RESUMEN
OBJECTIVE: To evaluate whether performing preoperative urodynamic study influences postoperative urinary symptoms of women with stress urinary incontinence that underwent transobturator sling. METHODS: Retrospective analysis of patients treated for stress urinary incontinence by transobturator sling from August 2011 to October 2018. Predictor variables included preoperative urodynamic study, age, incontinence severity, body mass index, preoperative storage symptoms and previous anti-urinary incontinence procedure. Outcome variables were postoperative subjective continence status, storage symptoms and complications. Logistic regression after propensity score was employed to compare outcomes between patients who underwent or not pre-operative urodynamic study. RESULTS: The present study included 88 patients with an average follow-up of 269 days. Most patients (n = 52; 59.1%) described storage symptoms other than stress urinary incontinence, and 38 patients (43.2%) underwent preoperative urodynamic studies. Logistic regression after propensity score did not reveal an association between urinary continence outcomes and performance of preoperative urodynamic study (odds ratio 0.57; confidence interval [CI]: 0.11-2.49). Among women that did not undergo urodynamic study, there was a subjective improvement in urinary incontinence in 92% of the cases versus 87% in those that underwent urodynamic study (p = 0.461). Furthermore, postoperative storage symptoms were similar between women who did not undergo urodynamic study and those who underwent urodynamic study, 13.2% versus 18.4%, respectively (p = 0.753). CONCLUSION: Preoperative urodynamic study had no impact on urinary incontinence cure outcomes as well as on urinary storage symptoms after the transobturator sling in women with stress urinary incontinence.
OBJETIVO: Avaliar a influência do estudo urodinâmico pré-operatório nos resultados miccionais pós-operatórios em mulheres com incontinência urinária de esforço submetidas a sling transobturador. MéTODOS: Análise retrospectiva de mulheres com incontinência urinária de esforço submetidas a sling transobturador entre agosto de 2011 e outubro de 2018. As variáveis preditoras pré-operatórias, entre outras, foram a realização do estudo urodinâmico, gravidade da incontinência e sintomas urinários de armazenamento. As variáveis de desfecho pós-operatórias foram o status subjetivo da continência, sintomas de armazenamento urinário e complicações cirúrgicas. A regressão logística após o escore de propensão foi empregada para comparar os resultados entre os pacientes que foram submetidos ou não ao estudo urodinâmico pré-operatório. RESULTADOS: Foram incluídas no presente estudo 88 pacientes com um seguimento médio de 269 dias. A maioria das pacientes apresentava sintomas miccionais de armazenamento (n = 52; 59,1%) concomitantes à incontinência urinária de esforço. Um pouco menos da metade das pacientes (n = 38; 43,2%) foram submetidas a estudo urodinâmico pré-operatório. A regressão logística após o escore de propensão não revelou associação entre os resultados de continência urinária e a realização de estudo urodinâmico pré-operatório (odds ratio 0,57; intervalo de confiança [IC]: 0,112,49). Além disso, os sintomas de armazenamento urinário pós-operatórios foram similares entre as pacientes que não realizaram e aquelas que realizaram o estudo urodinâmico, 13,2% e 18,4% respectivamente (p = 0,753). CONCLUSãO: O estudo urodinâmico pré-operatório não teve impacto nos resultados de continência urinária, bem como nos sintomas de armazenamento urinário após o sling transobturatório.

PURPOSE: To analyze pre-transplantation and early postoperative factors affecting post-transplantation urine output and develop a predictive nomogram. PATIENTS AND METHODS: Retrospective analysis of non-preemptive first transplanted adult patients between 2001-2016. The outcomes were hourly diuresis in mL/Kg in the 1st (UO1) and 8th (UO8) postoperative days (POD). Predictors for both UO1 and UO8 were cold ischemia time (CIT), patient and donor age and sex, HLA I and II compatibility, pre-transplantation duration of renal replacement therapy (RRT), cause of ESRD (ESRD) and immunosuppressive regimen. UO8 predictors also included UO1, 1st/0th POD plasma creatinine concentration ratio (Cr1/0), and occurrence of acute cellular rejection (AR). Multivariable linear regression was employed to produce nomograms for UO1 and UO8. RESULTS: Four hundred and seventy-three patients were included, mostly deceased donor kidneys' recipients (361, 70.4%). CIT inversely correlated with UO1 and UO8 (Spearman's p=-0.43 and -0.37). CR1/0 inversely correlated with UO8 (p=-0.47). On multivariable analysis UO1 was mainly influenced by CIT, with additional influences of donor age and sex, HLA II matching and ESRD. UO1 was the strongest predictor of UO8, with significant influences of AR and ESRD. CONCLUSIONS: The predominant influence of CIT on UO1 rapidly wanes and is replaced by indicators of functional recovery (mainly UO1) and allograft's immunologic acceptance (AR absence). Mean absolute errors for nomograms were 0.08 mL/Kg h (UO1) and 0.05 mL/Kg h (UO8).
