Seguridad y eficacia de la uretroplastia según grupos etarios / Safety and efficacy of urethroplasty based on age groups

Objetivo: Analizar los resultados y las complicaciones posturetroplastia estratificando a los pacientes por edades. Como objetivo secundario, analizamos el impacto de la complejidad de la cirugía en cada grupo etario.Material y métodosSe trata de un estudio de cohortes, retrospectivo, donde se incluyó a todos los pacientes masculinos a quienes se les practicó uretroplastia entre enero de 2011 y diciembre de 2018. La información se obtuvo de la historia clínica electrónica. Los pacientes se agruparon en menores de 60 años, de 60 a 79 años y mayores de 80 años. Se evaluaron diferentes variables como antecedentes, comorbilidades, cirugías previas, complejidad de la cirugía. Se determinó la supervivencia libre de reestenosis y las complicaciones presentadas en cada grupo, según la clasificación de Clavien Dindo. Se utilizó el programa SPSS® para el análisis estadístico.ResultadosSe incluyeron un total de 783 pacientes. El seguimiento promedio fue de 19 meses. La sobrevida estimada a dos años libre de reestenosis en la población menor a 60, de 60 a 79 y mayor de 80 años fue de 87, 87 y 93,9% (IC 95%), respectivamente. En el análisis univariado, el grupo etario no fue una variable predictora de reestenosis. La realización de cirugía compleja es el único factor predictor de recidiva, aumentando el riesgo en un 60% (HR 1,64 IC 95% 1,05-2,56 p = 0,029). Se presentó una tasa general de complicaciones del 30,8%, siendo el 62% Clavien menor a dos. No encontramos asociación entre la frecuencia de las mismas y la edad. (AU)

Objective: To analyze the results and complications after urethroplasty based on patient age groups. As secondary objective, we analyzed the impact of operative complexity on each age group.Material and methodsThis is a retrospective cohort study that include male patients who underwent urethroplasty between January 2011 and December 2018. Data was obtained from the patients’ electronic health records. Patients were grouped as follows: < 60 years, 60-79 years and > 80 years. Variables evaluated were history, comorbidities, previous surgeries and operative complexity. Restenosis-free survival and complications presented in each group were determined according to the Clavien-Dindo classification system. The SPSS® program was used for statistical analysis.ResultsA total of 783 patients were included, and the mean follow-up was 19 months. The estimated 2-year restenosis-free survival in the population under 60, 60-79 and over 80 years was 87, 87 and 93.9% (IC 95%), respectively. Univariate analysis showed that the age group was not a predictor of restenosis. Complex surgery is the only predictor of recurrence, increasing the risk by 60% (HR 1.64, 95% CI 1.05-2.56, p = 0.029). There was an overall complication rate of 30.8%, and 62% of these were Clavien ≤ II. We found no association between the frequency of complications and age. (AU)

Safety and efficacy of urethroplasty based on age groups.

OBJECTIVE: To analyze the results and complications after urethroplasty based on patient age groups. As secondary objective, we analyzed the impact of operative complexity on each age group. MATERIAL AND METHODS: This is a retrospective cohort study that include male patients who underwent urethroplasty between January 2011 and December 2018. Data was obtained from the patients' electronic health records. Patients were grouped as follows: <60 years, 60-79 years and >80 years. Variables evaluated were history, comorbidities, previous surgeries and operative complexity. Restenosis-free survival and complications presented in each group were determined according to the Clavien-Dindo classification system. The SPSS® program was used for statistical analysis. RESULTS: A total of 783 patients were included, and the mean follow-up was 19 months. The estimated 2-year restenosis-free survival in the population under 60, 60-79 and over 80 years was 87, 87 and 93.9% (IC 95%), respectively. Univariate analysis showed that the age group was not a predictor of restenosis. Complex surgery is the only predictor of recurrence, increasing the risk by 60% (HR 1.64, 95% CI 1.05-2.56, p = 0.029). There was an overall complication rate of 30.8%, and 62% of these were Clavien ≤ II. We found no association between the frequency of complications and age. CONCLUSIONS: Urethroplasty is safe and effective regardless of age group. There are no statistically significant differences in outcomes and complications shown by the age group comparison. There were no significant differences when analyzing the impact of complex surgeries among the different age groups. The data indicate that age alone should not be taken as an absolute exclusion criterion for patients needing urethral reconstruction.

Postoperative urinary extravasation does not impact anterior urethroplasty surgical outcomes: a Latin American large cohort study.

OBJECTIVE: To determine the prevalence of postoperative urinary extravasation (POUE) following anterior urethroplasty, to analyze factors associated with its occurrence, and to study the impact of POUE on surgical success. MATERIALS AND METHODS: Retrospective cohort study including all male patients who have undergone a urethroplasty at our center between 2011 and 2018. Subjects with posterior location stricture, those who did not undergo routine radiographic follow-up, or patients with inadequate follow-up were excluded. Urinary extravasation was defined as presence of evident contrast extravasation on the postoperative voiding cystourethrogram (VCUG). Impact was determined as "need-for-reoperation". Uni- and multivariate analysis were performed to determine clinical and demographic variables associated with occurrence of extravasation and postoperative stricture. RESULTS: A total of 783 men underwent a urethroplasty and 630 fulfilled inclusion criteria. Urinary extravasation prevalence was 12.2%, and there was a "need-for-reoperation" in 1.1% of cases. On uni- and multivariate analysis, greatest stricture length (HR: 1.07 (1-1.2), p = 0.05) and penile urethral location (HR: 2.29 (1.1-4.6), p = 0.021) showed to be POUE predictors. POUE did not show to be a risk factor for postoperative stricture (HR: 1.57, 95% CI (0.8-3), p = 0.173). However, reoperation group  showed to be a risk factor (HR: 6.6, 95% CI 1.4-31, p = 0.019). CONCLUSIONS: Prevalence of POUE was 12.2%. Stricture length and penile urethral strictures were POUE predictors. POUE occurrence with successful conservative management did not appear to have impact on urethroplasty outcomes as it did not predict re-stricture. POUE was reoperation cause in 1.1% of total cases.
