RESUMEN
AIM: The aim of this study is to compare the improvements in irritative versus obstructive symptoms of the International Prostate Symptom Score (IPSS) after prostatic artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between 2010 and 2018, 186 patients underwent PAE in a single center and 174 patients were retrospectively selected. The inclusion criteria were symptoms due to BPH, refractory to pharmacological treatment and IPSS ≥ 8. The mean age of the patients was 63.7 ± 7.2 years, the mean prostate volume 89.5 ± 42.5 cm3, and the mean IPSS 19.0 ± 6.2 points. Patient data were reviewed at baseline, 3, 12 and 24 months and compared using the ANOVA mixed models and the Tukey's multiple comparison test. RESULTS: Obstructive subscores dropped more significantly than irritative subscores (p < 0.0001). The mean decrease in each IPSS item was frequency 2.4 (83%); urgency 0.8 (87%); nocturia 1.3 (49%); incomplete emptying 2.6 (83%); intermittency 2.3 (91%); weak stream 2.9 (82%); straining 1.6 (91%). The area under the curve for baseline obstructive scores was 0.7 (p = 0.006) and 0.59 (p = 0.182) for irritative scores. The most common BPH clinical manifestations include irritative and/or obstructive symptoms, the latter usually more prevalent. The IPSS drop observed after PAE suggests that it acts predominantly over obstructive symptoms (p < 0.0001). CONCLUSION: Although a predominant improvement in obstructive symptoms may be observed after PAE, nocturia complaints may require special attention. The severity of baseline obstructive symptoms may significantly predict clinical outcomes.

OBJETIVO: Determinar la calidad de vida asociada con la técnica quirúrgica en pacientes posoperados de plastia uretral. MÉTODO: Se estudiaron 29 pacientes intervenidos entre enero de 2011 y diciembre de 2015. Se aplicaron los cuestionarios Euroqol 5-D e International Prostate Symptom Score para medir calidad de vida y detectar recaídas, respectivamente. Se realizó estadística descriptiva, y se calcularon la incidencia acumulada, el riesgo relativo y la fracción atribuible. RESULTADOS: La incidencia de recaídas detectada por el International Prostate Symptom Score fue del 69% (p = 0.011); el riesgo relativo fue de 2.19 (intervalo de confianza del 95%: 2.092-2.288). La fracción atribuible a la exposición fue del 54%. La calidad de vida se asoció con la longitud de la lesión (p = 0.046), los síntomas urinarios bajos (p = 0.004) y la percepción individual del estado de salud (p = 0.003). La localización de la lesión se asoció con recaída (p = 0.008). La calidad de vida no se asoció con el tipo de plastia (p > 0.05). CONCLUSIONES: La incidencia de recurrencia posquirúrgica es alta. La calidad de vida es independiente de la técnica quirúrgica, pero está asociada con la longitud de la lesión y con los síntomas urinarios. OBJECTIVE: To determine the quality of life associated with the surgical technique in postoperative patients with urethral plasty. METHODS: 29 patients operated between January-2011 and December-2015 were studied. The questionnaires Euroqol 5-D and International Prostate Symptom Score were applied to measure quality of life and detect relapses, respectively. Descriptive statistics was performed, cumulative incidence, relative risk and attributable fraction were calculated. RESULTS: the incidence of relapse detected by the International Prostate Symptom Score was 69% (p = 0.011); the relative risk was 2.19 (95% confidence interval: 2.092-2.288). The fraction attributable to the exposure was 54%. The quality of life was associated with the length of the lesion (p = 0.046), low urinary symptoms (p = 0.004) and the individual perception of the state of health (p = 0.003). The location of the lesion was associated with relapse (p = 0.008). Quality of life was not associated with type of plasty (p > 0.05). CONCLUSIONS: The incidence of postoperative recurrence is high. The quality of life is independent of the surgical technique, but it is associated with the length of the lesion and urinary symptoms.

PURPOSE: We report three cases of spontaneous prostatic tissue elimination through the urethra while voiding following technically successful prostatic artery embolization (PAE) as a treatment for lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH). METHODS: All patients were embolized with 100- to 300-µm microspheres alone or in combination with 300- to 500-µm microspheres. RESULTS: During follow-up prior to eliminating the tissue fragments, the three patients all presented with intermittent periods of LUTS improvement and aggravation. After expelling the prostatic tissue between 1 and 5 months of follow-up, significant improvements in LUTS and urodynamic parameters were observed in all patients. CONCLUSIONS: Urethral obstruction after PAE caused by sloughing prostate tissue is a potential complication of the procedure and should be considered in patients with recurrent LUTS in order to avoid inappropriate management.

PURPOSE: To compare recurrence of lower urinary tract symptoms (LUTS) recurrence at 12 months following original prostate artery embolization (oPAE) or "proximal embolization first, then embolize distal" (PErFecTED) PAE for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: 105 consecutive patients older than 45 years, with prostate size greater than 30 cm3, International Prostate Symptom Score (IPSS) ≥ 8, quality of life (QoL) index ≥ 3, and refractory status or intolerance of medical management were prospectively enrolled between June 2008 and August 2013. The study was IRB-approved, and all patients provided informed consent. Patients underwent oPAE or PErFecTED PAE and were followed for at least 12 months. Technical success was defined as bilateral embolization and clinical success (non-recurrence) was defined as removal of the Foley catheter in patients with urinary retention, IPSS < 8 and QoL index < 3 at 12 months of follow-up. Nonparametric statistics were used to compare the study groups due to the size of the study population and distributions of clinical data. RESULTS: 97 patients had 12-month data and were categorized as oPAE without recurrence (n = 46), oPAE with recurrence (n = 13), PErFecTED without recurrence (n = 36), or PErFecTED with recurrence (n = 2). Recurrence was significantly more common in oPAE patients (χ 2, p = 0.026). Unilateral embolization was significantly associated with recurrence among patients who underwent oPAE (χ 2, p = 0.032). CONCLUSIONS: Both oPAE and PErFecTED PAE are safe and effective methods for treatment of LUTS, but PErFecTED PAE is associated with a significantly lower rate of symptom recurrence.
