OBJECTIVE: To assess the potential exposure to complex urologic procedures, specifically urinary diversion, during a gynecologic oncology fellowship. METHODS: We queried the University HealthSystem Consortium (UHC) database to determine the total number of urinary diversions performed from October 2008 to August 2012. This data was used to estimate the mean number of urinary diversions performed each year. Gender, primary diagnosis, type of diversion, gynecologic oncologist involvement, and medical center were explored. RESULTS: Of the nearly 21,000 urinary diversions performed in UHC participating hospitals during the study period, 6180 (29.5%) were performed in women. On average, 1648 urinary diversions are performed in women each year, with gynecologic malignancies accounting for 6.8% of cases. We estimate that a gynecologic oncologist was involved with 87 cases per year at nonprofit academic medical centers in the US. With approximately 112 clinically active fellows per year during the study period, this equates to less than one diversion per clinical fellow per year if cases are equally distributed among centers. However, the majority of urinary diversions with gynecologic oncologist involvement were performed at just a fraction of centers. Thus, only a small contingent of fellows may be getting the greatest exposure to urinary diversions. CONCLUSIONS: The majority of urinary diversions in women in the US are performed for bladder carcinoma by urologists. The estimated number of cases per clinical gynecologic oncology fellow per year is less than one. Strategies to improve fellow exposure to urinary diversion and consideration of alternative surgical training modalities should be explored.

Urinary diversion for patients with inoperable obstetric vesicovaginal fistula: the Jos, Nigeria experience.

INTRODUCTION: Repair of obstetric urinary fistula may result in successful fistula closure, but often incontinence persists. Our goal was to review our experience with continent urinary diversion in our patients with inoperable vesicovaginal fistula (VVF). METHODS: The database of patients who underwent urinary diversion at ECWA Evangel VVF Centre in Jos, Nigeria, between 1996 and 2012, was reviewed. Complications and surgical outcomes were noted. The earlier patients (1996-2002) and the later patients (2003-2012) were compared. RESULTS: Urinary diversions were performed on 118 patients. Compared with the earlier patients, the later patients more often underwent modified Mainz II diversions, had similar complication rates, but had better outcomes. The use of ureteric catheters intraoperatively and the performance of modified Mainz II pouch were associated with a better outcome. Overall perioperative mortality was 2.5 %. CONCLUSIONS: Urinary diversion is feasible in a low-resource setting. Use of modified Mainz II pouch diversion and intraoperative ureteric catheters were associated with a better outcome. Urinary diversion should be undertaken only after the careful counseling of each patient, and by an experienced surgeon.
