Holmium laser enucleation of the prostate (HoLEP) in short-circuit outpatient care: Is prostatic volume a limiting factor?

INTRODUCTION AND OBJECTIVES: Our goals were to study prostatic volume as a limiting factor after HoLEP surgery with short-circuit outpatient care (4 h) and to define other factors that affect the success of the proposed circuit. MATERIALS AND METHODS: An observational analysis and review was performed using a prospective database. Preoperative, intraoperative, and postoperative variables were included for patients who were scheduled for short-circuit outpatient care (SCOC) and who underwent HoLEP between 2020 and 2023. We defined SCOC as a postoperative hospital stay of 4 h. Subjects who required more than 4 h in hospital were categorized as conventional hospital admission (CHA). A descriptive populational study was conducted, expressing the mean using a 95% confidence interval and percentages for the continuous variables. In order to analyze them, we used the Student's t-test for the continuous variables and the chi-squared test for the categorical variables. RESULTS: Sixty-eight patients were included, 54 of which completed SCOC, which represented a success ratio of 79.5%. The mean age and prostatic volume of the whole cohort were 68.9 (±6.8) years and 79.5 (±29.1) mL, respectively. We found no significant differences in age, prostatic volume, antiplatelet drug use, indwelling bladder catheter, or applied energy among the subjects who completed SCOC and those who required CHA. No patient was presented with a complication of Grade 3 (or higher) in the modified Clavien-Dindo classification. At the six-month follow-up, no differences were observed in the uroflowmetry or International Prostate Symptoms Score variables. CONCLUSIONS: Prostatic volume does not seem to be a limiting factor after undergoing HoLEP with short-circuit outpatient care.

Predictive factors of post-HoLEP incontinence: differences between stress and urgency urinary incontinence.

INTRODUCTION: The analysis of post-HoLEP urinary incontinence (UI) has traditionally focused on stress UI. Our aim is to evaluate the factors associated with stress and urgency UI in the first month after the surgery. METHODS: Data were obtained from patients who underwent HoLEP by the same experienced surgeon. UI was evaluated at one month and at 6 months after the surgery. Three groups were defined: continent patients, patients with pure urgency UI and patients with stress or mixed UI. Preoperative, intraoperative, urodynamic and clinical variables were analyzed and compared between the three groups. RESULTS: In total, 235 subjects were included. One month after the surgery, 156 (66.5%) were continent (group 1), 49 (20.8%) reported pure urgency UI (group 2), and 30 (12.7%) reported some level of stress UI (group 3). In Group 2, the factors associated with urgency UI in the univariate analysis were age, presurgical urgency UI, having diabetes or hypertension. In Group 3, age, prostatic volume, preoperative PSA, time of enucleation, weight of the resection in grams, having an IDC or being diabetic were significant in the univariate analysis. In the multivariate analysis, age predicts both types of UI, while prostatic volume and having an IDC predict stress or mixed UI. CONCLUSION: In the first month post-HoLEP, age is a predictive factor of urgency UI and stress UI. In addition, prostatic volume and the presence of an indwelling urinary catheter are predictive factors of stress UI.

The Cancer of the Bladder Risk Assessment (COBRA) score accurately predicts cancer-specific survival after radical cystectomy: external validation and lymphovascular invasion assessment value to improve its performance.

The Cancer of the Bladder Risk Assessment (COBRA) score is a predictive tool for estimating Cancer Specific Survival (CSS) after Radical Cystectomy (RC) for urothelial carcinoma. COBRA score variables are: age at RC, Tumor stage and Lymph Node Density (LND). We sought to externally validate the COBRA score and to improve its performance in estimating CSS adding Lymphovascular Invasion (LVI) as a further variable (Modified COBRA score). Clinicopathological and survival data from 789 patients who underwent RC and Pelvic Lymph Node Dissection (PLND) between January 2007 and December 2020 in two European referral centers (Paris, France and Badalona, Spain) were analyzed. COBRA score was applied to our cohort and CSS Kaplan-Meier curves were performed. Univariable and Multivariable analysis was performed in order to identify risk factors for Cancer Specific Mortality (CSM) and a score was assigned for any statistically significant risk factor; afterward, c-index calculation was performed and CCS curves have been plotted for the model after having integrated LVI variable to the COBRA score. Finally, we compared both COBRA score and Modified COBRA score models with the established AJCC model. A total of 789 patients underwent RC during the observation period. Complete data were available for 731 patients with a median follow-up of 32 months (8-47). CSM was 27.6% (no. 218 patients) at follow-up. When COBRA score was applied to our cohort, c-index was 0.76. Regression COX analysis has shown HR 0.36, CI 95% (0.16-0.83), P = .016 for patients with COBRA score 1; HR 0, CI 95% (0-1.77), P =.94 for score 2; HR 0.51, CI 95% (0.39 -0.67), P =.001 for score 3; HR 1.67, CI 95% (1.23-2.27), P =.001 for score 4; HR 2.45, CI 95% (1.51-3.99), P =.001 for score 5; HR 2.01, CI 95% (1.42-2.85), P =.001 for score 6 and HR 0.66, CI 95% (0.09-4.73), P =.682 for score 7. When the LVI variable was added to the CSS predictive model the discriminatory power increased to a c-index of 0.78. COBRA score adequately identifies those patients with a higher risk of CSM, with a c-index of 0.76. Moreover, LVI variable further improves its predictive accuracy from c-index of 0.76 to c-index of 0.78. LVI variable could be integrated in the COBRA score to optimizing prognosis stratification for patients who undergo RC.

[Diet in the lithiasic patient: A practical guide.] / La dieta en el paciente litiásico:una guía práctica.

The incidence and prevalence of lithiasic disease in developed countries has increased over the last years. Being diet one of the risk factors for urolithiasis, and having it evolved in conjunction with lifestyle over the last decades, such changes could explain the increase in lithiasis case-load. In this article, we analyze how the exercise of the urologist has been regarding the preventive role of diet in the lithiasis patient, what are the scientific evidences on the relationship of diet and lithiasis, and, on this base, what general dietetic recommendations we can give currently to our patients.

La dieta en el paciente litiásico: una guía práctica / Diet in the lithiasic patient: A practical guide

La incidencia y prevalencia de la enfermedad litiásica en los países desarrollados ha aumentado en los últimos años. Debido a que la dieta es uno de los factores de riesgo de la urolitiasis, y tanto esta como el estilo de vida han evolucionado en las últimas décadas, dichos cambios podrían explicarnos el aumento en la causística de la litiasis renal. En el presente trabajo analizamos cuál ha sido el proceder del urólogo en cuanto al papel preventivo de la dieta en el paciente litiásico, qué evidencias científicas existen en cuanto a la relación entre dieta y litiasis y, en base a ello, qué recomendaciones generales dietéticas podemos dar actualmente a nuestros pacientes
