Urodynamic Assessment of Neuronal Intranuclear Inclusion Disease.

Neuronal intranuclear inclusion disease (NIID) is a disease that causes leukoencephalopathy (dementia) and peripheral neuropathy (variable manifestation including bladder dysfunction). This is the first urodynamic report to show that bladder dysfunction in NIID is a combination of detrusor overactivity, decreased bladder sensation, large post-void residual, and neurogenic changes in the sphincter electromyogram. This report will help managing bladder dysfunction in NIID.

Urological implications of SARS CoV-19.

INTRODUCTION: The novel coronavirus disease 2019 (COVID-19), pandemic has afflicted > 3.3 million people around the world since December 2019. Though, more than 1000 publications have appeared in scientific journals addressing a plethora of questions, there is a considerable hiatus in understanding of the behavior and natural history of the virus and its impact on urology. Also, a modified approach is the need of hour in taking care of patients as urologists should safeguard their teams, families, and patients. MATERIAL AND METHODS: The authors have used guidelines from USA, Canada, UK, Europe and India for making recommendations to help urologist define their own policies that may have to be fine-tuned on the basis of continued and evolving challenges they would encounter and the local resources at their disposal. RESULTS: COVID-19 do effect genitourinary system from kidney to testis. The authors provide scientific basis to urologists to help identify patients by remote consultation who are likely to be harmed by coming to the hospital, and not to miss those who need hospitalization for diagnostic or therapeutic interventions. There is uncompromised need of specific precautions during surgery to safe guard the surgeon and his team along with the patient. CONCLUSIONS: Urological operations during COVID-19 pandemic should be limited to emergency cases during the acute phase with an exit strategy planned in a staggered manner, based on the scientific risk stratification. Telemedicine (e-clinics or virtual clinics) would help achieve the goal of risk stratification.

Costing Urologic Complications Following Pelvic Radiation Therapy.

OBJECTIVES: To describe patients presenting with urologic complications following pelvic radiation therapy and estimate the financial costs incurred in their treatment. PATIENTS AND METHODS: In the year ending June 2018, all urology admissions at Royal Newcastle Centre were reviewed for diagnostic codes pertaining to urethral or ureteric strictures, cystitis, and haematuria. Presentations were complications following radiotherapy if a diagnosis of radiation cystitis or stricture was recorded, and there was relevant prior radiotherapy. The Independent Hospital Pricing Authority's National Weighted Activity Unit (NWAU) 2018 calculators, admission data and the National Efficient Price were used to estimate costs of care. HNELHD HREC granted ethics approval (AU201808-10). RESULTS: Complications following radiotherapy accounted for 65 admissions in 53 discrete patients, accounting for 206 bed days and 3.7% of the 1748 total urology admissions in 1 year. The majority (86%) of admissions had at least 1 operation. Mean time since radiotherapy was 7 years (range 1-30). Mean number of operations related to complications following radiotherapy was 3 (range 0-11). Readmissions were more frequent (mean 1.9 admissions/year) than other urology inpatients (mean 1.3 admissions/year, P < .001). Mean NWAU18 value was 4.12 (range 2-8.3). Admission and procedure costs were AUD $1,346,700, secondary malignancies were $9,000 and emergency department costs were $45,864 for a combined total of $1,401,591. CONCLUSION: Patients requiring urological admission with complications following radiotherapy use more resources, stay for longer, have more operations and return more frequently than other urology patients. Conservative estimates of cost $25,900 per patient in the study year alone.

Longitudinal Comparison of Patient-Level Outcomes and Costs Across Prostate Cancer Treatments With Urinary Problems.

Prostate cancer (PCa) is the leading cancer in men in the United States. This study evaluated direct costs of treating urinary problems after PCa treatments and determined predictors of long-term costs for urinary problems. Data from the Cancer of Prostate Strategic Urologic Research Endeavor registry was analyzed for this study. Annual treatment costs for urinary problems for up to 14 years were compared among different primary PCa treatments, which included radical prostatectomy, external beam radiation therapy, brachytherapy, and watchful waiting. A multivariate generalized estimating equation (GEE) model with bootstrapping was estimated to identify the predictors associated with treatment costs for urinary problems. A total of 3,062 eligible patients were identified with a mean age of 65 years at diagnosis. Mean annual treatment cost for urinary problems across all patients with PCa was $118/patient. Those greater than 74 years old had the highest cost ($238/patient). Mean annual cost for urinary problems among only those with urinary problems was $432. Multivariate regression showed patients undergoing radical prostatectomy had significantly lower (-63%, p = .01) costs for urinary problems than those treated with watchful waiting. This study helps to understand the importance of treating urinary problems associated with different PCa treatments and highlights their medical care costs. The pattern of treatment costs for urinary problems across all PCa treatments suggests that clinicians need to offer treatment for urinary problems to all PCa patients over longer time periods, even to those choosing watchful waiting.

Concentration of Costs Among High Utilizers of Health Care Services Over the First 10 Years After Spinal Cord Injury Rehabilitation: A Population-based Study.

OBJECTIVE: The purpose of this study was to (1) categorize individuals into high, medium, and low utilizers of health care services over a 10-year period after the onset of spinal cord injury (SCI) and (2) identify the pattern of causes of hospitalizations and the characteristics associated with high utilization. DESIGN: Retrospective analysis of self-report assessment linked to administrative data. SETTING: Data were collected from participants living in and utilizing hospitals in the state of South Carolina. PARTICIPANTS: Adult participants with traumatic SCI were identified through a state SCI Surveillance System Registry, a population-based system capturing all incident cases treated in nonfederal facilities. Among 963 participants who completed self-report assessments, we matched those with a minimum of 10 years of administrative records for a final sample of 303 participants (N=303). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Costs related to health care utilization for emergency department visits and hospitalizations, as measured operationally by hospital charges at full and established rates; causes of hospitalizations RESULTS: Over two-thirds of the total $49.4 million in charges for hospitalization over the 10-year timeframe (69%) occurred among 16.5% of the cohort (high utilizers), whereas those in the low utilizer group comprised 53% of the cohort with only 3.5% of the charges. The primary diagnoses were septicemia (50%), other urinary tract disorder (48%), mechanical complication of device, implant, or graft (48%), and chronic ulcer of skin (40%). Primary diagnoses were frequently accompanied by secondary diagnoses, indicating the co-occurrence of multiple secondary health conditions. High utilizers were more likely to be male, minority, have a severe SCI, have reported frequent pressure ulcers and have income of less than $35,000 per year. CONCLUSIONS: The high cost of chronic health care utilization over a 10-year timeframe was concentrated in a relatively small portion of the SCI population who have survived more than a decade after SCI onset.

Urological dysfunctions in patients with Parkinson's disease: clues from clinical and non-invasive urological assessment.

BACKGROUND: Autonomic nervous system dysfunction, common in patients with Parkinson's disease (PD), causes significant morbidity and it is correlated with poor quality of life. To assess frequency of urinary symptoms in patients with PD, without conditions known to interfere with urinary function. METHODS: Non-demented PD patients were consecutively enrolled from the outpatients clinic of our department. Scales investigating motor and non-motor symptoms were carried out. Evaluation of urinary dysfunctions was carried out using the AUTonomic Scale for Outcomes in Parkinson's disease (SCOPA-AUT) questionnaire. Patients underwent noninvasive urological studies (nUS), including uroflowmetry and ultrasound of the urinary tract. RESULTS: Forty-eight (20 women, 42%) out of 187 PD patients met the inclusion criteria and were enrolled in the study. Mean SCOPA-AUT score was 14.1 ± 6.9 (urinary symptoms subscore 5.2 ± 3.8). Among those evaluated by the SCOPA-AUT scale, the urinary symptoms were among the most common complaints (93.8%). At nUS mean maximum flow rate (Qmax) was 17.9 ± 9.1 ml/s, and mean postvoid residual (PVR) urine volume was 24.4 ± 44.1 ml. Ultrasound investigation documented prostate hypertrophy in 12 male patients (42.8%). Urinary items of the SCOPA-AUT (SCOPA-U subscore) correlated with measures of disease severity only in female patients. CONCLUSION: Urinary symptoms and abnormal findings in nUS are common in PD. Though nigrostriatal degeneration might be responsible for urinary symptoms also in the early-intermediate stage of the disease, when urinary dysfunction occurs other medical conditions need to be excluded.

Patient-reported health-related quality of life for men treated with low-dose-rate prostate brachytherapy as monotherapy with 125-iodine, 103-palladium, or 131-cesium: Results of a prospective phase II study.

PURPOSE: To compare quality of life (QoL) after brachytherapy with one of the three approved radioactive isotopes. METHODS AND MATERIALS: Patients with mostly favorable intermediate-risk prostate cancer were treated on this prospective phase II trial with brachytherapy as monotherapy, without hormonal therapy. QoL was recorded at baseline and each follow-up by using the Expanded Prostate Cancer Index Composite instrument. The minimal clinically important difference was defined as half the standard deviation of the baseline score for each domain. Mixed effect models were used to compare the different isotopes, and time-driven activity-based costing was used to compute costs. RESULTS: From 2006 to 2013, 300 patients were treated with iodine-125 (I-125, n = 98, prescribed dose [PD] = 145 Gy), palladium-103 (Pd-103, n = 102, PD = 125 Gy), or cesium-131 (Cs-131, n = 100, PD = 115 Gy). Median age was 64.9 years. Median follow-up time was 5.1 years for the entire cohort, and 7.1, 4.8 and 3.3 years for I-125, Pd-103, and Cs-131 groups, respectively. All three isotope groups showed an initial drop in QoL at first follow-up, which gradually improved over the first 2 years for urinary and bowel domains. QoL profiles were similar between I-125 and Pd-103, whereas Cs-131 showed a statistically significant decrease in QoL regarding bowel and sexual function at 12 months compared with Pd-103. However, these differences did not reach the minimal clinically important difference. Compared with I-125, the use of Pd-103 or Cs-131 resulted in cost increases of 18% and 34% respectively. CONCLUSIONS: The three different isotopes produced a similar QoL profile. Statistically significant differences favored Pd-103/I-125 over Cs-131 for bowel and sexual QoL, but this did not reach clinical significance.

Inverse probability of treatment-weighted competing risks analysis: an application on long-term risk of urinary adverse events after prostate cancer treatments.

BACKGROUND: To illustrate the 10-year risks of urinary adverse events (UAEs) among men diagnosed with prostate cancer and treated with different types of therapy, accounting for the competing risk of death. METHODS: Prostate cancer is the second most common malignancy among adult males in the United States. Few studies have reported the long-term post-treatment risk of UAEs and those that have, have not appropriately accounted for competing deaths. This paper conducts an inverse probability of treatment (IPT) weighted competing risks analysis to estimate the effects of different prostate cancer treatments on the risk of UAE, using a matched-cohort of prostate cancer/non-cancer control patients from the Surveillance, Epidemiology and End Results (SEER) Medicare database. RESULTS: Study dataset included men age 66 years or older that are 83% white and had a median follow-up time of 4.14 years. Patients that underwent combination radical prostatectomy and external beam radiotherapy experienced the highest risk of UAE (IPT-weighted competing risks: HR 3.65 with 95% CI (3.28, 4.07); 10-yr. cumulative incidence = 36.5%). CONCLUSIONS: Findings suggest that IPT-weighted competing risks analysis provides an accurate estimator of the cumulative incidence of UAE taking into account the competing deaths as well as measured confounding bias.

Preoperative assessment of the ureter with dual-phase contrast-enhanced computed tomography for lateral lumbar interbody fusion procedures.

BACKGROUND: Performing the minimally invasive lateral lumbar interbody fusion (LIF), such as the extreme lateral interbody fusion (XLIF) and oblique lateral interbody fusion (OLIF), through a retroperitoneal approach has become increasingly popular. Although urological injury is a major complication of LIF, the anatomical location of the ureter and its risk of injury have not been assessed. The purpose of this study was to evaluate the efficacy of dual-phase contrast-enhanced computed tomography for assessing the location of the ureter and risk of its injury in consecutive LIF cases. METHODS: 27 cases (12 men and 15 women) were enrolled in the study. Dual-phase contrast-enhanced CT was performed preoperatively, and the risk of ureteral injury was assessed. The location of the ureter was classified using the psoas muscle and vertebral body as reference structures for OLIF and XLIF procedures, respectively. During the OLIF procedures, the location of the ureter was additionally assessed with direct vision and manual palpation in all cases. Simultaneously, potential vascular anomalies were assessed with both 3D and axial images of CT. RESULTS: A total of 125 among 162 ureters, excluding 13 with insufficient enhancement and 24 (44.4%) within the kidney at the L2-L3 level, were assessed preoperatively; 113 ureters (90.4%) were classified as anatomically close to the surgical corridor for OLIF, and 20 ureters (16.0%) as having a potential risk of injury during XLIF. In one case, OLIF was converted to a conventional posterior procedure because of a vascular anomaly. Intraoperative findings showed that ureters moved anteriorly with the peritoneum in all cases, as assessed by manual palpation under direct vision. CONCLUSIONS: Dual-phase contrast-enhanced CT is useful in assessing the location of the ureter, kidney, and vascular structures simultaneously. Both OLIF and XLIF have a potential risk of urological injury.

Association between age, breed and sex in relation to urinary disorders in insured cats in Japan during fiscal year 2012.

Data from 48,187 cats insured between April 2012 and March 2013 were analyzed using logistic regression analysis to determine the association of age, breed and sex with the occurrence of urinary disorders. The overall annual prevalence of urinary disorders was 12.2%. Using crossbreeds as the reference breed, Abyssinian cats had the highest odds of having urinary disorders with a ratio of 1.40 (95% confidence interval: 1.20-1.63), followed by Norwegian Forest Cats and Somalis. Male cats had higher odds of having urinary disorders with a ratio of 1.27 (1.20-1.35) over female cats. Older cats had higher odds of having urinary disorders than young cats.

Medical and psychosocial problems in middle-aged spina bifida patients: survey among members of the Dutch patients' association.

PURPOSE: To identify physical, emotional and psychosocial issues in the older person with spina bifida (SB). METHOD: Members of the Dutch patients' association aged >25 years (n = 184) were asked to complete a questionnaire. This survey contained questions on physical and psychosocial complaints, as well as problems regarding social participation. RESULTS: A total of 61 people (33.2%) with a median age of 45 years (IQR 33.5-60.0) years responded. During the previous 5 years, 86.9% experienced new physical complaints, whereas only 13.1% remained free of new complaints. 50.8% of the persons had new bladder problems and 44.1% had bowel complaints. Older persons more often had physical complaints. New musculoskeletal problems occurred in 75.4%. Psychological problems were common (78.7%). Overall psychological problems were not associated with gender, hydrocephalus or age. Social participation was good, with 90.2% of persons taking part in some type of social activity. CONCLUSIONS: In this study, a majority of adult persons with SB reported newly arising physical and psychological problems during the previous 5 years. Given the large number and diversity of the newly emerging problems after adolescence, regular and multidisciplinary surveillance of adult persons with SB is recommended. IMPLICATIONS FOR REHABILITATION: Adults with spina bifida often disappear from follow-up, or are forced to take care of their follow-up themselves. According to a survey carried out among adult SB-patients from the general community, these persons continued to struggle with many physical and psychosocial problems. Given the high number of psychosocial problems in this sample of patients, psychosocial counseling could be beneficial during follow-up. This paper adds to the body of evidence indicating that multidisciplinary follow-up for SB-patients could be beneficial, also when patients grow beyond the age of 18 years.

The diagnosis and management of lower urinary tract symptoms in multiple sclerosis patients.

Sixty-five percent of multiple sclerosis patients have moderate to severe urinary symptoms and up to 14% initially present with urinary symptomatology. Urinary retention, neurogenic detrusor overactivity, and detrusor sphincter dyssynergia, all increase the risk for urinary tract infections in patients with multiple sclerosis, and these infections may exacerbate their immune response, leading to symptom progression. Fewer than half of the patients with urinary symptoms have seen a specialist and only half have been treated for their neurogenic detrusor overactivity. Several treatments including pelvic floor muscle therapy, pelvic floor electrical stimulation, anticholinergics, desmopressin, sacral nerve neuromodulation, posterior tibial nerve stimulation, cannabinoids, and intravesical therapy with vanniloids, as well as botulinum toxin, have all been shown to be effective in treating urinary symptoms in those with multiple sclerosis. Clean intermittent catheterization is invaluable in patients with persistent urinary retention to avoid infection and upper tract dysfunction. Indwelling transurethral catheterization should be avoided because of the high risk of infection. Identification and successful treatment of these urinary conditions will improve the health and quality of life for these men and women.

Importancia epidemiológica, asistencial y económica del cultivo de orina, en pacientes hospitalizados y de la comunidad / Epidemiological, economical and assistance importance of urine culture on in-patients and out-patients. Hermanos Ameijeira Hospital

Introducción: una de las infecciones más comunes que afectan al ser humano a lo largo de su vida y una de las más frecuentes tanto en el ámbito comunitario como en el nosocomial, son las infecciones del tracto urinario (ITU). Es conocido que los agentes etiológicos se relacionan fundamentalmente con bacilos gramnegativos, pero en la mayoría de los casos, sobre todo en los ambulatorios, no se realiza el cultivo de las muestras de orina antes de iniciar del tratamiento antibacteriano. Al mismo tiempo, una terapia inicial correctamente indicada, tomando como base los datos aportados por el Laboratorio de Microbiología, puede significar evolución favorable y menores costos en sentido general. Objetivos: determinar los principales agentes etiológicos con sus patrones de sensibilidad antimicrobiana, en ITU hospitalarias y de la comunidad, asi como evaluar los costos relacionados con los cultivos microbiológicos, según el tipo de resultado alcanzado. ..

Introduction: the high incidence and prevalence of urinary tract infections in both hospital patients and outpatients determine that the exact knowledge of the major etiologic agents with antimicrobial susceptibility patterns gain immeasurable epidemiological and economic assistance values. Objective: to do Microbial map for hospital patients, and outpatients suffering from UTIs. Methods: a retrospective and cross study was conducted in 13,939 urine cultures from inpatient and outpatients received in the Microbiology Laboratory at Hermanos Ameijeiras hospital from September 2009 to August 2010. Results: 62 percent of the samples were negative, 22 percent positive, and 16 percent were reported as the contaminated samples representing a cost of 86 100, 61 980, and 22 300 CUC, respectively, with an overall total of 170 380 CUC. The microorganism most frequently isolated was Escherichia coli in both groups (76.4 percent and 54.0 percent respectively), which were higher than 55 percent to trimethoprim/sulfamethoxazole and ciprofloxacin. Ampicillin resistance was close to 90 percent for almost all microorganisms. Nitrofurantoin for Escherichia coli presented the lowest percentages of resistance. Antimicrobial resistance was higher in hospital patients. Conclusions: the monetary cost per patient for a second or third course of antibiotics, in an initial incorrect therapy, may imply spending approximately 100 times more than a correct initial therapy based on scientific evidence

Analysis of functional status, quality of life and community integration in earthquake survivors with spinal cord injury at hospital discharge and one-year follow-up in the community.

OBJECTIVE: This study compares functional status, quality of life and community integration in 2008 Sichuan earthquake survivors with spinal cord injury at hospital discharge and at 1-year follow-up in the community. METHODS: Twenty-six subjects with spinal cord injury completed demographic and medical questionnaires and underwent medical examination at discharge from a hospital rehabilitation department and after 1 year in the community. Functional status, quality of life and community integration were assessed by appropriate instruments over this period. RESULTS: Functional status measures showed significantly increased (p < 0.05) scores for the Modified Barthel Index and Walking Index for Spinal Cord Injury II; depression and pain scores were reduced with no statistical significance. After discharge, nearly half of patients developed a new pressure sore and most patients had urinary complications. Self-reported quality of life, overall health, and satisfaction with social relationships increased significantly (p < 0.05), while the environment domain was reduced (p < 0.05). Social participation (i.e. community integration) results showed an improvement in physical independence and mobility (p < 0.05), but a decline in cognitive independence (p < 0.05). Only 15% of the population returned to work. CONCLUSION: Special attention should be paid to cognitive and emotional function, occupational training and social integration during rehabilitation measures after earthquakes.

Hospitalization costs of open vs. laparoscopic appendectomy: 5-year experience.

BACKGROUND: There is an ongoing debate over certain aspects of laparoscopic appendectomy (LA) over open appendectomy (OA) in regard to hospitalization costs and associated complications. METHODS: A database was used to obtain the charts for either LA or OA performed during a 5-year period. Variables analyzed were age, gender, hospitalization cost, length of stay and complications. RESULTS: Of 1792 appendectomies performed, 633 (35.3%) were OA and 1159 (64.6%) were LA. Both groups were statistically similar with regard to gender (p = 0.075) but differed with respect to age, demonstrating an older patient population in the LA group (p <0.0001). Length of stay was significantly higher in the OA group (3.33 vs. 2.52) days, p <0.0001). The overall hospitalization cost of LA was 25% higher than the OA cost (p = 0.0005). The cost of an uncomplicated LA case was 1.7 times higher than in the OA group (p ≤ 0.0001). We found no statistically significant differences between the hospitalization cost of an OA and LA group when both procedures were associated with a complication (p = 0.5319). A higher complication rate was observed in the OA group, 60 cases (9.47%) as compared to the LA group, 46 cases (3.96%), p <0.0001. The increased rate of complications observed was related to cardiovascular, wound and infectious problems. CONCLUSIONS: Noncomplicated LA was associated with a higher hospitalization cost. There was no difference with regard to complicated cases. The incidence of complications increased in the OA group.

Obesity--America's health crisis.

Obesity has been associated with a 36% increase in health care spending, and treating the obese patient can be medically challenging. This article provides a brief overview of treating patients who are obese or overweight, and how urologic nurses can educate their patients and others on treatment options. The impact of healthy diet and exercise, as well as considering overweight individuals without bias or prejudice, are discussed.

A prospective study on the association between lower urinary tract symptoms (LUTS) and erectile dysfunction: results from a large study in elderly Chinese in Southern China.

INTRODUCTION: Although many cross-sectional studies have been conducted on the association between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), no studies were prospective in Asia. Aim. The relationship between LUTS and ED is examined using a prospective cohort of 2000 Chinese men. METHODS: Baseline and 4-year data from a large prospective cohort study of 2000 Chinese elderly men were analyzed. A total of 1,736 subjects were included in the current analysis after excluding those with history of bladder or prostate cancer, or urological surgery, and those who used alpha blockers or anti-androgen. MAIN OUTCOME MEASURES: LUTS were measured at baseline by the International Prostatic Symptom Score and ED was measured using one question on impotence at the end of 4 years. RESULTS: A dose-response relationship was observed for the relationship between baseline severity of LUTS and severity of ED at follow-up with those who had more severe LUTS at baseline with an increased odds of having more severe ED (odd ratio [OR] = 1.86, confidence interval [CI]: 1.16-2.97 for mild LUTS at baseline; OR = 2.95, CI: 1.81-4.81 for moderate LUTS at baseline; and OR = 3.82, CI: 2.00-7.27 for severe LUTS at baseline). Other baseline factors that were statistically significantly associated with ED included body mass index (OR = 1.13, CI: 1.01-1.26), hypertension (OR = 1.30, CI: 1.02-1.65) and diabetes (OR = 1.44, CI: 1.07-1.93). CONCLUSION: The presence of LUTS is associated with ED with more severe LUTS being associated with higher degree of ED in men.

Urological management of the patient with traumatic spinal cord injury.

Traumatic spinal cord injury is a very comprehensive subject, debated in many scientific papers. It interests various medical specialties, but also other sciences, like economy, psychology or social science. The patient having a motoric disability, with sphincter troubles and other associated pathologies secondary to a traumatic lesion of the spinal cord, represented a social problem from the antiquity. The first centers dedicated exclusively to these patients were established during Napoleon. Nevertheless, a systematic approach to these patients was not possible before the end of the Second World War, when scientific and economic development made possible the establishment of medical facilities specialized in the complex evaluation and treatment of patients with spinal cord injury (SCI). Between the two world wars, physicians were concentrating their efforts to keep these patients alive, considering that the main target was to treat or prevent complications which could be fatal to the patient. The first scientific papers underlining the essential place of lower urinary tract disorders in the vital prognostic of the SCI patient are dating back to this time. In modern times, the target for every patient with SCI should be social reinsertion and obtaining as much autonomy as possible. The physician needs to tune up his treatment according to this factor. The continuous evolution of medicine, alongside with technical progress and the development of modern social security have created the premises for a real quality of life of the paraplegic or even quadriplegic patient. The lower urinary tract becomes not only a key for prolonged survival, but also one of the most important elements for social reinsertion.

Early urologic complications after pediatric renal transplant: a single-center experience.

BACKGROUND: Urologic complications cause substantial morbidity in the pediatric population after renal transplantation, but their impact on graft survival and transplant costs is poorly understood. In this retrospective review, we evaluated the records of all pediatric renal transplant recipients at our center from 1995 to 2004. METHODS: Patient demographics, presence of urinary leak, stricture, compression, or vesicoureteral reflux, and hospital costs were analyzed. Univariable analysis identified predictors of complications and of need for reoperation, and Kaplan-Meier analysis was used to assess graft survival in relation to urinary complications. RESULTS: One hundred forty-seven children received renal transplants; mean follow-up was 1478+/-965 days. Nine (6.1%) patients had urologic complications and seven (4.8%) patients developed vesicoureteral reflux requiring reoperation. Sex, ischemia time, race, previous transplant, donor type, nephrectomy technique, and stent use did not affect the incidence of urologic complications. Previous urologic reconstruction and pretransplant ureteral pathologic conditions increased the risk of urologic complication and vesicoureteral reflux. Patients with urologic complications had equivalent graft survival, but triple the hospital costs of unaffected recipients. CONCLUSIONS: Prior urologic surgery is associated with increased risk of urologic complications posttransplant. Posttransplant urologic complications are associated with substantially increased costs in the first year after transplant, but not with decreased graft survival.
